This is an example of Codominance inheritance
Explanation:
A correlation among pair of variants of a gene is termed as Codominance. Unit version of a gene is obtained by individual, designated an allele, from all parent. The ruling allele will be revealed,when the alleles are varied. They are screened if they are the outcome of the additional allele, termed recessive.
The appearance of the a allele is not disguised by another allele is the concept of Codominance . When specifying alleles for codominance, the code is to practice a standard character to express dominant and recessive and do superscripts to describe the various codominant alleles.

what is the role of RNA in protein production
Answer:
Ribosomal RNA (rRNA) associates with a set of proteins to form ribosomes. These complex structures, which physically move along an mRNA molecule, catalyze the assembly of amino acids into protein chains. They also bind tRNAs and various accessory molecules necessary for protein synthesis.
Explanation:
The fundamental role of RNA in protein synthesis is to create proteins via translation. It carries genetic information that is translated by ribosomes into various proteins necessary for cellular processes.
What is Protein synthesis?Protein synthesis may be defined as the process through which cells construct proteins. It takes place in two stages. They significantly include transcription and translation. It balances the loss of cellular proteins through the production of new proteins.
Transcription is the transfer of genetic instructions in DNA to mRNA in the nucleus. While translation is the methodology through which a cell makes proteins using the genetic information carried in messenger RNA (mRNA). mRNA, rRNA, and tRNA are the three main types of RNA involved in protein synthesis.
Therefore, the fundamental role of RNA in protein synthesis is to create proteins via translation.

I 7
Explanation:
This is an animal cell because it is shown to be rounded or curved (whereas plant cells would have straight lines as the outer layer). Cells are made up of parts called organelles, which are what we are labelling.
A 1 Nucleus
The nucleus is the "control centre" of the cell and where DNA is stored. It is typically drawn to be round and having another circle inside it (nucleolus).
B 3 Rough Endoplasmic Reticulum
The Rough ER (for short) is part of the transport system of the cell. It has ribosomes unlike the smooth ER, which makes it "rough" (notice the small dots on the structure). Ribosomes are partially made in the rough ER.
C 9 Plasma Membrane
The plasma membrane is the outermost protection layer for the cell. It controls what comes in and goes out of the cell and also provides a structure. It may also be called the "semi-permeable membrane" because it only allows some substances to pass through it.
D 8 Cytoplasm
The arrow seems to be pointing to an empty space of purple, and this purple is found throughout the entire cell like a background. The cytoplasm suspends all other organelles, allows movement within the cell and provides structure.
E 5 Golgi apparatus
Also known as the "golgi body", its job is to package proteins and prepare them for transport. It often looks like a stack of something in side view.
F 6 Mitochondria
The mitochondria is the powerhouse of the cell because it's where cellular respiration happens (produces energy). It usually is drawn with squiggly lines inside an ovular shape.
G 2 Ribosome
Ribosomes is where protein synthesis happens. They are found all over the cell and are really small. They begin their journey in the nucleus, travel through the rough ER, are packaged in the golgi apparatus, then directed to where they are needed.
H 4 Smooth Endoplasmic Reticulum
The smooth ER (for short) is also a part of the transport system. Unlike the rough ER, it does not have ribosomes. Its jobs include regulating calcium levels and making lipids (fat).
I 7 Lysosome
Lysosomes are like Lysol (if this helps you remember). It does the "cleaning" in the cell. It has enzymes that digest dead organelles and food.
An event lasts 4 hours and 20 minutes. How long did the event last in seconds?
a) 14,400
b) 15,600
c) 72,000
d) 86,400
The event last in 15,600 seconds.
Answer: Option B
Explanation:
We know that there is 60 seconds in one minute i.e., 1 minute = 60 seconds
There is 60 minutes in one hour. i.e., 60 minutes = 1 hour.
Given : An event lasts 4 hours and 20 minutes
4 hours contains 240 minutes,
[tex]4 \times 60=240 \text { minutes }[/tex]
When the above expressed in seconds,
[tex]240 \times 60=14400 \text { seconds }[/tex] ------>eq. 1
When 20 minutes expressed in seconds,
[tex]20 \times 60=1200 \text { seconds }[/tex]------->eq. 2
Adding both eq. 1 and 2, we get
4 hours and 20 minutes = 14400 + 1200 = 15600 seconds

Cause of death to the cell wall
The causes of death to cell wall includes imbalance of electrolytes and Some antibiotic classes .
Explanation:
The layer that encapsulates the membrane of the cell is called cell wall. The structure of the cell wall may vary from flexible to rigid. It supports the cell in two different ways. It protects a cells and it helps in forming their structure. Cell walls are not present in animals. Cell walls are present in eukaryotes and prokaryotes.
Cell wall helps the cells to prevent the expansion of cells beyond certain size, when there is an entering of water happens. When there is no balance between the electrolytes then death of cell wall happens. It ca also cause due to antibiotic classes. These will restrict the synthesis process of those blocks that builds cell wall.
during dry weather , the water level in a small pond drops because of runoff
FALSE.
during dry weather , the water level in a small pond drops NOT because of runoff but RATHER because of EVAPORATION.
Explanation:
Dry weather means there is little;e relative humidity in the air mass the region. Therefore, more water from the pond easily evaporates because of the air’s high capacity to hold more moisture before getting to saturation. This is why water levels in water in small ponds lower or even dries up in dry conditions during the dry season. The warmer air temperatures increase the capacity of the air to hold more moisture hence evaporation of water from the ponds is increased.

Final answer:
The water level in a small pond decreases during dry weather primarily due to runoff and evaporation. Runoff causes water to flow out of the area, while evaporation removes water from the pond's surface. Understanding these processes is crucial for water management and ecosystem conservation.
Explanation:
The question relates to the process by which the water level in a small pond decreases during dry weather, with a particular focus on the role of runoff. Runoff is the movement of water across the land's surface, leading to its flow out of an area. This can occur due to various reasons including rainfall, snowmelt, or additional water from irrigation not absorbed by the soil. During periods of dry weather, the absence of rainfall reduces the recharge of the pond through direct precipitation. Meanwhile, existing water may continue to evaporate or infiltrate into the ground, especially if the surrounding soil becomes dry and capable of absorbing more moisture.
Additionally, evaporation plays a significant role in the reduction of water levels in a pond, particularly during times when temperatures are high, and the air is dry. Plants surrounding the pond contribute to water loss through transpiration, a process where water is absorbed by their roots and then lost to the atmosphere from their leaves. It's crucial to understand these natural processes to appreciate the dynamic nature of pond ecosystems and the factors that influence water levels. These insights are essential for effective water management and conservation strategies to maintain biodiversity and ecosystem health.
How are antibiotics able to target the bacteria cells but not the healthy cells within your body?
Antibiotics target cells based on the morphology.
Antibiotics target special protein and lipid receptors on the cell walls of bacteria.
Antibiotics target cells with chemical and UV damage.
Healthy cells lack the endospores that antibiotics target.
Answer: is Antibiotics target special protein and lipid receptors on the cell walls of bacteria.
Explanation:
Human cell do not contain cell wall. Cell wall is the outer layer present outside the cell membrane in plants, bacteria, and fungi. Cell wall present in plants, bacteria and fungi give extra protection to the cell. Antibiotics helps to stop the bacteria from building a cell wall. Antibiotics contain penicillin which works against bacteria cell to form a cell wall. In bacteria protein synthesis is essential part of cell, there are many antibiotics which stops the process of protein synthesis by cutting the protein chain in bacteria cell to stops it's further growth to make it difficult to sustain.
The correct option is A. Antibiotics target cells based on morphology. Antibiotics target bacterial cells by exploiting structural differences, such as the presence of peptidoglycan in bacterial cell walls and differences in ribosome structures.
Antibiotics are able to target bacterial cells without harming healthy human cells primarily due to the differences between prokaryotic and eukaryotic cells. One key aspect is the presence of peptidoglycan in bacterial cell walls, which is absent in human cells. Many antibiotics, such as penicillins and cephalosporins, work by interfering with the synthesis of peptidoglycan, weakening the bacterial cell wall and leading to cell lysis.Additionally, antibiotics like macrolides and tetracyclines target the bacterial ribosome, which is structurally different from the ribosome found in human cells. These antibiotics can inhibit protein synthesis in bacteria without affecting human cells. Therefore, the specificity of antibiotics for bacterial structures ensures that they can effectively target bacterial infections while sparing human cells.Thus the correct option is A. Antibiotics target cells based on the morphology.
The diagram displays the copying of a DNA sequence from a gene before and after the copy is made. The * represents an error that was made. Identify what this error is called. A) replication B) recombination C) point mutation D) transfer mutation
Answer:
The correct option is C) Point mutation
Explanation:
A mutation can be described as any change or error which occurs in the DNA of a person. A point mutation can be described as a kind of mutation in which only one of the nucleotide base is changed, added, or deleted from a certain point of the DNA. The consequences of the point mutation depend on the nucleotide being changed and the difference it makes on the codon sequence. if a point mutation occurs in an intron region then it will be less likely to be harmful.

What is the probability that a female child of Charles and Marie would suffer from hemophilia?
0 percent
25 percent
50 percent
100 percent
Answer:
The correct option is A) zero percent
Explanation:
Hemophilia can be described as an X-linked recessive disorder in which the blood of a person is not able to clot properly. As it is a recessive disorder, both the alleles should be recessive for the disorder to occur. In males, as only one X chromosome is present hence, only one allele would be enough to cause the disorder in males. Whereas for females, both the X chromosomes will have to carry the recessive type alleles for the disorder to occur.
The correct answer is 0 percent.
Hemophilia is a genetic disorder that is inherited in an X-linked recessive pattern. Charles and Marie are the parents in question, and since hemophilia is X-linked, it is important to consider the sex of the child and the genetic makeup of the parents.
Charles, being a male, has only one X chromosome. If he has hemophilia, it means his X chromosome carries the hemophilia gene. Marie, as a female, has two X chromosomes. Since the question does not mention Marie having hemophilia or being a carrier, we will assume she is neither.
Here are the possible genetic combinations for their children:
- A female child (XX) will inherit one X chromosome from each parent. Since Marie's X chromosomes are normal and Charles can only pass on his Y chromosome or his X chromosome with hemophilia, the possible combinations for a female child are:
- X^N (from Marie) + X^h (from Charles) -> X^N X^h (carrier)
- X^N (from Marie) + Y (from Charles) -> X^N Y (not possible since this would result in a male child)
- A male child (XY) will inherit the X chromosome from his mother and the Y chromosome from his father. The combinations are:
- X^N (from Marie) + Y (from Charles) -> X^N Y (unaffected)
- X^h (from Marie, not possible since she is not a carrier) + Y (from Charles) -> X^h Y (hemophilia, not possible since Marie is not a carrier)
Since Marie is not a carrier, she will always pass on a normal X chromosome to her daughters. Therefore, a female child of Charles and Marie cannot suffer from hemophilia because she will either be a carrier (with one normal X from Marie and one X with hemophilia from Charles) or unaffected (with two normal X chromosomes, one from each parent). The probability of a female child being unaffected is 100 percent because she will always receive a normal X chromosome from her mother.
In summary, the probability that a female child of Charles and Marie would suffer from hemophilia is 0 percent.

traits that have three or more phenotypes may be the result of alleles
Answer:
Traits that have three or more phenotype may be the result of multiple alleles.
Explanation:
When three or more alternative genes occupies the same locus then it is known as the multiple alleles.Normally only two type of alleles are found in an organism.The multiple alleles results in the formation of appearance of multiple looks in an organism (phenotype).The blood type in human beings are the common example of multiple alleles (ABO system of blood groups is controlled by three alleles).
A scientist injected a drug into a mouse that inhibits the formation of mRNA in either the sperm or egg cells.
What could be the result of this alteration?
Answer:
The mouse will not be able to form sperm or egg or abnormal sperms or egg will be formed.
Explanation:
For the synthesis of proteins, the DNA is transcribed and an mRNA is formed. This mRNA is translated by the ribosomes and a protein is formed. If mRNA is not formed, then the protein will not be able to form.
If the formation of mRNA is inhibited for the sperm or egg cells they will either not form the right kind of sperm or egg cells or will not produce them at all depending on the mRNA that is being inhibited from the formation.

-->fish is commonly used but dangerous as you can contract mercury poisoning
Fluorescent dyes are the most likely products to have been created through marine biotechnology, specifically organobromine compounds like Tyrian purple from marine organisms. The correct answer is option c) Fluorescent dyes.
The product that was likely created through marine biotechnology is fluorescent dyes. Specifically, the organobromine compounds derived from marine organisms have been used historically, with the most famous example being Tyrian purple, a dye extracted from marine gastropods since ancient times.
Despite products like penicillin, plasma television, and lithium batteries being significant in their own right, they were not directly a result of marine biotechnology. Penicillin, for example, was discovered as a secretion of the fungus Penicillium and not from marine organisms.
Thus, the correct answer to the student's question is option c) Fluorescent dyes.

0
D. Monoculture crops can be easily wiped out by new diseases.
Answer:
bcd
Explanation:
Reduced biodiversity and modern farming practices lead to environmental damage including deforestation and pollution, while posing health risks due to growth hormones and pesticides. Genetic homogeneity from monoculture farming increases vulnerability to diseases. These factors contribute to a decline in ecological systems and soil productivity.
Explanation:Reduced biodiversity and modern farming practices present significant dangers to both the environment and human health. One major concern is the loss of land through deforestation to construct new farms which can lead to habitat destruction and a decrease in biodiversity. This deforestation is a major factor in the increase of greenhouse gases and can cause soil erosion and reduced rainfall.
The use of growth hormones in livestock and the contamination of our food and water by pesticides and nitrates are potential health hazards. The sub-therapeutic use of antibiotics in animal production is an area of active research, as it may be affecting human health. Furthermore, the excessive use of chemical fertilizers results in pollution of the environment, contributing to issues like eutrophication and dead zones in water bodies due to nutrient runoff.
Another problem is monoculture farming, which creates genetic homogeneity, leading to increased vulnerability to diseases that could potentially wipe out entire crops. Overall, modern agricultural practices have profound impacts on ecological systems, soil productivity, water quality, and the diversity of species upon which we rely for a stable food source.

When an apple is cut, oxygen comes in contact with the fruit’s inner tissue and browning occurs. One particular enzyme in the apple cells, polyphenol oxidase, begins breaking down the tissue. This process may be the plant’s way of keeping pests away from a cut or broken area. What could you do to stop this browning action?
Answer: The cut slices should be refrigerated to slow the reaction. Also, you can coat them with lemon or pineapple juice.
Explanation: The acids in these juices slow the reaction and the antioxidants inhibit it.
Final answer:
To stop the browning action when an apple is cut, you can limit its exposure to oxygen, use antioxidants, and use ethylene blockers. These measures will help prevent the activity of the enzyme that causes browning and preserve the appearance of the cut apple.
Explanation:
To stop the browning action that occurs when an apple is cut, you can take a few measures:
Limiting exposure to oxygen: Browning is caused when oxygen comes into contact with the fruit's inner tissue. You can prevent this by placing the cut apple in an airtight container or wrapping it tightly with plastic wrap to limit its exposure to oxygen.
Using antioxidants: Browning is also caused by the enzyme polyphenol oxidase. Antioxidants, such as ascorbic acid (vitamin C), can inhibit the activity of this enzyme and prevent browning. You can apply lemon juice or a mixture of lemon juice and water to the cut apple to provide a source of antioxidants.
Using ethylene blockers: Ethylene is a gas that is released by the apple when it is cut, and it promotes browning. You can use ethylene blockers, such as ethylene-absorbing packets or a solution of citric acid, to prevent ethylene from reaching the cut apple and reduce browning.
