The energy acquired in the light-dependent reactions is used in the light-independent reactions to build glucose molecules. How is this energy transferred from light-dependent to light-independent reactions?
Question 9 options:
in the bonds of ATP and NADPH molecules
in the bonds of 5-carbon ribulose molecules
in the bonds of 3-carbon phosphoglycerate molecules
in the bonds of carbon dioxide molecules
Answer:
The energy obtained in light independent molecules are depend on ATP and NADPH to produce glucose from carbon dioxide molecule.
Explanation:
Photosynthesis is a process done by plants that have 2 stages - Light dependent reaction and Light independent reaction (Calvin cycle). In light dependent reaction,the light energy is converted into chemical energy with the help of ATP (adenosine triphosphate) and NADPH ( nicotinamide adenine dinucleotide phosphate) which is used in Calvin cycle that uses those energy obtained from light dependent reaction and produce glucose with the help of carbon dioxide.Steps-(Light dependent reaction)
Chlorophyll absorb sunlight⇒convert it into chemical energy⇒formation of ATP & NADPH
(Light independent reaction)
ATP+NADPH+ Carbon dioxide= Carbohydrate(Glucose)
Why would farmers want to farm near rivers even with the potential of the river flooding???????????
Answer:
The answer is to increase crop growth.
Explanation:
Farmers construct a man made channel leading water from the river to their crops. When farming near rivers the soil is good enough for planting. Many bugs animals poop their which help grow the plants and they are watered daily. After you plant the crops you are basically done. And the River is a Natural source of water so their are no worries of daily watering because nature is doing it for you. Even tho flooding can happen they have sand bags and walls that they set up to control this.

Answer: Explanation:
We have two sets of chromosomes because we're diploid organisms: the most obvious function of this is that two parents can mix and match their genes in (figurative) hopes of getting some optimum combination in at least some of their offspring.
Hope this helps!!!!
Each human cell only has 1 set of 23 chromosomes. The only time it gets 2 is when it is about to divide and copies its DNA (go through mitosis and cytokinesis). When the cell splits, each daughter cell will have 1 set of 23 chromosomes again.

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.
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.

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.

B. healing wounds effectively
C. replacing lost cells, such as shed skin cells
D. preventing communication among cells
Answer:
The answers are letters B and C.
Explanation:
"Multicellular organisms" are those organisms with many cells. Examples of these are kelp and Volvox.
In order for multicellular organisms to grow, they have to undergo a process called "mitosis." This is a type of cell division which allows the number of chromosomes to be maintained (such as the parent nucleus) in the resultant cells (identical cells).
The division aids in the organism's growth and repair, thus wounds are healed effectively. It also allows the replacement of lost cells, such as shed skin cells because the organism can regenerate cells when the need arises.
In contrast to unicellular organisms which uss cell division for reproduction, multicellular organism use cell division for "healing and repair" as well as "regeneration."

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.

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.

SUBMIT
During Prophase chromosomes condense, and mitotic spindle form, chromosomes are copied, and the nuclear membrane disappears, spindle fibres pull the sister chromatids apart.
Explanation:
Prophase is divided into 2 sub-phases as early Prophase and late prophase.
Early Prophase:
In early prophase distinct thick chromosome like structures, Centrioles move to the opposite poles and, nuclear membrane disappears
By late prophase:
Astral rays and spindle fibres are formed. Spindle fibres attach to the chromosome. Contractions occur in the attachment and sister chromatids are pull apart towards the equator.
Metaphase will follow the prophase.
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.
Why are some rivers still able to flow during times of drought???????
Answer:
"Due to the increased temperature the snow starts melting and more water gets deposited in the upstream that flows downwards" as a result of which rivers flow in drought condition.
Explanation:
During hotter days, snows begins to melt hence the river gets more water when compared to the other seasons of the year. But in some case the rivers only rely on the rainfall which often gets dry due to lack of proper rainfall. In some cases it has also been seen that, in spite of low rainfall the river still continue to flow because of the presence of more water in the upstream that begins to flow towards the downward stream having larger basins.
