Question: What are linked genes?
Answer: genes on the same chromosome that are inherited together
Explanation: this is because these genes are not inherited by themselves
question answered by
(jacmorris04)
Linked genes are genes on the same chromosome that are inherited together during cell division because they are located closely together. These genes often lead to unique patterns of inheritance.
Explanation:Linked genes are genes that are located on the same chromosome and thus are likely to be inherited together during the cell division process. This is because they are situated so close to one another on the same chromosome that they do not separate independently, a key tenet of Mendelian genetics. Because of this, linked genes often show genetic traits or phenotypes that violate the principle of independent assortment, leading to unique patterns of inheritance.
For example, in fruit flies, the gene for eye color and the gene for wing size are linked genes. This means that if a parent has red eyes and large wings, their offspring are much more likely to also have red eyes and large wings because these traits are often inherited together due to the close proximity of their respective genes on the chromosome.

Which is an advantage of using space observatories for space exploration?
It allows scientists to avoid the effects of light pollution
Answer:
The correct answer is that it allows scientists to avoid the effects of light pollution.
Explanation:
There are many causes why space observation is anticipated in order to prevent the issues, which the terrestrial observatories exhibit. An illustration of this is that the space observatory does not have to face the involvement of city lights, thus preventing light pollution.
In supplementation, the thermal turbulence found in the atmosphere also does not affect the image of a telescope. The terrestrial observation exhibiting the shape of a sphere functions as a lens, which distorts the images. Thus, the resolution of the terrestrial images exhibits a substantial diminution.

A biologist wishes to take a useful gene found in pine trees and introduce it into some bacterial cells. Her experimental procedure is given below.
1. Use a restriction enzyme to cut a gene out of pine tree DNA.
2.Use a restriction enzyme to cut open a plasmid.
3.Treat the plasmid with DNA polymerase.
4.Introduce the plasmid into bacterial cells.
Which step shows an error in the biologist's procedure?
Answer:
3.Treat the plasmid with DNA polymerase.
Explanation:
DNA polymerase will not be useful in this step of the experiment.
In the third step of the experiment shown in the question above, it would be correct to use the enzyme called ligase, so that the plasmid was linked to the pine gene.
DNA polymerase cannot make this binding since the function of this enzyme is to allow DNA replication. As the polymerase was used in the third step of the experiment, the scientist will not succeed when trying to introduce the plasmid into bacterial cells, since this plasmid does not have the pine gene.

how does light intensity affect the rate of photosynthesis
Hi
Photosynthesis is the process through which green plants make their own food. There are many factors that can affect the process of photosynthesis both positively or negatively. Some of these factors are light intensity, concentration of carbon di oxide, temperature and can be water sometimes.
How light intensity affects photosynthesis:
As we have studied from childhood that process of photosynthesis occurs in the presence of light, so if the intensity of light will increase obviously the rate of photosynthesis will speed up and become fast.Similarly, if the light intensity will be low it will badly affect the rate of photosynthesis and plants will suffer from growth and development related problems due to lack of sufficient food.Now what happens if the intensity of light is very high, ofcourse it will increase photosynthesis but not always. Why? Because along with light plant also needs CO2 and water for the process of photosynthesis to occur. If light is available in sufficient amount but CO2 or water is not available in sufficient amount then it can become a hindering factor and it is not sure that photosynthesis will increase.Other than that, extremely high intensity of light can also negatively effect photosynthesis and cause some problems like bleaching of chlorophyll where plants are unable to prepare food in a well manner.There is another interesting fact about light, that its wavelength also effects the photosynthesis differently. In attached image you can see how photosynthetic pigments chlorophyll a and b absorb light differently during photosynthesis.Hope it helps!
If DNA has the sequences of bases TCAAGT, the mRNA formed during transcription would have the sequence of
A. UCAAGU
B. AGTACA
C. AGUUCA
Answer:
The correct answer is option C. "AGUUCA".
Explanation:
When mRNA is synthesized from a DNA sequence, the RNA polymerase catalyses the addition of nucleotides in the process known as transcription. During the synthesis the RNA polymerase adds the complementary sequence of the DNA template, with the only difference that molecules of uracil are added instead of the molecules of adenosine. Given that adenosine binds to thymine, and cytosine binds to guanosine, the mRNA formed from the DNA sequence "TCAAGT" will be "AGUUCA".
All climates in the southern hemisphere are warmer than those in the northern hemisphere (1point)
The statement ''All climates in the southern hemisphere are warmer than those in the northern hemisphere'' is false.
While it is true that the southern hemisphere generally experiences warmer temperatures during its summer months (December to February) due to its closer proximity to the sun, it is not accurate to say that all climates in the southern hemisphere are consistently warmer than those in the northern hemisphere.
The temperature variations across both hemispheres are influenced by various factors including latitude, altitude, proximity to large bodies of water, ocean currents, and prevailing winds. For instance, regions near the equator in both hemispheres tend to have warmer climates year-round, while polar regions experience colder temperatures. Additionally, factors such as the presence of mountain ranges, desert regions, and ocean currents can lead to significant temperature variations within each hemisphere.Therefore, while some climates in the southern hemisphere may indeed be warmer than their northern hemisphere counterparts, it is not universally true for all climates, making the statement false.
Complete question:
All climates in the southern hemisphere are warmer than those in the northern hemisphere.

Scientists have noted a decline in the number of all mushroom species dating back to the early 1900s. In addition, annual crops of edible mushrooms in France and Germany have declined since 1950. One hypothesis explaining the decline is that edible fungi are being overharvested. Global warming and air pollution have also been considered as part of the problem. What evidence helps to exclude overharvesting as the cause of the overall decline? A) a similar decline in edible North American mushrooms B) absence of mushrooms near coal-burning powerplants in Indonesia C) increase in mushroom species in a region of tropical South America D) declines in poisonous, non-edible mushroom species in cool climates
The correct answer should be D.) Declines in poisonous, non-edible mushroom species in cool climates. Although question B does provide evidence that Global warming could be the cause of the declines, it still doesn't disprove the theory that overharvesting could be the cause as well. Question C could be caused by a number of things, such as deforestation, a local change in climate, removal of agricultural pests, ect. Question A supports the hypothesis that overharvesting is the cause of the decline, instead of disproving it. Hope this helped!
The decline in poisonous, non-edible mushroom species in cool climates helps to exclude overharvesting as the main cause of the overall decline in mushroom species, suggesting that overarching environmental issues like global warming and air pollution are more likely causes.
Explanation:The evidence that helps to exclude overharvesting as the cause of the overall decline in the number of all mushroom species is option D) declines in poisonous, non-edible mushroom species in cool climates. This implies that overharvesting of edible mushrooms is not likely the main cause because even the non-edible (which are not harvested) are in decline. This explanation suggests that overharvesting, which would primarily affect edible species, is not the only factor. Instead, overarching environmental issues, like global warming and air pollution, which would affect all types of mushrooms regardless of their edibility, are more likely causes of the decline.

Explain how changes in the DNA sequences will impact the expression of genes.
Ans.
DNA acts as genetic material in all living organisms that store and transmit genetic information from one to next generation. DNA sequence carries instructions for the expression of genes to make proteins, responsible for different phenotypic characters of individuals.
The DNA, first synthesizes mRNA molecule that carry information for the protein synthesis, in the form of codons and code for a specific polypeptide chain or protein.
The sequence present in DNA determines the amino acid sequence in protein encoded by the DNA. Change in DNA sequence affects gene expression as it leads to change in mRNA sequence, and thus, change in sequence of amino acid of the resulting protein.

Answer: B. Erosion
Explanation:
Weathering is a process of physical disintegration of the rocks or other materials present over the earth crust into small particles or sediments due to a physical agent such as water or wind. The erosion is the process of mechanical or physical removal of the top layer of the soil or any surface material and transportation of the material to the other location. Mass wasting is the process in which unstable materials get dislocate from their place due to the effect of gravity.
Erosion is caused by the combination of physical factors like wind, water and gravity.
What does a burning candle have in common with a cell preforming respiration? Select all that apply.
A.Both release energy
B.Both use carbon doixide
C.Both use oxygen
D.Both release oxygen
Final answer:
Both a burning candle and a cell performing respiration release energy and use oxygen, but they do not both use or release carbon dioxide. A burning candle actually produces carbon dioxide as a byproduct, and while cells utilize carbon dioxide during photosynthesis, they do not use it during respiration.
Explanation:
The question asks about the commonalities between a burning candle and a cell performing respiration. First, let's identify the options:
Both release energy
Both use carbon dioxide
Both use oxygen
Both release oxygen
The correct answer choices are:
A. Both release energy: In a burning candle, the chemical reaction involves the combustion of wax (which contains carbohydrates similar to glucose) with oxygen to produce carbon dioxide and water, along with energy in the form of light and heat. In cellular respiration, cells use oxygen to convert glucose into carbon dioxide and water, while energy is stored in molecules of ATP.
C. Both use oxygen: Oxygen is necessary for both processes; it is consumed within the combustion process in a candle, and cells use oxygen in the mitochondrial oxidative phosphorylation to extract energy from glucose.
Both B and D are incorrect:
B. Both use carbon dioxide: Cells utilize carbon dioxide during photosynthesis, not respiration. In the case of a burning candle, carbon dioxide is the product, not a reactant.
D. Both release oxygen: Neither a burning candle nor cellular respiration releases oxygen; they both consume it.

What ions are produced from acids and from bases
When dissolved in water, acids dissociate to produce hydrogen ions, while bases dissociate to produce hydroxide ions. For example, hydrochloric acid yields hydrogen and chloride ions, while sodium hydroxide yields sodium and hydroxide ions.
Explanation:Acids and bases interact with water to produce certain ions. In water, acids dissociate to produce hydrogen ions (H+), whereas bases dissociate to produce hydroxide ions (OH-). This behavior forms the basis of the Arrhenius definition of acids and bases. For example, hydrochloric acid (HCl) is a common acid that when dissolved in water will dissociate into hydrogen ions (H+) and chloride ions (Cl-). Conversely, sodium hydroxide (NaOH) is a typical base that will dissociate into sodium ions (Na+) and hydroxide ions (OH-) when dissolved in water.

Acids produce hydrogen ions [tex](H^+)[/tex], while bases produce hydroxide ions [tex](OH^-)[/tex] when dissolved in water.
An acid is a substance that can donate a proton (H^+) to another substance, which is known as a Bronsted-Lowry acid. When an acid dissolves in water, it dissociates into its constituent ions, releasing hydrogen ions (protons) into the solution. For example, hydrochloric acid (HCl) dissociates into H^+ and Cl^- ions in water:
[tex]\[ \text{HCl} \rightarrow \text{H}^+ + \text{Cl}^- \][/tex]
On the other hand, a base is a substance that can accept a proton (H^+) from another substance, which is known as a Bronsted-Lowry base. When a base dissolves in water, it dissociates to produce hydroxide ions (OH^-). For instance, sodium hydroxide (NaOH) dissociates into Na^+ and OH^- ions in water:
[tex]\[ \text{NaOH} \rightarrow \text{Na}^+ + \text{OH}^- \][/tex]
In summary, the characteristic ions produced by acids and bases in aqueous solutions are hydrogen ions (H^+) for acids and hydroxide ions (OH^-) for bases. These ions are responsible for the acidic and basic properties of the respective solutions."
