A geneticist is trying to recreate a strand of DNA from a crime scene investigation. The strand of DNA recovered from the scene was 1800 bases long. The geneticist has determined that the strand contained 425 thymine
nucleotides. Based on this information, identify the number of cytosine nucleotides

Answers

Answer 1

Answer:

475

Explanation:

The strand is only made up of Adenine, Thymine, Cytosine and Guanine. There will be the same number of Adenine as there are Thymine and the same number of Cytosine as there are Guanine.

We know there are 425 Thymine. This means there are also 425 Adenine. Therefore, you would subtract 850 (425x2) from 1800 to find the amount of Cytosine and Guanine left, which is 950.

Out of the 950, half will be Cytosine and half Guanine. 950/2 is 475.

Why would water move faster through one kind of tree compared to another, and what might that tell us about their life cycle and susceptibility to environmental changes?

Answers

Answer:

Due to the presence of larger vessels.

Explanation:

Due to the presence of larger vessels of hardwoods in the tree, water move faster in that tree as compared to other type of plants. in smaller plants, small vessels are present which able them to move less amount of water as compared to large trees which have large vessels. It tells us that the tree adopted the environmental changes so that's why to overcome the change, they use more water.

Environmental conditions often favor one selection over another.



In the context of evolution, selection refers to the process by which certain traits or characteristics become more or less common in a population over time. This process occurs due to environmental conditions that favor certain individuals with advantageous traits, leading to their increased survival and reproduction.

For example, consider a population of birds living in a forest with two distinct color morphs: light and dark. If the forest becomes darker due to increased tree cover, the dark-colored birds might be better camouflaged and have a higher chance of surviving and reproducing. Over time, the proportion of dark-colored birds in the population would increase, as they have a selective advantage in the new environmental conditions.

Similarly, if the forest becomes lighter, the light-colored birds may become more successful in avoiding predation and finding mates. In this case, the environmental conditions would favor the light-colored birds, leading to an increase in their frequency within the population.

Therefore, the term "selection" refers to the process by which environmental conditions favor certain individuals or traits, resulting in changes in the frequency of those traits within a population over time.
