Answer:

Acquired (or somatic) mutations occur at some time during a person's life and are present only in certain cells, not in every cell in the body. These changes can be caused by environmental factors such as ultraviolet radiation from the sun, or can occur if an error is made as DNA copies itself during cell division.

If two species have many amino acid differences, are they closely or distantly related? Explain how scientists know this.
devlian [24]
Different amino acids means difference DNA sequences, which means they are distantly related.

Further understanding: if you look at identical twins, they are closely related to each other because they have almost the same DNA, which will code for the same amino acids, which will lead to the same phenotype or appearance.

To summarize, the greater the amino acid differences the less related they are and vice versa

Hope that helps

Which statement best descibes a cause and effects that occurs during the process of muscle contration?
ExtremeBDS [4]
The most appropriate statement that is explaining the effect and cause during muscle contraction is. “The release of calcium ions causes myosin and actin to attach to each other.” The activation of muscles helps in the generation of muscles that send out the signals to the neurons.

In this lab, you used a dichotomous key to identify organisms. Why would this skill be valuable to you? Check all possible reaso
Oliga [24]

The reason why a dichotomous key to identify organism is valuable, is because it helps you classify organisms,it helps you identify eco -systems, it helps you analyze an organism's traits.

Explanation:

A dichotomous key is a skill that has been brought about by scientists, to help people to identify and classify organisms.

In Dichotomous key, the main way of identifying an object is by it scientific name.This is because, though two objects might look similar to each other but they might belong to a whole different species.

So, it is is easier to identify the organism from its scientific name, as it will tell us which species it belongs to.

This key is very useful to people who are novice, and don't know much about identifying an organism.

This key also helps identifying, whether an organism belongs to a particular closely related group of organisms or is a separate organism.

It helps one analyze the traits of an organism, and based on their characteristics, it will help you identify and classify the species of the object or organism.

Lostsunrise [7]
<span>The situation is one similar to the development of antibiotic resistance. The initial five years of spraying wiped out most of the pests; however, the killing also helped the pesticide-resistant pests to survive and thrive since they had less competition. Over the period of five years, the pesticide resistance became more and more common among the beetles and in the eighth year, almost all of the beetles were resistant to the pesticide. Thus, the answer is D.</span>
