<span>The function of most proteins depends primarily on the:
1. Organism. Its habits and environment.
2. Type of amino acids.</span>
1. The population is under selection pressure from predators
<span>2. Hey now, no population is ever at H-W equilibrium: </span>
<span>mutations happen </span>
<span>immigration and emigration can occur </span>
<span>the population is not huge, which means that genetic drift can happen </span>
<span>mating is not completely random -- a rat is more likely to mate with someone local than with someone living in Paris, France. </span>
<span>b) The small rats will be selected for (assuming there are predators in this ecosystem that are less likely to look in bushes, and further assuming that the small rats do not have reduced fertility by dint of being small) </span>
<span>This is "directional selection" </span>
<span>c) I would expect the "smallness" allele frequency to increase in this population over time, and the "normal size" allele frequency to decrease.</span>
Hi There! :)
<span>When light energy excites electrons in photosystem 2, where do the electrons to replace them come from?
</span><span>ATP</span>
I think that’s true!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Answer:
B. The planets vary in size and composition.
Explanation:
Galileo was an Italian scientist and he was the first person to use a telescope in the field of astronomy. Although, the first telescope was invented by Sir Isaac Newton.
A telescope can be defined as an optical instrument or device which comprises of a curved mirror and lenses used for viewing distant objects i.e objects that are very far away such as stars and other planetary bodies.
One of the first astronomers to use a telescope was Galileo. Using his telescope he discovered that Jupiter had four moons and each night, the four moons, seen as points of light, appeared to change positions slightly. Therefore, this observation gave further evidence that the planets vary in size and composition. The slight change in the position of the moon indicate that planetary bodies have a variation in size and matter (constituent elements) that make them up.
