Answer:
If larger seed became available, directional selection will act in favor of bigger beak finch.
Explanation:
In the case that more large seeds were to become available, then directional selection will start to influence in the beak size, favoring those individuals with bigger beaks. Those individuals with shorter beaks will start to disappear as these animals won't be able to eat the larger seed.
Directional selection <em>increases the proportion of individuals with an extreme phenotypic trait,</em> in this case, large beaks.
This selection presents more frequently in those cases in which <em>interactions between living organisms and the environment</em> modify in the same direction.
This information can be useful to agriculture because bees are major pollinators of crops, so it is important to know which pesticides to manage in order to avoid risk to bee survival. That is option B.
Bees are one of the social insects that lives in societies that are based on a caste system.
Each caste performs a special task or series of tasks that serves as an economic importance to the agricultural system.
Pests such as parasitic mites cause poor agricultural yield. By using pesticides, which are protective chemicals, farmers have greatly improved crop yield.
The bee workers while in search of pollen from crops can be harmed from the pesticides that is being used to control parasitic mites. This can lead to Colony collapse disorder of the caste system of bees.
Therefore, it is important to know which pesticides to manage in order to avoid risk to bee survival.

Answer:
Stereo microscopes, also called low-power microscopes, dissection microscopes, or inspection microscopes, are designed for viewing "large" objects that are visible to the naked eye at low magnifications (under 50x). A stereo microscope provides an upright and unreversed, 3-dimensional image of the specimen.
Explanation:
Answer:
Because it is also one of the larval stages in some other groups of invertebrates, and are used by biologists to deduce evolutionary relationships among different groups of invertebrates
Explanation:
hope it will help you.
Afferent nerve fibers carry signals from the somatic receptors to the posterior horn of the spinal cord or to the brainstem. So i beleive it is 4 but not too sure. Hope this helped a bit (:
