xxMikexx [17]

Answer:

The correct answer will be option-Yes--every species represents a resource that may be exploited by an array of parasites

Explanation:

Parasites are the organism which for survival depends on the resources of the host organism and utilize them to the extent that it could lead to the death of the host.

The interaction between the parasite and host proves harmful to the host but beneficial to the parasite.

A number of parasites exist for human species which can directly harm humans. Similarly, a large number of hosts exist for different species which belongs to another kingdom also like even the bacteria has a parasite called bacteriophage which utilizes the resources of the host.

This indicates that every species has some resources which can prove beneficial to another organism in the response of which they become host to a large number of parasites.

Thus, the selected option is the correct answer.

Why is a "shell of hydration" important to life?
Vitek1552 [10]

D. It allows a variety of substances to dissolve in and around cells.

Explanation:

The shell of hydration is important to life because it allows a broad range of substances to dissolve in and around the cells.

  • The shell of hydration allow for water to dissolve a wide range of substances and disperse them uniformly in it.
  • Water serves a solvent capable of dissolving a wide range of substances because it forms a hydration shell round them.
  • This allow for materials to be in solution around the cell.
  • Diffusion and osmosis can readily now take place.

A goal of using animal models is to explain the molecular detail of specific behaviors encoded in the human brain. How would you
oksian1 [2.3K]

Answer:

It is possible to compare the expression of homologous genes in the brain of <em>D. melanoganster</em> and humans, because the expression levels of conserved genes may be associated with the evolution of cognitive features such as complex learning and memory.  

Explanation:

Model organisms can be used to understand the patterns and processes that affect human evolution. <em>Drosophila melanogaster </em>is a model organism that has been used to study expression patterns of conserved genes in the course of evolution. This model organism has also been used to develop genetic mutant lines in order to examine the role of genes evolutionarily conserved in animals, including those involved in neurocognitive development.

In genetic research, an experiment as the above described is framed in a research field named 'Behavioral Genetics', which is a discipline that studies how evolutionarily conserved gene networks may be associated with neurocognitive tasks during brain evolution.
