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

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.

A large gradient for sodium exists across a cell membrane. Channels are opened and sodium diffuses freely through the channels.
skelet666 [1.2K]

Answer:

Once the sodium channels opens and sodium is allowed to diffuse freely in and out of the cell, this will cause a large change in entropy and enthalpy. Values for both these quantities will increase significantly, however, the change in free energy will be small when we compare the open and closed state of the sodium channel. With regards to the stability of the system, it will reach equilibrium because the concentration of sodium ions is being allowed to diffuse without any regulation.

Hope that answers the question, have a great day!

An adult female client describes the pain in her hand as having an audible grinding and cracking sound, especially in her thumb
slamgirl [31]

Answer: The correct answer to the question is option C

OSTEOARTHRITIS.

The client has a degenerative form of disease that is evidenced by osteoarthritis.

Explanation: Osteoporosis is otherwise known as degenerative joint disease.

In a healthy joint,a protective cartilage cushions the end of bones(articulating bones) and as well acting as a shock absorber.

In osteoarthritis,these cartilage that acts as a cushion to the bones wears down down or generates with time exposing the joint and the bones predisposing them to mild to moderate friction that occurs as a result of mobility of the bones/joint.

Osteoarthritis mostly affect joints of the hips, hands,spine and knees.

Some of the common symptoms of Osteoarthritis are;pain in the joints of the hands,knees,hips,lower back and neck with crackles,stiffness and tenderness of the joints which often results to difficulty in walking and deformity of the joint if left untreated.

The ability of a person's cardiovascular system to compensate for blood loss is most related to?
amid [387]

The ability of a person's cardiovascular system to compensate for blood loss is most related to how rapidly he or she bleeds.

<h3>what is cardiovascular system made up of?</h3>

Your cardiovascular system, which consists of your heart and blood arteries, is an essential component of your body. When your cardiovascular system is functioning properly, your cells receive a constant supply of oxygen and nutrients from your blood. Carbon dioxide and other waste are also removed via blood vessels. You have the ability to maintain your heart and blood vessels healthy. Eating healthy foods, exercising, keeping your blood pressure and cholesterol under control, and quitting smoking are all beneficial to your cardiovascular system. Request assistance from your provider in achieving heart health.
