Answer:

food molecules become digested once there is a concentration gradient to drive diffusion, the nutrients need a path across the membrane. fats and fat soluble nutrients can move directly across the lipid membrane. water, gasses ane other very small molecules can diffuse through the pores of the cell.

DanielleElmas [232]

The endomembrane system is very important for synthesizing, processing, and movement of lipids and proteins in the cell.
The smooth ER function is mainly used for lipid synthesizing and processing, while the rough ER function is for protein synthesizing

1. The following statement is similar to those you might see on exams. Write a paragraph of 3-5 sentences describing 1) whether

yanalaym [24]

Answer:

The oxygen dissociation curve represents the percentage saturation of Hb with oxygen at different partial pressure of oxygen. The different partial pressures gives sigmoid shapes to the curve. When this curves shifts to right, it indicates low affinity or binding of oxygen by the Hb. it also indicates the unloading or releases of Oxygen by Hb molecules at condition of low pressure. e,g in the muscles during strenuous exercise.However, when the curve shifts to the left, this indicate high affinity for oxygen, great binding, at high partial pressure of oxygen.e,g in the lungs to take oxygen and releases CO2.

Therefore in this scenario, the statement -. <u>During strenuous exercise, the oxygen-hemoglobin dissociation curve shifts to the right.</u> is correct. because oxygen is needed by the muscles therefore ,oxygen should be less binded by Hb, decrease affinity and easily unloaded to muscles.

<u>The statement </u>This rightward shift reflects an increase in the affinity of hemoglobin for oxygen and favors loading of O2 into hemoglobin in the lungs is wrong.

As explained above the rightwards shift indicated low affinity of Hb for oxygen(unloading)and favours unloading at the muscles because during strenuous exercise the partial pressure of oxygen is very low(but that of CO2 high) in the muscles which favours low oxygen molecules binding by Hb, and easy release to respiring cells.

On the Pacific island of Guam, large herbivorous bats called "flying foxes" commonly feed on cycad seeds, a potent source of neu

Bad White [126]

Flying foxes disperse the Cycad seeds if the seed sometimes get swallowed whole.

Explanation:

Cycads are gymnosperms they do not have seeds enclosed in fruit. Therefore the bats are not attracted to cycad fruit.
If the bats were susceptible to neurotoxin then they must not have been the frequent feeders of cycad seeds. Biomagnification of neurotoxin in flying fox is a widely researched topic.
Beetles do not have an association with these bats thus the bats must not be assisting them as important pollinating agents.

The broadest way to classify the nervous system is to differentiate between the ______ nervous systems.

ankoles [38]

Answer:

Central and Peripheral

Explanation:

The nervous system is divided into two parts: the central nervous system and the peripheral nervous system. The central nervous system includes the brain and spinal cord.

On the other hand the peripheral nervous system includes all of the nerves that branch out from the brain and spinal cord and extend to other parts of the body including muscles and organs. Each part of the system plays a vital role in how information is communicated throughout the body.

The below diagram provides a schematic view of the role of each sub-division of the Nervous System.
