What are some ways in which the structure of a compound influences its function?

Answers

Answer 1
Answer:  structure of a compound influences its function in many ways like we take example of phospholipid bilayer  1. The fact that the tails are hydrophobic means that they do not interact with water. When a bunch of phospholipids are floating around in water, they try to arrange themselves in a bilayer that shields the hydrophobic parts from water-based, or aqueous, surroundings.

2. The heads are hydrophilic and can then interact with water and other polar or charged substances on either side of the bilayer. The bilayer acts as a barrier that allows cells to maintain internal conditions that are different from external conditions, which is monumentally important for cells to operate properly. 

3. Phospholipids demonstrate the intersection of structure and function in another way, too. We already know that fatty acids can be saturated or unsaturated and that unsaturated fatty acids have bends in their chains. Those bends prevent fatty acids from packing close.

Mangrove pneumatophore roots _______.a.
prop the trees up above the water line
b.
excrete excess salt
c.
absorb carbon dioxide from the air
d.
none of the above

Answers

Correct answer: A). Prop the trees up above the water line

Mangrove pneumatophore is the specialized root structures that are known to grow out of the water surface and help in the respiration of mangrove plants. They allow the collect oxygen from the atmosphere.

It mainly grows in mud and there the conditions are anaerobic means lack of oxygen. Oxygen is necessary for their survival that is done by the mangrove pneumatophore roots.  

Hence, the correct answer would be option A.

Final answer:

Mangrove pneumatophore roots mainly prop the trees up above the water line to intake necessary oxygen from the air for survival, but they do not practically absorb carbon dioxide from the air.

Explanation:

Mangrove pneumatophore roots have a distinctive function in the survival of Mangrove trees in their saline, oxygen-poor environments. The correct answer to your question is that mangrove pneumatophore roots indeed prop the trees up above the water line (option a). These roots emerge from the water, allowing Mangrove trees to intake the necessary oxygen for survival. While they also partake in the limited excretion of excess salt, their main function is undeniably oxygen absorption from the air and supporting their physical structure.

However, the roots do not absorb carbon dioxide from the air (option c). Thus, although options a and b reflect partial truth, option a accurately captures the characteristic function of pneumatophore roots.

 the answer is D) multiple alleles

5. Suppose a dominant allele (N) codes for a big nose and a recessive allele (n) codes for a small nose. Imagine that an organism receives a dominant allele from its mom and a dominant allele from its dad. What can be determined about its genotype and phenotype?

Answers

The genotype of the organism receiving these 2 alleles from its parents respectively, would be NN. Homozygous Dominant.

The offspring phenotypically for one of its characteristics would have a Big Nose.

Which is NOT an important step in pollination? A. An insect drinks nectar from a plant B. Pollen sticks to the insect’s legs C. The insect travels to another plant to deliver the pollen.

Answers

Answer:

A. An insect drinks nectar from a plant

Explanation:

Even though this is a bit important its really not, all its doing is just drinking which the pollen sticks to them as they move to a different flower .
