The most abundant of the four major classes of biomolecules, which also include proteins, lipids, and nucleic acids. They fill n

umerous roles in living things, such as the storage and transport of energy (starch, glycogen) and structural components (cellulose in plants, chitin in animals). Additionally, these and their derivatives play major roles in the working process of the immune system, fertilization, pathogenesis, blood clotting, and development.

Answer:

Carbohydrates

Explanation:

Carbohydrate is a macronutrient formed primarily of carbon, hydrogen and oxygen molecules. This macronutrient when ingested and absorbed is responsible for releasing glucose, providing energy to cells as the primary source of cellular energy, and maintaining glycemic metabolic maintenance for the body to continue to function well. Carbohydrates are the most abundant biomolecule present in the body and play a key role in many parts of our body.

Carbohydrates are involved in energy storage and transport, immune system, reproductive system, fertilization, blood clotting, among other processes that are vital in the body.

A researcher creates a mutant pea plant in which cytokinins are overexpressed and gibberellic acid is underexpressed. What is th
Dmitry [639]

Answer:

C) The pea plant would be shorter with more branches compared to wild-type plants.

Explanation:

Gibberellic acid stimulates the stem growth by promoting elongation and cell division, so having this compound's gene underexpressed will make the plant shorter. On the other hand, cytokinins are located in young cells, particularly the buds, and stimulates its lateral growth. Having a plant with a overexpressed cytokinins gene will make the plant have more branches compared to wild-type plants.

In corn, small pollen (sp) is recessive to normal pollen (sp+) and banded necrotic tissue, called zebra necrotic (zn), s ssive t
alex41 [277]

Answer:

Option B

Explanation:

Please see the attached image

Given -

Allele for small pollen is "sp"

Allele for normal pollen is "sp+"

and "sp+" is dominant over "sp"

Allele for zebra necrotic tissue is "zn"

Allele for normal necrotic tissue is "zn+"

and "zn+" is dominant over "zn"

Cross is carried out between

sp+ sp zn+ zn x sp+ sp zn+ zn

The gametes of the parent cells are -

sp+ zn+, sp+zn, spzn+, spzn

The cross would be as follows

         

sp+ zn+ sp+zn spzn+ spzn

sp+ zn+ sp+ sp+ zn+ zn+sp+ sp+ zn+ znsp+ sp zn+ zn+ sp+ spzn+ zn  

sp+zn sp+ sp+ zn+ znsp+ sp+ zn znsp+ sp zn+ zn sp+ sp zn zn

spzn+ sp+ sp zn+ zn+sp+ sp zn+ znsp sp zn+ zn+ sp sp zn+ zn

spzn sp+ sp zn+ zn sp+ sp zn zn sp sp zn+ zn sp sp zn zn

Hence, option B is correct

Describe, and account for the different levels of protein structure. How can proteins serve functions that are so diverse?
Gwar [14]

Answer:

there are four types of protein structure;

  • primary
  • secondary
  • tertiary
  • quatenary

Explanation:

A protein is a very large biological molecule composed of a chain of smaller molecules called amino acids. Thousands of different proteins are present in a cell, the synthesis of each type of protein being directed by a different gene.

Determining the process by which proteins fold into particular shapes, characteristic of their amino acid sequence, is commonly called "the protein folding problem", an area of study at the forefront of computational biology. One approach to studying the protein folding process is the application of statistical mechanics techniques and molecular dynamics simulations to the study of protein folding. Protein folding enables them to perform different diverse functions.

Protein have a three-dimensional structure that enables them to perform diverse functions like transsport,structural support as building blocks and metabolic regulators as enzymes and hormones.

Why is it important for your brain to control many functions automatically?
juin [17]

Answer:

The brain controls what you think and feel, how you learn and remember, and the way you move and talk. But it also controls things you're less aware of — like the beating of your heart and the digestion of your food.

Think of the brain as a central computer that controls all the body's functions. The rest of the nervous system is like a network that relays messages back and forth from the brain to different parts of the body. It does this via the spinal cord, which runs from the brain down through the back. It contains threadlike nerves that branch out to every organ and body part.

Explanation:

If you brain does not, or is unable to perform multiple tasks automatically, you could have trouble breathing on your own, your heart could have problems, even your thought process, movement, and digestion could malfunction. Which could cause a multitude of complications.

Hope this helped, have a great day/night :}
