Answer:

Nucleic acids contain the same elements as proteins: carbon, hydrogen, oxygen, nitrogen; plus phosphorous (C, H, O, N, and P). Nucleic acids are very large macromolecules composed of repetitive units of the same building blocks, nucleotides, similar to a pearl necklace made of many pearls

aleksley [76]

Answer:

c. immune functions.

Explanation:

The endocrine system is involved in the regulation of metabolic rate, body temperature (thermoregulation), tissue development and labor contractions except immune functions.

Studies have shown that no hormone has been identified as being important in the regulation of the immune system. Therefore immune functions is not a regulatory function of the endocrine system.

Although, there have been articles on the endocrine and immune system crosstalk, only a hypothesis of various proteohormones not single hormones have been discovered to act on immunocompetent cells.

Whats the difference between genotype and phenotype.

Olegator [25]

$\huge{\green}\fcolorbox{blue}{cyan}{\bf{\underline{\red{\color{red}Answer}}}}$

The genotype is a set of genes in the DNA which are responsible for the unique trait or characteristics.
Whereas the phenotype is the physical appearance or characteristic of the organism.
Thus, we can find the human genetic code with the help of their genotype.
Organisms may look the same but still may not have the same genotype.
One can determine the genotype by the biological tests.
On the other hand, the phenotype is determined by an individual’s genotype and can be expressed as genes or by the visible traits.
Such traits are hair color or type, eye color body shape, and height, and many such more.
It will depend on the genotype but also influenced by the factors existing in the surrounding.

astra-53 [7]

Answer:

During anaerobic respiration lactic acid is produced which is not good for human. It causes muscle pain.

ATP produces during anaerobic respiration are less while aerobic respiration produces more ATPs.

Explanation:

During anaerobic respiration lactic acid is produced which is not good for human. It causes muscle pain.

ATP produces during anaerobic respiration are less while aerobic respiration produces more ATPs.

Aerobic respiration

It is the breakdown of glucose molecule in the presence of oxygen to yield large amount of energy. Water and carbon dioxide are also produced as a byproduct.

Glucose + oxygen → carbon dioxide + water + 38ATP

Anaerobic Respiration

It is the breakdown of glucose molecule in the absence of oxygen and produce small amount of energy. Alcohol or lactic acid and carbon dioxide are also produced as byproducts.

Glucose→ lactic acid/alcohol + 2ATP + carbon dioxide
