Molecules are made up of atoms. Atoms are the building blocks of molecules

As such, comparing both on the basis of similarities and differences looks like the comparison of house with walls of a house

A house requires some number of walls and specific arrangements of walls.
Similarly a molecule requires number of atoms and the arrangements of atoms.


Atoms and molecules both are neutrals.
Some atoms are stable like Helium etc. and mostly molecules are also stable
Both atoms and molecules react with each other and other molecules and atoms.
An Atom is electrically neutral but molecule is not electrically neutral

Structurally, they are rather different. It’s somewhat hard to compare and contrast them.

Hypersecretion of prolactin from the anterior pituitary gland causes the condition of ________. dwarfism postpartum hemorrhage g
kolbaska11 [484]

Hypersecretion of the population from the anterior pituitary gland causes the condition of galactorrhea.

Prolactin is another name is called luteotropin and its main function is to enable mammals mostly female to produce milk. The pituitary gland secretes it in response to mating, estrogen treatment, ovulation, nursing and eating.

The pituitary gland is attached to the hypothalamus by a short stalk. The pituitary gland has two major parts.

(i)                  An anterior lobe

(ii)                Posterior lobe.

The pituitary gland is controlled by hormones and neurons that comes in the hypothalamus where it acts as a link between brain and endocrine system, and hypothalamus is the endocrine gland itself. Hypothalamus has neurons which regulate secretion of anterior lobe hormones by secreting inhibit and releasing  hormones. Every hormone produced by anterior lobe has a releasing hormone.

Prolactin and growth hormones have inhibiting hormone. Releasing hormone helps in stimulating production and it releases hormones from the anterior lobe.

In C3 plants the conservation of water promotes _____.
bija089 [108]

Answer:

The correct answer is d. photorespiration

Explanation:

In the C3 plant, the Rubisco enzyme is important that fix CO2 into organic molecule by binding with CO2. Rubisco can also bind to oxygen when the oxygen concentration increases in cells which leads to the loss of fixed CO2  and waste of energy which is called photorespiration.

So when stomata are open CO2 comes in and O2 goes out of the cell which maintains the high CO2 concentration in the cell but during hot days C3 plants close stomata to prevent water loss.  

So closing of stomata decrease the intake of CO2 and increase the oxygen concentration inside the cell. So in increased temperature and high oxygen concentration, the rubisco enzymes bind to O2 and promote photorespiration.

What is the relationship between anabolism and Catabolism
Leni [432]

Answer:

Difference Between Catabolism and Anabolism. Both anabolism and catabolism are metabolic processes, but the two are contrastingly different from each other. • Catabolism produces energy but anabolism uses energy. • In the catabolic pathways, the large molecules are broken down into small monomers whereas, in anabolism, small molecules are connected with each other, to form large molecules
