The answer is A. Ketones
2 : production of energy
3 : replication of genetic material
4 : recognition of certain chemicals
Cell membrane helps in the recognition of certain chemicals.
Further Explanation:
Plasma membrane is an outer boundary of the cell. It is composed of phospholipids and proteins. It is also called selectively permeable membrane because it allows only selective substances to cross. The transportation of these molecules from extracellular fluid to intracellular fluid is called cellular transport. It can be active and passive transport. Active transport required energy for the movement of substances, whereas in passive transport the molecules move across the membrane without using energy.
There are three common cellular substances that can pass through cell membrane are water, carbon di-oxide and oxygen. These substances are transported through passive transport. The carbon di-oxide and oxygen move through the area of higher concentration to lower concentration. The oxygen diffuses into the cell through lipid bilayer because it is more concentrated outside the cell, whereas carbon dioxide diffuses out of the cell because it is more concentrated inside the cell.
Water moves through the membrane by the process called osmosis. It moves freely either through protein channels or by slipping between the lipid tails of the membrane. The water comes from higher concentration to lower concentration.

The cell membrane functions to recognize certain chemicals. Option 4 is correct.
Carbohydrates, proteins, and lipids are found on the cell membrane. Carbohydrates are covalently attached to proteins on the cell membrane to form glycoproteins. Lipids are attached to glycoproteins to form glycolic acid. These are called membrane carbohydrates. Most membrane carbohydrates are found on the surface of the cell and extend to the extracellular compartment. These membrane carbohydrates play an important role in the recognition of cells.

b. Coral reefs provide aquatic organisms with resources but derive no benefits in return.
c. Coral reefs provide resources for aquatic organisms and derive resources from other organisms as well.
d. Aquatic organisms live independently of coral reefs.
The correct answer is - c. Coral reefs provide resources for aquatic organisms and derive resources from other organisms as well.
The corals are essential part of the marine ecosystems. They are feeding upon zooplankton, but also their polyps get sugar that is produced by the algae living on them. Also, the corals provide much needed shelter for lots of marine animals, but also are on the menu of some, like the starfish for example.
The pituitary gland's secretions are regulated by the hypothalamus. The correct answer is Option 4: Hypothalamus.
The hypothalamus, a diminutive region positioned beneath the thalamus in the brain, assumes a crucial role in governing the secretions of the pituitary gland.
Working in close tandem with the pituitary gland, the hypothalamus acts as a master regulator of hormonal balance in the body.
Through the release of its own distinct hormones, the hypothalamus effectively manages the pituitary gland's secretion of an array of hormones.
These hormones, in turn, wield authoritative influence over numerous physiological processes within the body.
By orchestrating this intricate interplay, the hypothalamus serves as a pivotal control center, overseeing and modulating essential bodily functions such as growth, metabolism, stress response, and reproductive functions.
This partnership between the hypothalamus and the pituitary gland underscores their pivotal roles in maintaining overall hormonal equilibrium and homeostasis.

Answer: The gland that controls the secretions of the pituitary gland is the hypothalamus.
Explanation:
The hypothalamus is a key regulatory structure in the brain that releases hormones and neurotransmitters that influence the secretion of hormones from the pituitary gland, which is often referred to as the "master gland" because it controls the function of many other endocrine glands in the body.
