A study found two processes. Process A and Process B, are to be correlated.

Which of the following is true for these processes?

Psoriasis is a chronic skin condition that causes red, scaly patches on the skin. It is not contagious, and it is not caused by any microorganism. It is believed to be an autoimmune disorder where the immune system attacks healthy skin cells.

Cardiac muscles have intercalated discs that enable them to contract in a coordinated manner. Skeletal muscles do not have intercalated discs, as their contraction is under voluntary control and does not require the same level of synchronization seen in the involuntary contraction of cardiac muscle.

Rationale

Chromatin refers to a complex of DNA and proteins in human cells. This material is packaged by histones to make up the chromosomes. The chromosomes then contain genetic information that is heritable.

Crushing a solid reactant into powder increases the surface area of the reactant, thereby increasing chemical reaction. This is because more of the reacting molecules or ions are exposed to the other reactant, which increases the chance of particles colliding and leads to more successful collisions per second.

The pituitary gland produces prolactin, which regulates milk production

The parathyroid hormone (PTH) from the parathyroid glands is important in serum calcium regulation. It increases blood calcium levels by stimulating osteoclasts to break down bone and release calcium into the bloodstream. PTH also enhances the absorption of calcium from the intestines and the kidneys.

Melanocytes are specialized skin cells that produce melanin, which is the protective skin-darkening pigment. They are found mainly in the epidermis, though they occur elsewhere, such as in the hair.

Water has a high specific heat capacity, which means it can absorb and store a large amount of heat energy without significantly changing in temperature. This helps moderate the temperature fluctuations of the air near the coast, as water can store heat during the day and release it at night, or vice versa.

The digestive system breaks down complex food substances into small and less complex absorbable compounds. Proteins, for instance, are broken down to constituent amino acids through a digestion process that combines mastication and enzymatic breakdown.

Rationale

Atoms are the smallest and most basic units of matter, and they can combine to form molecules. Cells are the basic units of life, and they are made of molecules. Tissues are groups of cells that work together to perform a specific function, such as muscle tissue or nerve tissue. Organs are collections of tissues that form a larger structure.
