The hip is an example of which of the following type of joints?

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.

Urea is a nitrogenous waste product that is produced when the liver breaks down proteins and amino acids. It is then excreted from the body via sweat.

Concentration of H+ in the solution = 10 −1 M

pH= -log(10 −1)

pH= -(-1)

The vermiform appendix is a small, finger-like projection that extends from the cecum, which is the first part of the large intestine.

The pituitary gland produces prolactin, which regulates milk production

Biological macromolecules are large organic molecules such as carbohydrates, lipids, nucleic acids, and proteins. They are built from smaller molecules, which are linked commonly by covalent bonds, and these can be broken down.

The renal vein drains deoxygenated blood from the kidneys to the inferior vena cava.

Most of the carbon dioxide from the blood moves into the alveoli through the process of diffusion down a concentration gradient. In the lungs, there is a higher concentration of carbon dioxide in the blood compared to the alveoli. Its molecules, therefore, move from an area of higher concentration (blood) to an area of lower concentration (alveoli) until equilibrium is reached. This is a passive process and does not require energy or carrier proteins.

A chlorine molecule contains the fewest covalent bonds among the options provided. It consists of two chlorine atoms bonded together by a single covalent bond. Compared with the other options, ammonia has three covalent bonds, methane has 4 while water has 2.

A gene is a segment of DNA that codes for a specific protein or polypeptide.
