Answer:
A. diploid and C. somatic
Explanation:
Humans are diploid organisms and have 23 pair of chromosomes i.e. in total humans have 46 chromosomes.
There are 2 types of cells in humans (1) somatic cells and (2) germ cells.
Somatic cells are normal body cells which are diploid and have all 23 pairs of chromosomes. But, germ cells are special type of cells which are produced by gonads (sex organs). Germ cells are also known as gametes. In females, ovary is the sex organ which produces germ cells named as egg cells while in males testes is the sex organ which produces germ cells named as sperms. Germ cells (egg and sperm) are haploid cells which fuse to form a zygote which is the first cell of next generation. The process of fusion of egg and sperm is known as fertilization which is responsible for restoring diploidy in the progeny which receives half the genetic material from female parent and half the genetic material from male parent.

Ball and Socket Joint
This type of joint allows for a wide range of rotation and movement. The shoulder and hip are ball and socket joints.
A cell membrane protects a cell from it's surroundings. The cell membrane controls the movement of substances from the outside and inside of cells and organelles.
Scientists change the names of taxonomic groups to match the current nomenclature is probably NOT a reason for these changes.
Scientists change the names of taxonomic groups to match current nomenclature.
<u>Explanation:</u>
There are various main reasons why taxonomists from time to time require or choose, to modify the name of an organism such as a plant. Initially, the naming of plants is treated by a set of laws ( the International Code of Botanical Nomenclature ) which sets out how to accurately name plants and how to solve cases where two or more names have been used for one species.
It seldom happens that applying the rules requires us to change a name. For example, if a species named by one botanist turns out to have been before legitimately named by an elder botanist.
