Cilia are a. similar to the bacterial flagella in that they rotate to allow motion. b. are temporary extension of the cytoplasm, used only for movement when resources are low. c. composed of microtubules arranged in a 9+2 (9 surrounding, 2 central) manner. d. composed of microfilaments arranged in a 9+2 (9 surrounding, 2 central) manner.

Explanation:

In many organisms, the function of cilia is same to flagella. It helps in the movement of organisms from one place to another in search of food and some other reasons.

Cilia is madeup of microtubules which are arranged in 9+2 form. 9 pairs of microtubules are present in fused form outside the cylinder while 2 microtubules are present in the center in unfused form.

gametes or germ cells are haploid cells (example: sperm and ova) containing only one set (or n) number of chromosomes and autosomal or somatic cells are diploid cells containing 2n number of chromosomes.

one characteristic that is shared by all is a soft body. many

of these invertebrate animals also have an outer shell to protect their

body. oysters, clams, snails, and mussels are all mollusks. so are octopuses, squids, and slugs. mollusks live on land and in freshwater.
