Epithelial cells .
a. make up the inner layers of connective tissue
b. form adipose tissue, cartilage, bone tissue, and blood
c. are striated
d. are found in the visible portion of hair, fingernails, beaks, or feathers
e. communicate with each other through chemical signals

a. make up the inner layers of connective tissue

Explanation:Epithelial cell are cell made up of inner connective tissues. This tissues helps in absorption of nourishment/ nutrient needed by the epithelial tissue.

They are arranged into sheet and joined to each other. This special properties aids it function.

Epithelial cell have modified surface structurally and through internal modifications this aids there ability for absorption and secretion of some glands such as liver, digestive tract and also act as barrier.

They form a sheet of cell called epithelia that serves as linning for body surfaces.

They can be classiified into three bases the shape on how the cells are packed;

Squamous epithelium- They are usually wider. They can be found in blood vessels

Cuboidal epithelium are almost similar in height and width

Columnar exceptionally are Tall and wide.

choices:

a. g2. b. g1. c. m

cell division has two checkpoints namely, g1

checkpoint and spindle assembly checkpoint. the checkpoint which determines if

division has properly occurred is the g1 checkpoint. at this point, is a damage

in the dna is detected or  the has not reach the optimum size, the cell is

stopped in g1 and is not allowed to proceed to further process.

hey bro i looked it up on google the structure of the eye-spot in euglena viridie, e. ehrenbergii, and phacus pyriyorme is not as franzé haa described it. the so-called “crystal body” and “lens bodies” were not found in any of the individuals of the species examined by me. as earlier observers have stated, the eye-spot consists simply of a mass of pigment granules arranged in a single layer, and probably embedded in a protoplasmic framework, but the latter could not be seen, and its presence was only inferred from the fact that the pigment granules must be held together in some way, thd the eye-spot as a whole is capable of expansion, and that the pigment granules can be separated from each other.

hope this   and an i get brainlsiest
