Answer:
no cell wall, only plasma membrane
cleavage furrow
Explanation:
The animal cells are different from the plant cells in many ways. The specific characteristic features of the animal cell include the absence of the cell wall, and the formation of the cleavage furrow during the cell division.
The animal cells only have plasma membrane around them. No large hypertonic vacuole is present. The chlorophyll and chloroplasts are present in the plant cells and not in the animal cells. The cell plate is formed in the plant cells during the cell division. In the animals, a cleavage furrow is formed instead of the cell plate.
mitosis produces daughter cells
B. an area of sand dunes
C. an oasis
D. a valley in a desert setting
a double helix best describes the structure of the sides of the DNA molecule. The correct option is A.
Thus, Deoxyribonucleic acid, or DNA, has a double helix-like structure. It is made up of two lengthy nucleotide strands that are spirally coiled around one another.
The complementary nitrogenous bases adenine (A) and thymine (T) and cytosine (C) and guanine (G) form hydrogen bonds that hold the two strands together.
This double helix structure is frequently compared to a spiral staircase or a twisted ladder.
Thus, a double helix best describes the structure of the sides of the DNA molecule. The correct option is A.
