Answer: Animal cells divide by a cleavage furrow. Plant cells divide by a cell plate that eventually becomes the cell wall. Cytoplasm and cell membranes are necessary for cytokinesis in both plants and animals.
Explanation:
Visual traits, like cell shape and size, are the most important criteria for determining similarity between species. thus option C is correct.

What is the significance of numerical taxonomy?</h3>
In biological systematics, numerical taxonomy is a categorization scheme that deals with the numerical grouping of taxonomic units according to their character states. Instead of employing a subjective assessment of their qualities, it seeks to construct a taxonomy using numerical procedures like cluster analysis.
The data produced can effectively be used in the design of better keys and classification systems because numerical methods are more sensitive in delimiting taxa. Numerous biological ideas that have long been accepted have been reexamined in the context of numerical taxonomy.

Answer:
A.it pumps hydrogen ions inside the cell
Explanation:
Principally, the main role of electron transport chain is to maintain the electrochemical gradient of hydrogen ions (H+) inside the mitochondrial matrix. This is the last step in aerobic cellular respiration and performs a series of redox reactions. Overall, it allows accumulation of H+ inside the mitchondrial matrix. This increased gradient or accumulation of hydrogen ions (H+) is essential because H+ would accept the electrons producing during the reactions. Without this, the flow of electron will be stopped because of high gradient, and production of ATP will not happen as well.
Indeed ETC helps in production of ATP but that is not the main function of electron transport chain rather it is a function of mitochondria.
The fluid-mosaic model describes the plasma membrane of
animal cells. The plasma membrane that surrounds these cells has two
layers (a bilayer) of phospholipids (fats with phosphorous
attached), which at body temperature are like vegetable oil (fluid).
And the structure of the plasma membrane supports the old saying, “Oil
and water don’t mix.”
Each phospholipid molecule has a head that is attracted to water (hydrophilic: hydro = water; philic = loving) and a tail that repels water (hydrophobic: hydro = water; phobic
= fearing). Both layers of the plasma membrane have the hydrophilic
heads pointing toward the outside; the hydrophobic tails form the inside
of the bilayer.
Because cells reside in a watery solution (extracellular
fluid), and they contain a watery solution inside of them (cytoplasm),
the plasma membrane forms a circle around each cell so that the
water-loving heads are in contact with the fluid, and the water-fearing
tails are protected on the inside.
The answer would be C.
