Select the pair of structures that best shows how plant cells are different from animal cells. a. cytoplasm and mitochondria b. chloroplasts and cell walls c. nuclei and centrioles d. ribosomes and cell membranes

B. chloroplast and cell wall.

Explanation:

Cell wall is the outer envelop structure which cover a plant cell. It provides a plant cell it's structure and rigidity. It is made up of rigid polysaccharide such as cellulose, pectin or hemicellulose. It protects the cell from the external environment. It prevents the entry of large molecules that can be toxic to cell.

Chloroplast is an organelle in the plant cell which consists of green pigement chlorophyll. This pigment absorbs the light energy from sun which is necessary for the process of photosynthesis in green plants.

Both cell wall and chloroplast are specialized structures present plants but not in animals.

answer: c

explanation:

as the gila monster consumes the eggs or young of the desert cottontail and gambel's quail, thus its main food supply is only accessible for a restricted time duration every year. however, for this, the gila monsters exhibit three adaptations, which elevate their survival rate in the desert condition.  

first, is that they possess huge bodies, and can consume greater concentrations of food during a small period. secondly, they require to feed infrequently as they can accumulate fat in their tails. ultimately, their rate of metabolism is very low, so that they can burn their reservoirs of fat gradually.
