An isolated African canyon community in which cheetahs and leopards consume only impala antelopes is being observed. In a hypoth
ss7ja [257]

Answer:

<em>The population of the impala antelopes will decline rapidly.</em>

Explanation:

The cheetahs and leopards are the predators of the impala antelopes. If the population of the predators arises, this means there will be more predators feeding on the prey. As a result, the population of the prey will decline. Hence, in the above scenario, the population of the impala antelopes will decline rapidly as it will have more number of predators. The population of the cheetahs might also start to decline if it does not move on to another source of food.

Each of the tissues listed below has a specialized function that is linked closely to the structures found within the tissue's c
ivann1987 [24]

Answer:

Insect flight muscles [Mitochondria]

Cells lining the respiratory passages [Cilia]

White blood cells that engulf and destroy invading bacteria [Lysosomes]

Leaf cells of cacti [Chloroplasts]

Goblet cells lining the intestinal tract that secrete mucus [Golgi apparatus]

Pancreatic cells that are responsible for creating several digestive enzymes (proteins) [Ribosomes]

Explanation:

Mitochondria are cell organelles whose main function is energy generation during respiration. They generate energy in the form of ATP which is then used by the cells and tissues for various metabolic function. Mitochondria are abundant in cells whose energy requirements are high such as muscle cells. Therefore, insects flight muscles will have an abundance of mitochondria.

Cilia are finger-like projections on respiratory surfaces whose sweep-like movements help to move particles and fluids out of the airways. In the trachea, the cilia trap particles like bacteria and viruses and then move these trapped particles along with mucus up to the pharynx where it is either coughed out or swallowed into gastrointestinal tract. Therefore, respiratory surfaces like the trachea will have an abundance of cilia.

Lysosome are cell organelles which function to destroy and digest foreign and cellular proteins in the cell. They have an abundance of proteolytic enzymes which degrade proteins at acidic pH. Therefore, white blood cells that engulf and destroy invading bacteria will have an abundance of ysosomes.

Chloroplasts are plant cells organelles which are the sites for photosynthesis. It is abundant in the leaves of plants where photosynthesis mainly take place. Therefore, leaf cells of cacti will have an abundance of chloroplasts.

Golgi apparatus is a cell organelle that helps process and package proteins and lipid molecules, especially those that are to be secreted outside the cell, packaging them into vessicles. They also make and secrete mucus. Therefore, goblet cells lining the intestinal tract that secrete mucus will have an abundance of Golgi apparatus.

Ribosomes are cell organelles whose main function is to synthesize proteins, both for intracellular and extracellular purposes. Proteins such as hormones, enzymes etc, are synthesized by the ribosomes. Therefore, pancreatic cells that are responsible for creating several digestive enzymes (proteins) will have an abundance of ribosomes.
