Answer:
Organisms whose life history is subject to K-selection are often referred to as K-strategists or K-selected. Organisms with K-selected traits include large organisms such as elephants, humans, and whales, but also smaller, long-lived organisms such as Arctic terns, parrots and eagles.
Explanation:
Cellular respiration is the process by which cells in plants and animals break down sugar and turn it into energy, which is then used to perform work at the cellular level. The purpose of cellular respiration is simple; it provides cells with the energy they need to function.

The correct option is C.
Plasmodesmata are microscopic channels which are found in plants and some algae, these channels transverse the cell wall of plant cells and enable transportation and communication among cells. Plasmodesmata allow molecules to move directly from one cell to another cell.
Answer:
Mitochondria in brown fat have the ability to produce heat without the need to produce ATP molecules
.
Explanation:
Hibernating bats develop brown fat on their backs between the shoulder blades, but mammals can also store brown fat in their bellies and other parts of their bodies
.
This characteristic that bats and other animals that hibernate possess gives you the possibility of producing energy without the production of ATP through cellular mitochondria.
That is to say, the brown adipose tissue - the main heat-generating organ in the body and is activated with the cold - is also an endocrine organ that secretes signaling factors that activate the metabolism of fats and carbohydrates. The brown adipose tissue helps "burn more calories" and produce body heat from fat.
