mixer [17]

Answer:

The correct answer is C) ensures the continued existence of the human species.

Explanation:

The human reproductive system is responsible for the production, storage, and transfer of gametes to the next generation. In the male reproductive system, testes make gametes and in the female reproductive system, ovary makes gametes.

The reproductive system in humans ensures the continued existence of human species in this world because the reproductive system is responsible for gamete fusion and new offspring developments which are more adapted in the environment. This ensures the existence of humans on earth.

What are the two autotrophic forms of metabolism​
cricket20 [7]
Autotrophic behaviour depends on the ability of the cell to carry out photosynthetic or aerobic respiratory metabolism, which are the only processes able to deliver sufficient energy to maintain carbon fixation. The Calvin cycle is used by bacteria to synthesize organic compounds.

Why are unsaturated fatty acids particularly abundant in the cellular membranes of antarctic fish?
Nutka1998 [239]
Antarctic fish species requires an adaptation to cold environment. Living at cold temperature environment would demand certain biological responses such as cutaneous respiration, enlarged blood vessels, and producing greater amounts of fat. Most of these fat are composed of higher phospolipid levels which are primarily due to phosphatidylethanolamine. This phospolipid is responsible for destabilizing cell membranes and make it more fluid thereby allowing unrestricted blood flow. The fatty acid composition of the membrane lipid is important for membrane fluidity, this is mainly attributed to unsaturated fatty acids which are responsible for decreasing the order of membrane lipids thereby decreasing viscosity. At extremely low temperatures, organisms with low concentration of unsaturated fatty acids would freeze cell membranes. That's why antarctic fishes have higher levels of unsaturated fatty acids.

What ia rock?<br>give answer​
Maru [420]
A rock is a hard/solid material. Rocks are separated into different groups based off the minerals they have in them, the groups are metamorphic, igneous, and sedimentary. Rocks are formed by physical changes—such as melting, cooling, eroding, compacting, or deforming—that are part of the rock cycle.

Which phrase listed below best describes the function of the digestive system?
xz_007 [3.2K]


The best answer is C - to break down food into nutrients.

The digestive system  breaks down food  into its simplest form that cell are able to utilize  for energy.  Food is broken down into its monomer units. Proteins are broken down into amino acids, lipids are broken down into fatty acids and glycerol and carbohydrates are broken down into glucose.

Glucose is then absorbed into the blood and transported to every cell in the body. The cells take in glucose and use it as fuel and raw material  in the process of cellular respiration. From one molecule of glucose, 36 to 38 molecules of ATP ( the form of energy used by cells) are produced.
