Answer:

Anaerobic respiration takes place without the use of oxygen whereas aerobic respiration uses oxygen at the end of the electron transport chain.

Explanation:

Glycolysis can occur without the need or oxygen because it is not needed in the metabolic chain. Glycolysis occurs in the cytoplasm of cell and produces pyruvate as the end products and 2 net ATPs. In the absence of oxygen, pyruvate is converted to lactic acid that is later excreted from the body.

In the presence of oxygen, the pyruvate is converted to acetyl-CoA and enters the Krebs cycle in the matrix of the mitochondria. Here the end products are water (from the reduction of oxygen) and 34 ATPs.

Note that CO₂ is also a byproduct in both Krebs cycle and Glycolysis.

Some mutations result in proteins that function well at one temperature but are nonfunctional at a different (usually higher) te
Vadim26 [7]

Let's complete the question by adding the missing piece of information

The mutation results in the breed's distinctive point markings (ears, mask, tail and legs) and lighter body color. Use this information to explain the pattern of the cat's fur pigmentation.

Answer:

The mutation of the TYR gene results in the enzyme tyrosinase to be heat susceptible. Tyrosinase takes part in the production of melanin to give darker fur in colder areas. The areas like the tail, legs, ears, and face do lack as much body heat and so will get darker.

Explanation:

A unique protein (enzyme), known as tyrosinase, is the major workhorse in the development of the melanin. A research team from the University of California, USA, led by L. A. Lyons, discovered that Siamese cats have tyrosinase that went through mutation due to the changes in the DNA helix and is temperature-sensitive as it's activity reduces with a rise in temperature. This explains why cat’s warm parts of the body are coated with white, melanin-lacking hair since Tyrosinase is deactivated in these regions and melanin is not developed – hair is white-colored. On the other hand, in cooler boundary the enzyme is active and the melanin is formed – hair has dark color.

Do all living cells respire?
myrzilka [38]

Answer:

All living organisms respire. Cells need and use the energy that is formed through this process to assist with life processes in order for organisms to survive and reproduce. Oxygen and carbon dioxide are the main gases involved in aerobic respiration. These conditions are called gas exchange surfaces.

Oxana [17]
Star brightness is defined by either <span>D. apparent magnitude - when we measure it from Earth (that is how bright it is from Earth) - this is the closest to "basic observation" and the best answer

or by absolute magnitute - how bright it would be at a certain distance (this allows to compare the brightness).
