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.
Animals, including plants and some other microbes, get energy directly from the sun. But when they’re INDIRECTLY getting energy from the sun, they eat other organisms, like plants and/or meat.
Answer:
I don't think so but u have to find out for your self
Answer:
based on a tested hypothesis
Explanation:
Laws are generally <u>based on tested hypotheses</u>.
Theories are first derived from repeatedly tested and proven hypotheses. Scientific laws are derived from theories that have been proven to be true over a wide range of phenomenon. Hence, laws are overwhelmingly proven facts that <u>cannot be changed</u>.
Scientific laws are <u>internally consistent</u>, compatible with evidence, and are <u>testable against a wide range of phenomenon</u>. However, <u>they can be reviewed</u> as more evidences emerge that have not been known before.
