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.
Answer:Cattle ranching is the leading cause of deforestation in the Amazon rainforest
Explanation:Colombia, as a signatory to the New York Declaration on Forests, aimed by 2020 to halve natural forest loss and by 2030 to reach net-zero deforestation, meaning that any loss of forest will be offset by the replanting of native forest.
RNA has a ribose sugar instead of deoxyribose sugar like DNA. RNA neucleiotides have a uracil base instead of thymine.
The characteristics that suit a species for survival are transmitted from one generation to the next through genes which are the units of hereditary information.
<h3>What is a Gene?</h3>
This is referred to as the basic functional unit of heredity and is composed of DNA which are passed from the parent to the offspring.
This is done through the process which is known as meiosis in which four unique daughter cells are produced.
This is therefore how characteristics that suit a species for survival are transmitted from one generation to the next through the gene and is the most appropriate choice.
