A friend of yours claims to have identified a gene that causes a human disease! Your friend says that they have sequenced the DN

A of someone with the disorder and compared that to a healthy individual. They found a nucleotide difference in a gene called Hsr12 that encodes a protein whose function is cell-to-cell communication. What is wrong with your friend's claim?

Answer: Point mutation is easily reversible, thus non-lethal

Explanation:

Point mutation is caused by exchange of a single nucleotide for another. These change is called

1) Transition (when a purine base substitute another purine base, or pyrimidine bases substitute each other)

2) Transversion (when a purine base substitute a pyrimidine base).

However, note that a point mutation can be easily reversed by another point mutation; so, the claim that a nucleotide difference in the Hsr12 gene caused the human disease is inaccurate

Which statement is not true of endothermic animals?
ahrayia [7]

Hello! Your answer would be C, They regulate body temperature through behavioral mechanisms.

An endothermic animal is one which is capable of maintaining its own body temperature. They do this through physiological mechanisms, which is what the last choice is saying - these involve things such as hormones, sweating, etc.

These endothermic animals are considered warm blooded. This is because they can make their own body heat. Humans and other mammals are endothermic. We generate our own heat - we don't rely on sunbathing or shade to cool down or heat up our <u>internal</u> body temperature.

Hope this helps!

Answer;

-Reduce the chance of errors in correspondence

-Easier to use for converting between units while measuring

-Make communication easier between scientists comparing data

Explanation;

-The metric system is a system that is based on joining one of a series of prefixes, including kilo-, hecto-, deka-, deci-, centi-, and milli-, with a base unit of measurement, such as meter, liter, or gram.

-Since the metric system is a decimal system of weights and measures it is easy to convert between units simply by multiplying or dividing by 10, 100, 1000, etc.

-It is an alternative system of measurement used in most countries, as well as in the United States.

Nutrients in the deep ocean come from dead marine organisms. <br>True<br>False​
Viktor [21]

Answer:

True

Explanation:

The deep parts of an ocean receive minimal or no sunlight. Hence, the survival of phototropic organisms like plants and algae is impossible or minimal here. Hence, there is a very little diversity in deep oceans. The organisms living here have to feed on dead decaying matter or on each other for survival. Mostly, the organisms living here use dead organisms as food. No other food source is available here.
