How does a diversity of organisms increase the chances that some will survive a major change in environment ?
Slav-nsk [51]
<h2>Answer:</h2>

This can be explained with an example.

Let’s lake an example of two species 1 and 2.

Species 1 has a wide genetic diversity due to which organism are also diverse in phenotype. Their phenotype are:  

Black, dark brown, brown, dark red, red, light red, pink, skin color.

From left to right organism are becoming less adapted to high temperature relatively.

For species 2:  This species has less genetic diversity and its phenotypic diversity is as follow:

Black, red, Skin color.

From left to right organism are becoming less adapted to high temperature relatively.

Now if there is the sudden high temperature in the environment; 4 Types of phenotype will survive are black, dark brown, brown, dark red.

While there will only two types of organism in specie 2 which will survive are black, red.

So that’s how the diversity of organisms increase the chances that some will survive a major change in environment.

Contact [7]

Answer:

Duplication is a type of mutation that involves the production of one or more copies of a gene or region of a chromosome. Gene and chromosome duplications occur in all organisms, though they are especially prominent among plants. Gene duplication is an important mechanism by which evolution occurs.

I WILL GIVE BRAINLIEST IF IT'S CORRECT
iren2701 [21]

Answer: ATP releases energy when it converts to ADP .

Explanation:

During energy needs, the body cells directs the loss of a phosphate group (Pi) from ATP (Adenosine triphosphate) to yeild ADP (adenosine Diphosphate), and a further loss will yield AMP (adenosine monophosphate). For each loss energy is also released when a phosphate is removed

The reaction involves the addition of water, so it is a hydrolytic reaction, and is catalyzed by enzymes of the mitochondria, and is represented as the equation below:

ATP + H2O → ADP + Pi + free energy
