Answer:
Due to increasing the survival.
Explanation:
The natural selection causes a change in allele frequency leading to a change in the color of the frogs because the colour of the frog helps it in hiding from predators. The population of that frog specie increases which has the ability to hide from the predators in that environment while on the other hand, the population of frog decreases which can easily be seen by the predator due to its colour so this change in allele frequency will leads to natural selection.
The answer is radioisotopes as this has the ability of
breaking molecules apart and aside that, it has the ability of destroying cells
and as well as having to damage living tissues in the body because these are
isotopes that are unstable.
Answer:
74%
Explanation:
The frequency in such cases (diallelic cases) is estimated by following formula which is attached in the image:
So as per our question, the frequency of the "R allele" as per data given below will be as under:
58 red-phase (RR)
32 cross-phase (RS)
10 black/silver-phase (SS) foxes
Total plants = 58 + 32 + 10 = 100
f(R) = 58 x 2 + 32/ 2 (58+32+10)
= 116 + 32 / 200
= 148/200
= 0.74 i.e. 74%
Answer:
<em><u>Nutrients help break down food to give organisms energy</u></em>
Explanation:
Nutrients are chemical substances found in every living thing on Earth. They are<em> necessary</em> to the lives of people, plants, animals, and all other organisms. <u><em>Nutrients help break down food to give organisms energy</em></u>. The human body can also synthesize some nutrients, such as <em>amino acids</em>.
