1/4 recessive can be expected for the recessive trait of mono hybrids from the F2 generation.
Option D
<h3><u>
Explanation:</u></h3>
Mono hybrid cross is defined as the crossing between two plants considering the two different alleles of a particular character. It was 1st performed by Father of Genetics, Sir Gregor Mendel. The mono hybrid cross done by him considered the character tallness of garden pea plants, of which one was tall and other was short.
He crossed them to get all tall plants in
Filial generation. Now as he self bred those plants, he got the tall and short plants in ratio of 3:1. Thus he proved that the recessive trait of mono hybrids is
of the total population of F2 generation.
Answer:
Regulate heat throughout it's body,
Explanation:
Countercurrent Heat Exchange is a normal and varied mechanism in organisms that utilizes parallel pipes of flowing fluid in opposite directions in order to save energy, such as blood flow. For example, a whale's tongue uses this system through the blood flow to the tip of the tongue, where the countercurrent heat exchange system heats up blood returning to the body.
