In peas, tall plants (T) are completely dominant over short plants (t). You cross two heterozygous pea plants Use a Punnett squa

Nikitich [7]

Answers and Explanation:

Find enclosed the Punnet square.

T= dominant allele

t= recessive allele

Tt= heterozygous genotype

TT and tt= homozygous genotype

- The male pea plant's genotype is Tt (heterozygous)

- The female pea plant's genotype is Tt (heterozygous)

- Male gametes: T and t

- Female gametes: T and t

- The expected genotypic ratio of the offpring will be:

TT: Tt: tt ⇒ 1: 2: 1

1/4 of the offpring will be TT genotype (dominant homozygous), 1/2 of the offpring will be Tt (heterozygous) genotype and 1/4 of the offpring will be tt genotype (recessive homozygous).

- The expected phenotypic ratio of the offpring will be:

tall : short ⇒ 3 : 1

3/4 of the offpring will be tall (TT and Tt) and the restant 1/4 will be short (tt).

Explain how ATP stores and releases energy

atroni [7]

Answer:

The ATP molecule can store energy in the form of a high energy phosphate bond joining the terminal phosphate group to the rest of the molecule. In this form, energy can be stored at one location, then moved from one part of the cell to another, where it can be released to drive other biochemical reactions.

In a process called cellular respiration, chemical energy in food is converted into chemical energy that the cell can use, and stores it in molecules of ATP. ... When the cell needs energy to do work, ATP loses its 3rd phosphate group, releasing energy stored in the bond that the cell can use to do work.
