Answer:

Explanation:since T- represent tallness

t-dwarf plant

TT- means the plant is homozygous tall i.e the allele T is the same 100% talk

Tt- means the plant is heterozygote tall which implied that though this plant express tallness its still have gene for shortness hidden in its cell and if crossed with a plant that is dwarf some of the offspring will be dwarf.

From the test cross all the gametes are heterozyote - Tt Tt Tt Tt

Answer:

The pressure of a gas increases in a closed container if the volume of the gas decreases. Pressure and volume have inverse relationship which means if one increases the other decreases and vice versa. If pressure increases, volume of a gas decreases because there are a lot of empty spaces present between gas particles which are filled when gas particles come closer to each other due to pressure applied.

If a mutation occurred that increased the number of exons in a sequence of DNA, what impact would this have on the protein forme
erastovalidia [21]

Answer:

See the answer below

Explanation:

<em>An increase in the number of exons in a sequence of DNA would result in another protein with a longer amino acid sequence.</em>

<u>Exons are the coding part of a gene as opposed to introns. After transcription, the non-coding part of the gene - the introns - are removed by splicing and the exons are joined back together. The final RNA that will undergo translation consists of only exons. </u>

The longer the exons in a gene, the more the codons present in the corresponding mRNA from the gene, and the more the number of amino acids that would be translated from the mRNA. A longer amino acid chain would result in a different protein.

Hence, a mutation that causes an increase in the number of exons in a sequence of DNA would result in a different protein with a longer amino acid sequence.

Why do plants store their food?
Ierofanga [76]

Explanation:

Storing the food helps them to use it in winter and survive because there is very little sunlight available and so they photosynthesis less. When they have extra food they store it in their seeds and when the seed grows it gets it's food from the plant until the plant is able to photosynthesis and produce its food.
