Give me the whole question!! im really good at science sis:)
Answer:
Tall and short trees are genotypically homozygous for their trait
Intermediated trees are genotypically heterozygous for their trait.
Explanation:
Let the allele representing tall trait be "T"
and the allele representing short trait be "t"
It is given that when a tall and short plant is fused all the offspring are of intermediate height.
This simply means that the both the plants are genotypically heterozygous for their traits
Genotype for tall tree - TT
Genotype for short tree - tt
TT * tt
Tt, Tt, Tt, Tt
All the offspring are of intermediate height.
Now these two plants of intermediate height are crossed
Tt * Tt
TT, Tt, Tt, tt
Out of four plants two are of intermediate height, one is of tall heingth and the remainig one is of short height
<em>C. Binding to the operator.</em>
Explanation:
When the repressor starts binding to the operator, it can not transcribe, or make mRNA. This makes it so the RNA polymerase can't go onto the promoter and bind to it, which is a crucial part in making mRNA. The operator functions by making sure the certain DNA gets made, so it is very important. The lac repressor will turn off the expression of the lac genes by binding to the operator.
Which of these is involved in asexual reproduction in a plant?
C. Bulb
Answer:
plants protect soil from being eroded by locking the soil in place.
Explanation:
dirt can rock can not move when there is plant life in the way. refer to the dustbowl
