The part of the root that contains transport tubes is the root hair. The primary role of the root hair is to absorb water and nutrients from the soil. They are hair-like and tubular in structure and are sometimes rarely visible by the naked eye.
Answer:
B) 1/2 X 1/2 = 1/4
Explanation:
It happens when both the parents are heterozygous for the trait. The cross related to this result is shown as under:
Father Mother
Bb x Bb
/ \ / \
Gametes: B b B b
| | | |
Probability: 1/2 1/2 1/2 1/2
The probability of formation of 'b' gamete from father is 1/2 because there are only two gametes 'B' and 'b' and out of these two one will be assorted as 'B' and another one as 'b' and from mother also the probability of formation of 'b' gamete is 1/2.
Now the assortment of gametes with each other is an independent event i.e. any gamete from father can fuse with any gamete of mother so the overall probability of formation of 'bb' genotype will be 1/2 x 1/2 = 1/4.
Answer: I can not answer the question until you add the answer choices, but as soon as you do I will answer your question.

Answer:
B. Interneurons
Explanation:
The basic unit of the central nervous system is the neuron or the nerve cells. Billions of neurons allow the different parts of the body to communicate with each other via the brain and the spinal cord. A fatty material called myelin coats nerve cells to insulate them and to allow nerves to communicate quickly.
