The myelin sheath is the protective layer, which is present in the outer layer of the neural cells. This myelin sheath prevents the loss of electrical impulses, which are being conducted in the neurons. This also act as an insulator between neuron and its external environment.

This layer is mainly made up of the protein and fatty substance. The degeneration of the myelin sheath result in many neurological disorders.


Hence, the correct answer is myelin sheath.

<h3>What are plate tectonic boundaries?</h3>

A plate boundary is a three-dimensional surface where the velocity (speed or direction) of one lithospheric plate relative to the adjacent lithospheric plate changes significantly.

Consider the phylogenetic tree. Which two organisms are most closely related, based on the tree above?
Aleksandr [31]
Answer: dinosaurs and birds
Plentiful collection of f<span>ossils of early birds and their most immediate predecessors has settled the century-old controversy about the origin of birds. Birds are now safely declared to evolve from a group of dinosaurs known as maniraptoran theropods. Birds have similar shape of the bones as a variety of maniraptorans have.  A host of fossils have shown also that the maniraptorans lay looked alike eggs as that of birds and they resemble the birds in the way they laid their eggs also. Those reasons prove that they are most closely related.</span><span>

In a cross between two heterozygous tall and purple flowers (TtPp x TtPp), what would the
Goryan [66]

Answer:

9:3:3:1

Explanation:

This question involves two different genes coding for height and flower color respectively. The first gene posseses allele T (dominant) and t (recessive) while the second gene possesses allele P (dominant) and p (recessive).

According to this question, two heterozygous tall and purple flowers are crossed i.e. (TtPp x TtPp). Each parent will produce the following gametes combination:

TtPp - TP, Tp, tP, tp

Using these gametes in a punnet square, the following proportion of offsprings will be produced:

T_P_ (tall, purple) = 9

T_pp (tall, white) = 3

ttP_ (short, purple) = 3

ttpp (short, white) = 1

Hence, the ratio of this cross is 9:3:3:1
