I think it’s 2 because the cell goes through 4 steps
That is true. <span>The thymus functions strictly in maturation of t cells.</span>
If you hold the cut higher than your heart it will stop bleeding but it will also start to cloct up and thats a good thing cause it stops bleeding
Answer:
D. If all of the offspring are short-tailed, the unknown individual is the homozygous dominant genotype.
Explanation:
The short tail phenotype is completely dominant over the long tail phenotype. When a short tailed salamander with unknown genotype is crossed with a homozygous recessive long tailed salamander, the cross is called testcross. Lets assume that the allele "S" gives "short tail" phenotype while the allele "s" gives "long tail" phenotype.
If the "short tailed salamander" with unknown genotype is homozygous dominant (SS), the process of the testcross will express only dominant trait (cross 1). On the other hand, if the "short tailed salamander" with unknown genotype is heterozygous dominant (Ss), segregation of alleles during gamete formation would form two types of gametes (cross 2). The 50% progeny would express the "long tail" phenotype while rest 50% will express the "short tail" phenotype.
Answer:
<h2>
The speed of action potential propagation get slower down</h2>
Explanation:
Myelination is the process of generating myelin in neurons. In CNS, oligodendrocyte make the myelin sheath.
The main function of myelin is to increase the speed of electrical impulses along the myelinated fiber.
Myelinated fibers lack voltage-gated sodium channels along the myelinated internodes, having them only at the nodes of Ranvier though which the molecules moves.
Demyelination is the loss of the myelin sheath, result due to some neurodegenerative autoimmune diseases, resulting in the decrease of the speed of action potential propagation.
