olya-2409 [2.1K]
Multiple sclerosis develops when  nerve cells in the brain and spinal cord lose the insulating mylien sheaths that surround them.This can happen anywhere in the CNS and is random.
Symptoms are Muscle weakness, loss of sensory input from the skin and other areas, poor vision and mental problems due to the loss of the protective mylien the neurons stop conducting the impulses and hence there is a loss of functions controlled by the areas of the CNS concerned.
Hope this helps! :)

melamori03 [73]
Q1. The answer is egg.

The fertilisation is a fusion of two gamete cells which results in the formation of the zygote. Sperms and eggs are gamete cells, male and female, respectively. After a sperm and an egg fuse, i.e. the fertilisation takes place, a zygote is created and then begins a development of an embryo.


Q31. The answer is 100% chance

Alleles:
T - the dominant allele for the tongue rolling
t - the recessive allele

Genotypes and phenotypes:
TT - people able to roll tongue 
Tt - people able to roll tongue
tt - people not able to roll tongue

<span>The mother’s genotype is TT and the father’s genotype is TT. The offspring will get T allele from the mother and T allele from the father:
Parents:            TT        x         TT
Offspring:     TT      TT      TT         TT

So, all of the offspring will have genotype TT and will be able to roll their tongues.
 

Q32. The answer is codominant.

A codominance is a pattern of inheritance in which both alleles of a gene are expressed. So, there are no dominant and recessive alleles and both will affect the phenotype. For example, plants with alleles for both red and white flowers will have flowers that are both red and white.</span>
