There are several differences between the two, but the biggest distinction between them is that
—————————————————————
eukaryotic cells have a distinct nucleus containing the cell's genetic material, while prokaryotic cells don't have a nucleus and have free-floating genetic material instead.
Answer:
C) is prevented due to growth-inhibiting proteins of oligodendrocytes
Explanation:
Oligodendrocytes are the neuroglial cell and mainly serve to support neurons. These cells also produce a myelin sheath around axons of neurons of the central nervous system. Axons in the CNS display little regrowth or neurogenesis. Inhibition of regeneration is due to several factors such as the absence of a neurolemma and an inhibitory influence of the oligodendrocytes on axon regrowth. For the purpose, the oligodendrocytes produce growth-inhibiting proteins. Axons in the CNS are myelinated by oligodendrocytes and this myelin is one of the inhibiting factors in the regeneration of neurons.
Answer:
Explanation:
Although Mendel's principle of independent assortment states that alleles of different ... Sometimes, alleles of certain genes are inherited together, and they do not ... and it generally describes an inheritance pattern in which two genes located in ... In this case, the ratio of phenotypes observed among the offspring is 9
My answer -
Organisms that reproduce sexually do so via the production of sex cells, also called gametes. These cells
are very different for the male and female of a species. In humans,
male sex cells or spermatozoa (sperm cells), are relatively motile.
Female sex cells, called ova or eggs, are non-motile and much larger in
comparison to the male gamete. When these cells fuse in a process called
fertilization, the resulting cell (zygote) contains a mix of inherited genes from the father and mother. Human sex cells are produced in reproductive system organs called gonads. Gonads produce sex hormones needed for the growth and development of primary and secondary reproductive organs and structures.
