What I know is that sickle-cell anemia is when red blood cells are sickle-shaped instead of disc-shaped and can't deliver enough oxygen to the cells in the body.
Answer:
receptor binding
Explanation:
Hormones are able to act specifically on target cells through receptor binding. This process enables target cells to react to a specific hormone only. The cells have hormone receptors within or on their surface which permits the specific hormone to act on it, thereby initiating a series of functions of the particular cell that has the hormone receptor. For example, thyroid receptors respond to thyroid-stimulating hormone.
A developing cell that is totipotential is capable of developing into any type of cell in the organism
Explanation:
Totipotent cells are the specialized cells which are capable of differentiating into many of specialized cells.
The fertilized egg or zygote is the best example of totipotency in human.
Totipotency is able to produce a full organism by differentiating the zygote cells.
Totipotent cells can form placental cells, extraembryonic or placental cells.
After the fertilization the zygote is formed which divides into identical cells that are totipotent and are able to form three germ layers as endoderm, mesoderm and ectoderm. The stages of morula , blastula and trophoblast are formed. After several divisions the cells are specialized to formthe specific tissue and organs.
RNA regulation at various levels of stages play a significant role in totipotency.
Hmmm i think its the third one because men only have 1 x chromosome therefore without the other one if the x chromosome on a men carries a disorder it will show because there is no other chromosome to balance it out and in women the disorder has to show on both X chronosome (and its rarer) for a disorder to appear therefore women having a second X chromosome is effectively a protection
<span>D. Eukaryotic cells have a more complex cellular organization.
Hope this helps!</span>
