Answer: The atom of carbon is able to form macromolecules because it has only four electrons in its outer shell. This is the reason why it can bond with four other carbon atoms. The bonds that it forms with other carbon molecules are very stable.
Explanation: I did my research and i also took Science class. :)
Hope this Helps :).
Stem cells arise from the inner mass of the cell
Signalling factors trigger differentiation in stem cells
Genes that lead to the production of undifferentiated blood cells are activated
Signalling factors cause undifferentiated blood cells to produce red blood cells
Explanation:
Red blood cells are formed in the bone marrow. The precursor to the RBC is stem cell which is undifferentiated and pluripotent. The stem cell gets differentiated to form immature RBCs. Immature RBC then gets divided and becomes mature. Stem cell giving rise to RBC is called Haemoctytoblast. The process of erythropoiesis takes 2 days to form new red blood cells
<span>The </span>process<span> in which </span>autotrophs use<span> chemical energy to </span>produce carbohydrates<span> is called chemosynthesis.</span>
Damage in the bone marrow, called as aplastic anemia leads to lower production of both red and white blood cells, causing oxysgen starvation and infection.
Platelets are also reduced.
The correct answer is option c
Ethical concern is related to the concerns that is related to the sentiments of the people. They keep on opposing the experiments and tests that is done on the animals for the welfare of human beings.
They believe that people should not intentionally manipulate the genes of the organism in the lab for the welfare of the human beings.
