Normal cells in the body follow an orderly path of growth, division, and death. Programmed cell death is called apoptosis, and when this process breaks down, cancer begins to form.
Hey there! :D
When we are talking about gametes, we can use a punnet square, or in this case, common knowledge. If two of the alleles for one phenotype are the same, we can infer there will only be two variations of the genotype. (because there are two dominant SS genes) We already know that "D" must be the answer. Firstly, there will be one allele for each gene, so there will always be an "S" and a "T" no "SS" or "tt" (when talking about gametes). That leaves us with B and D but there is no recessive "s" in the original genotype, so the answer must be "D".
I hope this helps!

Earth's mantle plays an important role in the evolution of the crust and provides the thermal and mechanical driving forces for plate tectonics. Heat liberated by the core is transferred into the mantle where most of it (> 90%) is convected through the mantle to the base of the lithosphere.
Answer:
chemical reaction:-
12H20 + 6CO2 + light =====> C6H12O6 + 6H2O + 6O2
the above reaction shows that if we combine water,carbon dioxide and sunlight ,the resultant products will be glucose ,water and oxygen .
The plant converts the carbon dioxide into energy and oxygen by different steps that include
- absorption of light
- conversion of NADP into NADPH+
- conversion of ADP into ATP
- formation of carbohydrates from CO2 !
Answer:
O silicon (Si)
Explanation:
-Valence electrons are electrons of the outermost shell which can participate in chemical bonding. ... -As in silicon, four electrons are present in the outermost shell, so silicon has Four valence electrons.
