S and M phase
anaphase
-disjunction of two sister chromatids
Answer:
Option B is correct
Explanation:
Given -
"Ability to taste the chemical phenylthiocarbamide" is autosomal dominant while its inability is recessive.
Autosomal dominant means that even if one l
Let the allele for dominant trait i.e "Ability to taste the chemical phenylthiocarbamide" be represented by "T"
and the allele for recessive trait i.e "Inability to taste the chemical phenylthiocarbamide" be represented by "t"
Genotype of a taster woman with a nontaster father is Tt
Genotype of a taster man who in a previous marriage had a nontaster daughter is also Tt
Tt * Tt
TT, Tt, Tt, tt
Therefore probability of being a taster is , and the probability of being a nontaster is
Probability that their first child will be a taster girl is equal to
Probability of being a taster Probability of being a girl
Thus, option B is correct
Answer:
The ability of species of living beings to overproduce offspring
Explanation:
Darwin proposed that species have the ability to produce offspring at a rate that could cause a geometric increase in the population size. This is called biotic potential. The overproduction of offspring causes intraspecific competition for the limited available resources. Darwin reasoned that the overproduction of progeny leads to a struggle for existence between the individuals of a population. He observed that the struggle for existence does not allow the population size of species to grow geometrically.

Solvency, cohesion, adhesion, hydrogen bonding, chemical reactivity, and thermal stability are all important properties of water.Water has the specific cappotential to dissolve many polar and ionic materials. This is vital to all residing matters because, as water travels thru the water cycle, it takes many precious vitamins along side it! Water has excessive warmness capacity.
Water's enormous functionality to dissolve a lot of molecules has earned it the designation of “regular solvent,” and it's far this cap-potential that makes water such a useful life-maintaining force. On a organic level, water's position as a solvent allows cells shipping and use materials like oxygen or vitamins.
A water molecule has 3 atoms: hydrogen (H) atoms and one oxygen (O) atom. That's why water is every so often known as H2O. A unmarried drop of water incorporates billions of water molecules.
