Answer:A radical (often, but unnecessarily called a free radical) is an atom or group of atoms that have one or more unpaired electrons. ... A prominent feature of radicals is that they have extremely high chemical reactivity, which explains not only their normal biological activities, but how they inflict damage on cells.

The rate for a recessive allele to decline to half its initial frequency will depend on the presence of selective evolutionary forces and random mating.
<h3>What is recessive allele frequency?</h3>
The recessive allele frequency refers to the initial frequency of a recessive allele in a population, which is masked in heterozygous individuals.
The recessive allele frequency depends on the adaptive fitness of this gene variant, the presence of selective forces and random mating, that facet its rate of change.
In conclusion, the rate for a recessive allele to decline to half its initial frequency will depend on the presence of selective evolutionary forces and random mating.

Answer;
-The above statement is True.
ATP is an unstable, high-energy molecule that provides body cells with a form of energy that is immediately usable.
Explanation;
-ATP is an unstable molecule which hydrolyzes to ADP and inorganic phosphate when it is in equilibrium with water. The high energy of this molecule comes from the two high-energy phosphate bonds. The bonds between phosphate molecules are called phosphoanhydride bonds.
-It only stores small amounts of energy by adding phosphate groups to the ADP molecules and then produces ATP. It can easily release and store the energy by breaking and re-forming the bonds between phosphate groups which is the basic energy source for cells.
Explanation:
Hemoglobin, or haemoglobin, abbreviated Hb or Hgb, is the iron-containing oxygen-transport metalloprotein in the red blood cells of almost all vertebrates as well as the tissues of some invertebrates. Hemoglobin in blood carries oxygen from the lungs or gills to the rest of the body.
