<span>All extremities of the human body, including fingers, hands, arms, toes, feet, legs, ears, and the nose, could be examined by a nurse to confirm a diagnosis of frostbite. As frostbite is a condition of the skin, any exposed area should suffice to confirm the diagnosis.</span>
This is a typical case of a dihybrid cross.
From the phenotype of the offspring, we can conclude that the gene for the red color of the flower and the gene for the axial position of the flower are dominant.
Since we know that the ratio of phenotypes in a dihybrid cross of independently inherited alleles is
9(dominant for both traits)
3(dominant for one trait, recessive for the other)
3(dominant for the second trait, recessive for the other)
1(recessive for both traits)
we can expect 3/16 of the f2 generation to be dominamt for one trait and recessive for the other (red, terminal flowers), or to be precise 190 individuals.
The answer to this question is A
The constant turnover of body tissues requires the <u>chemical energy </u>supplied by carbohydrates, proteins, and lipids.
<h3> What is Chemical energy?</h3>
- The bonds of chemical molecules contain energy.
- Exothermic reactions are those in which chemical energy is released during the reaction, frequently in the form of heat.
- Some of the heat energy needed for a reaction to continue can be stored as chemical energy in newly created bonds.
- The body transforms the chemical energy in food into heat and mechanical energy.
- At a power plant, coal's chemical energy is transformed into electrical energy. Through the process of electrolysis, the chemical energy in a battery can also generate electricity.
