a person eats one hard-boiled egg and digests the egg fully. during cellular respiration most of the calories in the egg is converted to
During cellular respiration, most of the calories in the hard-boiled egg are converted to ATP (adenosine triphosphate), which is the primary source of energy for cells.
Cellular respiration is the process by which cells break down glucose (and other energy-rich molecules) and convert it into ATP. The energy stored in ATP is then used by the cells to perform various functions, such as maintaining membrane potential, synthesizing proteins, and driving muscle contraction.
In the case of the hard-boiled egg, the calories contained in the egg yolk and egg white are broken down into glucose and other energy-rich molecules by the digestive process. These molecules are then transported into cells, where they undergo cellular respiration and are converted into ATP.
The ATP produced in this process is then used to power the cells, providing the energy necessary for normal cellular function.

of the following ideas postulated by gregor mendel, which one requires at least two genes to be demonstrated?
Out of all the theories advanced by Gregor Mendel as stated above, "Genes assort independently in diploids" is the only one that needs at least two genes to be proven.
A cell with two full sets of chromosomes is said to be diploid. This has twice as many haploid chromosomes as before. A diploid cell's two chromosomal pairs are regarded as homologous chromosome sets. One chromosome from the mother and one from the father make up a homologous chromosomal pair. There are 46 chromosomes in all, divided into 23 pairs of homologous chromosomes in humans. The X and Y homologs in men and the X and X homologs in females are the paired sex chromosomes.A cell that contains two sets of chromosomes is called as the diploid cells. Mendel has stated that genes assort independently in diploids i.eThe allele a gamete received for one gene does not in any way influence the allele received for another gene. Hence at least two genes is needed for its demonstration.
