Answer:
can cause cancer.
Explanation:
The DNA damage is mostly repaired by the repair mechanisms present in cells. If DNA damage is not repaired, it can cause a random change in the genetic material of the organism. These changes in the DNA are permanent and are called mutations. Mutations may be adaptive or harmful. Mutations in a protooncogene leading to overproduction of protein to allow uncontrolled cell division can cause cancer. Similarly, a loss of function in tumor suppressor genes also causes cancer.
According to Mendel's law of dominance,
in such a situation the dominant allele is displayed externally while the recessive allele remains masked i.e, the recessive remains in the genotype along with the dominant allele while in its phenotype, only dominant remains.
Answer: If the F2 occurs in the ratio 9 blue:3 pink:4 white, one gene pair (i.e 2 genes) control the flower color phenotype.
Explanation: This principle is called INCOMPLETE DOMINANCE where one gene (dominant) won't completely override the other (recessive).
Let assume B represents the dominant gene and b represents the reccesive gene. Let also assume that Blue color is dominant over white color. We can assign the genotype as follows;
Homozygous dominant genes BB will produce Blue color
Homozygous recessive genes bb will produce white color
Heterozygous genes Bb will produce pink color.
Therefore, a pair of gene ( 2 genes) will determine the flower color phenotype.
Highly folded membranes allow for more surface area which allows more proteins to help function.
Actually, most things are made up of atoms. Aside from the obvious (atoms themselves, their components and their components relatives), the particles that mediate the fundamental forces (gravitons, photons, gluons, and W and Z bosons, though to be fair only the last two have any actual mass), dark matter, and dark energy are not made up of atoms.
Hope this helps
