<span>Parents can pass on chromosomes to their children that are different than their own when the new gene combinations are created by crossing over. The exchange of genetic material between homologous chromosomes is known as crossing over which occurs in meiosis. When homologous chromosomes pair up and exchange different segments of the genetic material. As the result, a new combination of genes will be formed. If there was not crossing over, all genes on a chromosome would be inherited together.</span>
Answer:
Explanation: 1) Individual who is bald but neither parents has a widow's peak: As having a peak is dominant and the individual is bald with parents that doesn't have the trait, the genotype is recessive, in the case ww;
2) Individual has a widow's peak: The individual's genotype can be WW, homozygous for the trait or Ww, heterozygous for the trait, depending on the genotype of the parents;
3) Individual can't roll their tongue: Being able to roll the tongue is a dominant characteristics, so if the individual can't roll their tongue means the genotype is recessive. But, there is little evidence that this trait is dominant or inheritable;
4) Individual has a widow's peak but their mother does not: In this case, the genotype of the individual is heterozygous (Ww), because the mother is recessive (ww) and the offspring has the trait, so the father must have had it;
5) If an individual does not have a widow's peak (ww), which genotype would be impossible? If this individual crosses over with another individual with the same trait, their children will be all recessive for widow's peak (ww), so there is no possibility of an offspring with the trait;
If the initial individual crosses over with an individual with widow's peak, two possiblities can occur:
- If the crossover is with an individual homozygous for the trait (WW): all their children will have widow's peak with genotype Ww. So, the possibility of not having the peak is 0;
- If the crossover is with an individual heterozygous for the trait (Ww), there will be a probability of 25% for the children to have genotype WW, a probability of 50% for the offspring to be heterozygous (Ww) and has the trait and probability of 25% to be recessive (ww) and therefore doesn't have the trait;

Answer:
Deletion and glycosylation.
Explanation:
Proteins is polymers of the alpha amino acids that are directly linked together through the peptide bond. Proteins plays an important role in the metabolic pathways as most enzymes are made of protein.
The same protein can exist in two different size. This might occur due to the deletion of the particular amino acids sequence in one organism and normal in other organisms. The glycosylation of the same protein at different position in the proteins may also leads to the difference in the protein size.
Thus, the correct answer is deletion and glycosylation.
Answer:
1. Both neutron stars and black holes are the corpses of stars that died in explosions known as supernovas. Black holes form when the most massive stars die and neutron stars form when stars not as large die. They both have a very strong gravitational pull, but a black hole's pull is stronger than a neutron star. Neutron stars <u>will turn into</u> black holes if the force of gravity breaks the resistance of electrons.
2. White dwarfs are degenerate, which means they can compress matter. The material in a white dwarf no longer undergoes fusion reactions, so it is supported only by electron degeneracy pressure. This causes it to be extremely dense, saving space and energy.
3. A light year is the distance light travels in a year while an astronomical unit is the average distance between the earth and the sun.
4. A convection zone transfers energy by radiation and conduction.
