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.
Answer:
B. It is a nucleic acid
F. It allows parents and their young to have similar characteristics.
Explanation:
The genetic material refers to the molecule which acts as the coding material of the organism as it contains the code of protein and thus controls the basic function of the life.
The genetic material of the organism belongs to a class of molecule called nucleic acid as they are found in the nucleus of the cell. There are two types of nucleic acids called DNA and RNA.
The genetic material gets passed from the parents to the offspring through reproduction therefore the offsprings develop the same character as of their parents.
Thus, the selected options are correct.
Answer:
Muscle cramps are caused by the inability of myosin fibers to break free from the actin filaments during contraction, resulting in a prolonged contraction. A lack of ATP would obviously produce cramping, as myosin requires ATP to become free from actin.
