28 find that the cell spends in prophase (number of cells in prophase divided by the total # of cells (36) multiplied by 100)
Answer:
See below.
Explanation:
A star's energy comes from the combining of light elements into heavier elements in a process known as fusion, or "nuclear burning". It is generally believed that most of the elements in the universe heavier than helium are created, or synthesized, in stars when lighter nuclei fuse to make heavier nuclei. The process is called nucleosynthesis.
Our Sun is currently burning, or fusing, hydrogen to helium. This is the process that occurs during most of a star's lifetime. After the hydrogen in the star's core is exhausted, the star can burn helium to form progressively heavier elements, carbon and oxygen and so on, until iron and nickel are formed. Up to this point the process releases energy. <u>The formation of elements heavier than iron and nickel requires the input of energy. </u>Supernova explosions result when the cores of massive stars have exhausted their fuel supplies and burned everything into iron and nickel. The nuclei with mass heavier than nickel are thought to be formed during these explosions.
<span>The muscle is a soft tissue found in most animals. The cells in the
muscle contain protein that produces a contraction that changes both the length
and shape of the cell. They are responsible for the movement it produces in the
human body. There are three types of muscle cell: skeletal, cardiac and smooth
muscle. Cardiac muscle contains excess amounts of mitochondria and myoglobin. The
myoglobin is responsible for the red color of the muscle. The answer is letter
B.</span>
Answer:
Option A
Explanation:
Xeroderma pigmentosum arises as a result of the cell being unable to correct lesions induced by UV. This can be as a result of mutations in the enzymes which include XP A-E needed for correction of the lesions. Failure to correct these lesions leads to their accumulation and then damage to the cell.
