The answer for that is because they reproduce asexually like through binary fission
I’m pretty sure they’re cirrus clouds. ☁️
Telomeres are regions that make up the end of each chromosome. These 5 nucleotide repeats help preserve the integrity of the DNA during replication. However, in each division, the telomeres shrink. Some scientists have seen in this mechanism a biological clock governing the aging of cells. Until now no one has shown a link between the two phenomena.
The size of the telomeres (the number of repetitions) varies from one individual to another at birth. At each replication cycle, the chromosomes shorten. This is because the enzyme responsible for its replication cannot copy the end of the chromosomes. It is estimated that 100 nucleotides decrease the size of telomeres by division in humans. When the telomeres become too short and before the genes are affected, or the chromosomes merge with each other, the cells stop their division and enter into senescence.
A single enzyme is able to extend the telomeres, telomerase. This enzyme is not active in somatic cells. However, there are somatic cells that are immortal, these are the cancer cells. They have lost control of their cell cycle and can divide indefinitely. This ability to multiply without limit is accompanied by the activation of telomerase.
Answer;
-Saturated fats
Explanation;
-Cholesterol is transported in the blood by different carriers. The relative amounts of cholesterol transported by each carrier can affect one’s risk for heart disease. The two major blood cholesterol carriers are LDL (low density lipoprotein) and HDL (high density lipoprotein).
-LDL cholesterol is known as “bad” blood cholesterol, and functions to deliver cholesterol to cells throughout the body and can be deposited as “plaque” on artery walls.
-Dietary fat, especially saturated and trans fats, may raise blood levels of total and LDL cholesterol. High total blood cholesterol levels and LDL cholesterol levels increase risk of heart disease.
