what is the effect of telomere caps on cancer cells?
The telomere caps help to maintain genome integrity. In consequence, these repetitive sequences are fundamental to avoid the generation of cancer cells.
Cancer cells are a type of cells that proliferates in an uncontrolled manner, which is generally associated with mutations in the genome capable of altering normal gene expression patterns.
Telomere caps are repeated nucleotide sequences found at the end of chromosomes, which help to maintain genome integrity.
The elimination of these repetitive sequences (telomere caps) due to successive cell divisions triggers chromosomal (genome) instability and thus contributes to the emergence of genomic rearrangements that may lead to carcinogenesis.

why do heart cells have a higher percentage of mitochondria than liver and pituitary gland cells?
Answer:
This is because the heart requires large amounts of energy in order to pump blood to the rest of the body. The mitochondria produces ATP for energy, thus heart cells contain a higher percentage of mitochondria for energy to pump blood.
The heart cells have a higher percentage of mitochondria than liver and pituitary gland cells because the heart requires large amounts of energy in order to pump blood to the rest of the body. The mitochondria produces ATP for energy, thus heart cells contain a higher percentage of mitochondria for energy to pump blood.
What is the role of mitochondria in producing energy?The role of Mitochondria in producing energy are in charge of producing energy as ATP. The heart muscle has the highest energetical requirements. Several mitochondria compose these muscle cells because too much energy is needed to pump blood constantly.
Mitochondria are known as the one of the biggest organelles in the cell. They are semi-autonomous organelles surrounded by a double membrane that reproduce by binary fission and contain their own DNA, RNA, and ribosomes. Mitochondria are in charge of aerobic cell respiration, the process by which cells use organic compounds and turn them into energy.
Therefore, The mitochondria produces ATP for energy, thus heart cells contain a higher percentage of mitochondria for energy to pump blood.

Hope this helps you XD ✌️Carry on learning !!Can sunlight change the distribution of traits in a population?(1 point)
No, because the environment can only change behaviors.
Yes, because the environment is the only factor that can change traits.
Yes, because the environment can factor into the distribution of traits.
No, because the environment can only change traits in individual organisms.
A number of factors including environmental factors (for example sunlight) can also play a role in how the traits in a particular population is distributed.
Sunlight can change the distribution of traits in a population because the environment can factor into the distribution of traits.
The distribution of traits is changed when factors in the environment change/evolve and influence natural selection. These environmental factors including sunlight alter the selection of traits passed to generations and can have an effect on the distribution of the traits on Earth.Learn more about environmental factors: https://brainly.com/question/3638961
The sunlight can be a factor for the distribution of traits in a population. Option C is correct.
Natural selection:
It is phenomenon in the evolution in which a population of species in distributed in the habitat or evolve by the certain traits that fits in the nature.
For example-
A population of a species have two types of traits,
1. Individuals that can bear the intense light.
2. Individuals that can not bear the intense light, prefer low light.
After several generation the whole population will divide in the groups according to their ability to bear the intensity of light.
It can also result in the new species that only wake up at night to avoid the sun.
Therefore, the sunlight can be a factor for the distribution of traits in a population.
