Answer:
TACGTACGTTAC (so the second one)
Epigenetics is the study of how DNA methylation and alterations to chromosomal proteins affect a gene or group of genes express themselves. For changes in a gene's expression, both of these are need.
In a biological process called DNA methylation, methyl groups are added to the DNA molecule. A DNA segment's activity can be altered by methylation without the sequence changing. DNA methylation usually inhibits transcription of genes when it occurs in a gene promoter.
Epigenetics literally translates to "along with changes in genetic sequence." Any procedure that modifies gene activity without altering DNA sequence and results in modifications that can be passed on to daughter cells is now included in the term. Is called Epigenetics.

Answer:
the population is polymorphic.
Explanation:
Polymorphism is the discontinuous genetic variation that leads to the production of varying unique kinds or forms of individuals within the population of an individual species.
Take for instance, allelic polymorphism is seen in the presence of multiple alleles that is produced within the members of an individual species as in peppered moths, human blood groups, and two-spotted ladybugs.
We have different causes of polymorphism: polymorphism can be sustained by an equity among variation developed by new mutations and natural selection. Genetic variation might be due to frequency-dependent selection.
That is correct, a good description of the HYPODERMIS. Hence many syringes get the name "hypodermic" needles.
Answer:
Hypothalamus of human body system interact to perform temperature regulation along with nervous system and endocrine system.
Explanation:
Hypothamus is an important part of our lower brain that play a significant role in regulation of body temperature.
Hypothalamus works with nervous system along with the other parts of our body such as blood vessels,skin and sweat gland to maintain temperature homeostasis of human body.
When our body temperature rises at that time hypothalamus slows down the rate of metabolism of our body to restrict further increase in our body temperature and also dilates the blood vessels present beneath the skin so that body can liberate heat to the environment.
on the other hand when the body temperature decreases at that time hypothalamus increases the metabolic rate of our body to increase the body temperature and also the constrict the blood vessels present under the skin.
