How do genetics (genetic predisposition) and the environment work together to cause substance abuse in individuals? What is the

likely role of epigenetics in this process?
Biology

vampirchik [111]3 years ago

Answer: The drug abuse is influenced by the environment and exerts influence on the gene expressions.

Explanation:

The genetic make up of the person is decides, which genes will be expressed and develop a trait in an individual. But this genetic expression can be influenced by the environmental factors like food, exposure to sunlight, and others. This study which relate environment with the genetic make up is called epigenetics. No person is drug addict by birth but the consumption of drug can influence the genetic make up and traits in a abuser. So here, the environment is influencing the genetic basis of a abuser.

What three (3) factors determine the reactivity of elements? Explain and give examples of each.
Ivenika [448]

Three factors that determine the reactivity of elements are the valence electrons are the electrons in the outermost electron shell of an atom. The number of electrons in an atom's outermost valence shell governs its bonding behaviour. That is why in periodic table the elements were put together according to their numbers of valence electrons.

METALS

The most reactive kind of metallic element is a metal from Group 1 sodium or potassium.

An atom in Group 1 has only one valence electron.

NON-METALS

A nonmetal tends to attract another valence electrons to attain a full valence shell.

Which statement about sexual and asexual reproduction is true? *
weqwewe [10]

Answer:

The answer is A. There is more genetic variation in organisms that reproduce sexually than those that reproduce asexually.

Explanation:

This is because offspring with two parents can get genetics from both family's which means there is a chance for many different types of characteristics.

If an offspring only has one parent however, the offspring will only get those genetics from the parent which means there are not many possibilities for offspring to look or act different then their parent.

Hope this helps! Have a good day! or don't...it's up to you- <3

Theoretically, how might researchers disrupt signal transduction pathways as possible treatments for cancer?
ivann1987 [24]

Answer:

d. disrupt the function of protein kinases involved in cell cycle regulation.

Explanation:

Protein kinases which are useful in cell cycles have major roles in the formation of tumors. So many of these protein kinases go through mutations. Cell cycles would be unable to be stoped and tumor would keep increasing.

A lot of receptors are G protein coupled. So it is going to be really helpful to alter and make G protein receptors to be inactive. Most if these kinases go through means of phosphorylation and dephosphorylation. Targeting these would cause disruption in signal transduction in cells with cancer
