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?
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.

PLEASE I NEED HELP Explain how the process of mitosis is essential to the regeneration of tissue using stem cells
Answer:
Mitosis is essential to the regeneration of tissue because during Mitosis, cells replicate to create a daughter cell that is the exact copy of the parent cell.
Explanation:
The reason this is so important is because stem cells can develop into nearly any cell type. Mitosis allows these cells to replicate the exact cell type needed (in this case, tissue), and create a daughter cell that has the same exact components and characteristics of the parent cell.

If the Universe was born at the Big Bang, what existed before then
Explanation:
In the beginning, there was an infinitely dense, tiny ball of matter. Then, it all went bang, giving rise to the atoms, molecules, stars and galaxies we see today.
Or at least, that's what we've been told by physicists for the past several decades.
But new theoretical physics research has recently revealed a possible window into the very early universe, showing that it may not be "very early" after all. Instead it may be just the latest iteration of a bang-bounce cycle that has been going on for … well, at least once, and possibly forever.
Of course, before physicists decide to toss out the Big Bang in favor of a bang-bounce cycle, these theoretical predictions will need to survive an onslaught of observation tests.
The initial singularity is a singularity predicted by some models of the Big Bang theory to have existed before the Big Bang and thought to have contained all the energy and spacetime of the Universe.

What two simple machines is a stapler made up of?
1. wheel and axle and lever
2. lever and pulley
3. wedge and screw
4. wedge and lever
Answer:
4. wedge and lever
Explanation:
Simple machines are mechanical devices which make our work easier. Examples are : lever, wedge, wheel and axel, pulley, screw and an incline plane.
A stapler is a made up of a level which is the handle part and a wedge which are the staples.
A pulley is a simple machine that has one or more wheels connected with a rope in a loop to make lifting of loads easier because it changes the direction of force applied/pull thus multiplying the force applied. A stapler does not have the wheel and the rope thus answer choice 1 and 2 are incorrect.
A screw is a simple machine that applies torque on a shaft to produce a large axial force on the load. It utilizes the conversion of rotational motion to a linear motion and a torque to a linear force. A stapler mechanism does not involve rotational motion or rotational force, hence answer option 3 is incorrect.
A stapler is made up of a combination of two simple machines: the wedge and the lever. The correct option is 4.
A stapler utilizes a wedge to perform its primary function. The wedge is the part of the stapler that drives the staple through the paper. It has a sharp, triangular shape that allows it to exert a large amount of force over a small area, making it easier to pierce through the materials.
The stapler also incorporates a lever mechanism. The lever is the long arm of the stapler that is pushed down to drive the wedge and staple into the paper.
By applying force at one end of the lever, a mechanical advantage is gained, allowing the user to apply a smaller force to produce a greater force output at the other end, making it easier to staple multiple sheets of paper together.
Therefore, The correct option is 4.

While looking at a cell under a microscope, a scientist is able to see a biological molecule. This molecule is a nucleic acid with a ladder structure and contains the nitrogenous bases adenine, thymine, cytosine, and guanine. Based on this information, what conclusion can the scientist draw regarding this nucleic acid?
Answer:
Based on the information , the scientist concluded that the regarding nucleic acid is DNA (Deoxyribonucleic Acid) .The structure of DNA is attached below -:
Explanation:
PROPERTIES OF DNA -
In humans and almost all other species, DNA, or deoxyribonucleic acid, is an inherited substance. Almost every cell in the body of an individual has the same DNA. The DNA information is stored as a code consisting of four chemical bases: adenine (A), cytosine ( C), guanine ( G) and thymine ( T). In order to form units called base pairs, DNA bases pair up with each other, A with T and C with G. A sugar molecule and a phosphate molecule are both affixed to each base. Together, a nucleotide is called a base, sugar , and phosphate. Two long strands are arranged with nucleotides that form a spiral called a double helix. The double helix structure is much like a ladder, with the base pairs forming the rungs of the ladder and the molecules of sugar and phosphate forming the vertical sidepieces of the ladder.An significant DNA property is that it can duplicate itself or create copies of it. In the double helix, each strand of DNA will serve as a template for duplicating the sequence of bases. As each new cell requires to have an exact copy of the DNA present in the old cell, this is important as cells divide.Hence, the structure identified and conclude by the scientist is DNA (deoxyribonucleic acid). Thus, the structure of DNA is attached below.
Answer:
✓ The nucleic acid is DNA and would be found in the cell's nucleus
