Answer:
1: the exploitation of biological processes for industrial and other purposes, especially the genetic manipulation of microorganisms for the production of antibiotics, hormones, etc.
2: Genetic engineering, the artificial manipulation, modification, and recombination of DNA or other nucleic acid molecules in order to modify an organism or population of organisms.
3: Genetically Modified Organisms
4: Selective breeding is a form of genetic modification which doesn't involve the addition of any foreign genetic material (DNA) into the organism. Rather, it is the conscious selection for desirable traits.
5:Selective breeding (also called artificial selection) is the process by which humans use animal breeding and plant breeding to selectively develop particular phenotypic traits (characteristics) by choosing which typically animal or plant males and females will sexually reproduce and have offspring together.
6:The use of genetic engineering and the creation of genetically modified crops has resulted in many benefits for the agricultural world. ... By modifying crops so that they are resistant to diseases and insects, less chemical pesticides have to be used to combat diseases and pests.
7:It is known that the main concerns about adverse effects of GM foods on health are the transfer of antibiotic resistance, toxicity and allergenicity. There are two issues from an allergic standpoint.
Answer:
when it's dark, the iris widens and the pupil dilates, or gets bigger, to allow as much light as possible to enter the eye.
Diabetes can affect other organ systems no just the excretory system, organs that are concerned like the kidney or the urinary bladder. This disorder can also cause different complications throughout the vital systems and body processes of the host.
For example, the circulatory system, when there is a great amount of sugar and an imbalance of molecules concentrated in the blood cells, this could affect the nutrition and minerals that the blood cells carry.
In the nervous system, when the brain receives too much glucose it could cause a severe organ failure that can devastatingly cause the host to die.

The answer is Convergence of images behind the Retina
Convex lens converges light to a principal focus. The thickness of the lens determines the focal length (distance between the center of the lens and the principal focal point). Therefore, by evaluating the thickness of the convex lens, farsightedness, (an eye defect of convergence of images behind the retina) can be corrected by enabling images in the eye to form behind the retina.
<u>Answer</u>:
<em>Sodium potassium pump works by following several steps.
</em>
<u>Explanation</u>:
<em>1. Carrier protein binds three molecules of Na+
</em>
<em>2. ATP is split, phosphate bonds to carrier.
</em>
<em>3. Carrier protein changes shape, and deposits Na on the outside of the cell.
</em>
<em>4. Carrier binds two molecules of K
</em>
<em>5. Phosphate is released.
</em>
<em>6. Potassium is released inside the cell
</em>
Sodium -potassium pump is essential to maintain the concentration of sodium and potassium outside and inside the cell respectively.
It is the function of sodium potassium pump to transport sodium out of the cell and potassium inside of the cell against a concentration gradient.
<em>Thus it is an active transport mechanism.
