Answer:
Crush the limestone... it would give more area for the acid to react
Explanation:
when the limestone is crushed, irt will expose more surface area to the acid making the reaction go quicker.
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.
Zwitterion
Zwitterion also known as dipolar
ion refers to a substance that has at least one positive and one negative
electrical charge at different locations and the net charge of the entire
molecule is zero. Examples of zwitterions are amino acids.
The answer should be a. receptor sites in the surface of the cell
hope this helps :)
