Answer:
The correct answer is: Actinobacteria
Explanation:
Actinobacteria is a phylum of the Gram-positive aquatic or terrestrial bacteria that have high concentrations of guanine and cytosine in their DNA.
These bacteria are economically important to the human beings as they produce bioactive metabolites used in producing medicines and are also responsible for the <u>decomposition of organic matter of dead organisms in the soil.</u>
<u>Therefore, Actinobacteria will be the best bacteria to be used in the laboratory.</u>
Data given
Number of electron = 108
Number of neutron = 158
Required
Mass number=?
Solution
As we know that mass number = No of proton + No of neutron
In any neutral atom the number of proton is always equal to number of electron
So number of proton will be = 108
However the atom has +1 charge which means that one proton is less than no of electron so proton number is 107.
Put values in above formula, we will get
Mass number= 107+108
= 215 Mass number
If your cell did not produce proteins enzymes would not be available to speed up reactions throughout your body, and they would also not be available to make the many organelles made with proteins such as microtubules which would cause many other problems within the cell.

Answer:
Fertilization
Explanation:
Egg and sperm are cells known as gametes produced by the GAMETOPHYTE of a sexually-reproducing organism via meiosis. Since egg and sperm cells are produced through meiotic division, their chromosomal number is reduced by half of the parental organism. Hence, sperms and eggs are haploid cells (n) produced by a diploid organism (2n).
Sperm is the male gamete while egg is the female gamete. These two haploid gametes fuse in a process called FERTILIZATION, to produce a diploid ZYGOTE that eventually grows into the diploid structure of the organism called SPOROPHYTE. This system of reproduction called ALTERNATION OF GENERATIONS is used by lower and higher plants.
A. Wheat, corn, soybeans, and cabbage are the main four plants responsible for providing food to people in the world.
