The major difference between Gram-positive and Gram-negative bacteria is the presence or absence of an OUTER PLASMA MEMBRANE.
Gram-positive bacteria do not contain an outer plasma membrane, whereas Gram-negative bacteria have a lipid-rich outer plasma membrane.
This outer plasma membrane contains lipopolysaccharide (LPS) in addition to phospholipids and proteins.
Moreover, Gram-positive bacteria are also surrounded by thick layers of peptidoglycan.
In conclusion, the major difference between Gram-positive and Gram-negative bacteria is the presence or absence of an OUTER PLASMA MEMBRANE.

Answer:
Microbiologists use the gram stain technique to identify the gram-positive and gram-negative bacteria on the basis of the composition of their cell wall.
The major difference between the cell wall of gram-positive bacteria and gram-negative bacteria is that in gram-positive bacteria peptidoglycan is the major component which makes gram-positive cell wall whereas in gram-negative bacteria their cell wall has a thick outer layer of Lippo polysaccharide and a thin inner layer of peptidoglycan.
So in gram stain gram-positive cell wall retains the crystal violet because of the thick peptidoglycan layer and appears violet and gram-negative appears pink as it lacks the outer thick peptidoglycan layer.

(this is talking about the periodic table
Answer:
it's really simple, all you need to do is look at the periodic table. for example, group 1A has 1 valence electron. 2A has 2, 3A has 3, and so on.

the scientific name for foxes: Vulpes
internal fertilization
conjugation
pollination
Solution:
An act of fertilization in which genetic information is transferred between cells is called conjugation.
Image result for What is conjugation in science?en.wikipedia.org
Conjugation is the process by which one bacterium transfers genetic material to another through direct contact. During conjugation, one bacterium serves as the donor of the genetic material, and the other serves as the recipient.
This is the required answer.
An act of fertilization in which genetic information is transferred between cells is called conjugation.
Conjugation is the transfer of genetic material between bacterial cells by direct cell-to-cell contact or by a bridge-like connection between two cells.[1] This takes place through pilus
