Why are diploid cells abbreviated 2n and haploid cells abbreviated 1n​

Biology
1 answer:
Ganezh [65]3 years ago
4 0

Answer:

Diploid cells abbreviated 2n and haploid cells abbreviated 1n​ because 'n' represents number of chromosome present in the cell. In haploid cells the number of chromosome is half in number while in diploid cells the number of chromosome is double so that's why haploid is abbreviated as 1n and diploid is abbreviated as 2n.

Diploid cells are present in body cells while haploid cells are found in sex cells.

HELP!
Kryger [21]

Answer:

discovered moons around Jupiter and phases of Venus.

Explanation:

This is because Galileo was a scientist that discovered some proofs to back heliocentric theory.

They would not orbit around Jupiter if the Earth was at tye center of the system. Venus is very close to the sun and it won't go through phases of the Earth is at the system's center.

ATP is synthesized by substrate-level phosphorylation during which of the following?
pav-90 [236]

Answer:

C. only glycolysis and the Krebs cycle

Explanation:

Conversion of 1,3-bisphosphoglycerate into 3-phosphoglycerate and conversion of phosphoenolpyruvate into pyruvate during glycolysis obtains a total of 4 ATP molecules per glucose (2 from each reaction). Here, ATP formation occurs by the transfer of the phosphoryl group from a substrate such as 1,3-bisphosphoglycerate. Therefore, it is called a substrate-level phosphorylation.  

Similarly, oxidative decarboxylation of alpha-ketoglutarate into succinyl CoA and conversion of succinyl CoA into succinate forms 2 ATP molecules per glucose during Kreb's cycle. Here, the energy for ATP synthesis is provided by oxidative decarboxylation of a substrate. Therefore, it is also substrate-level phosphorylation.

When a microbe that is not part of the normal biota enters the body, it is likely to first encounter which type of host defense?
olasank [31]

When a microbe that is not part of the normal biota enters the body, it is likely to first encounter first line of host defense.

The term "normal microbiota" describes the microorganisms that are present in every human's conjunctiva, oral mucosa, skin's surface and deeper layers, saliva, and gastrointestinal tracts. The host employs a number of defences to defend against infection.

Mucus, which has a variety of normal microbiota that compete with and may even destroy invasive bacteria and virae, is one of the body's first lines of defence.Once a virus or bacteria penetrates the skin and mucosa, the host may experience changes that lessen the invader's power. A fever is one instance of such a shift.

Therefore, When a microbe that is not part of the normal biota enters the body, it is likely to first encounter first line of host defense.
