For G1-phase, one way mistakes during the cell cycle could result in problem is cell doesn’t have a sufficient amount of proteins or other raw materials for the replication of DNA. This condition results in formation of mutated daughter cell.

Further Explanation:

The cell cycle refers to an ordered flow of events which includes cell growth as well as cellular division. This cycle produces two new daughter cells. The cycle starts with interphase in this the cell mature and replicates its own DNA or deoxyribonucleic acid. The interphase begins with:

G1 phase: This is the primary growth phase provide nutrient to the cell. If a cell doesn’t have a sufficient amount of protein or other raw materials for the replication of DNA. It result in formation of daughter cells with damaged or mutated DNA, if not gets repaired.
S phase or synthesis of DNA: During this phase, the replication of DNA takes place. The centrosome is divide and forms mitotic spindle during the mitosis phase. Mistake in this phase will leads to the loss of DNA mutations or integrity.
G2 or second gap: during this phase, the cell mainly replenishes its energy stores as well as synthesizes the proteins which are required for the chromosome manipulation. In this phase error is resolved even in case of unresolved error the cell undergoes division to pass on the error to the daughter cell.

The second stage of a cell cycle is the mitosis or M phase. Chromosomal abnormalities can occur during metaphase of meiosis. It would lead to enuploidy or polyploidy, due to unequal division of chromosomes. Mitotic phase refers to a multiphase process in this the chromosomes are aligned, segregated, and moved into the two new daughter cells which are identical to each other.

Ans.

G1 (or gap 1) is first stage of cell cycle of cell division in eukaryotes. During G1 phase, cell starts to synthesize mRNA (messenger RNA) and protein molecules, which are necessary for DNA replication in next stage and other processes. At the end of G1 stage, cell moves into S-phase of cell cycle, where DNA replication takes place.

Before entering the S-phase, cell's nutritional content and DNA integrity is checked. If cells in G1 show DNA errors or damaged DNA (such as breaks in DNA strands), it will lead to problems as 'it will result into formation of daughter cells with damaged or mutated DNA, if not gets repaired.'

valentinak56 [21]

Answer:

Afferent arteriolar vasoconstriction decreases blood flow into the glomerulus, which causes the glomerular-capillary blood pressure to decrease, leading to a(n) decrease in the net filtration pressure and a resultant decrease in the GFR.

Explanation:

Pretty self-explanatory.

What is the responsibility of the Large Intestines?

Arada [10]

Answer:

Since, we know that the large intestines have so many responsibilities .... The purpose of the intestines is basically to absorb water and including salts from a material, Which means it has not yet been digested as food, and also to get rid of any waste products left over, Also this is very important for the intestines to do this process.

Select ALL the correct answers. Based on these images, what can you say about the tentacles of an octopus and the limbs of a liz

slamgirl [31]

Tentacles of an octopus as well limbs of a lizard are analogous structures.

Analogous structures or organs perform the same function in different organisms that bear no resemblance to each other anatomically. Analogous structures are formed as a result of convergent evolution, i.e. different structures evolving for the similar function and thus having similarity. Tentacles of an octopus as well as limbs of a lizard are used for the similar function, i.e. locomotion in this case.

On the other hand, homologous structures result from divergent evolution. Homologous organs contain a similar basic structure but perform distinct functions in different organisms.
