After completing meiosis II, human sex cells have a total of _____ chromosomes
vodomira [7]

Ans.

Meiosis involves a type of cell division in sexually reproducing organisms that results in formation of four daughter cells from a single parent cell, having half of the genetic material as in parent cell. Meiosis is divided into meiosis I and meiosis II.

In gamete forming cells of humans are diploid cells and have 23 pairs of chromosomes (or 46 chromosomes). Each gamete forming mother cell undergoes meiotic division to form haploid daughter cells or gametes, each with 23 chromosomes.

Thus, the correct answer is 'twenty-three' as there are 23 chromosomes present in human sex cells at the end of meiosis II.

why do all organisms take in matter and rearrange atoms through chemical reactions to form molecules essential for life?
Tom [10]
Cause living things can not directly use most of matter which they found in nature. For example carbon, all organism use carbon in complex structure, that is in compound or macromolecule(glucose,fructose,amino acid). we can not directly earn ATP from C which we found in soil/other sources.

Which vessels are most intimate with the nephron loop and serve as a point to collect ions and water back into the blood?
MArishka [77]
The renal tubule would be the vessel within the nephron loops that functions to collect ions and water back into the blood. In addition, these vessels are the one responsible for emptying the collecting duct and reabsorbs salts present in the bloodstream and disperses it back to the blood.

Reika [66]

Answer:

The correct answer is <em>A. real-time PCR can measure the amount of DNA amplified as the reaction proceeds, while standard PCR cannot.</em>

Explanation:

PCR (Polymerase Chain Reaction) is a molecular biology technique. Conventional PCR and real-time PCR are diferent types of PCR, and are both used to exponentially amplify DNA molecules. In both types, a polimerase enzyme is employed to sinthesize DNA copies. The main difference is that conventional PCR is qualitative whereas real-time PCR is quantitative. So, real-time PCR permits not only to detect and amplify DNA but also permits to perform a quantification of the target DNA. This is accomplished by measuring a fluorescence signal - which is directly the amount of DNA amplified- during the course of the reaction.
