A species is a group of organisms capable of mating and producing offspring, and speciation is the process of forming a new spec

ies.
One way a new species may form is by geographic isolation. This occurs when members of a population are physically separated, for example, by a river, or a desert.

After the separation the two populations, responding to different conditions, will adapt differently, and so their evolutionary paths will...

Variation in dna sequences are useful for building a tree of life because __________.

Genetic variation is the changes that occur in the genome of an organisms to help an organism adapt well to the environment, however, they might also be disadvantageous. The variation in DNA sequences are useful in building a tree of life because DNA sequences are similar in closely related organisms and less similar in less closely related organisms.

Wewaii [24]

Answer:

G-banding or Giemsa banding is a technique used to study the chromosomes by staining then at condensed stage. The visible karyotype can be used by this technique. The genetic diseases can be easily identified by this G banding technique.

The base composition of the genes (nucleotide) are stained by the dye known as Giemsa stain. The nitrogenous base adenine and thymine of the heterochromatic region of chromosome stained darkly in this technique. The darkly stained area is generally gene poor area.

Can someone send me their table for 3.13 meaning of mitosis assignment plz
Firlakuza [10]

Mitosis, a procedure of cell duplication, or multiplication, amid which one cell offers ascend to two hereditarily indistinguishable girl cells. Carefully connected, the term mitosis is utilized to depict the duplication and dissemination of chromosomes, the structures that convey the hereditary data.

A concise treatment of mitosis pursues. For a full treatment, see development: In cells; cell: Mitosis and cytokinesis.

Preceding the beginning of mitosis, the chromosomes have imitated and the proteins that will frame the mitotic axle have been incorporated. Mitosis starts at prophase with the thickening and curling of the chromosomes. The nucleolus, an adjusted structure, shrivels and vanishes. The finish of prophase is set apart by the start of the association of a gathering of strands to frame a shaft and the breaking down of the atomic layer.

The chromosomes, every one of which is a twofold structure comprising of copy chromatids, line up along the midline of the cell at metaphase. In anaphase every chromatid pair isolates into two indistinguishable chromosomes that are destroyed to inverse closures of the cell by the shaft strands. Amid telophase, the chromosomes start to decondense, the axle separates, and the atomic films and nucleoli re-structure. The cytoplasm of the mother cell partitions to frame two girl cells, each containing indistinguishable number and sort of chromosomes from the mother cell. The stage, or stage, after the consummation of mitosis is called interphase.

P.S. You're a mean person. You ought to pursue different people groups bearing and don't simply answers something for focuses. Fortunately, I revealed you and your answers got delted and afterward erased the 50 points that you escaped your focuses. Try not to do that or else no one's going to like you. Bye....
