Salutations!
A meander that has been cut off from the river is called oxbow lake. I will now give an explanation on how an oxbow lake is formed.
An oxbow lake is a narrow U-shaped lake near a river. Its a meander that got cut off.
As erosion, continues, the neck of the meander is worn away. It gets narrower and narrower. Then, during flooding, the river takes a shortcut - straight across the neck. Soon the loop of the meander gets sealed off. It turns into an oxbow lake. In time, the lake will get covered with weeds, and fill with soil, and disappear.
Hope I helped (:
Have a great day!
Answer:
8 chromosomes
Explanation:
Mitosis is the process whereby a cell divides into two identical copies of itself. This genetical identity emanates from the fact that the daughter cells possess the same kind and number of chromosomes as the parent cell.
Hence, a nucleus that has eight (8) chromosomes during interphase will possess 8 chromosome in each daughter cell at the end of mitosis. Mitosis, which consists of stages, duplicate its DNA at the interphase stage but do not increase the chromosome number. Sister chromatids are formed for each chromosome, which separate during anaphase stage, and become individual chromosome in each daughter cell.
In this case, 8 chromosome are still formed at interphase but 16 sister chromatids. These chromatids separate equally into each daughter cell i.e 8 in each cell to become individual chromosomes.
Answer: As the mass of star increases, the temperature and luminosity also increases.
Explanation:
This can be described in what happens in main sequence star( example, the Sun), which is powered by fusion of hydrogen into helium in its core. Main sequence star exhibit a common characteristic which is hydrostatic equilibrium. This means,the inward force of gravity, which tends to compress the star, is balanced by the outward force due to the pressure. Thus when an extra mass such as hydrogen is added to its core, there will be increase in mass which leads to a higher compression. This in turn will lead to central density and temperature. As the temperature increases, fusion of gases occurs faster resulting to a much higher luminosity. I hope this helps, thanks.
