Ans.
In humans, there are total of 46 chromosomes in each cell that show 23 pairs of chromosome. During reproduction, meiosis occurs in germ cells that leads to formation of daughter cells or gametes that contain half of the chromosomes as present in parent cells. Thus, each gamete (either male or female) contains 23 chromosome.
During fertilization, fusion of male gamete or sperm(with 23 chromosomes) and female gamete or ovum(with 23 chromosomes) to form zygote that develops into multi-cellular offspring with 46 chromosomes.
Thus, 'a child inherit 46 chromosomes from his or her parent (23 chromosomes from each parent).'
Hi :)
The role of membrane processes include desalting, disinfection by-product control, disinfection, clarification and removal of synthetic and inorganic chemicals
Hope this helps!
Answer: 448.15 Kelvin and 347 Farenheit
KELVIN- 175°C + 273.15 = 448.15K
Farenheit- (175°C × 9/5) + 32 = 347°F
Answer:
C.The two species do not breed in the same area, so they are reproductively isolated by allopatry.
Explanation:
Allopatry means that these two species are geographically separated during the breeding season, so they are reproductively isolated.
Allopatric speciation is a form of speciation (creation of new species) that occurs as a result of geographic isolation. This means that a part of population becomes physically separated from the initial main population. There is no gene flow between these two populations and as a result the two populations reach a high level of genetic divergence. They can no longer interbreed which means they become two different species (speciation).
