In light of my perception, I can finish up the accompanying:
1)Test life form A matures lactose
2)Test life form A delivered gas
3)Test life form A brought down the pH of the medium
<span>4)Test life form B does not mature lactose</span>
The earth has a closed atmosphere. This means that no water can be added to it. That's why we have the water cycle
The male
human has a sperm cell and the female has an egg cell. The cells from the male
and female that combine to form a zygote are called gametes. The human sperm
and egg cells each contain 23 chromosomes. . A combination of gametes forms a
zygote with 46 chromosomes. The type of cell division that produces gametes
with half the normal chromosome number is the meiosis. Meiosis is the type of
cell division used in sexual reproduction. It will occur in the testes and
ovaries.
Allele frequencies in a population may change due to four fundamental forces of evolution: Natural Selection, Genetic Drift, Mutations and Gene Flow. Mutations are the ultimate source of new alleles in a gene pool. Two of the most relevant mechanisms of evolutionary change are: Natural Selection and Genetic Drift.
Explanation:
By osmosis, due to the difference in osmotic pressure on either side of the membrane, the water passes through the membrane, which means that the water moves from high osmotic pressure / concentration regions to low pressure / concentration regions to a stable state. Thus, water moves from hypotonic regions (low solute concentration) to hypertonic regions (high solute concentration).
