Answer:
Large population
Random mating
No evolutionary mechanisms (mutations, genetic flow,, genetic drift, natural selection)
Explanation:
According to Hardy-Weinberg model, allele frequence (or genotype frequencies) will remain constant through generations in the absence of disturbing factors, evolutionary mechanisms. Such constant population is in Hardy-Weinberg equilibrium (no evolving population). Factor that can disturb equilibrium of the population are nonrandom mating, mutations, gene flow, natural selection, genetic drift.
According to Hardy-Weinberg model:
p2+2pq+q2=1 (p+q=1)
p2 is the frequency of dominant homozygous genotype
2pq is is the frequency of heterozygous genotype
q2 is is the frequency of recessive homozygous genotype
Answer:
The placenta serves as an interface between the mother and the developing fetus and has three main jobs: Attach the fetus to the uterine wall. Provide nutrients to the fetus. Allow the fetus to transfer waste products to the mother's blood.
Explanation:
Answer:
Cellular respiration occurs in the mitochondria is the correct statement
Explanation:
Answer:
Because of the tilt of the earth on its axis. When the North Pole is tilted towards the Sun, the northern hemisphere experiences summer solstice. At this time, since the south Pole is tilted away from the Sun, the southern hemisphere experiences winter solstice.
That is why, When it is summer in the northern hemisphere, it is winter in the southern hemisphere. It's all because the Earth is tilted on its axis.
