Answer:
B) 2pq
Explanation:
Hardy-Weinberg equilibrium refers to a model which explains the effect of evolution on the gene pool.
The model is based on the assumptions that if no evolutionary force like genetic drift, natural selection and many other will act on the population and therefore the gene pool (gene frequency and the genotypic frequency) of a populations remains in equilibrium or constant throughout the generations.
The genotypic frequency in the model is calculated by
P² = genotype of a homozygous dominant trait
q² = genotype of a homozygous recessive trait
2pq = genotype of heterozygous trait.
Thus, P²+2pq+q²=1
In the given question, since the population is in equilibrium that is no evolutionary force is acting, therefore, the genotype frequency remains the same that is the frequency of Aa will remain same that is 2pq even after 100 generations.
Thus, Option-B is the correct answer.

The process where a specie develops and evolves into new many species is termed as speciation. Macroevolution explores the mechanism of speciation where organisms across biological populations evolve as distinct population.
There are many causes to speciation, a) geographic isolation, b) gene flow reduction, and c) reproductive isolation.
Answer:
The correct answer is - sun - producer - the consumer – decomposer.
Explanation:
Sun is the ultimate source of the energy on the earth and is responsible for all the energy that is present or moves between various organisms in an ecosystem.
Sun provides energy in the form of light energy which is converted by the producers by photosynthesis into food and when consumers eat producers for food and energy 10 percent of energy passes from the producers to the consumers and the rest 90% lost during life processes. At the end of the chain, decomposers get energy from the dead matter of the consumers.
The giraffe head is higher than its heart so the blood pressure in the head must be lower than in the heart. The pressure is directly related to the density, gravity, and the height. The calculation would be:
<span>P = ρ*g*h
</span>P= 1.05* 10^3 kg/m3 * 9.8m/s2 * 2m= <span>20 580 pascals= 20.58 kpa</span>
