The Hardy-Weinberg equation is:
where p generally represents the frequency of the homozygous dominant population.
The q usually represents the frequency of the homozygous recessive population, and the 2pq term represents the frequency of the heterozygous population.
Answer:
1. There are three type of population distribution namely uniform, random and clumped.
a) Uniform distribution also know as a rectangular dispersal or distribution that has constant probability. This is also a family of symmetric probability distributions.
b) Random distribution takes place where individuals are spaced at unpredictable spaces or distances from each other.
c) Clumped distribution is when individuals in a population are clustered together, making some patches with other organism or individuals.

Answer:
When the inside of the Earth was liquid, gravity caused the heavier elements nickel and iron to sink to the center. Lighter elements floated to the surface. Over time this process caused the Earth to separate into layers.
Explanation:
As Jerry nears the campfire, he is delighted at the warmth it provides. Jerry perceives this temperature because of thermoreceptors in his skin.
<h3>What are thermoreceptors?</h3>
- The receptive part of a sensory neuron, or more precisely a non-specialized sense receptor called a thermoreceptor, is responsible for coding absolute and relative changes in temperature, primarily those that fall within a safe range.
- Warmth sensors are assumed to be unmyelinated C-fibers in the mammalian peripheral nervous system (low conduction velocity), whereas cold receptors have both C-fibers and sparsely myelinated A delta fibers.
- Warm receptors respond well to warming, which causes them to discharge action potentials more quickly.
- For cold sensors, cooling causes an increase in firing rate whereas warming causes a reduction.
- A paradoxical reaction to heat is when some cold receptors react to high temperatures, usually above 45 °C, by releasing a short action potential.
