Explanation:
The allele for sickle cell would gradually be eliminated from the populations over generations. This is because while initially natural selection favoured and fitted the allele in the environment because its bearers are less vulnerable to malaria, sickle cells also result in reduced capacity of the red blood cells to carry oxygen to tissues. Therefore in the absence of Malaria, sickle cell would thereby offer a disadvantage to an individual hence be eliminated by natural selection.
Answer:
The units of both types of energy are Joule (kg × m² × s⁻²).
Explanation:
Step 1: Show the units of kinetic energy
The equation for kinetic energy is:
K = 1/2 × m × v²
where,
m: mass
v: speed
The units are:
K = 1/2 × m × v²
[K] = kg × (m/s)²
[K] = kg × m² × s⁻² = J
Step 2: Show the units of gravitational potential energy
The equation for gravitational potential energy is:
G = m × g × h
where,
m: mass
g: gravity
h: height
The units are:
G = m × g × h
[G] = kg × m/s² × m
[G] = kg × m² × s⁻² = J
Answer:
Pollination is the act of transferring pollen grains from the male anther of a flower to the female stigma. The goal of every living organism, including plants, is to create offspring for the next generation. One of the ways that plants can produce offspring is by making seeds.
