The correct answer is D.
From the scientific research conducted so far, we know that in the early Earth's history the atmosphere lacked oxygen and was mostly filled with other gases like methane. The increase in oxygen levels happened when the plants started producing oxygen as a byproduct of the process of photosynthesis.
The research so far also shows that the RNA was present before the DNA and that the microspheres might have been essential to the development of life on Earth.
Answer:
1/3
Explanation:
The first thing to do is to figure out all possibilities.
I'll use f for female and m for male.
The possible outcomes are: 5f, 4f 1m, 3f 2m, 2f 3m, 1f 4m, or 5m.
Since there are 6 possible outcomes, and 2 of the outcomes are 2 males and 3 females or 3 males and 2 females, the probability is 2/6 or 1/3!
Answer:
Likewise, logistic growth (that's what the problem is called, the logistic curve is the variable that moves between the Y and X axes) is a refinement of exponential growth.
Explanation:
The exponential function is a valid model for continuous growths or decreases in which the conditions are always equally favorable: increase of the capital entered into a bank, disintegration of radioactive substances ... The populations of living beings begin to grow according to an exponential curve but if there are no catastrophes, they invade their vital space and, due to the limitation of food, etc., their growth is cushioned, not exceeding their limit population. This type of increase, dampened by a saturation level is called logistic growth.
<h2>Inbreeding </h2>
Explanation:
Inbreeding is defined as the formation of offspring which results from the mating of two closely related organisms
Inbreeding affects allele frequencies and genotype frequencies in a population in following ways:
- Inbreeding increases homozygosity
which in turn decreases the biological fitness of a population because there are chances that offsprings will be affected by deleterious traits in this case
- Inbreeding itself does not cause evolution, because allele frequencies do not change in the population as a whole
