Crop rotation does all the things listed in the options exceptoption d. organic fertilizer.
Crop rotation is a farming practice that involves the systematic planting of different crops in a specific order over time. It offers several benefits to agricultural systems, including minimizing erosion, letting fields lie fallow (rest) to restore soil health, and returning nutrients to the soil. However, crop rotation itself does not involve the use of organic fertilizer. Instead, it focuses on the strategic arrangement of crops to enhance soil fertility and reduce pest and disease buildup.
Therefore, the correct answer is d) organic fertilizer.

Three sources of genetic variation are mutation, recombination and gene flow.
Genetic variation is the differences in the genetic makeup of individuals within a population.
The sources of genetic variation are;
Mutation: Mutations are random changes that occur in an organism's DNA sequence.
Recombination: Recombination occurs during meiosis, the process by which gametes (e.g., sperm and egg cells) are formed.
Gene Flow: Gene flow refers to the movement of genes between populations. This occurs when individuals from different populations interbreed and exchange genetic material.

Both Gradualism and punctuated equilibrium are explanations of the rate of evolutionary change. Therefore, the correct answer is A
Gradualism and equilibrium are two different ways in which the evolution of species can take place.
Gradualism is a variation that occurs gradually and can be cannot be recognized easily over a short period. Evidence of gradualism has been found by scientists in the geologic process. Scientists describe gradualism as some of the processes that are going on in earth’s landforms and surfaces. They also pointed out that the mechanisms it contained, erosion, plate tectonics combines the processes that in some aspects appear destructive and others constructive.
Punctuated equilibrium, on the other hand, has to do with the notion that since no changes can be seen in a species, there must however be a period when no changes take place. Punctuated equilibrium maintains that evolution happen in a short burst with a longer period of equilibrium.
One of the scientists that proposed punctuated equilibrium is William Bateson, he argued that species can only evolve rapidly and not gradually. He believed that evolution occurs rapidly in a species with a long period of stability.
Thus, Both Gradualism and punctuated equilibrium are explanations of the rate of evolutionary change. Both are accepted ideas of how evolution occurs in a species.

Bacteria and archaea differ in their cell walls makeup.
Further Explanation:
Archaea is considered to arise many years ago and is also considered to be the most primitive form of life. Earlier they were classified as bacteria but as they possessed certain difference features when compared with bacteria, it was now termed as archaea. Some of the characteristics of archaea resembles eukaryotes while other resembles with prokaryotes.
Archaea are single celled organism and they can thrive in harsh conditions like marshy area and hot springs. Some of the example of archaea are, Thermococcus litoralis, Methanopyrus kandleri, Cenarchaeum symbiosum etc.
The features of archaea which are similar to bacteria are:
1. Lack of nuclear envelop.
2. Lack of membrane bound envelop.
3. Presence of circular chromosomes.
The features of archaea which are similar to eukaryotes are:
1. Methionine is the initiator amino acid for protein synthesis.
2. Lack of peptidoglycan in their cell wall.
3. Association of histones with DNA.
