Answer:
A. Resolution is the correct answer.
Explanation:
Oil immersion is used to increase the numerical aperture and resolution power of the microscope.
Oil such as cedarwood, paraffin oil which has a high refractive index is used and placed between a slipcover and an objective lens that increases the resolving power. This completely immerses the light way among the lens and object observed and allowing more precise features to be observed.
Oil immersion is required for observing unique bacteria and parts of the striations muscle.
1. What happens in the process of natural selection;
<span>Natural selection is the process which organisms with variations most suited to their local environment survive and leave more offspring. Natural selection occurs in any situations in which more individuals are born than can survive (the struggle for existence), there is natural heritable variation (variation and adaptation), and there is variable fitness among individuals referred to as survival of the fittest.
2. Organisms with greater fitness generally leave more offspring than organisms that are less fit.
This is because </span><span>the organism is better adapted to their environment than the other organism. They can survive and reproduce more while individuals with characteristics that are not suited for their environment either die without reproducing or leave few offspring and are said to have low fitness.

3. Similarity and differences between natural selection and artificial selection;
<span>In both artificial and natural selection, only certain individuals in a population produce new individuals. However; in natural selection, the environment- not a farmer or animal breeder- influences fitness.</span>
4. Hutton's and Lyell's ideas are important to Darwin;
This is due to the fact that they both <span>contributed to Darwin's theory, which implies that life has been on Earth for a very long time- enough time for all this descent with modification to occur. They stated that: Deep time gave enough time for natural selection to act. For evidence of descent with modification over long periods of time, Darwin pointed to the fossil records.
5. Evolutionary tree and what it implies about all species living and extinct
</span><span>Evolutionary tree or phylogenetic tree is a diagram that represents evolutionary relationship among organisms. The evolutionary trees show the diversity of life on the idea that species change over time. They imply how all organisms are related.
6. Structure of the lion's teeth an adaptation to the lion
Adaptation involves heritable characteristic that increase an organism's ability to survive and reproduce in an environment.
The structure of lion's teeth is an adaptation to the lion because they increase the lions ability to kill prey and tear meat, making it adaptable to an ecosystem and increasing its survival. </span>
31.3% of all S. aureus isolates collected during the study period were resistant to mupirocin
Animals and plants need to get rid of carbon dioxide gas through a process called respiration. Carbon moves from fossil fuels to the atmosphere when fuels are burned. When humans burn fossil fuels to power factories, power plants, cars and trucks, most of the carbon quickly enters the atmosphere as carbon dioxide gas.
Reforestation is a biodiversity method that can increase the biodiversity by replanting with trees. Reforestation will help forest recuperate from logging, rest fires and human abuse. Replanting trees will increase the density and variety of the trees and by doing so, wildlife will also increase. Although reforestation is a common approach to relive forest, forest management is still needed to maintain the endemic or native species.
