Answer:
In biology, biotic components can be described as the living components of an ecosystem. Abiotic components can be described as the non-living components of an ecosystem. Both, the biotic and abiotic factors are important in maintaining a stable ecosystem whether it be a terrestrial ecosystem or an aquatic ecosystem.
Some of the abiotic factors which affect the distribution of the aquatic life are:
- <em>Amount of light: </em>The area which will receive more light will result in greater biodiversity. This is because there will be more number of plants in this area of the water and more plants means that there will be more aquatic animals present to feed on these plants.
- <em>Water flow rate: </em>Some organisms in the water are sensitive to high flow rate. More diversity will be seen in areas where the water flow is stable.
- <em>Temperature: </em>Although many of the fishes are cold-blooded, yet there will be greater diversity where the temperature will be moderate.
Some of the biotic factors which affect the distribution of the aquatic life are:
- <em>Predators: </em>If there are more number of predators than the preys, then the prey diversity will have a serious threat.
- <em>Aquatic plants: </em>There will be more aquatic biodiversity in the areas where there will be more aquatic plants.
Answer:
A missense mutation is a mistake in the DNA which results in the wrong amino acid being incorporated into a protein because of change, that single DNA sequence change, results in a different amino acid codon which the ribosome recognizes. Changes in amino acid can be very important in the function of a protein.
Answer:
<em>Staphylococcus aureus</em>
Explanation:
According to the rule of binomial nomenclature, the name of the organism is written in two parts that are-
1. Generic name- The first name which signifies the genus of the organism, the word represents the noun of the organism, the first letter of the word is always uppercase that is like in the "Staphylococcus"
2. The specific epithet-the second name of the organism represents the species which is usually a noun, and the first letter of species is always written in lowercase like in the aureus.
The scientific name should be written either in the italicised form or if not possible to write in the italicised form than underline the name.
Thus, <em>Staphylococcus aureus </em>is correct.
