The statement B is correct. Abiotic factors are the non-living factors which include rocks, soil, water, minerals, gases etc. Biotic factors are the living factors like animals, plants, humans etc. Rocks are abiotic factors and they have no life. They are not made up of living cells and do not require food for growth.

The answer is D. The living things in a biological community are called biotic components. Living things incorporate plants, creatures, microscopic organisms, parasites and that's only the tip of the iceberg. The non living parts of an environment are called abiotic elements. In a biological community some abiotic variables are daylight, temperature environmental gasses water and soil.

Charra [1.4K]

When population reaches it's maximum size and is in a steady state, it is said that the Carrying Capacity has been reached.

Explanation:

Carrying capacity is defined as the maximum number of individuals of a population an ecosystem can support without being stressed out.
When a population reaches its carrying capacity it is in a stable state and can be easily maintained by the available resources.
But if carrying capacity is exceeded then it will create a shortage of resources and increase competition in the ecosystem.

There are only about 40 different tRNAs in a cell even though 61 codons code for amino acids. This discrepancy can be attributed

bogdanovich [222]

Answer:

The correct answer is - wobble; the curvature of the anticodon loop; inosine.

Explanation:

The wobble phenomenon or hypothesis tells that why there are multiple codons are present for a single amino acid. 20 amino acids are coded by 61 codons. It states that tRNA can identify and attach to more than one amino acid due to the curvature of the anticodon loop.

The curvature of the anticodon loop is that the base at the 1st position on the anticodon to binding but the less-precise base pairs that can arise between the 3rd base of the codon. The inosine is the nucleoside that presents in a position in the curvature of the anticodon loop and its position responsible for wobble as well.
