Answer:
A. Air
Explanation:
Abiotic factors are things that are not living.
Air can be found in a rain forest ecosystem, as it can be found in all ecosystems, but it is not living.
On the other hand, algae, flowers, and animals are biotic instead of abiotic because they are living things.
So, A is the correct answer.
Answer:
In C4 photosynthesis, where a four-carbon compound is produced, unique leaf anatomy allows carbon dioxide to concentrate in 'bundle sheath' cells around Rubisco. This structure delivers carbon dioxide straight to Rubisco, effectively removing its contact with oxygen and the need for photorespiration
When a cell undergoes meiosis,the outcome of the process is FOUR HAPLOID CELLS.
Meiosis refers to a form of cell division which always results in the formation of four daughter cells. The four daughters cells produce have diploid cells which contains half the original of chromosomes from the parents. A diploid cell has two of each chromosome, one from each parent. The eggs and the sperms that are involved in reproduction possess haploid cells. In meiosis, the whole process start with diploid cells which divide twice to produce four haploid cells.

Explanation:
The scientific name of a species tells you the genus and the species name of an organism.
The identification of an individual by the means of genetic engineering is possible because the Y chromosomes in the males does not experience any crossing-over as there is only a single Y chromosome present in a human male.
The mitochondrial DNA is passed from the mother to child in the cytoplasm of the cell, and it is passed on without any changes. The X chromosome is can be passed from a mother to her son as he will receive Y chromosome from his father.
Hence, the correct answer is 'Option B - The Y chromosome does not experience crossing over'.
