Hydrogen Sulfide (H2S) Hydrogen sulfide is a colorless, flammable, extremely hazardous gas with a “rotten egg” smell. It occurs naturally in crude petroleum and natural gas, and can be produced by the breakdown of organic matter and human/ animal wastes (e.g., sewage).

The answer is B
Germination is when a seed starts to grow after a period of dormancy
The analysis of all an animal’s genes reveals more about its classification than behavior because fine-tuning evolution is evidenced by homo-logous sequences.
<h3>What is sequence homo-logy?</h3>
Sequence homo-logy refers to different nucleotide sequences that are similar due to a common origin.
Behavior may be due to the convergence of a feature in distinct lineages, but evolution is largely determined by homo-logy between gene sequences.
In conclusion, fine-tuning evolution is evidenced by homo-logous sequences.

In a diploid organism, one that has two copies of each chromosome, two alleles<span> make up the individual's genotype.</span>
<span>A.
Roots B.
Stem C.
Xylem D.
Phloem
The pathway that the viruses would most likely follow on first entering the plant is D. PHLOEM.
The phloem, whose purpose is to transport food from the leaves to the plant, is used as the pathway to spread the virus throughout the plant. The manifestation of aphid transmitted virus is the yellowing, mottling, or curling of leaves and the stunted growth of the plant.
