What factors influence the input and output of carbon through Earth's spheres? The oceans on Earth act as carbon sinks. The combustion of fossil fuels contributions to an increase in atmospheric carbon dioxide. Animals are solely responsible for the release of carbon dioxide via respiration
Answer:
The correct answer is B. All organisms would appear purple (gram-positive).
Explanation:
Gram staining is done to differentiate between gram positive and gram negative bacteria. Gram positive bacterial cell wall is made up of peptidoglycan which dehydrates and shrinks after decolorizing step and large crystal violet and iodine complex do not comes out making them purple in this process.
But in gram negative bacteria the cell wall is made up of lipids in which the crystal violet-iodine complex comes out due to the degradation of lipid by decolorizer.
So when the student forgot to decolorize bacterial sample crystal violet do not comes out from gram negative cell wall making them purple like gram positive cells. So all organism will appear purple.

The human immune virus cannot reproduce without host cells.
<h3>Human immune virus</h3>
The human immune virus is an RNA virus that only becomes active in human hosts.
When the virus gains access into a suitable host, it embeds its genome into that of the host and as such, the genetic machinery of the host is utilized to multiply the genome of the virus.
With time, the virus gradually takes over the host's genome system and breaks down their immune system, making them susceptible to diseases.

Answer:
It is beneficial to study plant and animal compounds for a multitude of reasons such as Sanitation, Bacterial fighting, and many more. An example of a plant compound that has benefited humanity would be penicillin which is derived from plants, it is considered the first true antibiotic.
Explanation:
Before 1928, humanity had conquered most of its enemies and people were only limited in lifespan by internal mechanisms being disrupted or failing, such as cancer, genetic errors,viruses, and BACTERIA. But in 1928 by accident a scientist discovered penicillin and finally deaths by bacteria were dropping to the point where in the past a mere cut could mean death by bacterial infection when compared to the present, humanity now doesn’t even consider bacterial infection, and that is all due to the power of penicillin and other antibiotics.
Water is a polar compound because there is a positive hydrogen end and a negative oxygen end, this is caused by an uneven electron distribution
