Activated charcoal adsorbs many noxious substances—medical drugs, phytotoxins and poisonous chemicals—onto its surface, preventing their absorption from the gastrointestinal tract.
<h3>What is activated charcoal ?</h3>
Activated carbon, sometimes known as activated charcoal, is a type of carbon that is frequently used for a variety of purposes, including the filtration of impurities from water and air. It is treated to have tiny, low-volume holes, which expand the surface area open to chemical reactions or adsorption.
- For some poisonings, activated charcoal is utilised as an emergency therapy. It aids in preventing the body from absorbing the toxin from the stomach. To treat severe poisoning, activated charcoal may occasionally be given in multiple doses.

Answer:
The correct answer is 2. 5'-AUGUCAGGUACGCCACAU-3'
Explanation:
The template strand for transcription is 3'-TACAGTCCATGCGGTGTA-5 and RNA polymerase will add complementary mRNA sequence against this strand in the opposite direction i.e., 5' to 3' direction.
In RNA, A(adenine) makes complementary base pairing with U(uracil), not with T(thymine) and the rest of the base-pairing is same as in DNA. Therefore the correct mRNA produced from the transcription of this DNA molecule by the help of RNA polymerase is 5'-AUGUCAGGUACGCCACAU-3'.
Then this mRNA sequence will be used by ribosomes to synthesize proteins during the translation process.
Answer:
express different genes
Explanation:
cells of a multicellular organism have the same genes with the same chromosomes
however their expression varies from cell to cell depending on their function
Answer:
Option B, Foundation species
Some examples of foundation species are - Corals, Earthworms, Beavers etc.
"The proportion of Neanderthal-inherited genetic material is about 1 to 4 percent [later refined to 1.5 to 2.1 percent]. It is suggested that 20 percent of Neanderthal DNA survived in modern humans, notably expressed in the skin, hair and diseases of modern people.Extinction of a particular animal or plant species occurs when there are no more individuals of that species alive anywhere in the world - the species has died out. This is a natural part of evolution. But sometimes extinctions happen at a much faster rate than usual.
