Answer:
they are not getting enough sunlight to begin with the growth tends to become weak
Explanation:
Answer:
Human cells can readily absorb folic acid; bacteria cells cannot.
Explanation:
Bacterial cells cannot absorb folic acid and synthesize it. On the other hand, humans do not synthesize folic acid in their cells. They rather obtain it from the diet. Sulfa drugs, for example, sulfanilamide resemble p-aminobenzoate (PABA). PABA is a molecule that is used as a substrate in the synthesis of the coenzyme folic acid. The sulfa drugs serve as competitive inhibitors and compete with PABA for the catalytic site of an enzyme involved in the folic acid synthesis. This prevents the synthesis of folic acid in bacterial cells and thereby, inhibits bacterial growth.
<span>The
answer is Helium-4. These are two protons and two neutrons bound together. Alpha radiation
is the least powerful of the 3 types of radiation: the others being gamma and beta. Nonetheless,
it is the most densely ionizing. Alpha and beta radiation
release actual matter while gamma emits electromagnetic

I'm pretty sure it's D, because I had something like this last week. but I'm sorry if it's wrong..
Archaebacteria are like Eubacteria, which are just able to survive dangerous conditions, such as high salinity, extreme temperatures, and no oxygen.
Eubacteria are your garden-variety prokaryotic organisms that can cause the common cold and make bread rise, which don't have nuclei.
Fungi are similar to plants in the way that their cells are structured, except they have cell walls made of <em>chitin</em>, instead of cellulose like Plants. They decompose food and eat it using chemosynthesis, breaking it down into organic matter, which allows for the cycling of materials through a food chain.
Protista is really tough. You see, protists are basically a fancy word scientists picked instead of "miscellaneous", because there are plant-like, fungi-like, and animal-like protists. They really have no defining characteristics to speak of except that they have weird quirky qualities that don't allow them to fit in any groups.
Hope this helped! :)
