Which chemical components may be parts of a molecule of transfer RNA? A) ribose, phosphate group , uracil base

B) deoxyribose, phosphate group , guanine base

C) glucose, amino group, thymine base

D) maltose, carboxyl group, uracil base

A) ribose, phosphate group , uracil base

Explanation:

tRNA nucleotides (monomers) have:

Deoxyribose = sugar found in DNA only

Thymine = nitrogenous base found in DNA only

Uracil = nitrogenous base found in RNA only

Maltose = complex sugar that has nothing to do with genetic material

Carboxyl group = not found in genetic material

correct answer: biotic and abiotic limitations

carrying capacity is defined as the total number of an organism who can be supported in a given area within the natural resources limit and without harming or degrading the natural, economic or the cultural environment present for the future generations.

carrying capacity is determined by the limiting factors, which are known to affect the natural resources available. it may include water, nutrients, minerals, space, light etc.
