Hello, I figured your question was missing its options so I went online and found them.

If mitotic cell division is the only way a particular species of single-celled organism can reproduce, it is most likely that

(1) mutations can not occur in this species.

(2) the rate of evolution in this species is slower than in one that reproduces sexually.

(3) the number of organisms of this species in an area will remain constant.

(4) this species belongs to the animal kingdom.

The correct answer is: the rate of evolution in this species is slower than in one that reproduces sexually.

Explanation:

If a unicellular organism only reproduces by mitotic cell division, its evolution rate is going to be slower than an organism that reproduces sexually because sexual reproduction plays an important role in generating mutations that could be positive for the organism and its offspring.

Mutations would occur all the same in this cell because errors can happen in the regulatory mechanisms in every process of cell division.

The number of organisms of this species would not remain constant as mitotic cell division generates 2 cells out of 1, so the number of organisms should always be ascending.

Clearly, a unicellular organism that does not reproduce sexually ISN'T in the animal kingdom. All animals are eukaryotic multicellular individuals that reproduce sexually.

bradykinin is a physiologically and pharmacologically active peptide of the kinin group of proteins, consisting of nine amino acids.

answer: zinc is the substance which has a volume of 1.38 .

density is defined as the mass of an object per unit volume.

it can be calculated by dividing mass of a substance by its volume i.e.

si unit of density is kg per cubic meter and cgs unit of the same is gram per cubic centimeter.

now from the given data volume can be calculated by the formula .

hence, the volume of aluminium will be = which comes out to be 1.703 .

similarly, volume of zinc, chromium, and nickel will be 1.378 , 0.869 , and 0.356 respectively.
