Eukariotic cells have nuclei, while prokaryotic cells do not.
Answer:
Brainliest
Explanation:
During metaphase, the chromosomes that carry genetic information align in the equator of the cell before they split off into two daughter cells with identical genetic material. Metaphase is the third stage of mitosis, which is a phase of the cell cycle where chromosomes in the nucleus are divided between two cells.
Answer:
Variation, in biology, any difference between cells, individual organisms, or groups of organisms of any species caused either by genetic differences (genotypic variation) or by the effect of environmental factors on the expression of the genetic potentials (phenotypic variation). Variation may be shown in physical appearance, metabolism, fertility, mode of reproduction, behaviour, learning and mental ability, and other obvious or measurable characters.
chromosomes or by differences in the genes carried by the chromosomes. Eye colour, body form, and disease resistance are genotypic variations. Individuals with multiple sets of chromosomes are called polyploid; many common plants have two or more times the normal number of chromosomes, and new species may arise by this type of variation. A variation cannot be identified as genotypic by observation of the organism; breeding experiments must be performed under controlled environmental conditions to determine whether or not the alteration is inheritable.
Genotypic variations are caused by differences in number or structure of Environmentally caused variations may result from one factor or the combined effects of several factors, such as climate, food supply, and actions of other organisms. Phenotypic variations also include stages in an organism’s life cycle and seasonal variations in an individual. These variations do not involve any hereditary alteration and in general are not transmitted to future generations; consequently, they are not significant in the process of evolution.

Answer: Hydrogen bonds.
Explanation: This seems like more of a chemistry question, but basically hydrogen bonding is way stronger than any other kinds of bonding, and because water molecules are all hydrogen bonded, they cling together a bunch and are thus super cohesive.
