Answer:

When a male pig from a line of true-breeding (homozygous) black, solid-hooved pigs was crossed to a female from a breed (homozygous) of red, cloven-hooved pigs, their several progeny all looked alike with regard to color and hooves. These progeny were all mated to members of the same breed as their red, cloven-hooved mother pig. The offspring from this final cross were: 11 black, cloven-hooved; 8 black, solid-hooved; 14 red, cloven-hooved; and 10 red, solid-hooved. For each of these two genes (coat color and hoof type) determine which allele is the dominant one. Explain your reasoning. What were the phenotypes of the progeny produced by the first mating in this problem.

Answer:

Water has properties of cohesion and adhesion.

Explanation:

The single Hydrogen atom and double Oxygen atoms attach to each other in such a way their are minute polar polarity differences. Electron bonds will combine to form one side of the compound as being positive and the other side positive. Positive side of other H2O molecules will attach to the negative side. This bond causes water to adhere to sides of a glass test tube.

Will also create a bead when it drips on another non-porous surface. Adding soap will break the bead (surfactant). Water is the perfect solvent.

between an animal cell and a plant cell there are some parts that are similar and carry out the same function like:

both have a cell membrane which selects what goes in the cell.

both have cytoplasm which holds the protoplasm(the living part of the cell)

both have a nucleus which carries out all cell activities and holds threads of DNA called chromosomes

both have a mitochondria which is the power house of the cell

both have golgi bodies which modify and carry proteins from sites of synthesis to sites of reaction
