Just black?
Well it’s a colour which results from the absence of visible light. In technical sense black and white aren’t colour, but shades however, many people disagree since you combine other pigments to get black.

Answer:
Option-1 and 3
Explanation:
Cadherin is the protein complex present in the cell which is responsible for the sticking together of cell in tissue-like in the skin. The cadherin junctions allow the communication between the cells and the loss of the cadherin could cause cancer.
The cadherin junction is involved in the signalling pathway in the cells like in the Rho GTPase signalling, Ras signalling and many others which shows that they are responsible for the biological processes in an organism.
Thus, Option-1 and 3 are correct.
Answer:
4 of the 8 pups should have white hair.

Animal cells have a cell membrane and not a cell wall. They have ribosomes and lysosomes and their nucleus is enveloped by a nuclear membrane. This means that the first description;
Cell membrane present;
ribosomes present;
lysosomes present;
nuclear membrane present.
Matches ANIMAL.
Plant cells on the other hand have something called a cell wall, which are more rigid than cell membranes. Plant cells are known for their large vacuole. They also have a nuclear membrane that covers its nucleus.
The third description:
Cell wall present
Ribosomes present
Nucleus present
Large vacuole present
Matches PLANT.
Viruses do not have any membrane on its wall nor its nucleus. Basically, they have no internal structures. The fourth and last description:
Reproduces inside of a cell
Nucleus absent
RNA present
Matches VIRUS
Prokaryotes are primitive cells and they do have a cell wall but they have no defined nucleus, which means they do not have a nuclear membrane. The second description:
Cell wall present
Ribosomes present
Nuclear membrane absent
Matches PROKARYOTE
