Answer:
tiny germs, bacteria, illness
Explanation:
these these three are diseases that cause by the viruses because people that have illness could have tiny germs and bacteria and if they do they need to stay home and get treatment to get better. Hope to answer your question

Answer:
Three Laws of Biology. “Social rules can be broken, but the laws of nature can't.”
A biological rule or biological law is a generalized law, principle, or rule of thumb formulated to describe patterns observed in living organisms. Many of these regularities of ecology and biogeography are named after the biologists who first described them.
Answer:
Homology is a study of similar characters found in two species because of common ancestry.
Explanation:
1.Morphological homology: Species placed under same taxonomic category exhibit similar anatomical structures.
2.Ontogenetic homology: Species belongs to same taxonomic category embryological similarities
3.Molecular homology: Species show molecular similarities such as DNA,RNA and protein
An example of homology is seen in the skeletal strycture of vertebrates. That is arm of a human,leg of a cat,fin of a whale and wing of a bat.
Answer:
CDK is inactive without a cyclin bound to it.
Explanation:
CDKs are the cyclin-dependent kinases. These protein kinases serve to regulate the various stages of the cell cycle. Cyclins are the regulatory proteins. The levels of cyclins fluctuate during the cell cycle. Cyclins bind to respective CDKS to activate them. Unless cyclins bind to CDKs, these protein kinases are inactive. Cdk associates with cyclin and forms a cyclin–Cdk complex. For example, mitosis specific Cdk bind to cyclins and activated M-Cdk then activates the proteins that facilitate mitosis and inactivate the one that inhibits mitosis.
