particles that make up matter are always cells
The correct answer is option D, None of the choice.
Prokaryotes like Escherichia coli are used in drug production. Rhizobium bacteria (prokaryotes) in the soil, form symbiotic relationship with the roots of the plant to fix nitrogen. And prokaryotes are measured in terms of colony-forming units (CFU) of bacteria to produce nutritious yoghurt.
Atoms gain electrons to form anions.
Atoms lose electrons to form cations.
Back in middle school, my chemistry teacher taught me a good way to remember whether an ion was a cation or an anion. When an atom loses an electron, it becomes positive, and when an atom gains an electron, it becomes negative.
Cation sort of sounds like “cat,” which is positive (Yay! Cats!).
Anions, on the other hand, sounds like “onion,” which is negative (Ew! Onions!).
There’s other ways of memorizing it, but this way was the easiest for me.

Um your question is very unclear lol
Answer:
C. genes
Explanation:
Genes are basic physical & functional unit of heredity. Genes are made up of DNA or we can say that they are segments of DNA which have instructions to synthesize bio molecules known as proteins and these protein molecules are further responsible for characteristics of an organism. Genes are located at a specific location in our chromosomes and the location is known as locus. Almost all the characteristics which an organism has depend upon the kind of information they have in their genes.
During developmental stages, how an organism will develop totally depends upon what kind of proteins are being synthesized at that time and as already explained, protein synthesis totally depends upon type of genes present in the organisms.
