True because communities are just groups of organisms that live together, without them there would be no food chain and no way to have particular adaptations to environments because no animal would live in one place long enough
Answer:
trait: is a characteristic of the organism they include hair color or leaf color, size and even shape. a trait with a genetic contribution is called a genotype and they way or the outward expression of that genotype is called a phenotype.
gene: is a segment of that DNA some of the genes can give instructions in order to produce proteins
alleles: it is a version of a gene and they are located on the same part of the chromosome and we normally inherit 2 alleles for each gene
Explanation:
An atom is the smallest known unit and it is present in all the matter. The space occupied by atom is divided into two components: the nucleus and orbitals. The nucleus is the center of the atom, and orbitals surround the nucleus.
Location of protons-
Protons are positively charged particles within atoms. Each atom has at least one proton. The number of protons determine the identity of an atom.Protons reside in the nucleus of the atom.
Location of Electron-
Electrons travel around the nucleus in the orbital. Electrons are negatively charged particles. In a neutral atom, the number of electrons and protons are same. Though they are much smaller than protons but have the same strength charge.
Location of Neutrons-
Neutrons are located with protons in the nucleus. They have no charge and have the same mass as protons. Not all atoms have neutrons, and the number of neutrons is not usually the same as protons or electrons.
Part B-
I agree with Jane's statement as an aluminium atom has a dense central nucleus surrounded by negatively charged electrons, The protons and neutrons are closely packed in the center an 13 electrons are surrounding this center.

Answer & Explanation:
There are four main stages of mitosis. Those are prophase, metaphase, anaphase, and telophase.
The stages are also shown below on the diagram. Hope this helps!
