<span>-A nucleus of an atom can be compared to the sun of a solar system because the nucleus, like the sun, is the largest part of an atom and its electrons orbit around it, much like planets in a solar system.<span> Atoms can also gain or lose electrons similarly to how stars can gain or lose planets.

And, it keeps the things that are outside the yard from getting into the yard. Every once in a while it lets a few select things either go in or out.

Answer:
Cross the green-pod plant with a yellow-pod plant.
Explanation:
To determine the zygosity of a particular individual, the best way is to cross it with a phenotypically recessive individual.
Such a cross in which an individual with unknown zygosity possessing a dominant trait is crossed with an individual possessing a recessive trait is termed as a test cross.
Therefore, in the given situation the zygosity of the green pod needs to be determined and the green pod is a dominant character. Further, it is given that a yellow pod is a recessive trait, therefore a test cross can be performed between the green pod and yellow pod, and then the offsprings can be observed.
if the offsprings are all phenotypically dominant then the green pod is homozygous and if there are phenotypically recessive offspring also present then the green pod is heterozygous genotypically.
C) DNA is made of 4 types of nucleotides
Not all organisms have 46 chromosomes (23 homologous pairs). Not all organisms have nuclei (e.g. bacteria do not have nucleus)
Answer:
D
Explanation:
It can't be A as nuclei must be positive.
It can't be B as nuclei must contain at least one proton, and no electrons.
Technically C may be true, but the question is asking about the nucleus. Not the electron cloud. Electrons aren't found in the nucleus. Only protons and neutrons.
