Answer:
A. The atom is mostly empty space.
B. Electron orbit around the center of the atom.
C. The atom's positive charge is located in the atom's nucleus.
Explanation:
Rutherford is a chemist which performnan experiment in order to see what is present inside the atom. He bombarded radiation from a source on an atom. He observed that most of the radiation pass through the atom so he concluded that the atom has mostly empty while some comes back which means that a heavy particles are present in the nucleus.
Answer:
Mitosis is the cell division in which a single is divided into the two daughter cells. The genetic constituent remain same in this type of division and known as equational division.
Four phases of mitosis are metaphase, prophase, anaphase and telophase. Prophase is the first stage in which the nuclear envelope disintegrates. The cohesion joins the sister chromatid together. In metaphase stage the chromosomes gets arranged at the metaphase plate and microtubules are attached to the kinetochores. The cohesin break downs and the sister chromatid moves towards the opposite poles at the anaphase stage. The telophase stage results in the formation o the nuclear envelope and spindle microtubules disassemble at this stage.
Answer:
1. Occupy different niches
They are known as C)Epiphyses
Answer:
b.You measure the quantity of the appropriate pre-mRNA in various cell types and find they are all the same.
Explanation:
You are given an experimental problem involving control of a geneʹs expression in the embryo of a particular species. One of your first questions is whether the geneʹs expression is controlled at the level of transcription or translation is you measure the quantity of the appropriate pre-mRNA in various cell types and find they are all the same.
