Which of the following is a part of an atom? a. proton
b. neutron
c. electron
d. all of the above

except for hydrogen (a proton and electron) all atoms have protons, neutrons and electrons.

Explanation: atomic nuclei have protons and neutrons, except for hydrogen, the simplest atom whose nucleus is a single proton. Neutrons help the positively charged protons in larger nuclei stay together. Protons and electrons have equal and opposite electric charge and equal numbers in neutral atoms. Atoms with extra or fewer electrons are called ions.

answer; atp and nadph;

prophase: we can observe the chromosomes to coil up and condense. they become visible. nuclear membrane and envelope disintigrate.s

metaphase: chromosomes align at the center, the metaphase plate. spindle fibers attach to centromeres of the sister chromatids. they meet at kinetochores.

anaphase: sister chromatids are pulled towards each opposing centromere, set on different poles.

telophase: chromosomes are now clustered up only on either sides of the cell. nuclear membranes reform, and a new cell wall forms along the cell plate. this will lead to cytokinesis, the process that divides the cell membrane and forms the cell wall.
