Basically, the P-P chain turns 4 protons into: 1 neutrino, 1 gamma ray, 1 positron, 1 helium nucleus.
A gamma ray = energy.
The chain converts hydrogen into helium and makes energy.
This is all occurring through fusion reactions where 2 protons basically smash into each other. But, it could also be e.g. a proton smashing with a deuterium nucleus. Or, other nuclei smashing together to make something else.
Hope this helps!
In mitosis, the first stage is prophase. The
nucleolus disappears and the two centrosomes begin to form the mitotic spindle.
The spindle xtends between two opposite poles f the cell. Next is the
metaphase. The centromeres of the chromatid pairs align at the center of the
miotic spindle. Then anaphase, the centromeres will split that separates the
chromatid pair. They are now called chromosomes. The last phase is the
telophase. The chromosomes will then form a thread-like chromatin and for ache
envelope, a nucleoli appears. <span>The type of
cell division that produces gametes with half the normal chromosome number is
the meiosis. Meiosis is the type of cell division used in sexual reproduction.
It will occur in the testes and ovaries.</span>
Arrow symbol →
Explanation:
The arrow symbol in a chemical equation separates the reactants from products.
A chemical reaction is process in which chemical changes leads to the formation of products from reactants.
The arrow symbol → is used to separate the reactants from products
⇆ shows reversibility of the reaction
↑ indicates that gas is given off as product

Answer:
No, because some eukaryotic genes have introns that are not translated.
