I am pretty sure that your answer is C or D. Im not sure between the two which. Sorry.
Answer:
They allowed businesses to operate with few regulations.
Four hydrogen nuclei are converted to helium nuclei in the proton-proton chain. This does not occur naturally on Earth because the process requires it. extremely high temperatures, pressures, and densities
The proton-proton chain is a series of reactions that fuses four hydrogen nuclei to form one helium nucleus. The energy is derived from the mass difference between the four hydrogen nuclei with higher masses and the single helium nucleus with lower masses. Energy is released when hydrogen is fused into helium: mass to energy conversion. Because mass is created during the proton-proton chain, energy is released. However, this is essentially the end of the story for the nuclear fusion reactions that occurred in the early Universe, known as Big Bang Nucleosynthesis.

Answer:
functions as adhesion and address loci for cells.
Carbohydrates protect the cell by forming a glycocalyx, which is especially strong in bacteria and enables biofilms to form.
Explanation:
The early shape of the fetal brain most resemble a tube. The fetal development starts after conception. After about four weeks the neural tube together with the back is closing. The fetal brain and the spinal cord will develop from the neural tube. Then the other organs and the heart are also starting to form.
