Why was helium and hydrogen the first elements to show up in the universe?
laiz [17]

Hey there! I could help you out with your question.

°.✩┈┈┈┈∘*┈┈୨♡୧┈┈*∘┈┈┈┈✩.°

According to research it claims that "Within about 3 minutes after the Big Bang, conditions cooled enough for these protons and neutrons to form hydrogen nuclei. ... This is when recombination occurred — neutral hydrogen (and helium) finally appeared because they could “recombine with” (hold on to) electrons without easily losing them to stray radiation."The Big Bang created the elements on the periodic table, building blocks that help make up the universe. ... In stars, hydrogen atoms fuse to create helium — the second most common element in the universe, according to Encyclopedia.com. Helium has two protons, two neutrons and two electrons. Hydrogen is known to be the first element in the periodic table of elements. It has one proton in its nucleus and one outter electron. It is a very light gas and also flammable. ... Its atomic symbol is H and its atomic number is one.

The function of the villi and the microvilli is to increase the amount of surface area available for the absorption of nutrients. Each villus has a network of capillaries and fine lymphatic vessels called lacteals close to its surface.

Explanation:

There, the villi and the microvilli increase intestinal absorptive surface area approximately 40-fold and 600-fold, respectively, providing exceptionally efficient absorption of nutrients in the lumen. There are also enzymes (enterocyte digestive enzyme) on the surface for digestion
