____ 15. which excretory organ eliminates water and some chemical wastes in perspiration?
Nastasia [14]
I think the answer is skin. Skin contains sweat glands which secrete a fluid waste called sweat or perspiration; nonetheless, its primary functions are temperature control and release of pheromone. Its role as a part of the excretory is therefore minimal. Additionally, sweating also maintains the levels of salt in the body.

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.

How are the symbols written for alleles that share incomplete dominance? <br> Tysm ily ;)
kakasveta [241]
In incomplete dominance, heterozygous<span> phenotype is intermediate between two homozygous phenotypes. In this case, the symbols for alleles are capital letters. For example, allele A is responsible for red color of a flower, allele B is responsible for white color of the flower. Red flower plants have AA genotype, and white flower plants have BB genotype. By crossing plants with red flowers and white flowers, due to incomplete variance, the offspring will be heterozygozs plants (AB) with neither red nor white flowers, but pink flowers. Pink flowers have intermediate color between red and white flowers.</span>
