Answer:
126 mm Hg
Explanation:
the percentage by volume of oxygen in the air is 21%. Therefore it also contributes to the 21% of the total barometric pressure of the air.
Now, 21% of 600 mm Hg
=21/100*600= 126mm Hg
therefore The partial pressure of O2in Antonito’s air is approximately is 126 mm of Hg.
They are both biotic factors because they affect living organisms. The abiotic factor a lion and deer needs is water because they need to stay hydrated but water is not living . Deers eat plants, plants are known as biotic factors too. And lions eat their prey which are living animals and once they are preyed upon they are still considered biotic because they were once living before getting consumed by the lion.
If i'm not mistaken i believe it would be a peer review.hope this helps
All forms of RNA are intermediate molecules that are fabricated within DNA to perform cellular functions.
mRNA - messenger RNA carries selected portions of DNA used to fabricate polypeptides used to fabricate amino acids for protein.
tRNA - transfer RNA is comprised of select genetic code and transfers amino acids to ribosomes for assembly
rRNA - ribosomal RNA is comprised of select genetic code and makes the ribosomes
RNA is highly mutatable, highly reactive, non-reproductive, and highly specialized metabolically, and consequently totally unsuitable for consideration of any pre-DNA senario being posited for the origin of life.
Vitamin D plays a vital role in the regulation of calcium deposits and maintenance of the phosphorous levels in the blood which are two elements that are significantly important for maintaining healthy bones.
The human body needs vitamin D to absorb calcium in the intestines and to recover calcium that would otherwise be excreted through the kidneys. It also essential for the development and strengthening of bones and it blocks the release of parathyroid hormones.
The answer would be letter E. None of the above
