Which type of RNA functions as a carrier of the genetic code?
gayaneshka [121]

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.

Approximately how many gallons of water are used per year in a typical home? 1 million gallons 500,000 gallons 150,000 gallons 1
Advocard [28]

146 gallons of water

<h2>Further explanation </h2>

The human need for water (for drinking) is 8 glasses a day or about 2 liters. 1 gallon usually contains 19-20 liters. One house usually consists of 4 people <em>(father, mother, brother, sister). </em>

If one person consumes 2 liters of water, then one house will consume about 8 liters a day.

Which will take up 2 gallons in 5 days.

1 Year = 365 days

365 days : 5 days <em>(2 gallons)</em> = 73 <em>(gallon water refill frequency) </em>

73 x 2 = 146

So, within 1 year the level of gallon water consumption in an ordinary house consumes 146 gallons of water.

That is the calculation of the use of gallons for consumption, <em>not for bathing, washing, pooping, urinating, etc. </em>

GrogVix [38]
I would say immigration only.

emigration would theoretically reduce the genetic variation as unique individuals leave, but immigration would bring unique traits into circulation in an ecosystem.

I'm not super great at biogy tho so this might not be right... :)
