The molar mass of an atom is simply the mass of one mole of its identical atoms. However, most of the chemical elements are found on earth not as one isotope but as a mixture of isotopes, so the atoms of one element do not all have the same mass.

For many of the chemical elements there are several known isotopes. Isotopes are atoms with different atomic masses which have the same atomic number. The atoms of different isotopes are atoms of the same chemical element; they differ in the number of neutrons in the nucleus.

Korvikt [17]

Answer:

The ability of species of living beings to overproduce offspring

Explanation:

Darwin proposed that species have the ability to produce offspring at a rate that could cause a geometric increase in the population size. This is called biotic potential. The overproduction of offspring causes intraspecific competition for the limited available resources. Darwin reasoned that the overproduction of progeny leads to a struggle for existence between the individuals of a population. He observed that the struggle for existence does not allow the population size of species to grow geometrically.

g In transcription, the 3'-hydroxyl group of the growing RNA strand: Group of answer choices NONE OF THESE binds to the 5' ribos

Tatiana [17]

Answer:

attacks the outermost phosphorous group of the incoming nucleotide.

Explanation:

Transcription is the biological process where RNA is formed. As you may already know, RNA is an extremely important nucleic acid for genetic processes and the production of proteins. The transcription has three steps that are called start, elongation and end. In the elongation phase, the RNA strand is growing, at this time, RNA polymerase, which is the enzyme responsible for RNA elaboration, places the nucleotides, in the RNA strand, in the 5' - 3' direction. This enzyme causes the hydroxyl, which makes up the nucleotide at the 3' end of the forming RNA, to attack the phosphorus present in the incoming ribonucleotide.

Imagine a species with three loci thought to be on the same chromosome. The recombination rate between locus A and locus B is 35

Vesnalui [34]

Answer:

<h2>Recombination rate or recombination frequency between locus A and locus C is either 2% or 50%. </h2>

Explanation:

As given,

Recombination frequency between locus A and B is 35%, means that the distance between A and B is 35 cM.

Recombination frequency between locus B and C is 33% , means the distance between B and C is 33 cM.

Therefore, if the locus C is present between A and B, then the recombination frequency between A and C would be 2%

A-----C ----------B

A---C= 2%

A----B= 35%

B---C= 33%

So, here the recombination frequency between A and C is 2%, means their distance is 2 cM.

If the locus C is as, A---35---B--33----C ; A-----B------C

A-----B= 35%

B------C= 33%

A-----C= 33+35= 68%

As rule, maximum frequency can not exceed 50%, as here the Recombination frequency between A and C = 50%.
