As populations are the smallest unit that actually evolves, it is reasonable to call them the "unit of evolution"

As populations are the smallest unit that actually evolves, it is reasonable to call them the "unit of evolution". Individuals are usually called the "unit of selection" as whether an individual lives/dies/reproduces changes the genetic composition of the next generation.

Hope this helped!

BTW can I have brainliest?

A) In how many cases in the genetic code would you fail to know the amino acid specified by a codon if you knew only the first t

Vesna [10]

Answer:

a) 28 cases

b) 3 cases

Explanation:

a) From the table of genetic codes, there are 28 codons that specify more than one amino acid assuming only the first two nucleotides are considered. In these cases, one cannot outrightly specify the amino acid the genetic codes are coding for without knowing the last nucleotide of the codes. For example, UU can be for Phenylalanine or Leucine, CA can be for Histidine or Glutamine, etc.

b) From the table of genetic codes, the first two nucleotides of Arginine can be either of CG or AG, that of Serine can be either of UC or AG while that Leucine can be either of CU or UU. Only in these 3 cases would one fail to know which are the first two nucleotides assuming the name of the amino acids are given.

See the attached image for the genetic code.

The Sun's electromagnetic radiation is produced by

Aleks04 [339]

Answer:

-Changing electric and magnetic fields 

Explanation:

Electromagnetic forces from the sun are formed when electric charges change their potential energy.

This electromagnetic forces are produced at different wavelengths across across the EM spectrum.

The sun also emits x-rays during solar flares.

The absorbed energy causes one or more electrons to change their location and get replaced by absorbed energy.
