Because there are three different possible reading frames in a messenger RNA (mRNA) molecule, most mRNAs can be translated in a
Dmitry [639]

Answer:

False

Explanation:

In the genetic code, each triplet of nucleotides (i.e., each codon) determines one specific amino acid or one-stop codon. The genetic code is not overlapping, which means that the same letter in the genetic code (nucleotide) cannot be used for two different codons. There are 64 possible combinations of triplets of nucleotides, 61 of them determine amino acids, while three triplets determine stop codons (UAG, UAA, and UGA) that indicate the termination of translation. Moreover, the genetic code is also degenerate, which means that one amino acid can be coded by more than one codon.

<h2>Answer:</h2>

Blood Is A Heterogeneous mixture.

<h2>Explanation:</h2>

Heterogeneous mixture is a mixture that is made up of different substance that remains physically separated which means the cell organelles (Red blood cells, white blood cells, platelets etc.)present in blood does not mix completely and hence get precipitated after kept still for a while.

There are three ways to identify a Heterogeneous mixture.

  1. It has chunks of stuff that you are able to see with your eyes.
  2. It appears cloudy(blur).
  3. After a while, the substance will separate into layers at settle at the bottom(gets precipitated).

Result: Blood is a Heterogeneous mixture

Vadim26 [7]

Answer;

-Bone tissue becoming stronger.

The mechanical stress applied to bones during moderate physical exercise leads to bone tissue becoming stronger.

Explanation;

-Bones and muscles both become stronger when muscles push and tug against bones during physical activity.Swimming and bicycling are not weight-bearing activities, so they do not directly help build bones. But swimming and bicycling do help build strong muscles, and having strong muscles helps build strong bones.

-Weight-bearing physical activity causes new bone tissue to form, and this makes bones stronger. This kind of physical activity also makes muscles stronger. Bones and muscles both become stronger when muscles push and tug against bones during physical activity.

Sedbober [7]

Answer:

This is an example of "Disruptive selection".

Explanation:

<em>Disruptive selection</em> occurs when <em>selective pressure</em> <em>favor homozygous</em>. In equilibrium, <em>the two alleles might be present or one of them might be lost</em>. If an environment has two extremes, then in these environments, both alleles are presented in homozygous.  

The disruptive selection causes an <em>increase</em> in the two types of <em>extreme phenotypes over the intermediate forms</em>. Limits between one extreme and the other are frequently very sharped. Individuals belonging to one phenotype can not live in the same area as individuals belonging to the other phenotype, due to the traits differences between them, competition, or predation.

Populations show two favored extreme phenotypes and a few individuals in the middle. Individuals who survive best are the ones who have traits on the <u>extremes forms</u>.  Individuals in <u>the middle</u> are not successful at survival or reproduction.

<em>Color</em> is very important when it comes to <em>camouflage</em>. Dark green caterpillars that live in dark foliage and light green caterpillars that live in light foliage can <em>hide from predators</em> more effectively and will live the longest. Intermediate colored green caterpillars that don't camouflage or blend into either will be eaten more quickly.
