Which RNA molecule is involved in translating a short sequence of RNA into an amino acid, acting like a molecular Rosetta stone?
oee [108]

Given what we know about the translation process, we can confirm that the RNA in question that aids in the process of translating a short sequence of RNA into an amino acid is mRNA.

mRNA is referred to as messenger RNA. This RNA molecule acts as just that, a messenger carrying the necessary code to create amino acids and therefore, proteins. This messenger binds itself to <em><u>the </u></em><em><u>ribosomes</u></em><em><u> of a </u></em><em><u>cell</u></em>, which are in charge of reading the code,<em><u> one </u></em><em><u>codon </u></em><em><u>at a time,</u></em> and <u>chaining together the corresponding </u><u>amino acids</u><u>. </u>

Based on your prior knowledge, make a claim about the factors that cause inherited genetic variations within populations. Also m
solniwko [45]

Answer AND Explanation:

<u>FACTORS THAT CAUSE GENETIC VARIATIONS</u>

  1. Crossing over. At the chiasmata during prophase I of meiosis, breakage may occur and exchange of genetic information may take place. New gene combinations which result in variations.
  2. Independent assortment. The arrangement of homologous chromosomes at the equator of the spindle during metaphase of the first meiotic division is random. These homologous chromosomes segregate into different daughter cells which contain different genetic combinations which brings about variation
  3. Fertilisation permits parental genes to be brought together in different combinations. This is the cause of variations in members of the same family.
  4. Mutation is the spontaneous change in the genetic makeup of an organism. These changes may be inherited by the offspring therefore beginning variation.

Which energy transformation occurs in the core of a nuclear reactor?
Andrei [34K]

It is a fact that nuclear energy is converted into thermal energy in the core of a nuclear reactor. This is because it is part of a power plant fission act, where nuclear energy heats up water in a nearby vicinity.

An example of a pioneer species is
cricket20 [7]

The right answer is Lichen.

In ecology, a pioneer species is one of the first forms of life that colonize or recolonize a given ecological area.

Lichens are composite organisms resulting from a symbiosis between at least one heterotrophic fungus called mycobionte, representing 90% of all, and microscopic cells with chlorophyll (green algae or cyanobacteria autotrophic for carbon) called "photobionts" .
