Answer:

Figure 3

Explanation:

A mixture is a substance made up of two or more different kind of atoms arranged in such a way that they are not chemically linked or joined. This accounts for the reason a mixture can be separated easily. In the figures attached as an image in this question:

- Figure 1 represents an element because it is made up of only hydrogen atoms chemically bonded together to form a molecule.

- Figure 2 represents a compound because it contains hydrogen and carbon atoms chemically joined together.

- Figure 3 represents a MIXTURE because it contains the oxygen and carbon atoms, which are not chemically joined to one another. As seen in the image, the oxygen atoms are not joined to the carbon atoms.

- Figure 4 represents a compound because it contains oxygen and hydrogen atoms chemically bonded together.

In eukaryotic gene regulation, RNA interference occurs through:
Anit [1.1K]

Answer:

B. the action of microRNAs that block translation of specific mRNA molecule

C. the action of RNA–protein complexes that degrade the regulatory proteins responsible for initiating transcription.

Explanation:

RNA interference occurs what RNA prevent the translation of some gene this is done by neutralizing target mRNA molecule. It suppresses the effects of some desires genes through its action.

MicroRNA and small interfering RNA (miRNA and siRNA) are the major RNA that controls interference. siRNA and miRNA prevent translation by directing some enzmes complexes to denature the mRNA molecule needed for translation. They intiate post transcriptional splicing.

RNA interference is found in eukaryote and some animals and its initiated by enzyme Dicer that inhibits translation by degrading the enzymes action.

<h2>Mutation & genetic drift</h2>

Explanation:

  • A mutation is characterized as a lasting change to the DNA succession in a quality. This change moves the hereditary message conveyed by the quality and can modify the amino corrosive arrangement of the protein the quality encodes. This implies future cells created by the quality will just convey a specific characteristic.  
  • Genetic Drift is the change in the hereditary structure of a populace after some time because of possibility or irregular occasions. In instances of hereditary float, for example, catastrophic events or periods of irregular climate, the age that makes due to repeat won't really be the fittest, yet the most fortunate. Hereditary float doesn't allude to a particular change in hereditary cells, rather to arbitrary events that impact a population's genetic makeup.
  • Hence, the right answer of the fill up the blank is "mutation and genetic drift".
