Why do Mars and Mercury have many more craters compared to Venus?

Biology
1 answer:
Marina86 [1]3 years ago
4 0

Answer:

They have a thinner atmosphere.

Explanation:

Venus has a very dense atmosphere compared to Mars and Mercury. This causes many small meteorites and asteroids to break apart before they reach the surface. Thus, Venus has fewer craters than Mars and Mercury.

When a body is buried directly in the soil, both toxic chemical products of decomposition and nutrient-rich decomposition fluids
ValentinkaMS [17]

Cadaver Decomposition Island

-  When a body is buried directly in the soil, then it is subject to decomposition by insects and microorganisms. 

<span>- </span>During this process, a self-digestion of the cells occurs as well as anaerobic decomposition of animal proteins resulting in a release of various chemical components.

<span>- </span>This nutrient-rich fluid is trapped in the soil matrix for a long period of time resulting in the formation of Cadaver Decomposition Island

<span>- The formation of Cadaver Decomposition Island is associated with increased microbial biomass and activity.</span>

In order to make a protein the messenge on DNA must be converted to what?
Soloha48 [4]

Explanation:

-mRNA or messenger RNA

DNA wound into chromosomes within the nucleus is unwound, unzipped and read by enzymes in a complex series of steps known as transcription. The message on DNA, called genes is copied by RNA polymerase, to form mRNA complementary sequence to that of the DNA strand.

Further Explanation:

Nucleic acids are comprised of smaller units called nucleotides and function as storage for the body’s genetic information. These monomers include ribonucleic acid (RNA) or deoxyribonucleic acid (DNA). They differ from other macromolecules since they don’t provide the body with energy. They exist solely to encode and protein synthesis.

  • Basic makeup: C, H, O, P; they contain phosphate group 5 carbon sugar, these nitrogen bases which may contain single to double bond ring.

Nucleic acids like DNA stores all of an organism’s genetic information. Nucleic acid molecules comprise the nitrogenous bases Guanine, Adenine, Cytosine and Thymine. Conversely, RNA nucleotides are Adenine, Guanine, Cysteine and Uracil. These pair up as base pairs due to their varied structure- largely influenced by the location of N molecule.  

In certain combinations, these bases form codons which act as instructions for protein synthesis. Codons are three nucleotide bases encoding an amino acid or signal at the beginning or end of protein synthesis.

RNA codons determine certain amino acids, so the order in which the bases occur within in the codon sequence designates which amino acid is to be made bus with the four RNA nucleotides (Adenine, Guanine, Cysteine and Uracil). Up to 64 codons (with 3 as stop codons) determine amino acid synthesis. The stop codons ( UAG UGA UAA) terminate amino acid/ protein synthesis while the start codon AUG begins protein synthesis.

Thus, these contribute to the broad diversity of living organisms, as varied combinations of these 64 codons can produce many proteins which can be organized into cells, tissues and organisms.
