Answer:

The correct answer would be "They release the carbon that remains in the bodies of dead organisms".

Decomposers are heterotrophic organisms which get their nutrition by breaking down remains of dead plants and animals. The process of breaking down the dead remains of plants and animals is termed as decomposition.

By doing so, they play an important role in an ecosystem. They help in recycling of the nutrients such as carbon and nitrogen in an ecosystem. They return these nutrients to the soil from where plants can reuse the same.

In addition, they help in removing or cleaning the dead matter and waste material from the ecosystem.

Need a hypothesis for “How are proteins built from RNA”
Dima020 [189]

Hi!


Hypothesis:

<em>Proteins are built from the translation of messenger RNA (mRNA) molecules</em>


RNA, or ribonucleic acid, is a structure that is similar to DNA, except that it exists as a single strand, consists of a ribose sugar instead of a deoxyribose sugar and has the base uracil (U) instead of thyamine (T).


<h3><u>From DNA to RNA</u></h3>

RNA is generated through transcription of the DNA molecule, resulting in a <em>complementary </em>molecule of the template DNA strand. For instance, if the sequence of the DNA was:

ATGCGCAGTTATTGCGAT

The corresponding RNA sequence will be:

UACGCGUCAAUAACGCUA    <em>(complementary with U instead of T)</em>


<h3><u>From RNA to Protein</u></h3>

The RNA molecule in our case is known as the mRNA. After transcription the mRNA molecule is transported to the cytoplasm, where a ribosome binds to it for another molecule to translate the sequence. This translation is mediated by an RNA molecule known as the tRNA molecule which enters the ribosome to catalyze the reaction.

These molecules identify a sequence of 3 bases (codon) and for specific codon sequences, the tRNA allocates specific amino acid. For instance, for the codon <em>UCA</em>, the tRNA will allocate a <em>Serine residue.</em>

This translation process starts at specific three base sequences, known as start codons, and terminates at specific three base sequences known as stop codons.

In this manner, a sequence of amino acids respective to the mRNA codon sequence is synthesized, and as we identify proteins as chains of amino acids that are covalently linked together through peptide bonds, we can clearly see that proteins are built directly from RNA, and indirectly from DNA.


Hope this helps!

A test cross can be used to _____.
gtnhenbr [62]

Answer: - Predict an unknown genotype of a purebred dominant plant.

Explanation:

The genetic make up of the organism is called as the genotype. It describes the form of genes or allelic forms present in the organism. A test cross is used to determine the genotype of the organism. In this cross the organism with the unknown genotype is done with that of the organism with the known genotype. It also determines the fact that the organism is either homozygous dominant or hetrozygous.

On the basis of the above description, Predict an unknown genotype of a purebred dominant plant.
