A population of insects is sprayed with a new insecticide. Most of the

1 answer:

4 0

Answer: This shows that over time, some insects can become "pesticide-resistant" meaning that pesticides don't affect them anymore. And this only happens every few generations. Therefore, each generation is being naturally selected and accumulating variations that make them resist the chemicals. This shows that each cockroach's genes are changing to give them variation from the rest of the population.

Need a hypothesis for “How are proteins built from RNA”

Dima020 [189]

Hi!

Hypothesis:

Proteins are built from the translation of messenger RNA (mRNA) molecules

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).

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

ATGCGCAGTTATTGCGAT

The corresponding RNA sequence will be:

UACGCGUCAAUAACGCUA (complementary with U instead of T)

<h3>From RNA to Protein</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 UCA, the tRNA will allocate a Serine residue.

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!

Which statement is true for all prokaryotic and eukaryotic organisms?

horrorfan [7]

Answer: Both types of the organism assemble proteins

Explanation:

The statement that is true for all the prokaryotes and eukaryotic organism. both of the organism assemble protein through the process of transcription and translation.

Both type of the organism use different-different machinery but assemble protein by transcription and translation.

Transcription and translation is the process by which the protein synthesis takes place.

___________ It is a process in producing garden soil that will remove unwanted particles

vampirchik [111]

Answer:

Adding organic matter or growing cover crops

Explanation:

Adding organic matter or growing cover crops in the form of aged manure to the soil is a process used in producing garden soil and this is because not only will the compost make the land good and fertile it will also makes the garden soil friable unlike the application of fertilizer

Deposition is a

mixer [17]

Answer: D) constructive process

Explanation:

Deposition is the geological process in which sediments, soil and rocks are added to a landform or land mass. Wind, ice, water, and gravity transport previously weathered surface material, which, at the loss of enough kinetic energy in the fluid, is deposited, building up layers of sediment.

Mepolizumab and reslizumab improve asthma control by binding to

kicyunya [14]

Interleukin-5 (IL-5). IL-5 is responsible for the recruitment and maturation of eosinophil. Eosinophils on the other hand are majorly involved in the inflammatory response in asthma- characterised by narrowing of the airways. Mepolizumab and reslizumab are, therefore, anti-IL-5
