Some bed bugs had mutations in their genetic code which allowed them to survive the chemical pesticide and they produced chemica

lly resistant offspring. How can this be explained?

Answer:

Random mutations led to evolution of pesticide resistance genes in bed bugs.

Explanation:

Random mutations in genome of bed bug imparted them the pesticide resistance. Since the bed bugs having the mutation of pesticide resistance were able to survive under presence of pesticides, this variation was favored by natural selection. The bugs with pesticide resistance transmitted this trait to their progeny. In time, the bed bug population consisted of most of the bugs having the pesticide resistance.

In a particular woodland community, two species of rodents coexist: mice and chipmunks. Both species compete for the same kinds
scZoUnD [109]

Answer:

First, we take the owl out, the total number of mouse increases at a higher rate and the chipmunks are also decreasing in numbers. In an ideal ecosystem, both mice (lets call it "a") and chipmunks (lets call it "b") should increase since the restraining factor has been removed. But that is the opposite of what we should see. In that case, we will take the owl to be the "limiting factor" for the rodents.

Am

The rodents will have free movement and exercise their fitness over the area, competition sets in between the two species. So we see, a flourishes while b dies out. This can be viewed most predictably that a has an overall greater fitness and would easily get resources and strive readily, which influences the survival rate for 2.

Juli2301 [7.4K]

The answer is penicillin

Rheumatic fever is a disease that caused by Group A streptococcus infection. The bacteria has component that similar to the heart valve cells, makes the immune cell attack it. The drug of choice for this infection is penicillin G benzathine injection. It is one of penicillin family drug that has high prevalence of allergy reaction, so you must be aware.

Hydrolysis of which molecule is important for translation initiation, elongation, and termination?
abruzzese [7]

Answer:

D. GTP

Explanation:

Initiation of protein synthesis includes binding of mRNA to small ribosome subunit and initiation aminoacyl tRNA. The pairing of the anticodon of the initiating aminoacyl tRNA and initiation codon of mRNA requires GTP hydrolysis and marks the beginning of protein synthesis.  

Elongation stage of protein synthesis requires movement of the ribosome along the mRNA which in turn is facilitated by GTP hydrolysis. As the ribosome moves along the mRNA, the codon of mRNA bind to the respective anticodon of aminoacyl tRNA by using the energy of GTP hydrolysis. The GTPase activity of elongation factor Ef-Tu ensures the fidelity of the process.  

The release factors that recognize the stop codon and serve to mark the termination of protein synthesis use the energy of GTP hydrolysis during the process.

What part of the membrane helps chemical reactions happen?
Dvinal [7]

The membrane of an organelle or cell is comprised of proteins circulating in a phospholipid bilayer.

The proteins in membranes are the ones which can facilitate chemical reactions.
