The individual should approach the U.S. Fish and Wildlife Service’s International Affairs Program, in other to determine the regulations on moving that species internationally.

This program through coordinated efforts; protect, restore, and enhance the world’s diverse wildlife resources both domestically and internationally but with a greater focus on international species.

There are different categories of wildlife species based on their abundance and distribution. Some are regarded as foreign endangered and threatened species. And the need to protect these species is priceless.

That's why the import/export of these scarce species is regulated and restricted by laws and legislation.

For whatsoever reason, the U.S. Fish and Wildlife Service’s International Affairs Program should be consulted to determine the movement of these species.

Answer:

As the prey population increases, there is more food for predators. So, after a slight lag, the predator population increases as well. As the number of predators increases, more prey are captured.

aftershock, a smaller earthquake that occurs after a previous large earthquake, in the same area of the main shock.

Answer:

The answer is Actually True!

Explanation:

Sometimes, clusters of small earthquakes called foreshock sequences come in the days or weeks before a large earthquake. Less often, seismologists have observed a process called nucleation, where the rate of slip along a fault ramps up gradually before an earthquake. Hope this helps!!!

Answer:

Whenever a cell needs energy, it breaks the beta-gamma phosphate bond to create adenosine diphosphate (ADP) and a free phosphate molecule. Cells get energy in the form of ATP through a process called respiration, a series of chemical reactions oxidizing six-carbon glucose to form carbon dioxide.

Answer:

Chemicals in the body of a living organism is one of the many factors determined in gene expression.

Explanation:

The presence of drugs and/or chemicals in a living organism's environment, this can also influence gene expression in the organism.

Hope this helps :D Happy Holidays!

Expressivity can be impacted by a number of elements, such as genetic make-up, exposure to dangerous chemical substances, other environmental effects, and age.

The level of transcription is where the majority of control over gene expression is exerted, and this is mostly due to the fact that proteins bind to certain locations on DNA.

It is possible for environmental elements such as nutrition, temperature, oxygen levels, humidity, light cycles, and the presence of mutagens to have an effect on which of an animal's genes are expressed, which in turn has an effect on the animal's phenotype.

Explanation:

Answer:

It contains three anatomically distinct divisions: sympathetic, parasympathetic, and enteric.

Explanation:

The sympathetic nervous system (SNS) and the parasympathetic nervous system (PNS) contain both afferent and efferent fibers that provide sensory input and motor output, respectively, to the central nervous system (CNS). Generally, the SNS and PNS motor pathways consist of a two-neuron series: a preganglionic neuron with a cell body in the CNS and a postganglionic neuron with a cell body in the periphery that innervates target tissues. The enteric nervous system (ENS) is an extensive, web-like structure that is capable of function independently of the remainder of the nervous system. It contains over 100 million neurons of over 15 morphologies, greater than the sum of all other peripheral ganglia, and is chiefly responsible for the regulation of digestive processes.

It is true that when heat is supplied to one end of a long metal rod, then which spreads at once in the entire rod.

Conduction is the transfer of heat energy through collisions between neighboring atoms or molecules.

Conduction occurs more easily in solids and liquids because the particles are closer together than in gases because the particles are farther apart.

Good conductors are materials that allow electricity to easily pass through them. Bad conductors are materials that do not allow electricity to easily pass through them.

Most metals are thought to be good electrical current conductors. Copper is just one of the more common materials used in conductors. Silver, gold, and aluminum are other materials that are occasionally used as conductors.

Thus, the given statement is true.

Answer:

i think the answer is B

Explanation:

The most likely happened to the donor strain is that the transposon is active in the donor resulting in the gradual accumulation of mutations. The accumulation of mutations is promoted by the insertion of the transposon.

A donor strain is a bacterial strain that contains a mobilizable fragment of DNA called plasmid.

These strains (donor strains) exploit the transference properties of a conjugative plasmid to modify a particular recipient strain.

Transposons, also known as jumping genes, are mobile genetic elements that alter the genome of an organism by jumping and thus inserting them into genetic sequences (i.e., into protein-coding sequences).

In this case, the presence of a transposon in the donor strain affected the expression of many genes required for the donor strain in order to grow into Luria DAP Agar.

Answer:

Exons.

Explanation:

In mRNA maturation and processing, a complex called a splicesome essentially "cuts out", if you will, non-coding parts of the DNA sequence to be translated. The parts that are cut out are called "introns", and the parts that are left over that code for a protein sequence, are called "exons". Careful with the terminology. It seems counterintuitive that exons are the ones that stay (exon = exit? NO.) and introns (in, as in, stays in? NO.) are the ones that are cut out of the mature mRNA. Perhaps you can remember that the terms seem to be the opposite, that's how I remember it. Alright, good luck with all of this.
