Answer:
we called them capilary
Answer:
Capillaries
Explanation:

Scientists create models to help make sense of the natural world. Models are powerful tools that help scientists predict how things work. Models should be scientifically testable. When a model fails to predict correctly, the model must be revised or replaced. A good example of this kind of model would be one that represents an animal or plant cell as drawing to illustrate the parts of the cell.

what is located in the autonomic nervous system
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.
gene expression is determined by several factors, including
Hi! Thanks for asking your question here on Brainly!
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.
What are the factors that affect gene expression?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.

You are attempting to carry out a transposon mutagenesis experiment using the pRL27 system. The Donor strain you use was giving to you by a lab mate who has been culturing it continuously for several months. When you set up your control plates, you find that the Donor strain grows poorly on Luria DAP Agar. Your transformation efficiency is very poor for this attempt at mutageneis. What likely happened to the Donor strain
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.

A small earthquake, called a foreshock, can occur seconds to weeks before a large
earthquake.
Answer:
false
Explanation:
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!!!
how does a cell get energy from an atp molecule
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.

why did the early atmosphere not have much oxygen?
Answer:
The oxygen did not build up in the atmosphere for a long time, since it was absorbed by rocks that could be easily oxidized (rusted). To this day, most of the oxygen produced over time is locked up in the ancient "banded rock" and "red bed" rock formations found in ancient sedimentary rock.

What is conduction?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.
