A dog starts chasing Gretchen. When her brain sends a signal to her muscles to run, which neurons are at work?sensory

motor

voluntary

involuntary

Answers

Answer: The correct answer is -

motor neurons.

Explanation:

Nervous system ( that includes two branches that are central nervous system and peripheral nervous system) helps in the transfer of nerve impulses to and from the various parts of body.

Sensory neurons receive information from sensory receptors (which are stimulated through outside environment). They take this information to the CNS (central nervous system that includes brain and spinal cord), where it gets processed and interpreted (particularly in the brain).

Ultimately, Motor neurons transfers this interpreted information (from the CNS to the muscles) to the glands, muscles or various other body organs for proper action to take place.

Therefore, motor neurons carry information from the CNS to dog muscles, which alarm him to run away.

Thus, motor neurons are at work.

The zebra mussel arrived in the United States in 1985 on the ballast of a ship. Since this time, it has spread rapidly throughout the waterways of the eastern U.S. and parts of Canada. Which of the following statements is NOT true about how the waters of the United States contributed to the success of the zebra mussel? They contained an abundance of prey for the zebra mussel.
They contained toxins or pollutants that eliminated natural competitors of the zebra mussel.
They contained few or no natural predators of the zebra mussel.
They contained few or no natural species occupying the niche filled by the zebra mussel.

Answers

Answer:

They contained few or no natural species occupying the niche filled by the zebra mussel.

Explanation:

All the available options are capable of contributing to the success of the zebra mussel in the United State water.

However, it is not true that the United State water contained few or no natural species occupying the niche filled by the zebra mussel. The zebra mussel are exotic species that got into the United State water around 1991 and were able to outcompete the native species and multiply rapidly, a characteristic of an invasive species.

Abundance of prey for the zebra mussel will ensure that their population thrives due to adequate availability of food.

The presence of toxins or pollutants that eliminate natural competitors of the zebra mussel will enable their population to thrive due to lack of competition for resources, provided the toxins/pollutants are not toxic to the zebra mussels themselves.

The presence of few or no natural predator will also enables the population of zebra mussels to thrive because that is another limiting factor removed.

The answer is most likely the second choice. All answer choices could be possible, but in light of the others the second choice is far too specific, and there is no information in the prompt to even indicate that as a plausible answer choice.

As a scientist, you seek to prove that DNA is the hereditary macromolecule by replicating the Hershey-Chase experiment. You culture the lambda phage in heavy and light Cl (Cl-36 is heavy and radioactive - the most abundant is Cl-35, lighter and non-radioactive). You purify the phage from their growth media and infect the E. coli, where will you detect radioactivity?Select one:
a. Within the E. coli pellet as the DNA has entered the bacterial cells.
b. On the E. coli cell surface (or phage fraction), as part of the phage protein coat.
c. In the supernatent (free liquid) of your test tube
d. Both A and B
e. None of the above
Why is the answer none of the above? Why cant the radioactivity be detected?

Answers

Answer:

The correct answer is option e. "None of the above".

Explanation:

The Hershey-Chase experiment helped to prove that DNA was the genetic material, by specifically labeling the DNA material of a bacteriophage with phosphorus-32. In this experiment the lambda phage is labeled with heavy and light Cl. CI-36, the one that is heavy and radioactive, corresponds to Chlorine-36. Chlorine is not an element found in DNA such as phosphorus, therefore lambda DNA will not be labeled and no radioactivity will be detected.

What kind of molecule is formed when many disaccharide molecules are combined?

Answers

Answer:

Polysaccharide.

Explanation:

Disaccharide is formed by the combination of two monosaccharide sugars. Fructose is a disaccharide formed by the glycosidic linkage between glucose and fructose.

Polysaccharide are the polymers of many sugars unit linked through glycosidic bonds. When many disaccharide molecule combine together they form polysaccharides. Starch is a polymer of alpha glucose units.

Polysaccharide, which is the polymer of a carbohydrate.
