Scientists today are studying tidal power as an alternative energy source for generating electricity. Some scientists conclude that tidal power is a good alternative source of energy because it uses a natural process, does not rely on fossil fuels, and does not release greenhouse gases. These scientists recommend building tidal power plants around the United States in locations with high tidal power potential. Other scientists conclude that tidal power is not a good alternative energy source because tidal power plants can negatively impact the surrounding ecosystem by killing marine animals, restricting fish migration, reducing the natural flow of water, and causing silt buildup in waterways. These scientists recommend not building tidal power plants in U.S. waterways. Both conclusions are based on valid data and scientific reasoning. How can both conclusions be valid?

Answers

Answer 1

Answer:

See the answer below

Explanation:

Both conclusions can be valid because they are based on valid data and scientific reasoning.

In order for a data to be valid in making a conclusion, such data must have been collected through a scientific experiment that is devoid of subjectivism. In order words, the data must have been objectively collected via standard experimental procedures.

Once data have been collected, they are analyzed and used to make valid conclusions based on the hypothesis which must have been made earlier before the experiment.

Conclusions made from standard experimental procedures and scientific reasonings are valid and such experiments are reproducible.

Hence, as long as the data from which the conclusions were made can be reproduced through the same experiments, the conclusions are valid.

A retrovirus is a type of RNA virus that inserts a clone of its genome into the DNA of a host cell that it invades. An example of a retrovirus would be HIV.

Hope this helps! :)

Explanation:

A retrovirus is a specific kind of RNA virus that, when it infects a host cell, will insert a clone of its genome into the DNA of the host cell. HIV is an example of a retrovirus that may infect humans.

What is a retrovirus?

A kind of RNA virus known as a retrovirus copies its genome into the DNA of the host cell it invades. HIV is a prime example of a retrovirus.

A virus that employs RNA as its genetic material is referred to as a retrovirus. When a cell becomes infected with a retrovirus, the retroviral RNA is converted to retroviral DNA, which is then inserted into the DNA of the host cell.

Acute retroviral syndrome symptoms, which include headache, nausea, diarrhoea, and body pains, are comparable to those of the flu and go away on their own in a few of weeks. A person who has acute retroviral syndrome may no longer have any symptoms, yet they are nonetheless HIV-positive and remain contagious.

Describe the transport properties of the loop of Henle and explain the interactions between the ascending and descending limbs

Answers

Answer:

The loop of henle is a part of the renal functional unit.

This handle has an ascending part and a descending part.

In the descending loop, the urine that is formed inside enters a hypotonia, since a large amount of water is absorbed and the concentrations of solutes in the urine decrease, thus generating a hypoosmolar solution, that is, with less molarity.

In the ascending loop of henle, the opposite arises, ionic channels appear that increase the concentration of solutes, this is how the urine that runs through the interior of the ascending loop of henle becomes hyperosmolar.

Hyperosmolarity is the increase in concentrations of solutes, and the increase in molarity of the solution, which in this case would be urine.

Explanation:

A very important fact is that urea is absorbed in the ascending henle loop.

The force of a muscle contraction is higher when the muscle is stimulated every 0.5 secs than when stimulated with the same voltage every 0.05 seconds.

a. True
b. False

Answers

Answer:

b. False

Explanation:

Increasing the frequency of muscle stimulation causes wave summation to occur, which causes an overlap of muscle twitch. When this muscle summation happens, the force generated in the muscle increases. This means that stimulating the muscle every 0.5 seconds will generate less muscle contraction force than when stimulated every 0.05 seconds  

By 1884, extensive hunting reduced the number of Northern elephant seals to fewer than 100. The extremely limited genetic variation in these seals is consistent with which genetic effect?

Answers

Answer:

Genetic drift, specifically the Bottleneck effect.

Explanation:

Genetic drift is an evolutionary mechanism in which the allelic frequencies in a population change through many generations. Its effects are harder in a small-sized population, meaning that this effect is inversely proportional to the population size. Genetic drift results in some alleles loss, even those that are beneficial for the population, and the fixation of some other alleles by an increase in their frequencies. The final consequence is to randomly fixate one of the alleles. Low-frequency alleles are the most likely to be lost. Genetic drift results in a loss of genetic variability within a population.  

Genetic drift has important effects on a population when this last one reduces its size dramatically because of a disaster -bottleneck effect- or because of a population split -founder effect-.

The bottleneck effect is a special case of genetic drift, which is most likely to affect smaller populations.  In the exposed example, extensive hunting reduced the number of Northern elephant seals, reducing the number of individuals to fewer than 100. This population experienced one or many generations of very small size since these animals were affected by hunting. As the survivors did not have the whole genetic pool of the original population,  the population size might have recovered, but the genetic pool might have not.

The removal of sections of RNA, called introns, occur at which regulation step in eukaryotic cells? (1 point)
o mRNA life span
O post-translation
O RNA processing
ochromatin remodeling

Answers

Answer:

post-translation

Explanation:

When a eukaryotic gene is transcribed in the nucleus, the primary transcript (freshly made RNA molecule) isn't yet considered a messenger RNA. Instead, it's an "immature" molecule called a pre-mRNA.

The pre-mRNA has to go through some modifications to become a mature mRNA molecule that can leave the nucleus and be translated. These include splicing, capping, and addition of a poly-A tail, all of which can potentially be regulated – sped up, slowed down, or altered to result in a different product.

Most pre-mRNA molecules have sections that are removed from the molecule, called introns, and sections that are linked or together to make the final mRNA, called exons. This process is called splicing.

In the process of alternative splicing, different portions of an mRNA can be selected for use as exons. This allows either of two (or more) mRNA molecules to be made from one pre-mRNA.

Answer:

RNA processing

Explanation:

RNA processing. Splicing, capping, and addition of a poly-A tail to an RNA molecule can be regulated, and so can exit from the nucleus. Different mRNAs may be made from the same pre-mRNA by alternative splicing.

Answers

Answer: Option E.

All of these are used by parietal cells.

Explanation:

Parietal cells are found in the stomach and they produced gastric acid(Hcl)..

HCl is produced when water mixed with carbondioxide in the parietal cell to produced carbonic acid which is catalyses by carbonic anhydrase. The carbonic acid then dissociates into hydrogen ion and carbonate ion.

Parietal cell produce HCl due to histamine (via H2 receptors), acetylcholine (M3 receptors) and gastrin (gastrin receptors).

Therefore it uses channels, pumps, antiporter.
