Severe acute respiratory syndrome (SARS) is an illness caused by a coronavirus. Symptoms, including a high fever, headaches, and body aches, typically occur two to seven days after infection by the virus. This information suggests that the reproductive cycle of the SARS virus is - lysogenic, because the virus is a coronavirus. lysogenic, because the virus is a coronavirus. lysogenic, because the virus primarily affects older people. lysogenic, because the virus primarily affects older people. lytic, because the virus causes respiratory illness. lytic, because the virus causes respiratory illness. lytic, because of the quick onset of symptoms after infection.

Answers

Answer 1

Answer:

lytic, because of the quick onset of symptoms after infection

Explanation:

As seen in the question above, the SARS virus tends to develop symptoms very quickly when it is infecting a person. This speed in the development of symptoms is a characteristic of the lytic cycle, in relation to the reproductive cycle of viruses. This is because in the lytic cycle, a virus can infect many cells at once, which accelerates the development of the disease. This cycle allows the virus to use all of the cell's biological machinery to reproduce more copies of the virus. When these copies are ready, the virus causes the destruction of the host cell and the release of new viruses to other cells, where the whole process will be repeated. This is all done very quickly.

The lysogenic cycle does not cause the rapid infection of thousands of cells, since it is necessary that there is an adaptation between the DNA of the cell and the DNA of the virus. This slows down the infection process and, therefore, symptoms appear more slowly.

What is the main difference between primary succession and secondary succession?

Answers

Answer:

Primary succession in the first initial establishment of an ecosystem on a new layer of terrain (usually rock), whereas secondary succession is a re-establishment of an ecosystem OR simply any establishment of an ecosystem on a rock which was previously inhabited.

Explanation:

Primary succession is the very first establishment of an ecosystem on a new layer of terrain (usually rock) which was previously uninhabited by living organisms. Secondary succession can be thought of as a re-establishment of ecosystems on a terrain/rock which was previously inhabited but is no longer due to an ecological or environmental disruption.

Hope this helped!

Answer:

Primary succession is the progress of plants growing on bare lands, like a bulldozed area, a landslide, or even a solid rock. (Or a volcano.)

On the rock, lichens start, make a little soil, mosses start in the soil, make a little more, Spikemoss (a vascular plant) starts, traps and makes more soil, making a place for dry land plants, which trap and make more soil, eventually, after a very long time, giving rise to a mature forest over rock. The only way to tell that rock is the substrate is the forest composition

Secondary is from a place that has had a forest, and is either burned, farmed, or cut. Plants start very quickly from seeds, roots, tubers, and reforestation can take as little as 20 years, and maturity as little as 75.

SHORT ANSWER QUESTION: Include a Claim, Evidence, Explanation, and Conclusion for full credit. Rubric is include at top of quiz.

In the past, fifty percent of jaguars in the Amazon jungle had large strong jaws and fifty percent had weak jaws. There was a change in their environment leaving only hard-shelled reptiles like turtles available for the jaguars to eat. Below is a graph showing the allele frequency in the population of jaguars over the next 5 generations.

Construct an argument based on evidence to determine which allele represents the large strong jaws and which allele represents the weak jaws.

Answers

Answer:

Allele G represents the strong jaw, and allele g represents the weak jaw. This is because as the generations go by, allele G’s population increases, but allele g’s population decreases. If hard shelled animals are the only foods available to them, you would need a strong jaw to eat them. This means that allele g wouldn’t be able to eat these reptiles, so their population would decrease from lack of food.

Explanation:

describe a specific exmaple of postive action that reduce human imapct on land?

Answers

Answer:

Human activities contribute to climate change by causing changes in Earth’s atmosphere in the amounts of greenhouse gases, aerosols (small particles), and cloudiness. The largest known contribution comes from the burning of fossil fuels, which releases carbon dioxide gas to the atmosphere. Greenhouse gases and aerosols affect climate by altering incoming solar radiation and out-going infrared (thermal) radiation that are part of Earth’s energy balance. Changing the atmospheric abundance or properties of these gases and particles can lead to a warming or cooling of the climate system. Since the start of the industrial era (about 1750), the overall effect of human activities on climate has been a warming influence. The human impact on climate during this era greatly exceeds that due to known changes in natural processes, such as solar changes and volcanic eruptions.

In a population with 100 rabbits there are 16 that are albino, with two
recessive genes for albinism. In this population, what is the gene
frequency for the albino allele?
16
16
0.4
0.84

Answers

Answer:

The gene frequency for the albino allele is 16%.

Explanation:

Given that in a population with 100 rabbits there are 16 that are albino, with two recessive genes for albinism, to determine, in this population, what is the gene frequency for the albino allele, the following calculation must be performed:

16/100 = X

0.16 = X

1 = 100

0.16 = X

0.16 x 100 = X

16 = X

Therefore, the gene frequency for the albino allele is 16%.

A scientific study demonstrated that rat mothering behavior impacts the stress response in their pups. Rats that were born and grew up with attentive mothers showed low activation of stress-response genes later in life, while rats with inattentive mothers had high activation of stress-response genes in the same situation. An additional study that swapped the pups at birth (i.e., rats born to inattentive mothers grew up with attentive mothers and vice versa) showed the same positive effect of attentive mothering. How do genetics and/or epigenetics explain the results of this study

Answers

Answer and Explanation:

Regarding genetics, the results of the study show that the mother's genetic material does not influence the behavior of rats in times of stress or in the biological responses of rats to these stressful moments. This is because the mice inherited their mothers' genes, but did not show the same results in a stressful situation when they were raised with different mothers.

Regarding epigenetics, however, we can see that the mothers' behavior in relation to the care of rats managed to provoke epigenetic changes that prevented or stimulated the expression of genes linked to stress, in these rats. The rats that were raised with attentive mothers showed a low expression of stress-linked genes, regardless of the biological mother they had. In addition, it is possible to notice that this modification is permanent, since the rats presented this same type of response throughout their lives.
