Answer:

C. Placental mammals

Explanation:

The placentals are the largest group of mammals, totally dominating the class and terrestrial habitats.

Amnium, the fluid that protects the embryo from adhesions and shocks, is installed in the female's uterus for development with the help of a placenta that provides fixation and nutrients.

This breeding method, although producing a smaller number of offspring per pregnancy, has a high success rate, allowing greater chances of survival to offspring.

Which phrase describes a density-independent limiting factor that can affect
Alenkasestr [34]

The phrase dune erosion by ocean water along a shoreline best describes a density-independent limiting factor that can affect ecosystem stability (Option B).

<h3>What is a density-independent limiting factor?</h3>

A density-independent limiting factor can be defined as any factor in a given ecosystem that may alter the homeostasis of the population that lives in a given geographic area.

These factors (density-independent limiting factors) are generally abiotic factors such as hurricanes, extreme temperature conditions, the presence of contaminants in the air that hamper life in a given area, etc.

Conversely, density-dependent limiting factors are biotic factors such as competitive species that alter the development of another population.

Therefore, with this data, we can see that a density-independent limiting factor is any abiotic condition that may alter the life of a population in a give geographic area and thus alter the homeostasis of the whole ecosystem.

Severe acute respiratory syndrome (SARS) is an illness caused by a coronavirus. Symptoms, including a high fever, headaches, and
monitta

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.

In the absence of oxygen, a yeast cell undergoes fermentation and uses 100 molecules of glucose. How much net ATP will be genera
vredina [299]

Answer:

200 ATP molecules

Explanation:

Yeast is a fungus that undergoes fermentation instead of cellular respiration when there is an absence of oxygen. In the fermentation process undergone by yeast, which produces an alcohol as product (alcohol fermentation), two (2) ATP molecules are produced as net ATP.

However, if a yeast cell undergoes fermentation and uses 100 molecules of glucose, the yeast cell will generate a net ATP of 2 × 100 molecules = 200 molecules.
