All of the above! A healthy soil ecosystem needs fungi, bacteria, and nematodes in order to properly function, especially in the aspects concerning decomposition!<span />
I would think of a unicellular organism or a plant, but I'm not too sure on this one, Just trying to help :)
Answer:
During prophase, which occurs after G2 interphase, the cell prepares to divide by tightly condensing its chromosomes and initiates mitotic spindle formation. The chromatin fibers condenses into discrete chromosomes. The nucleolus also disappears during early prophase.
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.
The two-layered sac surrounding the heart is the pericardium.
Hope this helps!
