Secrete 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. SARS is more serious in elderly patients. This information suggests that the reproductive cycle of the SARS virus is –
a. Lysogenic, because the virus is a coronavirus
b. Lytic, because the virus causes respiratory illness
c. Lysogenic, because the virus primarily affects older people
d. Lytic, because of the quick onset of symptoms after infection
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.

waves where the particels travel at right angles to the driction of the wave itself
Answer:
Transverse wave
Explanation:
A transverse wave is a wave in which particles of the medium vibrate at right angles, or perpendicular, to the direction that the wave travels. Another example of a transverse wave is the wave that passes through a rope when you shake one end of the rope up and down, as seen in the figure below.

What is the reflex arc?The reflex arc refers to the sequence of events since the body receives external stimuli until it reacts to it.
In general terms,
1. a stimulus of varying nature reaches the body,
2. the peripheric nervous system -PNS- receives the stimulus and sends this information to the central nervous system -CNS-.
3. The CNS processes the information and sends another signal as a response to the stimulus.
This mechanism is known as the reflex arc, and it is composed of five elements,
- Receptors,
- Three types of neurons,
Afferent or sensorial neuronsInterneuronsEfferent or motor neurons- Effectors.

geologists describe the rock cycle as ' nature's recycling system' what does it mean? please help
Answer:
The Rock Cycle is Earth's great recycling process where igneous, metamorphic, and sedimentary rocks can all be derived from and form one another.Older rocks are destroyed by weathering processes and the remains are recycled into new rocks. This cycle from old rocks to new rocks is called the rock cycle. The interaction between the tectonic and the hydrologic systems causes constant recycling of the materials of the Earth's crust.

Explain why water is essential for the process of seed germination.
Answer:
Water is an important external factor that triggers the process of germination. The seeds absorb the moisture and swells up. Then the hydrolytic enzymes become active which will break down the reserve food materials so as to make it available for the growth of embryo resulting in the germination.
Explanation:
water is essential for the process of seed germination because it helps by providing necessary hydration for the vital activities for protoplasm, provide dissolved oxygen for the growing embryo softens the coats and increase the seed permeability
