Answer: 2, 4 and 5.
Explanation:
Human system are made of various organs which in turn are made up of various tissues which in turn are made up of various cells. Cells are therefore much more numerous than systems.
As already mentioned, organs are made up of tissues which are made up of cells so statement 4 is right.
As systems are made up of various organs working together, they are more complex than the individual organs. For instance, the Muscular system is more complex than the triceps or bicep muscles.

Answer:
The envelope come from the host cell membrane as the virus leaves the host cell
Explanation:
A virus is an organism that is incapable of replicating on its own without infecting a living host. A virus consists of a genetic material (DNA or RNA) , a protein coat called CAPSID, and sometimes some viruses possess an envelope, which is an outer covering or enclosure. Viruses that possess this envelope are referred to as ENVELOPED VIRUS.
The virus lacks the ability to produce any structure, hence, they gain this envelope made of phospholipid from the cell membrane of the host they infect. During the infection cycle of a virus, a process called budding enables a portion of the host's plasma membrane to cover or encapsulate the virion cells, hence, making them enveloped in the process.
Answer: d) lightheadedness or unconscious episodes.
Explanation:
There are several ways the body responds to stress but one method used by psychologists to measure this response is Hans Selye's general adaptation syndrome. This occurs in 3 stages:
1. The alarm reaction. This occurs when the stressor is first presented resulting in the RELEASE OF HORMONES from the adrenal gland into the blood stream. The hormone in turn cause sympathetic nervous system activation and increase energy levels, INCREASE RESPIRATION, increase muscle tension, reduce sensitivity to pain, slow down the digestive system, and cause a RISE IN BLOOD PRESSURE.
2. The stage of resistance- this occurs till the stress is removed.
3. The stage of exhaustion
