Explanation:
Immunity is the ability of an animal to resist infection.
There are two types of immunity in the body; INNATE OR INHERITED IMMUNITY AND ACQUIRED IMMUNITY. Inherited immunity it is the type of immunity that one is born with. It is passed from parent to offspring.
Acquired immunity is immunity to particular infections that is not inherited but has developed in the animal's life as it interacts with its environment. Acquired immunity can develop naturally in which case it is called NATURAL ACQUIRED IMMUNITY OR ARTIFICALLY.
ACTIVE IMMUNITY is the form of acquired immunity in which the body produces its OWN antibodies against infections. While PASSIVE IMMUNITY is the form of acquired immunity in which an individual is PROTECTED AGAINST INFECTION BY RECEIVING ANTIBODIES.
NATURAL ACQUIRED IMMUNITY
when attacked by the same pathogens again, they don't became seriously ill. this is because memory cells are able to recognise the antigens and stimulate the immune system to produce antibodies against the pathogens. This is known as NATURAL ACTIVE ACQUIRED IMMUNITY. It develops when one recovers from an infection.
During pregnancy, the mother passes antibodies across the placenta to the foetus. At birth the baby gets antibodies from the mother through breast milk. This is natural passive acquired immunity.
Answer:
C. The ratio would not show any changes in the following year.
Explanation:
Since the introduced (and only) predator can not differentiate between the tone of the lizards (dark and light), you can assume it will feed from them in an equal proportion, so the ratio between dark green and light green lizards will not be affected.
Answer:
Aseptic technique is important in the microbiology laboratory health care industry because it reduces the contamination risk that can have serious implications on the health of a person.
If aseptic procedures are not performed in the Microbiology laboratory and health care industry then there would be chances of getting the disease because in health care industries pathogenic samples from patients are processed which can be transferred in the employee while processing if correct aseptic technique is not used.
Aseptic procedures include wearing lab coats and other protective suits while working which cover all body and give protection from entry of pathogens. Sterilization of surface where work is going on, proper sterilization of all pathogenic cultures.
Therefore aseptic procedures are important to avoid contamination in the microbiology laboratory.
B. The thinner a wire is, the more resistance is will have.
The answer is; Warm water moves to the east instead of to the west
Normally, when the waters in the Pacific warm up, the prevailing winds that blow from east to west drag the warm surface currents westwards and upwelling of cold currents occur at the west coast of South America. However, in El Nino, the Pacific ocean waters heat more than usual. The prevailing winds weaken and begin to blow predominantly towards the east. The warm currents are therefore dragged to the east and cause torrential rains in Western coast South Americas.
