Answer:
The correct answer is c. Bacteremia
Explanation:
Nosocomial infection is a hospital-acquired infection. Intravenous catheterization is majorly used in hospitals for therapeutic purposes like drug administration, blood sampling, etc.
These catheters are one of the major causes of nosocomial bacteremia in patients. Bacteremia is the condition in which bacteria is present in the blood.
So these catheter can be contaminated with bacteria which came from a patient and when they are used in another patient without proper sterilization they can transfer these bacteria to other patients blood which then cause nosocomial bacteremia.
Answer and Explanation:
In crickets, femur length represents a highly important trait associated with jumping performance - an essential behavior for their survival and reproduction.
According to research, these are the possible advantages and disadvantages in regard to long femur length:
Advantages
- Longer legs [may] provide higher power for the muscles in order to jump.
- Long-legged crickets generate lower reaction forces while performing a jump, which enables them to lose less energy in comparison with crickets with shorter femur length.
Disadvantages
- Longer femurs may increase the total take-off time of a cricken prior to a jump.
- In some cases, longer femurs force insects to develop head or body structures to enable them to 'fit' the legs while they prepare to jump.
- Increased energy loss while jumping from an elevated leaf.
Answer: false
Explanation:
Individuals do not evolve as a result of natural selection over successive generations. Populations evolve ONLY as certain traits become more common and others go away.
