Explanation: Low-density lipoprotein is one of the five major groups of lipoprotein which transport all fat molecules around the body, it can be called bad cholesterol. High level of Low density lipoprotein can lead to diverse health issues such as it increases the risk of cardiovascular diseases, it accumulates in the walls of blood vessels causing the blood vessel to be hard and thick leading to a disease called Atherosclerosis.

The correct answer is C. To reduce the use of artificial pesticides, reduce costs, and control pests.
Explanation
Integrated pest management (IPM) is a method that integrates different practices and scientific principles to make adequate management with pests. This method considers knowledge about the habits, life cycle, needs, and aversions of the pest, reducing the use of toxic methods and implementing less toxic methods, monitoring pest activity and adjusting methods over time, tolerating harmless pests, setting a threshold to decide when it is time to act, among others as its main principles. Therefore, the correct answer is C. To reduce the use of artificial pesticides, reduce costs, and control pests.
Answer:
The deceleration of the plane is 0.25 m/
.
Explanation:
Deceleration is the converse of acceleration.
From first law of motion, we have;
v = u + at
where: v is the final velocity, u is the initial velocity, a is the acceleration and t is the time taken.
Thus,
v = 50 m/s
u = 80 m/s
t = 120 s
50 = 80 + 120a
50 - 80 = 120a
-30 = 120a
a = 
= -0.25
a = -0.25 m/
The deceleration of the plane is 0.25 m/.
