White blood cells work in two ways; they can ingest or engulf pathogens and destroy them by digesting them. White blood cells can also produce antibodies to destroy particular pathogens by clumping them together and destroying them. They also produce antitoxins that counteract the toxins released by pathogens.
It fits into the food web by being a producer by producing light for other organisms such as grass and other plants
Answer: 40731.8 grams of this gasoline would fill a 14.6gal tank
Explanation:
Density is defined as the mass contained per unit volume.
Given : Mass of gasoline = ?
Density of the gasoline = 
Volume of the gasoline = 14.6gal = 55267.01 ml (1gal=3785.41ml)
Putting in the values we get:
Thus 40731.8 grams of this gasoline would fill a 14.6gal tank
Answer:
b. using less water
Explanation:
Pollution can be defined as the physical degradation or contamination of the environment through an emission of harmful, poisonous and toxic chemical substances.
In the United States of America, the agency which was established by US Congress and saddled with the responsibility of overseeing all aspects of pollution, environmental clean up, pesticide use, contamination, and hazardous waste spills is the Environmental Protection Agency (EPA). Also, EPA research solutions, policy development, and enforcement of regulations through the resource Conservation and Recovery Act.
In homes and offices, an effective and efficient design of pipes and other water-related facilities would go a long way to reduce water pollution because the water used are well managed and properly disposed into sinkholes.
Hence, more efficient plumbing reduces water pollution by using less water
Answer: Skier 1 will have more potential energy because he is higher than skier 2
Explanation: Gravitational potential energy is the energy possessed by a body by virtue of its position or height.
P.E=
m= mass of the body
g= acceleration due to gravity
h= height of body
Thus if the masses of two bodies are same, the one with greater height possess greater potential energy.
