Imagine a car as a model that represents the human body, with its parts performing various functions similar to human body systems. Which two statements are correct analogies? The gas in the car is the digestive system that provides the necessary energy. The frame of the car is the digestive system that provides structure and support to the body. The exhaust system of the car is the excretory system that removes waste. The engine of the car is the digestive system that circulates nutrients to the rest of the body. The oil in the car is the excretory system that protects and coats the body.

b. 1.25 hr

step-by-step explanation:

if you have a constant speed of 60 mph, then you have a ratio between 60 mi. to 1 hr. dividing both sides by 60 we get the ratio

1 mi. to

then mult. both sides by 75 we get the ratio

75 mi. to

simplifying we get

75 mi. to

or 1.25 hr.

16

step-by-step explanation:

explanation:

infrared radiation has wavelength in the range between 700 nm and 1 mm. lets' convert these values into scientific notation, keeping in mind that:

let's start from the lower value, we have:

(we moved the dot two places to the left, so we increased the exponent by 2 units, from -9 to -7)

the higher value is:

so, the range of wavelength of infrared radiation is:
