Answer:

C. Water

Explanation:

The cells in our bodies are full of water. The excellent ability of water to dissolve so many substances allows our cells to use valuable nutrients, minerals, and chemicals in biological processes. Water's "stickiness" (from surface tension) plays a part in our body's ability to transport these materials all through ourselves.

A car lift has an input piston that has an area of 50 cm² and an output piston that has an area of 200 cm². If a 100 N force is

pogonyaev

Answer:

The force produced by the output piston is 400 N.

Explanation:

Given;

area of the input piston, A₁ = 50 cm²

area of the output piston, A₂ = 200 cm²

load on the input piston, F₁ = 100 N

Let the force produced by the output piston, = F₂

From Pascal's principle, the ratio of the input force to the input area is equal to the ratio of the output force to the output area.

$\frac{F_1}{A_1} = \frac{F_2}{A_2} \\\\F_2 = \frac{F_1A_2}{A_1} = \frac{100 \times 200}{50} = 400 \ N\\$

Therefore, the force produced by the output piston is 400 N.

Why do scientists use a light year to measure distances in space?Do you think there is a better way to measure distance? Explain

leva [86]

Scientists use the light year because nothing can travel fast than light. Therefore, in any given time frame, light will travel farther than any other substance or particle in the universe. For more precise measurements, scientists use astronomical units. One AU is equal to the distance between the earth and the sun. For anything less, scientists usually use kilometers. For extremely large, interstellar distances, light years are very useful. You wouldn’t want to measure the distance between Earth and Proxima Centauri in kilometers or even AU. The lightyear gives a simple, relative measurement.

At the end of the term, the professor locks the students in the classroom with plenty of food and water and leaves them there fo

levacccp [35]

Answer:

a. 0.7

b. 0.3

c. Yes

d. 90

Explanation:

As the random mating population was escaped from external evolutionary forces such as mutation, natural selection, and migration, the gene frequency will not change over time. The population will be at Hardy-Weinberg equilibrium throughout the time.

As the number of sleepyheads (recessive trait) was 90 out of class of 1000 students at the start of course.

q²=0.09 ∵ fraction of sleepyheads = 90/1000 = 0.09 denoted by q²

q that is the recessive gene frequency will be equal to 0.3 (by taking square root of P²

Hence, allele frequency of a allele is 0.3

As, frequency of dominant allele A is denoted by letter p and p+q=1

∴ p=0.7 As p=1-0.3

Hence, allele frequency of A allele is 0.7

Counting the probability of aa alleles (sleepyheads);

As a= 0.3

∴ aa= 0.3×0.3 = 0.09 (In terms of percentage, it is 9%)

To 0.09×1000= 90 or 9% of 1000 = 90

Hence, 90 students should be sleepyheads.
