Answer:

1. lose mass and shrink in size

Explanation

the egg is a more dilute solution that the one it is placed in. Through osmosis it will lose water until both solution(the inside and outside of the egg) have roughly the same concentrations. Losing water will cause it to shrink.

1. The human population is increasing by about 1.19 percent each year. Assume that the
population is 6.8 billion (6,800,000,000).
How large will the population be in one year?

Answers

Should be 8,092,000,000

The population that should be large in one year is 8,092,000,000 when the population should be increased by 1.19 percent.

Calculation of the population:

Since the population is 6.8 billion or 6,800,000,000

And, the increase rate is 1.19% each year

So the population in one year should be

= 1.19% of 6.8 billion

= 8,092,000,000

hence, The population that should be large in one year is 8,092,000,000 when the population should be increased by 1.19 percent.

What is the force of an object if it accelerates 4 m/s2 and has a mass of 10 kg? (F = ma)
A.
0.4 Newtons

B.
2.5 Newtons

C.
40 Newtons

D.
100 Newtons

Answers

Answer:

C. 40 Newtons

Explanation:

We are given the equation to calculate force:

Force=mass×accelleration

To find the answer, we just need to plug the given mass and acceleration into the equation. The units of these values are typically kg and m/s^2 when calculating the force in Newtons, which they already are (so we don't need to do any conversion).

Mass=10kg

Acceleration=4 m/s^2

F=ma

F=10×4

F=40 N

Therefore, the force of the object is 40 Newtons.

The artificial cell in the picture below is permeable to monosaccharides but not polysaccharides. Initially, the artificial cell contained a solution of glucose and starch while the beaker was filled with only water. After a period of thirty minutes, the water solution in the beaker tested positive for glucose. What process allowed for this to occur?

Answers

Answer:

Osmosis.

Explanation:

Osmosis is the process which is responsible for the transportation of glucose inside the cell. Osmosis is a process in which micro-molecules such as glucose, ions and gases etc go inside the cell through a semi-permeable membrane. This semi-permeable membrane of the cell only allow monosaccharides but not polysaccharides because monosaccharides is small in size while polysaccharides are larger in size.

A technological system is a system that consists of components constructed to work together in order to process an input to an output/result. These components or parts that make up a technological system are as follows: input, processing, output and feedback.

- The input is what is taken in by the system.

- The process is the series of occurrences conducted by the internal parts of the system to bring about an output.

- The output is the final result of the system.

- The feedback is how the system should work in comparison to how it is working.

Among all these parts of a technological system, the part that is OPTIONAL i.e the system can function without, is the FEEDBACK.

A balloon is filled with helium in an airplane, where the air pressure is 81 kPa. The filled balloon has volume of 4.2 L. When the plane lands, the cabin is depressurized to the outside air pressure, which is 94 kPa. If the temperature of the balloon remains the same, what is the new volume of the balloon?

Answers

Answer:

3.62L

Explanation:

Using Boyle's law equation i.e

P1V1 = P2V2

Where;

P1 = initial pressure

V1 = initial volume

P2 = final pressure

V2 = final volume

According to information provided in this question, P1 = 81kPa, P2 = 94kPa, V1 = 4.2L, V2 = ?

P1V1 = P2V2

81 × 4.2 = 94 × V2

340.2 = 94V2

V2 = 340.2/94

V2 = 3.619

V2 = 3.62L
