Answer:

3.) scientific field that uses technology to purposefully change living things

Explanation:

Science can be defined as a branch of intellectual and practical study which systematically observe a body of fact in relation to the structure and behavior of non-living and living organisms (animals, plants and humans) in the natural world through experiments. One of the most important branch of science is bioengineering. Biotechnology can be defined as a high-tech process which avail scientists the opportunity or ability to modify, remove, replace and insert Deoxyribonucleic Acid (DNA) sequence in a living organism such as bacterias, animals, plants etc in order to correct a genetic disorder and to improve on their physical and chemical conditions.

For example, selective breeding also referred to as artificial selection is being used to create plants that are more resistant to certain biological diseases. Thus, this is an example of an organism being changed through technological methods commonly known as biotechnology.

Hence, the phrase which best defines biotechnology is that, it is the scientific field that uses technology to purposefully change living things.

Use your data (attachment) from Part 3 and Newton’s laws to explain why the force meter measures a force if the cart is moving a
vazorg [7]
The cart experiences a frictional force which is directly proportional to its weight. This means that there must be a force applied on the car to balance the forces on the car to produce a net force of 0.
This is in accordance to Newton's first law which states that an object at rest will remain at rest and an object in motion will remain in motion unless an external force acts on it. The force must be a resultant force.
Therefore, the force needed increases with the total weight of the cart as well as with the added mass in a linear manner.

A sealed test tube traps 25.0 cm3 of air at a pressure of 1.00 atm and temperature of 18°C. The test tube’s stopper has a diamet
puteri [66]

Answer:

180° C

Explanation:

First we start by finding the area of the stopper.

A = πd²/4, where d = 1.5 cm = 0.015 m

A = 3.142 * 0.015² * ¼

A = 1.767*10^-4 m²

Next we find the force on the stopper

F = (P - P•)A, where

F = 10 N

P = pressure inside the tube,

P• = 1 atm

10 = (P - 101325) * 1.767*10^-4

P - 101325 = 10/1.767*10^-4

P - 101325 = 56593

P = 56593 + 101325

P = 157918 Pascal

Now, remember, in an ideal gas,

P1V1/T1 = P2V2/T2, where V is constant, then we have

P1/T1 = P2/T2, and when we substitute the values, we have

101325/(273 + 18) = 157918/ T2

101325/291 = 157918/ T2

T2 = (157918 * 291)/101325

T2 = 453 K

T2 = 453 - 273 = 180° C
