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.
Answer: Mutton
Explanation:
Mutton refers to the flesh of the mature ram or ewe at least one year old.
The acceleration of the car is solved by subtracting the initial speed from the final speed then dividing the result by the elapsed time.
initial speed = 72 km/hr = 20 m/s
final speed = 0 m/s
elapsed time = 5 seconds
acceleration = (0 m/s – 20 m/s) / 5 s
acceleration = - 20m/s / 5 s
acceleration = -4 m/s^2
As we know that P=IV so P = (0.5A)(4.5V)
P= 2.25 watt
