Answer: choices a and b
Explanation:
Telescope can be defined as am optical instrument which is designed to observe the distant objects clear and nearer. It comprises of arrangement of lenses which allow the rays of light to be collected. The collected light is focused and the image so produced is magnified in the form of an image. The telescopes are prepared and manufactured on mountains top as this will help in preventing the distortion of light obtain from the star due to the fluctuation of air mass in the atmosphere. The atmospheric distortion affects the resolution, and affects the vision. The atmospheric pressure is low at the mountain tops so it will help in better observation of the sky.
Answer
Voltage is how fast the electrons flow. Power is a use of voltage times the volumes of electrons. The higher the voltage the more power you have with the same current.
I would say our solar sustem will die when the sun dies or a black hole sucks it up.
Scientific evidence supports a new idea
Answer:
Explanation:
1 advantage of genetic engineering:
It allows for a faster growth rate. Because with genetic engineering, plants and animals are allowed to be modified so their maturity would occur at a quicker pace.
1 disadvantag of genetic engineering:
The nutrition value of foods can be less. For example, in a research show that genetic enginnering make chicken increase the fat content by 220% but reduced the amount of protein.
1 advantage of cloning:
When cloning, the object would be able to create tissue and organs that doctor can use when needed during the surgery.
1 disadvantage of cloning:
If original organism has genetic deffects, it will be passed down through all the continuous generations
1 advantage of artificial selection (can be called as selective breeding):
It will provide improvements to plants and animals. For example, seedless fruits, increast the tast of food, etc.
1 disadvantage of artificial selection (can be called as selective breeding):
It may lead to a lack of variety in plant or animal species. As the breeding is selective so the variety in plant would be decrease. For example, people like seedless fruits than normal included-seed fruit so that would make the new fruit become more popular and may lead to decrease the diversity in fruits.
Hope this help you :3
AWWWWW TAKE SO LONG TO RESEARCH AND WRITE :D:D
