Answer:
El punto de referencia más usado es el NORTE. Los puntos de referencia sirven para orientarnos, de esta manera podemos saber nuestra ubicación y luego desplazarnos. En este caso tenemos que el punto cardinal NORTE es el más usado, se tiene como referencia universal para lograr ubicarnos.

Electromagnetic radiation
<h2>
Answer: Doppler effect
</h2>
Explanation:
A radar gun (also known as a Doppler radar) uses the Doppler effect when measuring "return echoes" after having sent a microwave signal (a type of electromagnetic radiation).
In this context the Doppler effect consists of the change in a wave perceived frequency when the emitter of the waves, and the observer move relative to each other.
In the case of radars, a microwave signal is sent to a target (the tennis or baseball in this case) and then is reflected after "hitting" the target, so that the radar system measures this difference between the sent signal and the reflected signal.
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
