Separating a mixture of salt and sand will involve two main techniques such as filtration and evaporation.
<h3>What is Filtration?</h3>
This is a technique which is used to separate a fluid from a solid matter such as sand etc.
Since salt dissolves in the water, the fluid is collected using the filter paper placed inside the funnel. After which it enters the Erlenmeyer flask and is heated to allow for evaporation of water and collection of the salt.

Answer:
No streak of light will appear.
Reason I given below.
Explanation:
No streak of light will be seen.
This is because as it falls to the moon, the gravitational pull plus the dense atmosphere which was necessary to produce friction when it fell to the earth are not present in this case and as such the whole meteor is not burnt like it did when it fell to the earth.
The practice that has been able to save some organisms from extinction is cross breeding.
<h3>What is cross breeding?</h3>
Cross breeding is the process of producing separate strains of the same species in order to create new traits.
Living organisms are bound to go extinct when faced by certain unfavorable conditions that cannot be adapted to.
However, the production of resistant strains of the same species of an organism via cross breeding can help prevent them from going extinct.
