<u>Answer:</u> The weight of the person above the surface of a planet is 635.83N.
<u>Explanation:</u>
To calculate the weight of a person, we use the formula:
....(1)
where,
w = weight of an object
m = mass of the person = 65kg
g = acceleration due to the gravity of the planet
For the calculation of weight, we need to first find the acceleration due to gravity and for that we use the formula:
where, g = acceleration due to gravity = 
G = Universal gravitational constant = 
M = mass of the planet = 
r = distance of the person from the planet = 
Putting values in above equation, we get:
Putting this value in equation 1, we get:
Hence, the weight of the person above the surface of a planet is 635.83N.
Hydrogen bonds exhibit the stronger intermolecular force, and water is a polar molecule, so the hydrogen bonding create strong forces which take more energy to break (causing the surface tension of water), and due to the polarity water molecules “stick” to one another which causes the edges to rise up in a tube, forming a meniscus
Answer:
Most probably it would die. Or would be harder for it to live.
Explanation:
On daily basis, as most of the cells die and new cells are formed by cell division. If an organism lost the ability to perform cell division it would die.
Biodiversity boost the eco-system which essentially is the same reason we have plants without biodiversity we wouldn't have plants or trees. Therefore we wouldn't have oxygen so the more we kill the Eco-system the more our planet and life becomes more and more threatened therefore the more food supply and demand becomes less and less. Which basically leads to extinction. So biodiversity is also helpful for biodegradable products like plastic instead of foam. Essentially recycling basically saves our planet.
The correct answer is B. Natural selection occurs through generations and is in which organisms best suited to their environment survive.
