The Earth and Moon compare in terms of gravitational force as Earth's gravitational force is stronger than the Moon's.
Option A
<u>Explanation:</u>
According to universal law of gravity, the gravitational force is the attractive force between two objects separated by a distance. The magnitude of gravitational force is directly proportional to the product of masses of the objects and inversely proportional to the square of the distances between them.
In this case, the gravitational force acting on us due to Earth will be considered due to the mass of Earth as the mass of Earth is very large compared to our mass.
So as the mass of the Earth is greater than the mass of the moon, so the gravitational force of Earth will be stronger than that of Moon.
I’m pretty sure it would be: make proteins, release wastes, and builds walls
Answer:
A)100mL B)50mL C)The second option D)Hypoosmotic Environment
Explanation:
The average Na concentration in the seas and oceans of the world is around 3,5% which mean that in 100 ml of sea water, there is around 3,5 grams of Na.
The weight of one mol of NaCl is 58,44 grams. For 3,5 grams of NaCl, we get 3,5/58,44 = 0,060 mol of NaCl which is 0,060x1000 = 60 mmol/100ml. According to this and the information given in the question about the secretion of the salt glands', if the average sodium concentration is 600mmol/L, we have 60*10 = 600mmol/L so it would take 100 mililiters of water to excrete.
If the average Na concentration of the salt gland's secretion were 300 mmol/L, only 50 mililiters of water would be needed to excrete the same sodium load.
The second option of secretion is hyperosmotic to seawater because the concentration is higher.
Osmoregulation is the process of balancing the amount of water and salt between the body of the organism and its surrounding environment. For salt glands to be advantageous for osmoregulation, they need to be in a hypoosmotic environment.
I hope this answer helps.

Explanation:
we all need that all of then helps to increase erosion rates
The following should not be used to reduce the resistance of going to bed for a young child.
<u>Explanation: </u>
- If the child feels sleepy at 10.30 pm and you want the child to sleep at 8.30 pm, never force them to the time you want them to good to bed. instead, make the time they feel sleepy as temporary bedtime.
- Never to feed them with the heavy diet for making them fall asleep may extend the time of the digestion process or lead to stomach illness during late night.
- Avoid stimulating high energy activities like playing outside, running around, watching exciting TV shows.
- Don't discuss or argue about bedtime with your child.
- Once the child is put to bed immediately leave the room if not that will not allow the child to fall asleep soon
