Answer:
There is no short answer.
Explanation:
Gravitational attraction depends on two factors, the mass of the objects and the distance between them.
In the example given in the question, the gravitational attraction to the moon would be much higher than the gravitational attraction to the cat because of the big mass difference between them even though the cat is closer to Tina.
I hope this answer helps.
Answer: please add a clear picture
Most organisms in the top levels of an energy pyramid require more food than those on lower levels. On top of this, each level of the pyramid looses energy gained from food. This means that there needs to be more lower leveled organisms for the ones on top to eat in order to gain enough energy. Because of this, there's only enough food for a few of these types of organisms.
I hope this helped! There are probably a few more details you can add, but this is the overall reason :)
Answer: salt intake increases the sodium level in the blood and will make the body retain excess water thereby giving the heart more work to do.
Explanation: Eating salt increases the quantity of sodium in blood and it creates an imbalance in the sodium and potassium levels. The high level of salt reduces the ability of the kidneys to excrete water. Too much sodium increases blood pressure because it holds excess fluid in the body and that results to an added burden on the heart. Excess sodium intake will increase risk of osteoporosis, stomach cancer, stroke, heart failure and kidney disease.
The result is a higher blood pressure due to the fact that the body will have the tendency of retaining more fluids because of the excess salt.
