Answer:
250 years
Explanation:
The Atlantic Ocean is not static, but instead it is very active, and it is actually spreading from its central part. In its central part, this ocean has a mid-ocean ridge. This basically means that there is constant formation of new crust from the magma that comes out, and the old crust is pushed sideways as the new one is formed. On an annual level, the mid-ocean ridge is spreading out by an estimated 0.02 meters, thus that is how much the Atlantic Ocean is spreading out each year. In order to get to the result as to how many years are needed for the Atlantic Ocean to spread 500 cm, we just need to multiply the annual spreading with the number of cm in question:
0.02 x 500 =250
Thus we get a result of 250, meaning that in 250 years the Atlantic Ocean will spread out 500 cm in total.
Answer:
the correct answer is D
Explanation:
skin excretes sweat; lungs excrete carbon dioxide; kidneys excretes urine so these organs excrete metabolic waste because if you have learnt about the excretory system, you will come to know the process of excretion and how we humans excrete metabolic and toxic waste from the body.
Answer:
On the basis of the given information, that is, the ape exhibiting small incisors and biphodant molars, shows that they generally consume fruits and seeds as the prime part of their diet. Thus, mainly the apes feed on fruits, leaves, and seeds, thus it makes them vegetarian.
However, it has also been observed that canine teeth are found in both males and females, though they are larger in males. This shows that apes can consume meat from small birds and animals occasionally.
Answer:
A plant cell is surrounded by rigid cell wall whereas animal cell does not have cell wall. Presence of a large vacuole in plant cell, which is small in animal cell. Plant cells are larger than animal cells. Plant cells have plastids whereas animal cells do not have plastids.
Answer:
...a force acts upon it.
Explanation:
"An object in motion tends to stay in motion unless a force acts upon it."
This same rule implies to running water. Water typically runs from a higher place to a lower place with the usage of gravity (except for certain rare cases). Until there is something blocking (for example, a dam, or a let down in the steepness of the drop), the water will continue to move forward.
