The circulatory system is important in meeting the needs of all cells in the body because it offers means of transport by which cells obtain the materials needed to live and function.
The functions of the circulatory system by which the cells are supported include:
1. Respiration- oxygen is delivered to the cells and carbon dioxide is removed from them.
2. Nutrition- nutrients for energy are supplied to every cell in the body.
3. Waste removal- metabolic waste products are taken away before they accumulate and become harmful to the cells.
4. Cellular communication- hormones are transported to the cells and organs that need them for proper functioning.
5.Thermoregulation- As blood circulates, it keeps body temperature balanced and thus cells are able to carry out processes well.

Astronomers suspected an eighth planet beyond Uranus because of the irregularities in the motion of Uranus suggested that gravity from another planet was affecting it.
<h3>Who is an astronaut?</h3>
It should be noted that an astronaut simply means an individual who is trained to travel in spacecrafts.
In this case, astronomers suspected an eighth planet beyond Uranus because of the irregularities in the motion of Uranus suggested that gravity from another planet was affecting it.
In mid-1800s, astronomers used the orbits of most asteroids to predict where a planet would have to be.

Archimedes and the principle of flotation ... "Cast iron sinks" ... unless it's a ship, of course is an old joke.
What has to happen is that supposing the object has a mass of 1kg, then it has to displace 1kg of water to float. However the volume of the object is decided by the object's density. Unless, that is, it is "hollowed out" or otherwise manipulated, such as is done in the hull of a metal ship ...
There's a thing called a "Eureka can" used in physics labs.
Answer:
X component= 46 N
Y component= 80 N
Magnitude =( 46 ^2 + 80^2 )^0.5 = 92.3 N
