Yes. Absolutely. Without heart, no one can live. It helps in pumping of oxygen rich blood to all body cells and tissues. It also helps in transportation of various materials like potassium, sodium, calcium etc. in our body. The main function is that it helps in excretion of wastes.
Since blood is liquid and heart pumps it, the waste materials like CO2, gets diffused and becomes impure blood. Then it is taken to lungs for purification and again reused.
So, heart actually helps us indirectly in many ways.

Tides occur in ocean,why?
Answer:
¿Qué Causa las Mareas? Podemos decir de una manera sencilla que las fuerzas de atracción que tanto el sol como la luna ejercen sobre la tierra, permiten una deformación y consecuente movimiento de las masas de agua de mares y océanos; esto hace que los niveles de agua suban y se formen las mareas.NOTA: Aquí anexo la respuesta en ingles.What Causes the Tides? We can say in a simple way that the attractive forces that both the sun and the moon exert on the earth, allow a deformation and consequent movement of the water masses of the seas and oceans; This causes the water levels to rise and tides to form.

how the consumers in one level of the pyramid obtain energy from the organisms at the previous level of the pyramid
Answer:
by feeding on the organism on the previous level, the consumers at each level will receive energy. However, most of the energy is lost at each trophic level and very little gets transferred from one trophic level to another. Approximately, 10% of the energy is transferred from one trophic level to another.
Explanation:
hence, when a level takes energy from a previous level, the engery transfers but slowly gets less, so some levels get less energy depending on where the engery was located.
what are the effects of changes in one of earth four spheres on each of the other spheres?

You are heating a substance in a test tube. Always point the open end of the tube
A. toward yourself.
B. toward your lab partner.
C. toward another classmate.
D. away from all people.
Answer:
D
Explanation:
keep test tube away from all people
Always point the open end of the tube away from all people because the chemical is dangerous for human health and skin.
If we heat a substance or chemical in a test tube, we should hold it away from people because may be it can explode and the chemical split on the body that cause serious problems in people. We have to handle laboratory procedures very carefully because the chemicals are not good for health and can cause serious diseases in humans and can damaged the skin very badly so we can conclude that the open end of the test tube should be placed away from the people.

B. Ecosystem will trigger Secondary Succession
C. Decrease in competition
D. Decrease in niches
Answer:
A
Explanation:
succession is replacement of one ecosystem by another so this cause increase in biodiversity
When an ecosystem goes through succession, the biodiversity of the ecosystem tends to increase. Thus, the correct option is A.
What is Succession?Succession may be defined as the gradual and continuous replacement of one community by another community over a long period of time.
Succession is always taking place by a better competitor. The first arrived species is known as the Pioneer species. Intermediate species are known as seral communities, while the highest species is known as the Climax species.
Overall, it increases the biodiversity of the region.
Therefore, the correct option is A.
