Blood is essential for delivering oxygen and nutrients to cells, eliminating waste products, aiding in our immune response, and carrying hormones. The heart is responsible for pushing blood through the body using muscular contractions.
Blood is a crucial part of our body's operating system. It has several key roles, including delivering oxygen and nutrients to cells, removing waste products, aiding in our immune response, and facilitating hormone transportation. The organ that pushes blood through your body is the heart. The heart's muscular walls contract, creating pressure and pushing blood through a network of veins and arteries in a process known as circulation.

Answer:
The correct answer will be -The background appears brighter than the specimen which appears darker.
Explanation:
The light microscope uses sunlight energy to view the specimens in the microscope.
The light microscope is of two types depending on the appearance of the background of the specimens: Bright-field and Dark field specimens. Since in bright-filed microscope, the specimens appear darker than the background which appears darker helps visualize the sample clearly.
Thus, The background appears brighter than the specimen which appears darker is the correct answer.
When you heat up an object, the particles in the object move away from the heat source. The heat energy form the source transfers to the particles which causes them to be excited to move and go in any direction away from the source. It increases the kinetic energy of the particles.
