When we run, we sweat, which means we're getting hotter and hotter and our bodies need to cool down, which they do through transpiration (sweating). If we need to cool down, we need to release the heat that is in our bodies.
To run, we also need to move our muscles, which requires a specific type of energy, called mechanical or kinetic energy, which is the "energy of movement". In our bodies, we don't store that type of energy though, so we have to convert chemical energy to mechanical energy.
Answers:
⭕Heat energy is released from the body to the surroundings.
⭕Chemical energy is converted to mechanical energy that’s used for muscle movements.
<span>Sir Isaac Newton quantified the gravity between two objects when he formulated his three laws of motion. ... Yet Newton's laws assume that gravity is an innate force of an object that can act over a distance

In 1905, Albert Einstein determined that the laws of physics are the same for all non-accelerating observers, and that the speed of light in a vacuum was independent of the motion of all observers. This was the theory of special relativity. It introduced a new framework for all of physics and proposed new concepts of space and time.
Einstein then spent 10 years trying to include acceleration in the theory and published his theory of general relativity in 1915. In it, he determined that massive objects cause a distortion in space-time, which is felt as gravity.
Its easer to water because everything rotates around it
Changes in the shape of a cell usually involve a reorganization of the
cytoskeleton.
Cytoskeleton is an interwind filamentous network that mainly keeps and mantains the shape as well as internal organization.
- Hence reorganization is also done with the help of the cytoskeleton.
- Extracellular matrix mainly helps the cell to keep it together.
- Transporter proteins mainly act as a catalyzing agent for various purposes.
- Nucleus is just a genetic material carrying an organelle that regulates the activities of cells.

Answer:The Great Oxygenation Event, which occurred around 2.45 billion years ago, was probably the first major extinction event. Since the Cambrian explosion, five further major mass extinctions have significantly exceeded the background extinction rate.
Explanation:
got this from the internet very helpful :)
