Which description is an example of converting gravitational energy into kinetic energy?
Troyanec [42]
When an object from a pause state begins to move the potential energy is changed into kinetic energy. One of the example is the yo-yo, it has stored energy due to its position. Once the yo-yo begins its fall the potential energy will change to kinetic energy and vice versa.

Distinguish between systolic and diastolic blood pressure
BartSMP [9]

Answer:

Blood pressure is usually defined as the pressure exerted by the blood that circulates on the walls of blood vessels. This pressure is created when the heart pumps blood continuously throughout the circulatory system.

The blood pressure have two numbers, one at the top and one at the bottom. The number showing at the top shows the amount of pressure exerted on the arteries when the muscles associated with the heart gets contracted. This is commonly considered as the systolic pressure. On the other hand, the number at the bottom shows the amount of pressure that is exerted by the heart muscles between the heart beats and this is known as the diastolic pressure.

The systolic blood pressure is more important compared to the diastolic blood pressure because it enables the person who measures the blood pressure or a doctor, to determine the risk of having a heart attack.

Alex listed the typical steps of fossil formation. 1) An organism dies. 2) The remains fall to the bottom of the ocean. 3) The s
Anna35 [415]

Answer:

The answer is: After step 3, layers of sediment cover the dead organism.

Explanation:

Fossilization is the process by which living things are preserved as impressions on sedimentary rock (fossils). This is a rare process that occurs under the most appropriate conditions.

Process of Fossilization:

Permineralization is one of the most common types of fossilization. It involves the absorption of minerals into the remains, giving a detailed impression of the dead organism.

  1. The dead organism sink to the bottom of the ocean.
  2. The soft parts i.e. the tissue is decomposed whereas the hard parts of the body: the nails, bones and hair remain.
  3. The bones are gradually covered by sediments. The quality of the fossils often depends upon the type and quantity of sediment. River deltas have a large amount of sediment. This speeds up the process. Clay and mud sediments provide more detail to the fossil whereas sandy sediments render the details vague.
  4. Sedimentation is followed by permineralization. As layers of sediment accumulate over each other, the layers underneath turn to rock. This occurs due to the movement of minerals down to the seabed that harden the sediments. Minerals such as calcite may even replace the bones and other hard parts of the fossil, allowing it to remain preserved for long.
  5. The fossils discovered by archaeologists are present relatively closer to the surface of the Earth. This occurs due to the uplifting of rock layers due to the movement of the continental plates.
