Answer:

The football has kinetic energy and the apple has potential energy.

Explanation:

Potential energy is the energy of an object at rest. Because the apple is hanging from a tree, it is not moving. Therefore, it has potential energy.

Kinetic energy is the energy of an object in motion. Because the football is moving from being in the air to hitting the ground, it has kinetic energy. When it hits the ground, the kinetic energy gets transferred into the ground.

Hope this helps.

In order to provide sufficient food for a group of indigenous people in the Amazon, a section of rainforest will be cut down to
SVEN [57.7K]

A trade-off is the right answer.

A trade-off) is a situational determination that includes reducing or dropping a degree, amount or resources of a set in return for accumulations in other perspectives.

People in the Amazon performs the task of logging that is the cutting of the trees and storing the wood onto cars or wagons for the purpose of cleaning the forests for agricultural production to meet the demand of people for food. However, this activity of people in Amazon has caused a major problem of deforestation. Thus, the reduction in biodiversity is a trade-off between protection and economic expansion.

Which body part from other systems does not interact directly with breathing?
Stels [109]

Answer:

The process of physiological respiration includes two major parts: external respiration and internal respiration. External respiration, also known as breathing, involves both bringing air into the lungs (inhalation) and releasing air to the atmosphere (exhalation). During internal respiration, oxygen and carbon dioxide are exchanged between the cells and blood vessels.

Respiration begins at the nose or mouth, where oxygenated air is brought in before moving down the pharynx, larynx, and the trachea. The trachea branches into two bronchi, each leading into a lung. Each bronchus divides into smaller bronchi, and again into even smaller tubes called bronchioles. At the end of the bronchioles are air sacs called alveoli, and this is where gas exchange occurs.

An important structure of respiration is the diaphragm. When the diaphragm contracts, it flattens and the lungs expand, drawing air into the lungs. When it relaxes, air flows out, allowing the lungs to deflate.

Common mistakes and misconceptions

Physiological respiration and cellular respiration are not the same. People sometimes use the word "respiration" to refer to the process of cellular respiration, which is a cellular process in which carbohydrates are converted into energy. The two are related processes, but they are not the same.

We do not breathe in only oxygen or breathe out only carbon dioxide. Often the terms "oxygen" and "air" are used interchangeably. It is true that the air we breathe in has more oxygen than the air we breathe out, and the air we breathe out has more carbon dioxide than the air that we breathe in. However, oxygen is just one of the gases found in the air we breathe. (In fact, the air has more nitrogen than oxygen!)

The respiratory system does not work alone in transporting oxygen through the body. The respiratory system works directly with the circulatory system to provide oxygen to the body. Oxygen taken in from the respiratory system moves into blood vessels that then circulate oxygen-rich blood to tissues and cells.

How does the process of smooth muscle contraction differ from contraction in skeletal muscle?
Lana71 [14]

Similar to the other types of muscle, smooth muscle contraction is caused by the sliding of myosin and actin filaments over each other. Calcium initiates contractions in a different way in a smooth muscle than in a skeletal muscle.

Smooth muscles use less energy to generate the given amount of force, can substain contractile force without fatigue & uses calcium from the sarcoplasic reticulum & extracellular space.
