Answer:
Explanation:
The musculoskeletal system provides a framework to the body. It provides the support and maintains the stability in the body. The musculoskeletal system is composed of bones, muscles, cartilage, joints, tendons and ligaments and other kind of connective tissues that support and binds the tissues and organs together.
A strong musculoskeletal system includes three long term health benefits:
1. Reduce the risk of injury: The strong bones and muscles will prevent any internal injuries as they make up a strong framework against external force and internal muscular stress.
2. Decrease the risk of osteoporosis: The osteoporosis is condition in which pores develop on the bones as a result of which the bone becomes brittle and fragile. If the skeletal system is strong then risk of osteoporosis will also decrease.
3. Improve posture: A strong musculoskeletal will keep the vertebral column upright not in bended state.
Types of energy is described below.
Explanation:
1.There are many different types of energy, which all fall into two primary forms – kinetic and potential. Energy can transform from one type to another, but it can never be destroyed or created.
2. Types of energy can be categorised into two broad categories – kinetic energy (the energy of moving objects) and potential energy (energy that is stored). These are the two basic forms of energy.
3.The different types of energy include
- Thermal energy-Thermal energy is created from the vibration of atoms and molecules within substances.
- Radiant energy-Also known as light energy or electromagnetic energy, radiant energy is a type of kinetic energy that travels in waves. Examples include the energy from the sun, x-rays and radio waves.
- Chemical energy-Chemical energy is stored in the bonds of atoms and molecules – it is the energy that holds these particles together.
- Nuclear energy-Nuclear energy is stored in the nucleus of atoms. This energy is released when the nuclei are combined (fusion) or split apart (fission). Nuclear power plants split the nuclei of uranium atoms to produce electricity.
- Electrical energy-Electrical energy is the movement of electrons (the tiny particles that make up atoms, along with protons and neutrons). Electrons that move through a wire are called electricity. Lightning is another example of electrical energy.
- Motion energy-Motion energy – or mechanical energy – is the energy stored in objects; as objects move faster, more energy is stored. Examples of motion energy include wind,
- Sound energy-Sound energy is the movement of energy through substances. It moves in waves and is produced when a force makes an object or substance vibrate.
- Elastic energy =Elastic energy is a form of potential energy which is stored in an elastic object - such as a coiled spring or a stretched elastic band
- Gravitational energy-Gravitational energy is a form of potential energy. It is energy associated with gravity or gravitational force
Answer:
1. Medulla
2. Heart rate and breathing
Explanation:
The brainstem is the part of the brain that was formed earlier in the history of the evolution of the brain, therefore, is present in the posterior region of the brain. The brainstem is composed of three parts called the pons, the midbrain and the medulla.
The medulla is the portion which is connected to the spinal cord and thus the transfers the signals form the spinal cord to the brain structures.
The brainstem controls the main functions of the body like the breathing rate, the heart rate, consciousness, blood pressure and many involuntary functions.
Thus, Medulla and Heart rate and breathing are correct.
