Answer:

Plasma is the highest energy state kf matter consisting of a collection of free-moving electrons, positive ions and neutral particles.

How do particals move around in plasma? plasma particles are spred our and move around randomly, but unlike gas, they contain some free ions and electrons, which gives plasma its ability to conduct electricity.

What is radiation?????????????

Answers

Answer:

Radiation is the emission of energy through space in the form of particles and/or waves. Nuclear reactions are very different from chemical reactions. In chemical reactions, atoms become more stable by participating in a transfer of electrons or by sharing electrons with other atoms.

Radiation is said to be the transfer of heat between two objects without any medium between them , that can help them in heat transfer . Hence radiation is said to be the direct transfer of heat between two objects . For example the heat we get from the sun can be said to be from radiation as there is nothing between us and the sun that is helping the sun's heat reach us . The sun's heat reaches Earth directly . This is an example of radiation; which is a type of heat transfer .

1. Explain what the process of respiration is.
2. List at least 6 of the organs or structures which exist in the
respiratory system.
3. When we exercise, why do we breathe harder?

Answers

Answer:

The process of respiration is breathing

Explanation:

1. The process of respiration is inhaling oxygen and exhaling carbon dioxide.

2. Lungs, Bronchus, Trachea, Larynx, Pharynx, Bronchiole, and Pulmonary Alveolus

3. Our bodies use more oxygen which produces more carbon dioxide. To fulfill the body's needs, your breathing has to increase from about 15 times a minute to about 40–60 times a minute.

Conducts electricity

Answers

The correct answer is conducts electricity.

Metal is a really good conductor and is used in different electronics. It is also ductile, meaning it can be pulled into a thin wire.

Hope you have a wonderful day:)

Wire is typically made out of metal because metal is ductile and conducts electricity.

Ductility is the property of metal which makes it easy to be stretched into wire when drawn without breaking. This is a great feature for wires.

Conductor of  electricity : The ability for a material to allow electricity to pass through it with ease shows it is a good conductor of electricity.This is also a great feature for wires.

The transition metal, copper is usually  preferred for the manufacture of electrical wires This is because apart from being thermal resistant and cheap, it is very ductile and a good conductor of  electricity.

How does the atmosphere make Earth warmer?

Answers

Answer:

Earth's surface warms up in the sunlight. At night, Earth's surface cools, releasing heat back into the air. But some of the heat is trapped by the greenhouse gases in the atmosphere. That's what keeps our Earth a warm and cozy 58 degrees Fahrenheit (14 degrees Celsius), on average.

Explain how getting sick can affect the body’s ability to maintain homeostasis.

Answers

Answer:

If your body manages to maintain homeostasis, then it means everything is in order, and you are in a healthy state. However, getting sick would indicate that your body conditions are not stable. This happens when the homeostasis is disrupted due to the interference of pathogens such as viruses and bacteria; for example, catching a flu virus would cause you to have a fever, cold, sore throat, and muscle aches. These symptoms eventually weaken your body and prevent you from performing your daily life functions.

The homeostasis has been affected while getting sick due to a change in temperature with disturbed electrolyte balance.

Homeostasis has been the ability of the body to maintain the equilibrium balance of the electrolytes, and elements for the proper functioning of the system.

The homeostasis has been maintained with the temperature and balance of the components in the preset limit. However with the change in the homeostasis results in the change in the balance and functioning of the organs.

While getting sick, we have changes in the body temperature along with electrolyte dis-balance. This results in disturbed homeostasis.

How do you think the presence of farms will affect the oxygen concentration in the ponds? im in sixth grade so i can't really comprehend to much of words lik algae or my teacher will ask me how i got educated on the topic

Answers

Answer:

The more farms the less the oxygen concentration levels. Farmers use fertilizers to increase crop growth. When algae die, bacteria break down their remains, using up the dissolved oxygen in the water. The rapid loss of oxygen, or eutrophication, can kill fish and other wildlife living in the pond or stream.

How does the temperature of water affect its ability to hold oxygen?

Answers

Answer:The solubility of oxygen and other gases will decrease as temperature increases 9. This means that colder lakes and streams can hold more dissolved oxygen than warmer waters. If water is too warm, it will not hold enough oxygen for aquatic organisms to survive.
