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

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.

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 .

Every Cell in the body requires oxygen for respiration so that sufficient energy can be produced. Carbon dioxide, a waste product, is also produced and needs to be removed.
Therefore, the levels of both gases must be regulated. How does this explain the changes in our pulse rates

Answers

Answer:

Your pulse will go higher or lower, This explains the changes in our pulse rate because, our heart is having to work twice as hard. Our heart is having to work twice as hard because while its producing oxygen its also getting rid of the Carbon Dioxide. while you are jogging or doing any physical activity than your body requires alot of energy and produce a lot of carbon dioxide which causes the heart to beat fast as to remove co2 and take o2 from the blood leading to higher rate of pulse. on the secon hand if you are sedentary , consumption and production of o2 and co2 respectively will decrease leading to the slow beating of heart leading to low pulse

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.

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.
