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
Explanation:
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.

Charlie is doing a scientific investigation about the properties of light energy. For his experiment, he points a flashlight at a mirror and then at a basketball. Which of the following best describes what Charlie would observe?
A The light traveled through both objects and refracted which made them appear bigger.
B The light was completely absorbed by both objects, and he could see white and blue.
C When the flashlight was pointed at the mirror, the light reflected in the same direction. When the flashlight was pointed at the basketball, the light was reflected in different directions.
D When the flashlight was pointed at the mirror, the light was absorbed. When the flashlight was pointed at the basketball, the light was refracted in a different direction.
Answers
Answer:
its not a its c
i think
Explanation:
When the flash light is pointed to a mirror it absorb some of the light and when it is pointed to the basket ball the light will refract in a different direction.
What is refraction?Refraction is an optical phenomenon in which the light changes is direction or bends when going from one medium to the other.
Mirror is transparent and will absorb and reflect light. Whereas, basket ball is opaque and never shows any reflection or absorption of light. Thus light when travel from air to the solid and then to air it bends in its direction.
Therefore, option D, that is the flashlight is absorbed by the mirror and refracted by basket ball in different direction is correct.

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 .
