The temperature of four ponds was measured at 6:00 am. which of the ponds would probably have the highest dissolved oxygen conce
natulia [17]

<span>Answer: Pond A</span>

<span>The concentration of Oxygen in water is very important in considering the quality of water along with the other physio-chemical characteristics. Thus, oxygen concentration is inversely proportional to temperature and cooler water holds more oxygen compared to warm water. However, fish usually need more oxygen in water water.</span>

Karen is a forensic scientist whose purpose is to identify and evaluate physical evidence. Which of the following tasks does she
Gwar [14]

Answer: A. reporting results of scientific analysis.

A physical evidence, also called real evidence. It is a tangiable evidence, which can be touched, picked and collected from the scene of crime or any other place. It can be used to prove a crime has occurred. Physical evidences includes fingerprints, footprints, fibers, paint and building materials.

A specimen sample is taken from the suspects or victims and compared with suspected samples obtained from the scene of crime. The comparitive analysis of physical evidences can be used as a scientific evidence against criminal.

Therefore, reporting results of the scientific analysis is the task she should perform.

Answer:

Firstly, when we exercise, or do some activity (in this case football), we use more energy than usual...

The reason some of her body systems work faster than normal, is to keep the body working and in the equilibrium, so that she won’t get tired too fast.

Related to circulation, her blood flow increases, since she needs more oxygen to reach the muscles faster, due to the exercise/activity (Lactic acid builds up, so more oxygen is required.)

Her breathing increases to take in more oxygen(O2), and give out more carbon dioxide(CO2).

Her body respires more(respiration), both aerobically(with oxygen), and anaerobically(without oxygen), lactic acid builds up due to anaerobic respiration.

(Here, energy is released from glucose to generate a substance called lactic acid. ... Therefore anaerobic respiration cannot be used for a prolonged period of time without having damaging effects on a cell.)

When she inhales (Oxygen), it goes to the lungs, to the alveoli ( Alveoli are tiny air sacs in your lungs that take up the oxygen you breathe in and keep your body going)

In the Alveoli, diffusion takes place, this is where oxygen is diffused into the blood, and carbon dioxide is diffused (taken into) into the lungs.

Then we exhale, which gives out the carbon dioxide(CO2), this happens really fast, we also breathe so fast, this process happens within seconds.

Red blood cells contain something called haemoglobin, this combines with oxygen To form oxyhaemoglobin, then when the red blood cell reaches the muscle, it gives the oxygen, converting oxyhaemoglobin back to  haemoglobin.

Heart: pumps blood faster (as I said before), to ensure oxygen gets distributed faster to where it’s needed
