9. When your muscles do not get enough oxygen during a strenuous workout, glucose cannot be broken down properly.
a. What chemical builds up in the muscles and causes pain?
Do some research about this build-up.
b. What can you do to prevent it?
c. How can deep breathing help reduce it?
d. How can water help reduce it?
Answer:
a. lactic acid, b. stretch and drink lots of water, c. oxygen is needed, d. to stay hydrated?
Explanation:
a. i believe it's called lactic acid? when you don't get enough oxygen to the muscle, it starts to cramp up
b. you can do stretches to ease up tense muscles
c. because it gets oxygen to your muscles
d. to hydrate, helps to keep the muscle cells to relax and more hydrated, becoming less irritable.
i hope this helped :)
Answer: during exercise, lactate builds up in muscles and causes a burning pain in the affected muscle
Explanation: Exercise increases the energy needs of the muscles used. Increased energy generation requires increased oxygen. If energy demands exceed the body’s ability to supply oxygen, muscle tissues switch from aerobic to anaerobic respiration.
In anaerobic respiration pyruvate is reduced to lactate. Energy production is <10% as efficient as aerobic respiration, so it must be at a high rate.
C3H4O3 + 2NADH + 2ADP + Pi —> C3H6O3 + 2NAD+ + 2ATP
Reducing intensity of exercise or taking breaks can give the body a chance for recovery. Aerobic fitness will increase ability to supply oxygen.
After exercise, lactate is converted back to pyruvate and to replenishing glucose via gluconeogenesis. The enzyme lactate dehydrogense catalyses the pyruvate/lactate reaction in both directions.
The cumulative effect of exercise and converting lactate back to pyruvate creates an ‘oxygen debt’ which is why we breathe heavily after exercise.
Exercise can lead to dehydration (e.g. sweating) which decreases metabolic efficiency. Additional water intake before during and after exercise prevents dehydration.
It has also been shown that light exercise in the recovery phase after strenuous exercise improves the rate of lactate removal
Menzies et al. Blood lactose clearance during active recovery after an intense running bout depends on the intensity of the active recovery. J. Sports Sci 2010; doi 10.1080/02640414.2010.481721

Answer:
Mesophyll cells.
Explanation:
Transpiration is the evaporation of water at the surfaces of the spongy mesophyll cells in leaves, followed by loss of water vapour through the stomata . Transpiration produces a tension or 'pull' on the water in the xylem vessels by the leaves. Water molecules are cohesive so water is pulled up through the plant.

in the cytoplasm, Here, three bases, called a CODON, will determine what acid is added to the chain. This chain will fold into a TERTIARY STRUCTURE.
Explanation:
I'm not too sure about "protein site," but I hope the rest helps!
Answer:
DNA is composed of sugar, phosphate and four nitrogen bases (A, T, G, C). During transcription, DNA is made into a molecule of RNA, which will travel to the ribosomes in the cytoplasm. Here, three bases, called a codon, will determine what amino acid is added to the chain. This chain will fold into a protein. This shape of this molecule determines how it functions.
Changes in the DNA code are called mutation and they can cause a protein to not function properly. A single change in the DNA of the hemoglobin gene will cause sickle cell anemia.
Explanation:
Adenine (A), Cytosine (C), Guanine (G), and Thymine are nitrogen bases. A and T pair together while C and G pair together. In DNA/RNA pairings, A pairs with Uracil (U). Transcription happens in the RNA, which is sent from the nucleus to the ribosomes (where protein is made). The three bases are called codon, their three base pairing is called an anticodon.
DNA gets mutated and this causes changes in the code. Sickle cell anemia occurs in the hemoglobin.

describe 4 ways a temperature increase of only 1c (global warming) would impact humans and / or ecosystems
Answer:
1. Food cycle- With Global Warming on the rise the food cycle is being thrown off due to some animals dying off because they aren't getting used to the extreme sudden heat this can also affect humans especially if we seafood. Global warming affects the ocean too killing off a lot of sea creatures that we eat sometimes like Shrimp for example. Study shows that Global Warming is heating up the ocean cooking the live shrimp in the ocean.
2. Timing of seasonal changes- Study shows that places that don't get hit by snowy weather in the Wintertime are getting pounded by winter storms. A perfect example of this is East Coast getting hit by wintery weather while West Coast sees some high temperatures with no moisture this is caused by global warming.
3. Extinction Risks- Another study shows that some animals such as elephants, Siberian Tigers, red Pandas are all on the Endangered species list due to the sudden change in the weather because of Global Warming which brings the extinction-level to an almost high rate. People all around the world are trying all they can to prevent animal species to go extinct and as I mentioned before if a species goes extinct it'll throw off the food cycle.
4. Range shifts- Since the temperatures are changing dramatically because of global warming it is causing a lot of species to migrate to a new area this is their way of surviving instead of dying off this can also disrupt the food cycle because if a certain species a predator perhaps moves to a different area the prey species will increase and those predators that migrated to a new area is causing a lot of habitat changes to another species its like natural selection and can cause a pretty bad change
So that is why people are up and arms about global warming and why they want to hurry up and come up with a plan to stop global warming or figure out a way to cool down the Earth because it'll not only end in species' extinction but it can lead to Human extinction.
Hope this helped :)

Are there any parts of the human body that get oxygen directly from the air and not from the blood? i don't pay attention in biology
Answer:
The cornea.
Explanation:
The cornea is the only part of the human body that has no blood supply, it gets oxygen directly through the air. Also, did you know that the cornea is the fastest healing tissue in the human body, therefore, most corneal abrasions will heal within about 24-36 hours.

Structure of a virus
Explanation:
At the center of all viruses the DNA or RNA is found enclosed by the capsid. The Capsid is a capsomere (type of protein) coat that is designed to protect the DNA or RNA.
The capsomere contains genes that allow the virus to transfer its nucleic acid into the host cell.
