Describe and the explain the changes in blood lactic acid and concentration shown in the graph || guys someone please help i’m f
7nadin3 [17]
During the exercise period (10-15min) the blood lactic acid concentration increases to about 13.2 mmol/dL (same units as on graph) as the individual is having problems keeping up their aerobic respiration. After 15min, they stop exercising and the lactic acid concentration starts to return to normal as their body is able to take in enough oxygen and catches up with the excess lactic acid, metabolizing it into CO2 and H2O. The period between 15-20 min shows the fastest reduction in concentration.

What do you already know about conservation? Think about wildlife and the environment
Elenna [48]

Answer:

Wildlife is living organisms, like plants and animals that live anywhere in the world that they are not isolated in a certain area.

Explanation:

Each wildlife creature lives in an ecosystem that their bodies can tolerate and be able to survive in.

  • Penguin´s bodies are adapted to keep them warm in Antarctica, if they are in warm climates they would overheat.
  • Cold-blooded animals like iguanas cannot live in cold climates because their body temperature would be according to what they feel, so living in cold climates would cause them to die from hypothermia.

Hope it helps:)

How do researchers hope to understand healthy aging by the study of proteins?
nataly862011 [7]

Answer:

Of course, you could scan their driver’s license or look for signs of facial wrinkles and gray hair. But, as researchers just found in a new study, you also could get pretty close to the answer by doing a blood test.

Woman looking at herself in mirror That may seem surprising. But in a recent study in Nature Medicine, an NIH-funded research team was able to gauge a person’s age quite reliably by analyzing a blood sample for levels of a few hundred proteins. The results offer important new insights into what happens as we age.

Explanation:

For example, the team suggests that the biological aging process isn’t steady and appears to accelerate periodically — with the greatest bursts coming, on average, around ages 34, 60, and 78

1. Why are new biomedical products created and what factors influence them to evolve over
Zanzabum

Answer:

Rapid progress in biomedical science has also encouraged the development of multiple successful medical technologies, but their translation into clinical use has posed complex scientific, cultural, and social problems. As demonstrated by the development of new acquired immune deficiency syndrome (AIDS) medications, the rise of these problems is spurring new interest in medical innovation.

Biomedical products are created for better results in medical technology including autoclave / sterilizer, anesthesia machine, aspiration/suction pump, and blood chemistry analyzer etcetra.

Factors influencing them includes harmful effect on other body parts ( beta blockers have harmful effect on heart), outdating technology, and introduction of evolved diseases that is not abl to cure with old products.
