In biochemical terms, explain what causes lactic acid buildup. (Your answer must include the words: anaerobic, oxygen, lactic acid, ATP)

Answers

Answer:

Lactic acid buildup occurs when there's not enough oxygen in the muscles to break down glucose and glycogen. This is called anaerobic metabolism. There are two types of lactic acid: L-lactate and D-lactate. Most forms of lactic acidosis are caused by too much L-lactate.

Explanation:

hope it helps

Lactic acid builds up in the muscles of mammals due to inadequate oxygen.

During rigorous activities, oxygen supplies become inadequate to generate the necessary energy in the form of ATP from normal aerobic respiration.

Thus, anaerobic respiration is used to supplement the energy needed during rigorous activities.

During aerobic respiration, the presence of oxygen ensures that the 3 steps are complete:

GlycolysisKreb's cycleElectron transport

For anaerobic, only glycolysis takes place and the pyruvate molecules generated are converted to lactic acid. In the presence of adequate oxygen, the lactic acid is converted back to pyruvates which then move into Kreb's cycle.

The 2 molecules of ATP generated from glycolysis are used to supplement the energy needed during rigorous activities.

If a DNA sample is 14% cytosine (C), what percent is thymine (T)?

Answers

Answer:

Thymine = 36%

Explanation:

Since cytosine and guanine are found in similar quantities, their sum can clearly be divided by 2.

As there are only four bases in DNA, you know, all four bases combined must be equal to 100% of the sample. Provided the knowledge that the sample is 20 percent guanine, because guanine and cytosine pair with each other, you might presume it is also 20 percent cytosine. That is, together, 40 percent of the overall sample

B. The Theory of Evolution
C. The Cell Theory
D. The Theory of Spontaneous Generation

Answers

Answer:

I think its D or B. Not sure but its either one

A. The Microscopic Theory is the contribution of different discoveries about cells that laid the groundwork for other fields of science.

Although the theory of evolution, the cell theory, and the theory of spontaneous generation are related to cell but they cannot be directly related to other fields of science. The microscopic theory can be related to other fields of science as it can applied in biology, and physics as well. In biology the microscopy can be used to view the cells their structure and function. In physics it can be used to study the dynamics of microscopic structure and structure and function of lenses.

Hence, A. the microscopic theory is the correct option.

How could the jackrabbit population suddenly increase?How might this affect the ecosystem?

Answers

If there was a lot of breeding, then the population would increase and this would affect the ecosystem in two ways, there would be less vegetation since the jackrabbits would be consuming more, and the other way it would have an affect is that the predators of jackrabbits would suddenly have more food, meaning there could be an increase in predators, and an increase in predators would affect the jackrabbit population negatively if they’re all being eaten

A student put a half teaspoon of yeast in each of three

different balloons. Then he added a quarter cup of water to each balloon. Each balloon received water of a different temperature: hot, warm, and cold. After adding the water, the student tied off the end of each balloon to seal it shut. The yeast began to produce bubbles of gas inside the balloons. After 20 minutes, the student measured the circumference of each balloon to determine how much it had grown in size.

What is the responding variable in this experiment?

A. The temperature of the water balloon

B. The amount of water placed in the balloon

C. The circumference of the balloon

D. The amount of yeast placed in the balloon

I think its D

Your experiment looked at the effect of water temperature on yeast growth.

What is water temperature?The temperature of water is a physical property that expresses how hot or cold it is. Because hot and cold are arbitrary terms, temperature can also be defined as a measurement of a substance's average thermal energy 5. Room temperature (20°C / 68°F) for maximum flavor or chilled cold (6°C / 43°F) for maximum refreshment are the best temperatures for drinking water. A thermistor, a metallic device that undergoes a predictable change in resistance in response to temperature changes, can be used to measure water temperature. This resistance is measured and converted into a temperature in Celsius, Fahrenheit, or Kelvin.
