The concentration of lactic acid in the student's
muscle tissue was most likely greatest during trial
A) A В) В
C) C D) D

Answers

Answer 1

Option D has the highest concentration of lactic acid in the student's muscle tissue.

We can arrive at this answer because:

Lactic acid increases its concentrations in the muscle due to a high physical effort in anaerobic conditions.This promotes a lack of oxygenation in the muscle, which through contractions, causes the cell to partially catabolize glucose molecules.The result of this is the creation of two pyruvic acid molecules, which will react with NADH2 molecules, creating lactic acid, which will build up in the muscle as the exercise continues.

As we can see in the information presented above, option D shows the performance of flexions with more intensity and for a longer period, which justifies a greater accumulation of lactic acid in the muscle.

It is important to remember that the accumulation of lactic acid in the muscle is a negative situation and that it can cause muscle pain and fatigue.

Many farmers and gardeners compost their plant and animal waste. The living material naturally decays in compost bins, forming a dirt-like substance that’s rich in nutrients. The next season, farmers use this substance as a natural fertilizer for their crops.


A biology student has grown tomato plants for several years. Until now, he used an artificial fertilizer formulated for tomato plants. This fertilizer caused his plants to grow faster and taller than they grew in unfertilized soil. The student wants to know whether using natural compost will cause his tomato plants to grow faster and taller than his artificial fertilizer.


Answer the following questions to plan an investigation using the steps of the scientific method and help the student find the answer to his question.


Part B - Whats the students scientific question?

Part C - Construct at least two possible hypotheses for the students experiment

Part D - Choose one hypotheses to make a prediction

B- Do tomato plants grow faster and taller using natural compost or artificial fertilizer?

C- 1: Tomato plants grow faster in compost than in fertilizer. 2: Tomato plants grow taller in compost than in fertilizer.

D- Tomato plants grow taller in natural compost rather than artificial fertilizer.

E- First, I would plant three tomato plants in different pots. One would be full of natural compost, one full of artificial fertilizer, and one with regular dirt. Then, I would wait a few months, giving them the same amount of water each day, and record the results. The independent variables are the amount of time and water, while the dependent variable is the height of the plant after a few months.

F- My design includes a control group, being the plant with the plain dirt, as well as minimizing error by treating the plants with the same amount of water.

G- After a few months, I would record the height of all three plants and see if the tomato plants grown in natural compost or artificial fertilizer were taller.

Answers

It has to filter out the small amount of oxygen in the water, unlike terrestrial creatures.

Since the amount of oxygen dissolved in water is comparatively lower than that in air, the aquatic animals have to breath rapidly to take in sufficient oxygen. Thus, the rate of breathing in aquatic organisms is much faster than that seen in terrestrial organisms

Answer:

Agriculture gave people the opportunity to create civilizations, fight hunger and work to combat challenges in population growth and climate change.

Explanation:

Another positive development in farming is the rapid expansion of farmers markets. Farmers markets allow small farmers to interact directly with consumers. The food system remains within the local economy by being locally produced and eliminates the need for long-distance transportation. The opportunity to purchase locally grown food proves invaluable as the demand for it rises.
