2. communicate the results

3. test the hypothesis

4. make observations

5. analyze the results and

make a conclusion

6. ask questions

Pairs

A. Bread, when kept in the open for a

long time, shows the presence of mold.

B. What causes mold growth on bread?

C. Changes in temperature may affect

the growth of mold on bread.

D. Keep the bread in different locations,

changing the temperature at each location.

E. Increased temperature leads to the

growth of mold.

F. Make a presentation of the data, and

explain it to the class.

Explanation:

<h3>ANSWERS :</h3>

1- C ( this is an assumption; a hypothesis is always based on an assumption.

2- F ( this states to share the results with other classmates).

3- D (this is a description of an experiment you could conduct; you test a hypothesis (usually) by conducting an experiment.

4- A (this is something you could observe during the experiment, therefore it is an observation).

5- E (this sentence is a conclusion).

6- B (This is an actual question)

In liver cells, the inner mitochondrial membranes are about five times the area of the outer mitochondrial membranes. What purpo

m_a_m_a [10]

Answer:

Option (C).

Explanation:

Oxidative phosphorylation may be defined as the process of the production of ATP molecule by the use of enzyme and transfer of electrons from one complex to the other complex.

The liver cells has five times large surface area of inner mitochondrial membrane than the outer membrane. This increases the surface area of the inner mitochondrial membrane that increase the rate of the oxidative phosphorylation. The complexes of the electron transport chain is located in the inner mitochondrial membrane.

Thus, the correct answer is option (C).

Describe how energy and matter move through the environment under both aerobic and anaerobic conditions.

elixir [45]

1. Describe how energy and matter move through the environment under 
A. Aerobic conditions -Photosynthesis and Respiration
-After photosynthesis occurs, the plant enters the carbon cycle. The carbon cycle uses the by-product of photosynthesis which is carbon dioxide. Carbon dioxide combined with water yields glucose (used as food) and oxygen that is released back into the atmosphere. During photosynthesis, respiration occurs which uses the oxygen and glucose to yield carbon dioxide and water which starts the carbon cycle.

B. Anaerobic conditions Muscle respiration
-This process does not require the use of oxygen.
Glucose stored in the body is used during muscle respiration to produce lactic acid and energy that is used for movement.

2. What is chemosynthesis?
- Chemosynthesis relies on chemical reactions to produce food. Inorganic compounds such as hydrogen sulfide, carbon dioxide, and oxygen enter into a chemical reaction that yields sugar, sulfur, and water, Chemosynthesis occurs most commonly in deep-sea ecosystems where the sun cannot penetrate.

3. How do chemosynthetic organisms get energy?

- Chemosynthetic organisms make use of chemicals found on the seafloor or on the sea environment. They convert these chemicals through a reaction that yields glucose (which the plants use for food) and sulfur as by-products. In turn, other organisms will use the sulfur by-product to initiate another chemosynthetic reaction to create food.

What is gained from each part of aerobic respiration?

Aneli [31]

Answer:

Cellular respiration uses energy in glucose to make ATP. Aerobic (“oxygen-using”) respiration occurs in three stages: glycolysis, the Krebs cycle, and electron transport. ... This results in a net gain of two ATP molecules. Life first evolved in the absence of oxygen, and glycolysis does not require oxygen.
