True or false: Photosynthesis is an important part of the carbon cycle.
А
True
B
False

Answers

Photosynthesis is an important part of the carbon cycle - True.

may this helps you

bye

It is true that photosynthesis is an important part of the carbon cycle. The correct option is A.

What is the role of photosynthesis in carbon cycle?

Photosynthesis is the process by which plants convert sunlight, water, and carbon dioxide into oxygen and sugar energy.

Plants absorb carbon dioxide and sunlight during photosynthesis to produce fuel glucose and other sugars for plant structure construction. The fast (biological) carbon cycle is built on this process.

The carbon cycle includes cellular respiration and photosynthesis. The carbon cycle refers to the processes by which carbon is recycled in the biosphere.

While on the other hand cellular respiration emits carbon dioxide into the environment, photosynthesis absorbs carbon dioxide.

Carbon dioxide is removed from the atmosphere by photosynthesis and replaced by cellular respiration. Photosynthesis takes oxygen from the atmosphere and cellular respiration replenishes it.

Thus, the correct option is A.

4. Which of the following is NOT true of the digestive system? a. The stomach contains acids to break down food b. Digestion begins with enzymes in the stomach c. The large intestine absorbs water from the digestion of nutrients d. The small intestine does most of the absorption of nutrients

Answers

Answer:

B. Digestion begins with enzymes in the stomach

Explanation:

The digestive process starts in your mouth when you chew. Your salivary glands make saliva, a digestive juice, which moistens food so it moves more easily through your esophagus into your stomach. Saliva also has an enzyme that begins to break down starches in your food.

The following is a growth curve of bacteria. What type of growth curve is pictured? A) linear growth B) logistic growth C) exponential growth​

Answers

Answer:

C) exponential growth​

In the given figure, exponential growth curve is pictured.

What is exponential growth?

It is the pattern of data, which demonstrates greater enhancements with passing time, giving rise to a curve of an exponential function. During the growth cycle of bacteria, the cells of bacteria goes through different phases, that is:

Lag phaseExponential phaseStationary phaseDeath phase

In the case of bacteria, the cells enter the log or the exponential phase after the lag phase. This is the time when the cells get differentiate by the process of binary fission and double in numbers after each generation time.

In this pattern of growth, the metabolic activity is high as RNA, DNA, the components of the cell wall, and other substances essential for growth are generated for differentiation.

Thus, the pattern of growth demonstrated in the given figure is exponential growth.

A food web is more realistic because a snake eats more than just frogs. The correct option is B.

What is a food web?

A food web is a network of interrelated food chains that represents the movement of materials and energy within an ecosystem. In a food chain, the various arrows symbolize the various species that are being consumed by one another and so represent the flow of energy. Additionally, it shows that an animal can eat a variety of foods.

Food chains that are linked together form food webs. In a food chain, arrows point from the organism being eaten to the organism eating it.

The energy flow in a food web is depicted by arrows. Food webs display every form of eating in an environment.

Thus, the correct option is B. eats more than just frogs.

Four students provide their teacher with an explanation of why photosynthesis is considered a chemical change. Luke: Photosynthesis is considered a chemical change because the CO2 molecules disappear and the O2 molecules reappear. Jackie: I know that photosynthesis is a chemical change because all of the reactants undergo a state of matter change and are all present as a product. Tara: Through photosynthesis, the CO2 and water are changed into new substance, glucose, therefore it is considered a chemical change. Skyler: Photosynthesis is a chemical change because solar energy is required. Which student provides the best explanation of why photosynthesis is a chemical change

Answers

Answer:

The best explanation was provided by the student Tara who said: "Through photosynthesis, the CO2 and water are changed into new substance, glucose, therefore it is considered a chemical change".

Explanation:

A chemical change is one which is not easily reversible and which results in the formation of new subsatances.

For example, in photosynthesis,a new substance, glucose is formed from the original substansubstances, carbon dioxide and water. Also, the reverse process of the formation of carbon dioxide and water from glucose is not easily obtained in plants.

From explanations provided by the students :

Luke does not give any explanation of the process but only an observation

Jackie's explanation does not state the main reason why a chemical change differs from a physical one.

Tara, gives the best explanation as the reason why a change that occcured is a chemical change is clearly stated.

Skyler does not state the main reason why photosynthesismis a chemical change as well, because even physical changes like evaporation of water involves solar energy.

Or, if you choose an ocean ecosystem, identify its geographical area and depth. Keep in mind that deep-sea organisms live in a completely different environment than surface aquatic organisms.


Next, conduct research on the following conditions in the ecosystem you chose. They influence the types of organisms that can live there.


geographical features

temperature

depth/light availability

salinity

pH

unique features that contribute to the ecosystem, such as other bodies of water that connect to it, unusual chemistry, and climate
