Which of the following is a true statement?
A. Disruptions in an ecosystem are normal and natural changes.
B. Disruptions in an ecosystem are caused by both human activity and environmental disturbances.
C. Ecosystems are complex, interactive systems that include both biotic and abiotic components of the environment. D. All of these are true statements.​

Answers

Answer 1

Answer:

All the statements are true and the correct option is;

D. All of these are true

Explanation:

Ecosystems change over time. ... Sudden disruptions such as volcanoes, floods, or fires can affect which species will thrive in an environment. Other disruptions are caused by human activities

An ecosystem ecosystem is an area where a community living (biotic) and non living (abiotic) things such as plants, animals, other organisms, landscape, natural sources and weather interact to create an apparently sustainable system

An ecosystem undergoes several changes over time due to environmental disturbance which results in the variation of the ecosystem's structure and change rate due to the natural disturbance and/or human activity

Therefore all the statements are true.

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.

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.

Explain what would happen to a person if they eat/drink something that their body does not have an Enzyme for?

Answers

Answer:

People with lactose intolerance may have a variety of symptoms. It all depends on how much dairy or how many milk-containing foods the person eats and how little lactase the body produces.

Usually within 30 minutes to 2 hours after eating, someone with lactose intolerance will experience nausea, stomach cramps, bloating, gas, and diarrhea. This can be unpleasant, not to mention embarrassing if you're at school or out with friends.

Because many people may think they're lactose intolerant when they really aren't, it helps to see a doctor who can diagnose the condition correctly and advise you on ways to manage it.

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.
