Explain the role of cellular respiration in a cell.

Answers

Answer:

Every cell performs a type of cellular respiration as it is required to produce energy. The point of cellular respiration is to turn high-energy molecules, know as glucose, into ATP, a form of usable energy. There are two types of respiration, aerobic and anaerobic. Aerobic goes through 3 stages and produces the most ATP by using oxygen and releasing carbon dioxide. Anaerobic does the same job but only uses one stage and produces much less ATP. This process gives the cell energy and continues the carbon cycle.

Which phase of the cell cycle is the least common process of mitosis and what could be the reason?

Darwin presented a hypothesis about how evolution takes place. Now this hypothesis has become a theory. What caused the idea to become a theory? A. Darwin shared his ideas with others, and many scientists have performed experiments that support this idea. B. Darwin is well respected, and scientists honor his work by referring to his idea as a theory. C. Darwin performed an experiment that supported his hypothesis. D. Darwin convinced everyone around him that it was a good idea.​

Answers

Answer:

C. Darwin performed an experiment that supported his hypothesis.

Explanation:

Darwin believed that his experiment, which was comparing the finch's beaks from Galapagos Archipelago, in which there was variation between the size and shape of beaks, as the basis in which he believed evolution was correct. However, variation does not mean evolution, and evolution, in which it calls for a chain of events to create beneficial traits successively, is nigh impossible to occur in the real world. Again, that is not to say that there is no such thing as variation, in which there is, in which people or animal groups adapt to their natural habitat. However, to state that adaptation is proof that a species becomes another is to go out on a limb, and current failures of "new species" (in that it originates from today's day and age, rather then discovered) to emerge is proof of such.

If the stomata remain closed due to water loss, what happens to the concentration of CO2 and O2 in the leaf

Answers

Answer:

Fixation of oxygen occur instead of carbondioxide.

Explanation:

If the stomata remain closed due to water loss, the concentration of carbondioxide decreases and oxygen increases in the leaf because of the fixation of oxygen instead of carbondioxide by rubisco. The plant takes carbondioxide from the atmosphere when the stomata is open so when the stomata is closed there is no other way for getting carbondioxide into the leave so the oxygen is now being fixed by our rubisco enzyme to that five-carbon compound instead of carbon dioxide.

A microbiologist is conducting a research project on chemolithoautotrophs. This means that the investigator is examining certain aspects of a bacterium that is a purple nonsulfur bacteria which depends on light. uses light as its energy source and carbon for organic compounds. can oxidize inorganic molecules such as ammonia and sulfur for energy. can use the energy from sunlight to build organic molecules from carbon dioxide. obtains carbon from organic molecules.

Answers

Answer:

uses light as its energy source and carbon for organic compounds.

Explanation:

The purple non-sulfur bacteria which depends on light produces organic food  just like plants through the process of photosynthesis. The purple non-sulfur bacteria uses carbondioxide and water with sunlight produces oxygen and glucose which is an organic compound. So that's why purple non-sulfur bacteria is also known as phototrophic means organism that produces their own food through photosynthesis.

The most direct method by which an ion or molecule can move across a cell membrane is by ____________.A. using an integral protein.B. a sodium-potassium pump.C. simple diffusion. D. active transport.E. osmosis.

Answers

Answer:

C. Simple diffusion

Explanation:

Simple diffusion from a high to low concentration is the most direct method that ions or molecules can move across a cell membrane.

Through this method, no proteins are required for transport, and no energy is used.

The ion or molecule being transported directly moves across the cell membrane, without any other factors involved.

So, the correct answer is C. Simple diffusion

Every day we make choices that can potentially affect our environment. For example, we may toss a plastic drink bottle into the nearby trash because it’s more convenient than walking all the way to the recycling bin. Think about three choices you made this week that could have affected the environment. Did your choices have a positive or a negative effect on the environment? Explain your reasoning.

Answers

First, I chose to put a Chipotle container into the trash, instead of the recycling. This wasn’t the best decision, because it could have gone to the recycling and helped others.

Secondly, my family owns a compost bin and compost machine that helps compost vegetable waste, fruit scraps, coffee grounds, and other compostable items. Choosing to do this helps the environment in many ways.

Thirdly, I picked up many aluminum cans on the side of the road to crush and collect. After several months of collecting them in a container, my family and I bring them to a place that recycles and reuses metals and aluminum.

The three choices that could have affected the environment are as follows:

Utilization of plastic to make it easy for carrying objects.Plants trees in order to build a green environment. Overdependency on vehicles rather bicycles and pedestrians.

What is Environment?

The environment may be defined as anything which is present in the surroundings of living organisms. This environment basically has two types of factors biotic and abiotic factors.

In the above three choices, building a green environment has a positive effect on the environment. It may also affect living organisms positively. While the rest of the two may stimulate a negative impact on the environment by increasing the levels of carbon dioxide by liberating emission and non-biodegradable plastics.

Therefore, the three choices that could have affected the environment are well mentioned above.
