Why do the plant and animal cells SHARE some levels of classification?
Why are some levels of classification DIFFERENT?
Answer:
Evolution and adaptation
Explanation:
I would say that the first reason for animal and plant cell to be alike in some ways is for the main reason of us being derived from the same original source but the difference between the cells comes with the organisms adaptation to the different environments. hope that helps!

How is facilitated diffusion different from simple diffusion? a) facilitated diffusion requires the use of a transport protein and energy in the form of ATP b)facilitated diffusion and a simple diffusion both requires energy but facilitated diffusion uses a transport protein c)facilitated diffusion requires a transport protein d)Facilitated diffusion requires energy in the form of ATP
Answer:
a) facilitated diffusion requires the use of a transport protein and energy in the form of ATP
Explanation:
Diffusion is defined as the movement of substances from high to lower concentration across a potential gradient. Facilitated diffusion and simple diffusion are two different types of diffusion.
Simple diffusion does not require energy while facilitated diffusion requires energy in the form of ATP. Facilitated diffusion is a type of passive transport in which transport protein and energy is used in the form of ATP that allow the movement of substances across the cell membrane. There are majorly three types of proteins involved in facilitated diffusions such as channel proteins, carrier proteins, and gated channel proteins.
While in simple diffusion, pumps are used to move the substance across the membrane.
Hence, the correct answer is "a".
Answer:
a) facilitated diffusion requires the use of a transport protein and energy in the form of ATP
Explanation:
In simple diffusion, the molecules can pass only in the direction of concentration gradient. In facilitated diffusion, the molecules can pass both in direction and opposite of the concentration gradient. Simple diffusion permits the passage of only small and nonpolar molecules across the plasma membrane.

Which of the following is the correct equation for PHOTOSYNTHESIS?
CO2 + O2 + H20 --> Light+ glucose
CO2 + glucose + H20 --> O2 + light
CO2 + light + H2O --> O2 + glucose
O 02 + light + H2O --> CO2 + glucose
Answer:
CO₂ + light + H₂O --> O₂ + glucose
General Formulas and Concepts:
Photosynthesis is for plants and they use water, carbon dioxide, and energy to make oxygen and sugar.
Explanation:
The general formula for photosynthesis is always:
6CO₂ (g) + 6H₂O (l) + light (energy) → C₆H₁₂O₆ (s) + 6O₂ (g)

Which statement does NOT accurately describe eukaryotic and prokaryotic cells?
Answer:
You did not provide any options so i will give some facts that will hopefully help you in figuring out the correct answer.
For prokaryotic cells, the cell wall is a tough, fibrous layer that protects the cell and gives it shape and rigidity.
Prokaryotic cells are found in the domain(s) Bacteria and Archaea.
True: Prokaryotic cells have nucleoids and eukaryotic cells have nuclei.
A prokaryotic cell is distinct from a eukaryotic cell because a prokaryotic cell lacks _a nucleus_.
There is only _1_ eukaryotic domain, it is Eukarya.
do gases sink or float
answer
the density of gases depends upon the temperature. The higher the temperature, the more the molecules are spread out and the lower the density as shown in the graphic on the left. The result is that warm gases rise and cool gases sink.
Explanation:
Answer:
It depnds on howw dense they are
Explanation:
If they are denser than air then they sink. If they are less dense then they float.

Although Arroyo does not mention the term "watershed," it was discussed in the unit as being closely related to and impacted by drought and floods. Please discuss how the watershed relates to drought and heat. How might Arroyo have integrated the term watershed into her talk?
Answer:
Arroyo integrated the term “watershed“ by saying that Oxfam and Swiss Re with the Rockefeller foundation are helping farmers building hillside terraces to conserve water and they are also providing for insurance when the droughts do come.Water shed relates to drought and heat because it will suffer and there would be less water to fill surface water resources and less water to make its way through the earth and into groundwater reservoirs.

Stem cells can become any type of cell in the human body, making them ideal for many types of therapies. One area of possible use is in brain cell transplants that could help people with spinal cord injuries and neurodegenerative diseases such as Parkinson's disease. Even though there is great potential for helping people, what is one ethical issue that could arise from the use of stem cells?
Answer and Explanation:
Stem cell transplant in the brain is not clinically approved yet. The only scientific and ethical via to generate a treatment is through an approved clinical essay. Clinical investigation in the stem cell transplant involves an important and long study of the risks and benefits relationship before the treatment begins. However, the transplant is an invasive method directed to the brain that might result in very serious neurological damage, which can not be predicted by the preclinical analysis. Some of the patients treated have shown positive effects, but some others have poorly responded to the treatment. Also, some long-term studies suggest that these transplants might still result in the evolution of the disease together with secondary effects. Also, the transplant might originate cancerous cells, tumors, inadequate cell migration, immune rejection, bleeding during surgery, and post-surgical infection. Using stem cells for clinical use requires first an ensure that the treatment will result in a long-term improvement of motor function along with a relief of drug resistance symptoms in animals.
