Answer:
gravity
Explanation:
the sun has a gravitational pull that keeps all the planets in orbit and prevents them from just floating away.
Answer:
The reason the planets orbit the Sun is related to why objects fall to Earth when we drop them. The Sun's gravity pulls on the planets, just as Earth's gravity pulls down anything that is not held up by some other force and keeps you and me on the ground.

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
Answers
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.

Answers
Answer:
by providing a toll-free number in case there are questions about the devices.
Explanation:
One of the best ways to make certain that this does not happen is by providing a toll-free number in case there are questions about the devices. Doing so makes sure that the customers are fully aware and understand the device and what it is doing. This prevents the customer from assimilating other benefits that they may experience which have nothing to do with the provided device into the survey and potentially contaminating the data with false feedback.

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?
Answers
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.
