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.
when is hypothesis accepted as a theory by the scientific community
Answer:
A hypothesis is an idea that hasn't been proven yet. If enough evidence accumulates to support a hypothesis, it moves to the next step — known as a theory — in the scientific method and becomes accepted as a valid explanation of a phenomenon.
How is the scientific theory developed
Answer:
The development of scientific theories A scientific theory is a general explanation that applies to a wide range of situations and examples. As technology develops more data can be collected and new types of observations made. A hypothesis is a testable explanation of an observed event.

After transcription, the new mRNA strand travels to the cytoplasm and over to the ___________ where the genetic code will be translated into amino acids.
nucleus
cell membrane
ribosomes
golgi bodies
After transcription, the new mRNA strand travels to the cytoplasm and over to the RIBOSOMES where the genetic code will be translated into amino acids.
During gene transcription, a specific fragment of DNA called gene is used to produce a complementary messenger RNA (mRNA) sequence in the cell nucleus.
Subsequently, this mRNA travels to the cytoplasm where it is used as a template to synthesize a polypeptide chain in the ribosomes by a process called translation.
Ribosomes are protein factories that read the genetic code in the mRNA sequence (i.e., the codons of the mRNA) to translate it into the correct order of amino acids of the protein.
In conclusion, after transcription, the new mRNA strand travels to the cytoplasm and over to the RIBOSOMES where the genetic code will be translated into amino acids.

C.Photosynthesis requires carbon dioxide and cellular respiration releases carbon dioxide.
D.Photosynthesis requires oxygen and cellular respiration releases oxygen
Answer:
C.C.Photosynthesis requires carbon dioxide and cellular respiration releases carbon dioxide
Photosynthesis requires carbon dioxide and cellular respiration releases carbon dioxide. Hence, option C is correct.
What is cellular respiration?The process through which organisms use oxygen to break down food molecules in order to get chemical energy for cellular processes is known as cellular respiration. The cells of animals, plants, and fungi, as well as those of algae and other protists, all engage in cellular respiration. It takes place in mitochondria and cytoplasm.
Cellular respiration serves the straightforward objective of giving cells the energy they require to function. Food would be completely useless if living beings couldn't obtain the energy they required from it.
Anaerobic (without oxygen) and aerobic (with oxygen) cellular respiration are both possible (without oxygen). During aerobic cellular respiration, glucose and oxygen combine to create ATP, which the cell can utilize. As byproducts, carbon dioxide and water are produced.

Answer:
Muscle cells
Explanation:
Muscle cell have highest number of mitochondria. Thus, option C is correct.
What is mitochondria?
Mitochondria are the power house of the cell, membrane-bound organelles present in the cytoplasm of both plant and animal cell.
It produces adenosine triphosphate (ATP) by breaking down of nutrients. Cellular respiration also occur in mitochondria.
Structurally it comprises three parts such as an outer membrane, an inner membrane, and matrix part which is a gel like structure.
The outer membrane separated by the intermembrane space from the inner membrane and it is composed of proteins and phospholipid layers
The outer membrane has a large number of special proteins called as porins.
It is also involved in regulation of the metabolic activity, promotion of cell growth, multiplication, detoxifying ammonia, apoptosis, make various hormones like testosterone and oestrogen, cellular differentiation, cell signalling, cell senescence, cell cycle control.
