Which of the following statements tells how facilitated diffusion differs from
simple diffusion?
A. Particles move through cell membranes without the use of energy by cells.
B. Particles tend to move from high concentration to lower concentration.
C. Particles move within channel proteins that pass through cell membranes.
D. Particles tend to move more slowly than they would be expected to move.
Answers
Answer:
I think its C but I am not sure, I hope this helps :)
Explanation:
The statement 'particles move within channel proteins that pass through cell membranes' indicates the reason for which facilitated diffusion differs from simple diffusion (Option C).
Diffusion (both facilitated diffusion and simple diffusion) refers to the movement of substances across biological membranes from an area of high concentration to an area of low concentration.
Facilitated diffusion and simple diffusion are two types of passive transport that do not require energy to move molecules/ions in favor of a concentration gradient.
In facilitated diffusion, specific membrane proteins known as carriers or channels help to the movement of substances in favor of a concentration gradient.
Conversely, in simple diffusion, small molecules (e.g. CO2 and oxygen) freely diffuse across a selectively permeable membrane in favor of a concentration gradient.
In conclusion, the statement 'particles move within channel proteins that pass through cell membranes' indicates the reason for which facilitated diffusion differs from simple diffusion (Option C).

Explanation:
What if climate change is self-sustaining? This is already the case, for example, with melting arctic sea ice. This reflects solar radiation, which allows the ocean, located under the ice, to stay cold. But when sea ice melts, the ocean absorbs heat from the sun, which melts more ice. In general, it is difficult to predict the tipping point where such a feedback loop will engage.
Spread over more than 23,000,000 km2, at the top of the globe, permafrost (permanently frozen ground) could enter such a vicious circle. Normally, up to 4 m of soil and plant debris cover the permafrost. This top layer (called the active layer) normally melts every summer, and freezes in winter. It thus protects the permafrost from the rise in heat outside. But in the spring of 2018, a team working at a research station in Tchersky, Russia, discovered that near-surface land had not frozen over at all during the long, dark polar night.

The sun is brighter over the open ocean.
There is more nitrogen by the coral reefs.
There is more plankton by coral reefs.
Answers
Answer: There is more plankton by coral reefs.
Explanation: Plankton tend to hang around surface waters which coral reefs also grow in. And most of that Plankton are plants that need more sunlight. So the sun would be brighter in shallower waters rather than open ocean.

thymine, guanine, guanine, and cytosine
thymine, adenine, adenine, and cytosine
Answers
Answer:
thymine, guanine, guanine, and cytosine
Explanation:
The order of the bases on the opposite strand of DNA should be Thymine, Guanine, Guanine and Cytosine.
DNA and complementary base pairingThe deoxyribonucleic acid (DNA) is a double helix composed of two long chains of sequential nucleotides.
In DNA there are four classes of nucleotides, each containing one different nitrogenous base (i.e., Adenine, Guanine, Cytosine, Thymine).According to the base pair rules of complementarity, Adenine always pairs with Thymine, whereas Guanine always pairs with Cytosine.In conclusion, the order of the bases on the opposite strand of DNA should be Thymine, Guanine, Guanine and Cytosine.

Answer:
Acids are sour, gives burning sensation, generally sticky, reacts with metals to produce hydrogen gas. Although bases are opposite as they are bitter, generally odorless (except ammonia), they are slippery; bases react with fats and oils. In phenolphthalein, indicator acids remain colorless, and base gives pink color.
