A student is investigating cellular transport. She fills a beaker with 250 ml of water. She places 10 drops of red food coloring

into the beaker of water and makes an observation immediately, after 5 minutes, and after 30 minutes. Her set up is shown below. image The student observes that the molecules of red dye move from an area of higher concentration to an area of lower concentration until equilibrium is reached. Which best describes the type of cellular transport that the student is investigating? A The student is investigating the passive transport of diffusion. B The student is investigating the active transport of osmosis. C The student is investigating the active transport of diffusion. D The student is investigating the passive transport of osmosis.

Answer:

The correct answer is A The student is investigating the passive transport of diffusion.

Explanation:

Diffusion is a type of transport process which helps in the transport of small molecules and gases towards their concentration gradient that"s means from region of high concentration to the low concentration region untill equilibrium is reached.

       In this question the 10 drops are red coloured food particles that are placed into the beaker, diffuses to all the regions of the beaker untill the concentration of that red colored food particle become same in all the regions to which red colored food particle diffuse.

Svetradugi [14.3K]

Answer;

Population; physiological modifications at the individual level.

The adaptation of the sled dog best describes adaptation at the population level while the dog exposed to seasonal colder temperatures has physiological modifications at the individual level.

Explanation;

-The bodies of sled dogs are covered with two coats of hair that work together to provide a double layer of warmth. The under layer is very short and the dog sheds it in the spring to keep from overheating during warmer temperatures.

-During the colder winter months, this under layer works as an insulator against the dog's skin to keep his body warm and his core body temperature consistent. This adaptation best describes adaptation at the population level while the dog exposed to seasonal colder temperatures has physiological modifications at the individual level.

Which of the following does not explain why if two people are exposed to the same high stress causing conditions, there is a lik
e-lub [12.9K]

Answer:

Probably B

Explanation:

They all explain it, honestly, but B sounds the least like an answer they would accept as true. It's also kind of sus that they have 2 different answers about reacting differently to stress, and B is definitely the least likely of the two to be correct. Sorry I couldn't be more helpful, I'm only here because I searched for the answer myself. Good luck.
