Diffusing molecules move ________ until they are ________. Through channels of active transport proteins; evenly distributed up
koban [17]

Answer;

-Down the concentration gradients; evenly distributed

Diffusing molecules move down the concentration gradients until they are evenly distributed.

Explanation;

Diffusion is the movement of particles from an area of higher concentration to an area of lower concentration.

-Whenever a substance exists in greater concentration on one side of a semipermeable membrane, such as cell membranes, any substance that can move down its concentration gradient across the membrane will do so. If the substances can move across the cell membrane without the cell expending energy, the movement of molecules is called passive transport.

-The mechanism of molecules moving across a cell membrane from the side where they are more concentrated to the side where they are less concentrated is a form of passive transport called simple diffusion.

Which of the following best describes the effect the moon has on the tides?
Anit [1.1K]

Answer:

A The gravity of the moon pulls the ocean, which causes the tides.

Explanation:

Well all of the other answers are just completely different.

if the moon is invisible tides cannot be seen, but why is it at night it is called high tide. B is very odd because many surfing events happen during the day.

It is A because it contains the most context, because it is the only reliable and realistic option, because when the moon is up, and the sun is down, it causes stronger waves

A rat population has an average weight gain between weeks 2 and 4 of 10 grams, and the narrow-sense heritability of the weight g
madam [21]

Answer:

The correct answer is - 11.25

Explanation:

Given:

Average weight gain between weeks 2 and 4 = 10 grams

The narrow-sense heritability of the weight gain between 2 and 4 weeks

= 25%

Then

Average weight gain would be expected among the offspring of parents whose average gain was 15 grams-

by the formula:

Average weight gain between weeks + (h) (Average weight gain between weeks - parents average gain )

= 10 + 0.25 (15-10)

 = 10 + 0.25 (5)

= 10 + 1.25

  = 11.25

Thus, the correct answer is - 11.25

If a person had a low level of neurotransmitters, how could this affect the person?
AveGali [126]

Answer:

B

Explanation:

Neurotransmitters such as acetylcholine, epinephrine are important at a neuron-neuron junction called synapses. When an impulse reaches the end of one neuron, at the synapse, it causes the release of neurotransmitters from synaptic vesicle that diffuse across the synapse and when they bind to their reports on the other end. An impulse is then generated on the subsequent neuron that travels down the axon to the next synapse.

Net production efficiency (NPE) is defined as the product of 100 and the quotient of net consumer productivity and assimilation.
lutik1710 [3]

Answer:

The assimilation of the primary consumer is 5000 kcal/m2/yr, option C.

Explanation:

From the information in the question, the Net Production Efficiency, NPE can be calculated using 100Cp/AS.

Where CP is the consumer productivity and AS is the Assimilation.

Therefore, 20 = 100 x 1000/AS

AS = 100,000/20 = 5000 kcal/m2/yr. Option C.
