Answer:
- The solution is hyperosmotic to the body.
- What is the concentration of nonpenetrating solutes (NP) in the solution? 500 mosmol/L
- What is the internal concentration of the body's cells? (All intracellular solutes are nonpenetrating.) 300 mosmol/L
- When the cells reach equilibrium after addition of the solution to the body, has cell volume increased, decreased, or stayed the same? increased
- Based on your answer regarding water movement, the solution was hypotonic to the body's cells.
Explanation:
A hyperosmotic (or hypertonic) solution is a solution with a greater solute concentration. If a cell is placed in a hyperosmotic solution the water will leave the cell and the cell will shrink. Conversely, a hypotonic solution is a solution that has a lower concentration of solute. If a cell is placed in a hypotonic solution the water will enter the cell through osmosis and the cell increases in size. In this case, the NaCl is a non-penetrating solute, and thereby the concentration in the body's cells maintains constant. Moreover, urea is a penetrating solute, thereby it will penetrate in the cells until the equilibrium is reached (i.e., the cells will increase in volume).
Two students gather information on the global effects of plastic found in ocean waters. Student A collected information from three peer-reviewed scientific journals on the internet while student B collected information from a local newspaper.
Which statement best describes the reliability of the students' research?
A
Student A's research is more reliable because it was gathered from peer-reviewed journals.
(Choice B)
B
Student B's research is more reliable because it came from a single source.
(Choice C)
C
Student B's research is more reliable because newspapers can only publish current research.
(Choice D)
D
Student A's research is more reliable because it came from the internet.
Answer:Student A’s research is more reliable because it was gathered from peer-reviewed journals.
Explanation:
In any experiment, reliabilty and validity is very important. The best statement that best describes the reliability of the students' research is that Student A's research is more reliable because it was gathered from peer-reviewed journals.
Reliability is simply known as an individual obtaining the same answer through the use an instrument to measure something more than once.It is the degree to which research method gives stable and consistent results.
Reliability often deals with consistency of a measure. Ita types are test-retest reliability, internal consistency, and inter-rater reliability.

If you cross a white-eyed female (ww) to a red-eyed male (WY) Drosophila fly, you will see red-eyed females and white-eyed males in the F1 generation. If you cross an F1 red-eyed female to an F1 white-eyed male, what is the approximate percentage of total progeny in the F2 generation that are white-eyed males
Answer:
25%
Explanation:
ww gives white-eye female
WY gives red-eye male
ww x WY
F1: Ww wY Ww wY
Ww - red-eye female
wY - white-eye male
Crossing the two F1
Ww x wY
F2: Ww WY ww wY
Remember that white-eye male = wY
Percentage of wY = 1/4 or 25%
Hence, the percentage of progeny in the F2 generation that would be white-eye males = 1/4 or 25%
How is stress stored
in a rock released?
Answer: The stress builds up in rocks. However, rocks eventually break, and the stored stress is released as energy in the form of earthquakes. ... The energy released during an earthquake migrates away from the focus of the earthquake (location of the first break of the rocks) as waves. These waves are called seismic waves.

The net movement of water takes place from the ____ side to the ____ side of the membrane.
The net movement of water takes place from the Hypotonic side to the Hypertonic side of the membrane.
Where does the net movement of water take place?The net Action of water is in the order of risen solute concentrations.
An easy way to imagine this rule is just that the net water move in an area of high water concentration to an area of lower water concentration.
Thus, The net movement of water takes place from the Hypotonic side to the Hypertonic side of the membrane.

Short tails (T) are dominant to long tails (t). What is the probability of a long-tailed mouse in the cross Tt x tt?
25%
50%
O 75%
O 100%
Answer:
50%
Explanation:
if you do a punnett square you get two Tt and two tt. so two tt is half, which means half will be long-tailed tt, so 50%
50% of the mouse offsprings will have long tail.
According to this question, a gene coding for tail length in mouse is involved. The allele for short tails (T) are dominant to long tails (t). In a cross between Tt (short tail) × tt (long tail), the following gametes will be produced by each parent: Tt - T and ttt - t and tCrossing these gametes in a punnet square (see attached image), the following offsprings of mouse will be produced: Tt, Tt, tt and tt. Tt (2) = Short tail mice (50%)tt (2) = long tail mice (50%)Therefore, 50% of the mouse offsprings will have long tail.Learn more at: https://brainly.com/question/478887?referrer=searchResults
