Pls help!!! osmosis help needed!!
galina1969 [7]

Answer:

1. 10% 2. 90% 3. 80% 2. Yes 3. Into 3. Swell 6. Hypotonic

Explanation:

1. Given the image, it shows there is 10% glucose outside the cell.

2. Because there is 10% glucose outside the cell, you can automatically conclude that there is 90% of water outside. (You want it to equal to 100%. So, 10 + 90 = 100)

3. Given 20% glucose inside the cell based on the image, you can conclude that there is 80% water inside the cell.

2. Yes, osmosis will occur. Osmosis is the movement of water from a higher concentration to a lower concentration. In this case, there is more water <em>outside </em>the cell than in. So, yes, osmosis will occur.

3. The water will move into the cell (There's less water inside, and more outside, so of course, the water will move in).

3. The cell will swell, since water is getting moved in.

6. This is a hypotonic solution. Definition of a hypotonic solution: The concentration of solutes outside the cell is less than that of water. Hypotonic solutions always <em>swell, </em>as water moves into it.

Hopes this helps!^^ I tried the best I could at explaining.

Which guinea pig parent(s) in Punnett Square B is homozygous? Which is heterozygous? Explain how you know.
ArbitrLikvidat [17]
You did not provide an image for me, but I can explain.

Homozygous, with the root homo, means same. Therefore, a guinea pig parent with homozygous traits would have the traits being the same - either both recessive or both dominant, ie TT, tt.

Heterozygous on the other hand means different, therefore the traits would be one dominant and one recessive - for example, Tt.

If for the punnet square it has different traits (Combo RB for red and black or combo RW red white for like fur color) than heterozygous would be any that isn’t like TT or tt or any other letters used.

Hope this helps!
