A pea plant that has round seeds has the genotype Rr. It is crossed with a pea plant that has wrinkled seeds and the genotype rr

. What is the possibility that the offspring will have wrinkled seeds

The correct answer is 50%, or 1/2. We know that round seeds are dominant, since the round pea plant has a genotype of Rr and the wrinkled pea plant has a genotype of rr. If it helps, draw a Punnett square with the two genotypes.

   R  r
r
r

The square works exactly like a coordinate grid. Combine the letters above and beside whichever of the four spaces you chose to find the genotype for that space.

   R  r
r Rr  rr
r Rr  rr

Therefore, 2 out of 4 of the pea plants have round seeds, since a genotype of Rr means that a plant will have round seeds, and 2 out of 4 will have wrinkled seeds, since a genotype of rr means that a plant will have wrinkled seeds. 2/4 simplifies to 1/2, or 50%. Therefore, there is a 50% chance that the offspring will have wrinkled seeds.

Hope this helps!

HELP PLEASE
Alex

Answer:

I can’t answer all of them, but I’ll answer the oxygen ones.

The mitochondria uses oxygen. In mitochondria, this process uses oxygen as a waste product. They are organelles that act like a digestive system which takes in nutrients, breaks them down, and creates energy rich molecules for the cell.

I hope this helps, even though I only answered 3 of your questions!!

The concentration of salt is higher inside a cell than outside the cell. The concentration of water inside the cell is lower tha
asambeis [7]

Answer:

C. Water will move into the cell through osmosis. The salt and water concentrations will become similar inside and outside the cell.

Explanation:

Osmosis is the movement of water from its higher concentration to the lower concentration through a semi permeable membrane. Here, the cell have higher salt concentration and lower water concentration as compared to its outside. Since cell membrane is semi permeable, salt cannot pass through it. So, water will move into the cell through osmosis to equalize the salt and water concentration on either side of cell membrane.
