Answer:

The mass of the cube would increase if the water moved into the potato cube or the mass of the potato cube would decrease if the water moved out of the potato cube after placing it in the beaker.

Osmosis can be described as a process by which water moves from an area of higher concentration to an area of lower concentration along the concentration gradient. It is a type of passive transport.

If the potato cube is placed in water, most likely the water will enter into the cell as the concentration of solutes will be more in the potato cube and the concentration of water will be less. Hence, the mass of the potato cube would increase.

Snapdragons are a type of flower. When red snapdragons are crossed with white snapdragons the resulting flowers are all pink. A

Akimi4 [234]

There is a 50% probability that the flowers of a plant with pink flowers parents will have pink flowers due to incomplete dominance.

The genotypes and phenotypes that we will employ to address this issue are as follows:

RR - Red

RW - Pink

WW - White

They would have the RW genotype as the first parent plant is pink. They would have the WW genotype because the other parent is white. When the Pink flower parents are crossed, the children that might be expected from this cross

RW x RW

The progeny will be : 1 RR (Red), 2 RW (Pink) and 1 WW (White)

This shows that there is a 50% probability that the progeny will have the RW genotype and thus the pink phenotype. Additionally, we can observe that there is a 25% likelihood that the progeny will have the WW and RR genotype and the white and Red phenotype.

Which structure forms as DNA unwinds? A. a special marker B. a complementary base C. a replication bubble D. a double helix

kozerog [31]

A replication bubble forms as the DNA unwinds.

Option C

<u>Explanation</u>:

Replication bubble is the space where the strands of double helical DNA structure are separated with the help of DNA helicase. The strands of the double helical DNA are still in the helix form on the both end of the unwinded DNA stand which gives this region an appearance of a bubble.

DNA unwinding is the first step in replication or transcription of the DNA molecule. DNA helicase separates the two types of "DNA" that are connected by hydrogen bonds with the help of ATP hydrolysis.

You are interested in studying a gene called CFTR because mutations in this gene in humans cause cystic fibrosis. You have made

Juliette [100K]

Answer: Both the mouse and human beings are encoding the proteins having similar functions.

Explanation:

The CFTR gene in the mouse and CFTR gene in the human beings encode proteins that perform similar function,this is so because if the results are same then it means that both mouse and human beings are encoding the protein that have similar function.

Option A is incorrect because both humans and mouse are eukaryotes so they have introns and because of that even if the gene sequences are different they can still encode protein.

Option B is incorrect because amino acid sequences can be similar inorder to have the similar function. If glutamic acid is replaced by aspartic acid, it won't have different function the function will remain same. So, identical amino acid sequences are not required. They can be similar too.
