Answer:

Wrinkled peas need to have genotype rr, since the wrinkled trait (r) is recessive

R is the dominant allele ( codes for round seeds). The dominant allele will be “dominant” or expressed over the recessive allele which is r or wrinkled. So with Rr the dominant allele/ trait masks the recessive trait

When an orginism is repredused by budding, how does the new organism start growing?

Finger [1]

Budding is a type of asexual reproduction where the new organism (offspring) grows as an outgrowth from the body of the parent. Here, the new individual starts growing as a small body on one side of the parent organism and continues growing in size while still attached to the parent.

Early on, it appears as part of the parent given that it does not detach until it has grown further. Ultimately, the new individual, which resembles the parent, detaches and becomes an independent organism.

What is your opinion about minor children (under the age of 18) donating one of their kidneys for their brother or sister? Write

lys-0071 [83]

I think that minor shielded should not donate one of their kidneys because some genetic kidney diseases won’t have started to cause symptoms yet in young children and so it’s hard to know if their kidneys may be affected by diseases

Kyle concludes that the cell must be a plant cell. How does Kyle know that the cell is a plant cell and not an animal cell?

Mnenie [13.5K]

Kile should know the answer because of the morphology (part of biology that studies the estructure and the form of something). The plant cell presents a rectangular form, while the animal's cells presents a round form.

There are other main differences. As their parts and the size. Before I explain that remember that a cell can be of two types eukaryotic (cell with nucleus) and prokaryote (cell with no nucleus). In the other they can be neurons, nefrons, etc...

The plant cell contains for example chloroplasts, cell wall and vascuoles; while animal's don't. Both of them have nucleus, cell plants are generally larger than animals. Those are the main differences.

Thankyou.

Sorry for my bad english, It's not my native language.

You have a 15kb plasmid. EcoRI cuts the plasmid into 7kb and 8kb pieces, and BamHI cuts the plasmid into 1kb and 14kb pieces. If

Harman [31]

Answer:

a. Bands at 1kb, 6kb and 8kb

Explanation:

The EcoRI and BamHI are the restriction enzymes which cut the DNA sequence especially a plasmid at specific sites called the restriction sites.

The restriction enzymes produces bands of specific length therefore these restriction enzymes are used to estimate the approximate length of the DNA.

In the given question, the

1. EcoRI- produces two strands of 7 kb and 8 kb

2. BamHI- produces two strands of 1kb and 14kb

This shows that the length of DNA sequence is 15kb

But when the DNA strand are digested with both the enzymes simultaneously then it will produce three bands as:

i) 14 kb can be broken down in 2 bands of 6 kb and 8 kb

ii) 1 kb band is already produced by the Bam HI.

This shows that 1+6+8= 15 kb

Thus, Option-A is correct.
