7 0

Answer:

Parent´s chances:

  • Mom´s chances of giving their children the big feet allele are 2 out of 2, or 100%
  • Mom´s chances of giving their children the small feet allele are 0 out of 2, or 0%
  • Dad´s chances of giving their children the big feet allele are 1 out of 2, or 50%.
  • Dad´s chances of giving their children the small feet allele are 1 out of 2, or 50%

Offspring chances:

  • The offspring have 4 out of 4 or 100% of probability of having big feet. And 0 over 4 or 0% of probabilities of having short feet.

notsponge [240]

Answer:

The osteoblasts, which should have been building the new bone

Explanation:

Bones are the one of the types of connective tissues and have hard extracellular matrix. Osteoblasts are the cells that serve in formation of extracellular matrix of bones as these cells secrete collagen fibers and inorganic salts present in the matrix of bone. Hence, if a bone is not able to heal after fracture, osteoblast cells should be checked for their activity.

How does a plant cell accomplish cytokinesis
pychu [463]

Answer:Cytokinesis in plant cells involves plants using spindle structures called phragmoplasts to carry vesicles of the cell wall material such as cellulose to the new cell plate. ... After the plate divides the plant cells into two daughter cells, the plasma membrane seals off and fully separates the two new cells. During cytokinesis in animal cells, a ring of actin filaments forms at the metaphase plate. The ring contracts, forming a cleavage furrow, which divides the cell in two. In plant cells, Golgi vesicles coalesce at the former metaphase plate, forming a phragmoplast.

Part A: A scientist examines a fruit fly gene involved with the regulation of body development. A section of the DNA sequence fo
Leokris [45]

Answer:

Part A: Thr-Leu-Val

Part B: ACC-UUG-GUU

Explanation:

When you transcribe a DNA sequence to mRNA, you need to remember that in RNA there is no Thymine (T), instead it has Uracil (U). So the base pairings would be like this compared to DNA base pairing:

DNA                RNA

A-T                  A-U

T-A                  T-A

C-G                 G-C

G-C                 C-G

Given the sequence the transcription will be as follows:

DNA :   TGG - AAC - CAA  

mRNA: ACC - UUG - GUU

Next, to translate it into amino acids, you will use the chart. Now amino acids pair in codons (3 base pairs at a time).  Let's take the first codon in your sequence:

ACC

1st  2nd   3rd

 A     C       C

Using the column on the left, find the row that matches it, so in this case A.

At the very top, there is another row of letters, looking at the row of A only, look for the column of the second base which is C.

Lastly, look at the right most column and find the letter that matches the third base within the box where A and C intersect. In this case, C is your third base.

The amino acid where all three intersect is your first amino acid which is Thr.

Just do this for the next codons and you will come up with the answer.
