iIn rabbits, floppy ears (F) are dominant over straight ears (f). A rabbit with floppy ears is crossed with one that has straight ears.
All of the offspring have floppy ears.
What is the most likely genotype of the floppy-eared parent?
FF
Explanation:
Straight-eared rabbit = ff
If all offspring = floppy, then parent must be FF
FF × ff → all Ff (floppy)

Water will leave the cell, and the cell will shrink?

Given the following DNA sequence:
TAC GGA TTT ACT
Transcribe it into mRNA.
Use a codon chart to determine the amino acid sequence.

In guinea pigs, black fur (B) is dominant over white fur (b). A black guinea pig is crossed with a white one. The litter has 50% black pups and 50% white pups.
What was the genotype of the white parent?
bb
Explanation:
Black parent must be Bb.
To get 50% white pups, white parent must be bb.
Bb × bb → 50% Bb (black), 50% bb (white)

3. A red blood cell is placed in pure water where the extracellular fluid contains 0% salt, while the intracellular fluid of the red blood cell contains 0.9% salt.
Will it shrink, swell, or remain the same?
What direction does water move, and why?
It will swell, water is moving into the cell because its moving from an area of high concentration to low concentration
