Answer:
1/4
Explanation:
A heterozygous woman for both traits (RrFf) marries with a man with no freckles (ff) who can't roll his tongue (rr).
The cross is: RrFf X rrff.
The woman can produce the gametes <em>RF, Rf, rF </em>and <em>rf</em>
The man can only produce <em>rf </em>gametes.
<u>The possible offspring that can arise from the combination of those gametes is:</u>
- 1/4 RrFf Freckled, tongue-rolling
- 1/4 Rrff Freckled, unable to roll tongue
- 1/4 rrFf Not freckled, tongue-rolling
- 1/4 rrff Not freckled, unable to roll tongue
As we know,
where,
- m = mass of the object = 0.15 kg
- g = acceleration due to gravity = 9.8 m/s²
- h = height attained by the object = 4 m
let's find the potential energy of that Apple :
Under a microscope, gram-positive bacteria (when dyed with the gram stain) appear in purple-colored structures due to the peptidoglycan cell wall.
<h3>What are gram-positive bacteria?</h3>
Gram-positive bacteria are microorganisms (bacteria) that may be colored with crystal violet stain due to the presence of a peptidoglycan-based cell wall.
In conclusion, under a microscope, gram-positive bacteria (when dyed with the gram stain) appear purple-colored structures due to the peptidoglycan cell wall.
