A) 1/4
B) 1/5
C) 1/8
D) 1/2
E) 0
The answer is D (1/2)
Explanation:
If each fish can possess only two allele types, a cross between a fish with allele types S1S3 and S2S4 will produce four possible offsprings using a punnet square.
S1S3 will produce S1 and S3 gametes while S2S4 will produce S2 and S4 gametes.
Each allele type confers a particular number of unit color to the fish i.e. S1 confers one unit color, S2 confers two, S3 confers 3, S4 confers 4 and so on........
A cross between S1S3 and S2S4 will yield offsprings S1S2, S1S4, S2S3 and S3S4. Combining these allele types, we will realize that only S1S4 and S2S3 will produce fishes with 5 units respectively. Hence, the probability of producing offsprings with five units of color is 2/4 or 1/2.
Answer:
XX chromosome
Explanation:
Men determine the sex of a baby depending on whether their sperm is carrying an X or Y chromosome. An X chromosome combines with the mother’s X chromosome to make a baby girl (XX) and a Y chromosome will combine with the mother’s to make a boy (XY).
On the bed because you will suffocate if you were in it
Answer:
1) The correct answer would be A. it transfers carbon to the atmosphere as carbon dioxide.
Cellular respiration refers to the set of biochemical reactions take place in a cell in order to convert the energy of glucose into adenosine triphosphate (ATP).
The carbon dioxide is released as the byproduct of the process.
C₆H₁₂O₆ + 6O₂ → 6CO₂ + 6H₂O + ATP
2) The correct answer would be D. fermentation can occur without oxygen.
Fermentation is the process which occurs in oxygen is either absent or present in very less amount.
Thus, it enables the cell to survive when oxygen is not available.
For example, in humans, the muscle cells switch to lactic acid fermentation when oxygen supply is decreased during intense exercise.
It produces very less amount of ATP as compared to the aerobic respiration.
