Answer:
possible differences resulting from using two different breeds of dog
Explanation:
The question above presents a scientific experiment carried out by students Pablo and Johanna from the biology course. In this experiment, they both compare the results of different diets on their dogs. Up to this point, the experiment was being established correctly, since the variables independent (the composition of the dogs' diet) and dependent (the influence of the diet on the dog) were defined. However, these students made a mistake in using dogs of different breeds.
In an experiment, everything must be very controlled and the treatments must be exactly the same. In the above case, the dogs are the treatments and the fact that they belong to different breeds, means that the results of the experiments can present significant differences, not providing a correct conclusion of the experiment.
The probability of obtaining a yellow-fruited plant from the cross is ¼ or 25%.
<h3>WHAT IS A HETEROZYGOUS CROSS</h3>
A heterozygous cross is a cross between two individuals that are heterozygous for two genes.
According to this question, white (W) fruit color is dominant over yellow (w). If two white-fruited individuals with genotypes that are unknown are crossed i.e. Ww × Ww.
The offsprings of this cross are as follows:
Therefore, the probability of obtaining a yellow-fruited plant from the cross is ¼ or 25%.

Answer:
<h3>Yes, Passive transport can occur in dead cells.</h3>
Explanation:
For passive transport to occur, a concentration gradient has to be formed across a permeable or semi-permeable membrane. If the cell membrane of the dead cell, which is a semipermeable membrane, is intact and a concentration gradient has formed on both sides, passive transport can occur.
A concentration gradient is the difference in the concentration of solute molecules across the membrane. Passive transport will allow solute molecules to travel from the higher concentration of the solute to the lower concentration across a membrane till equilibrium is reached, that is, both the sides of the membrane has equal concentration of the solute.
The transport of the solvent can occur as well, from higher concentration to lower concentration.
