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.
Answer:
Explanation:
a simple way to look it it is:
Hypertonic would be when the insides are shrunk (arrows point out)
Hypotonic when its full (Arrows point in)
Isotonic is at balance (arrows point out and in)
osmotic: the passage of a liquid through a membrane from a less concentrated solution to a more concentrated one (equal concentrations)
Although I'm not sure which image I'm supposed to be describing, but hope it helps you figure out the answer
Answer:
a dominant mutation
Explanation:
A monohybrid testcross is a cross-breeding experiment used to determine if an individual exhibiting a dominant phenotype is homo-zygous dominant or heterozygous for a particular phenotypic trait (in this case, wing length). In a monohybrid testcross, a 1:1 phenotypic ratio shows that the dominant parental phenotype was a heterozygote for a single gene that has complete dominance. Moreover, a 3:1 ratio in the F2 is expected of a cross between heterozygous F1 individuals, which means that 75% of individuals with short wings have the dominant allele that masks the expression of the long-wing trait (i.e. the recessive allele).
Meiosis because it is the process of gamete formation, which is gametogenesis
It is b. If I am wrong I am sorry
