A student claims that membrane transport 4 is the only type that represents active transport. Is the claim made by the student correct? In a dog breed, there are three types of natural hair textures: curly, straight, and wavy. If a curly-haired dog (dd) and a wavy-haired dog (Dd) have puppies, what percentage of the puppies will have wavy hair?
Understand the Problem
The question is asking whether the claim made by a student concerning membrane transport 4 as the only active transport is correct and follows up with a genetics question about the percentage of puppies with a specific hair texture. This requires knowledge in both cell biology and genetics.
Answer
The claim is incorrect; 50% of puppies will be wavy-haired.
The student is incorrect. Membrane transport 4 represents active transport, but it isn't the only type. Regarding the dog coat question, 50% of the puppies will have wavy hair.
Answer for screen readers
The student is incorrect. Membrane transport 4 represents active transport, but it isn't the only type. Regarding the dog coat question, 50% of the puppies will have wavy hair.
More Information
Active transport requires energy, typically seen in processes like sodium-potassium pumps. For dog hair texture, the combination of alleles dictates the offspring's hair type.
Tips
Ensure understanding of what constitutes active transport. When solving genetic problems, correctly set up Punnett squares.
