Answer:
D. XHxh and XHY
Explanation:
since this is the only answer with genes that share a common allele, the answer is D.
In order for a recessive gene to be present, the daughter must have gained the alleles of XHXH, which in this case, is a 25% chance. The other two possibilites are XHxh, XHY, and Yxh. To further prove this, a female must have 2 X alleles and to have hemophilia, they must carry 2 H's. If they were to only have one H, they would be a carrier instead of a product.
Walter Stanborough Sutton, a famous scientist from the 19th and early 20th century. He is famous for what you described, also known as the Boveri-Sutton chromosome theory, but what is the worst part is that he died young so his work was never fully done and god knows what he might have achieved in his life.
Hope this helps!

Answer:
Photosynthesis.
Explanation:
Plants are autotrophs, which means they produce their own food. They use the process of photosynthesis to transform water, sunlight, and carbon dioxide into oxygen, and simple sugars that the plant uses as fuel. These primary producers form the base of an ecosystem and fuel the next trophic levels
The study of the relationship between structures and functions is at the very heart of biology. This relationship is expressed in living beings by the adaptation of the first to the second and poses a series of absolutely fundamental problems, such as the relationship between causality and finality, analogy and homology, structural improvement and evolutionary level, etc.
For example, the structure of the hand is related to its function, thanks to the fingers and the thumb it is easy to wear and store objects.
The zigzag structure of the intestine is related to its absorption function, as this makes it possible to increase the contact surface between the alimentary bolus and the intestinal wall, and thus to increase the absorption.
Alleles. Alleles are the "same" genes, but provide a variation of the intended function.
