Answer:
A. parents: Hh and Hh
B. chances of being a carrier: 50%
C. 50%
Explanation:
A. Since hemophilia is a recessive trait, both parents must carry the recessive alelle for it to show through in the child. However, we know both of them are phenotypically normal, meaning a dominant trait (not hemophiliac, H) is masking the recessive trait (hemophiliac, h)
B. The options the woman has when you create a punnet square with her parents genotypes are HH (doesn't have any hemophilia, because hemophilia is recessive, so represented with a lower case h) Hh (there is twice the likeliness she is an Hh since it occurs two times when you combine her parents genotypes. Hh means she is a carrier, but does not have the trait) and hh (meaning she definitely has it). So there is four options, two of which mean carrier, meaning she has a 50% chance of being a carrier.
C. genotypes of the parents:
mom: Hh
dad: hh
when you create their punnet square, you will get two occurrences of Hh and two occurrences of hh. Remember that hh means hemophilia. This means the child has a 50% chance of having hemophilia.
The statement best that explains why cells were observed in more detail using compound microscope than a simple microscope is : compound microscope has greater magnification ability than the simple microscope .
This will allow us to observe the subject with a much smaller size, making it easier for us to observe the detail

Answer:
<u>The enzyme's active site binds to and stabilizes the transition state, which decreases the activation energy of the reaction.</u>
Explanation:
Enzymes are complex multi-folded forms of proteins - they promote chemical reactions in biological processes.
Typically, molecules collide at random, and complex chemical reactions require the right molecular orientation and energy to react (breaking and forming bonds).
Enzymes lower energy needs by providing an alternative reaction pathway and stabilize and maintain the molecules in their intermediate forms called transition states.
The surface layer of the water freezes solid creating a barrier that insulates the ice below so that it keeps a steady temperature usually a few degrees above freezing (32 degrees).
