Answer:
a.There are three signaling pathway
1- Reception in which molecule binds to receptor
2- Signal transduction in which activation of intracellular pathway and enzyme occur.
3- Cellular response in which specific response of cell occur according to receptor and ligand.
b. Three types of receptors are
1- autocrine
2- paracrine
3- endocrine.
Explanation:
autocrine receptors are signaling pathway in which cell releases its molecule and bind to its own cell receptor example cancer cells while paracrine in which ligand binds to other nearby cell receptor and it is used during development and in endocrine cell target distinct cell and travel through blood stream like hormones functioning.
The statement which is true about the inheritance of hemophilia is that it is a recessive trait on the X chromosome. Thus, the correct option for this question is C.
<h3>What is Hemophilia?</h3>
Hemophilia may be defined as an inherited bleeding disorder in which the blood does not clot properly. This can lead to spontaneous bleeding as well as bleeding following injuries or surgery.
Hemophilia is significantly caused by the lack of clotting factor VIII or IX in the blood. In most cases, hemophilia is passed down through families (inherited). Most of the time, it is passed to male children. Several women in the family were carriers of the allele for the disorder, only men ended up actually expressing the disorder.
Therefore, the statement which is true about the inheritance of hemophilia is that it is a recessive trait on the X chromosome. Thus, the correct option for this question is C.

Answer:
Q9 is Elliptical and Q10 is sideways i think. Im not sure. Sorry if its not correct.
Explanation:
Mutations can cause instant adaptations, while natural selection is the process by which adaptations occurs over a series of generations. Adaptations are changes or processes of changes by which an organism or species becomes better suited for its environment. A mutation is an alteration of the DNA sequence.
Answer:
My guess would be C
Explanation:
The crust, which is Earths outer solid layer of rock, is around 20km thick if I remembered correctly, and the ocean is nowhere near that, so there would be rock under the ocean.
If you find a better answer, then use it, because I'm not completely sure, but that's my best guess based on the possible answers
