Answer:
Lipid insoluble hormones/Peptide hormones
Explanation:
Hormones produce their effect by binding to speific receptor. These receptors may be intracellular or membranal.
Membrane receptors;
The lipid insoluble hormones cannot cross the plasma membrane thus their receptors are found on plasma membrane. These are usually peptide hormones.
Examples; Insulin.
Intracellular receptors;
The lipid soluble hormones can cross the plasma membrane thus their receptors are found in cytoplasm. These are usually steroidal hormones.
Example; Testosterone.
Answer:
Species are adapted to their environments. By understanding the interactions within an ecosystem, scientists can develop an understand of how populations evolve (develop gradually) in response to their environment.
Answer:
Function of each male reproductive system-
They produce, maintain and transport sperm and semen . They discharge sperm into the female reproductive tract. They produce and secrete male sex hormones.
Function of each female reproductive system-
The ovaries produce the egg cells, called the ova or oocytes. The oocytes are then transported to the fallopian tube where fertilization by a sperm may occur.
