Answer:
While <u>water soluble</u> hormones can travel freely in the blood, <u>lipid soluble </u>hormones require a carrier protein because they are not soluble in the aqueous plasma
Explanation:
The water-soluble hormones such as insulin are dissolved in the blood and are carried along with the blood to their target cells.
However, lipid-soluble hormones such as steroid hormones (cortisol) and thyroxine are hydrophobic in nature. These hormones are not dissolved in water-based blood plasma. So, these lipid-soluble hormones are carried through the carrier proteins.
Viruses is the answer to this
Carbohydrates provide structural support, in the form of cellulose in cell walls, for plants in addition to providing energy for the organism
Proteins are essential for muscle tissue's growth and development as well as, in the form of hormones and hormonal regulation, maintaining an organism's homeostasis.
Lipids make up the bilayer of cell membranes, and also aid hormonal signaling.
Nucleic acids store genetic information, and allow for ribosomal protein synthesis.
They are the same in that most of the reproductive organs of both sexes develop from similar embryonic tissue, meaning they are homologous. Both systems have gonads (male have testes and female have ovaries) that produce gametes (testes produce sperm and ovaries produce egg or ovum) and sex organs.
