Human hormones testosterone and estrogen are considered lipids. what could be the reason for this? a. they are phospholipids. b. they are fatty acids. c. they are steroids.

C. They are steroids

Explanation:

Steroids are lipid hormones and estradiol, which is also known as estrogen, and testosterone. These are sex hormones that are derived from cholesterol, so they are lipids and they share the same characteristics as well, being both fatt acid chains and are insoluble in water. Estrogen is the female sex hormone, while testosterone is the male sex hormone.

water is a polar molecule. a chemical bond is a force of attraction between atoms or ions. bonds form when atoms share or transfer valence electrons. atoms form chemical bonds to achieve a full outer energy level, which is the most stable arrangement of electrons. so, false

explanation:

in h2o molecule, two water molecules are bonded by a hydrogen bond but the bond between two h - o bonds within a water molecule are covalent. the greater the electronegativity difference, the more ionic the bond is. bonds that are partly ionic are called polar covalent bonds. nonpolar covalent bonds, with equal sharing of the bond electrons, arise when the electronegativities of the two atoms are equal.
