The ester bonds in lipids are found where the fatty acids of the lipid join to the glycerol back bone of the lipid.
Lipids are made from two kind of molecules namely Glycerol and Fatty acids. A glycerol molecule is made up of three carbon atoms with an alcohol group attached to each of the carbon atoms and hydrogen atoms occupying the remaining positions.
A fatty acids consist of an acid group at the end of the molecule and a hydrocarbon chain.
In a process called esterification, the acid group of the fatty acid joins to the alcohol group of the glycerol molecule and water is released resulting in the formation of a linkage called an ester bond.

Answer
(From top left to the bottom) Neisseria gonorrhoeae, Herpes Simplex virus, Human papillomavirus (HPV)
(From top right to the bottom) Theponema pallidum, Chlamydia trachomalis, Candida albicans
Explanation:
Neisseria gonorrhoeae: infected individuals may experience pain when urinating or during sexual intercourse. It may be accompanied by unusual discharge (white, creamy or green) from the vagina or penis
.
Herpes Simplex virus: causes painful sores around the lips and genitals. These sores are contagious
.
Human papillomavirus (HPV): a viral STI, it appears as warts on the male and female genitals when a person is infected. These look like a cluster of pimples
Theponema pallidum: also known as syphilis, it is characterized by painless sores around the mouth or genitals. The sores may later develop into rashes.
Chlamydia trachomalis: may not have any symptoms but if there are any, they include discharge from the vagina or penis
.
Candida albicans: is a fungal infection that produces vaginal discharge that looks like cottage cheese

Answer: Energy transfer takes place when energy moves from one place to another. Energy can move from one object to another, like when the energy from your moving foot is transferred to a soccer ball, or energy can change from one form to another. ... Three more ways energy can be transferred are through light, sound, and heat.
Heredity increases diversity among organisms by nonrandom mating, which is the preference of the organism to mate with another based on specific characteristics. Nonrandom mating has two forms. Inbreeding is the first form where organisms with the same genotypes will mate with each other resulting in minimal genetic diversity. Outbreeding is the second form where organisms of different genotypes will mate with each other resulting in an increase in genetic diversity. The variation in the heredity of an organism allows it to be more flexible and can also guarantee better survival rate of the population under the given environmental conditions.
