Autotrophs can produce their own food
Answer:
thigh
Explanation:
The muscles that act on the knee joints majorly include the hamstring muscles (semimembranosus, biceps femoris, and semitendinosis) and the quadriceps muscles (vastus lateralis, vastus intermedius, vastus medialis, and rectus femoris).
The quadriceps muscles and the hamstring muscles are the major muscles that make up most of the mass of the thigh. The quadriceps are located at the front of the thigh, while the hamstring muscles are located at the back of the thigh.
B. False

Answer:
Nylon is a strong synthetic fibre, which resists abrasion. Nylon doesn’t shrink or stretch through washing, but it is degraded by ultraviolet light.
Explanation:
Nylon is made when the appropriate monomers (the chemical building blocks which make up polymers) are combined to form a long chain via a condensation polymerisation reaction. The monomers for nylon 6-6 are adipic acid and hexamethylene diamine. The two molecules are combined to create the polymer and water (H2O) is produced as a by-product. The water is removed from the production process as its continued presence stops the creation of more polymer. The polymer chain can be made up of over 20,000 monomer units, connected together via an amide group, which contains a nitrogen atom. The nylon molecules are very flexible with only weak forces, such as hydrogen bonds, between the polymer chains, which tend to tangle randomly. The polymer has to be warmed and drawn out to form strong fibres
