<h2>The correct option is (A) and (B)
</h2>
Explanation:
- Lipids are fundamentally and practically various groups of hydrocarbons. Hydrocarbons are the substance chemical in nature and comprise of carbon and hydrogen atoms. The carbon-carbon and carbon-hydrogen bonds are nonpolar, which implies that the electrons between the molecules are shared similarly. The individual nonpolar bonds grant a general nonpolar characteristics to the hydrocarbon compound.
- The naturally significant classes of lipids are fats, phospholipids, and steroids.
- Carbohydrates are one of three essential macronutrients expected to support life (the other two are proteins and fats). They are found in a wide scope of nourishments that bring an assortment of other significant supplements to the eating routine, for example, nutrients and minerals, phytochemicals, cell reinforcements, and dietary fiber. Organic products, vegetables, grain nourishments, and numerous dairy items normally contain starches in different amounts, including sugars, which are a sort of starch that can add taste advance to a nutritious eating routine.
Answer:
the thin filaments are pulled away from one another, thereby reducing their ability to interact with myosin
Explanation:
The myofibril is the basic unit of a muscle cell. Each myofibril is composed of contractile units known as sarcomeres which may contain two different types of myofilaments: thick myofilaments and thin myofilaments. The thick filaments are known to have a constant length, and they consist especially of myosin proteins. These filaments (thick) do not extend to the ends. On the other hand, the thin filaments extend in from each end, and they are mainly composed of actin proteins that serve as tracks for the movement of myosin proteins.
A microorganism (or microbe) is any microscopic living organism or virus, that is too small to see with the unaided human eye without magnification. Microorganisms are very diverse. They can be single-celled or multicellular and include bacteria, archaea, viruses and most protozoa, as well as some fungi, algae, and animals, such as rotifers and copepods. Many macroscopic animals and plants have microscopic juvenile stages. Some microbiologists also classify biologically active entities such as viruses and viroids as microorganisms, but others consider these as non-living.
