Answer:
Three types of muscles are the cardiac muscles, smooth muscles, and the skeletal.
an example of a cardiac muscle muscles that contract the heart to pump blood. this heart muscle is a striped muscle in the walls of the heart. it is involuntary meaning a person cannot control it consciously.
an example of a smooth muscle is muscle tissue which is used by various systems to apply pressure to vessels and organs. this muscle is also involuntary and are usually in sheets or layers. your brain and body tell these muscles what to do without you even thinking about it.
an example of skeletal muscle are your biceps, deltoids, or even pectoralis. this muscle is called striated, meaning long or streak like, because the light and dark parts of the muscle fibers make them look striped(striated). these muscles are voluntary, which means they can control what you do.
Answer:
1.)Carbohydrates
2.) Lipids
3.)Proteins
4.)Nucleic acids
Explanation:
1. Carbohydrates
The major carbohydrates found in cell walls are cellulose, hemicellulose and pectin. The cellulose microfibrils are bonded through hemicellulosic tethers to give the cellulose-hemicellulose network, that is found in the pectin matrix.
2. Lipids
Cell membrane are majorly made up of phospholipids, glycolipids, proteins, and cholesterol. The lipid found mostly though our the membrane are the phospholipids.
3. Enzymes/proteins
Enzymes are biological molecules that are protein in nature and accelerate the rate of the chemical reactions that occurs within cells.
4. Nucleic Acid
Nucleic acids aid major activities in the cell by serving as the repository of the genetic materials needed for the transfer of inherited characteristics from parents to offspring and from an individual cell to another cell
Cyanide, raw sewage, petroleum from shipping accidents, and detergents are all examples of Water pollution.
Water pollution is the contamination of water bodies by substances like Cyanide, raw sewage, petroleum from shipping accidents, and detergents This makes water unfit for drinking, cooking, cleaning, and other purposes. It may provide an environment suitable for growth of bacteria, algae bloom and other parasites which even destroys the life of animals residing in the water body like fishes.
All other forms of pollution eventually make their way to water and disturb the pH of water. Biochemical Oxygen demand (BOD) is the attribute which measures the pollution in water body at surface level.
Hence,Cyanide, raw sewage, petroleum from shipping accidents, and detergents are all examples of Water pollution.
