Answer:
There are three types of lipids in the body, triglycerides, phospholipids and sterols.
Explanation:
Triglycerides are also known as triacylglycerols and compose 95% of fat in the foods we eat. Triglycerides are also the main fats we store in our body. When you pinch an inch around your waist, you are pinching triglycerides.
Phospholipids bring water and fat together and are called emulsifiers. Phospholipids make up cell membranes and lipid carrier molecules.
Sterols are found in tissues of animals and plants. The most well known sterol in our body is cholesterol. Cholesterol makes up bile, hormones and vitamin D.
Both protons and electrons has 21.
Metabolism is the process by which snakes break down food for energy and expel waste.
The majority of digestion takes place in the snake's j-shaped stomach. Digestive enzymes and pancreatic juice which breakdown protein are secreted by the stomach's cells. The food then enters the small intestines after passing through the pyloric valve.
The snake coats its prey in saliva before dragging it into the oesophagus. The food is then crushed and pushed further into the digestive tract, where it is broken down for nutrients, using the muscles of the animal.
Their metabolisms also slow down as they become colder. Therefore, snakes typically have a very low metabolism because they can periodically get their heat from the sun's energy instead of depending on metabolic heat. Since they require less energy to function, they do not require a steady supply of food.

The correct answer is B. A bony skeleton
Explanation:
In biology, Chondrichthyes are mainly marine jawed fishes that have cartilage skeletons rather than bone skeletons and also they have paired fins, this includes animals such as rays and sharks. In terms of origin, it is believed this type of fishes are mainly linked to placoderms that were a type of primitive fish that lived during the Devonian period that had a body skeleton as they were covered by hard structures called plates made of bone. Because of this, it is believed this structures evolved into less rigid ones made of cartilage although both the primitive fish and modern Chondrictyles share features such as the structure of jaws. Therefore, Chondrictyles descended from fishes that had a bony skeleton.
Destruction and replacement of ournative plants by invasive species has several significant consequences. Wildlife that depends on native plants is often unable to adapt and may be forced to leave the area or die out.Invasive aquatic plants can completely fill a water body, driving fish and wildlife from the area.
