Hi , a scientific concept is a scientific theory or law that explains why and how a natural event or process occurs.
Answer:
The three main types of lipids are - triglycerides, diglycerides, and steroids.
Explanation:
Lipids are organic compounds that are fatty acids or their derivatives. Lipids are insoluble in water but soluble in organic solvents (alcohol, ether). The three common lipids are triglycerides, diglycerides, and steroids.
An ester derived from glycerol and three fatty acids is a triglyceride. These are the main component of body fat in the vertebrates as well as the vegetable fat.
A Glyceride consisting of 2 fatty acid chains bonded to a glycerol molecule covalently through ester linkages is a diglyceride.
Biologically active organic compounds with four rings arranged in a specific molecular configuration are steroids.
The right option is; d. consumers
All animals are consumers
Consumers are organisms that usually feed on other organisms or organic matter in order to gain energy because of their inability to manufacture their food from inorganic sources. All animals are consumers and they are also known as heterotrophs. There are different types of consumers. They include; primary consumers (herbivores e.g. goats, cows), secondary consumers (carnivores e.g. wolves, crocodile), and tertiary consumers (large carnivores e.g. eagle, lion)
The roots of the plant do not make the food. Thus, the answer to this question is letter B. The roots hold the plant in place and through them the minerals and water from the soil. The roots is also involved in the vegetative reproduction and competitions with other plants.
