Answer:
The correct option is <u>B. Lipids</u>
Explanation:
Lipids can be described as molecules which dissolve in non-polar solvents and cannot dissolve in water. The biological function of a lipid molecule is to store energy as well as to structure the shape of cell membranes. Lipids are also used in a cell for signalling.
Lipids are made up of carbon, hydrogen and oxygen. Some lipids might have phosphorus in them like the phospholipids which make up the cell membrane.
Answer:
Species interactions within ecological webs include four main types of two-way interactions: mutualism, commensalism, competition, and predation (which includes herbivory and parasitism).
Explanation:
The main reason for the difference in the mass extinction occurring today and previously is the pace of the current extinction. The extinction is taking place globally and involves hundreds of species at the same time. In less than 50 years, we have lost numerous species. In contrast to this, previously during the mass extinction, only a few species were lost, and other managed to survive. But, not the status is opposite due to the magnitude of the extinction.
