How can using a dam as a source of freshwater also harm wildlife?
A. Dams help control floodwaters.
B. Dams provide drinking water.
C. Dams displace existing habitats.
Ο Ο
D. Dams provide water recreation.
Answer:
c
Explanation:
because its the only one that would be hurting wild life.
Using a dam as a source of freshwater can harm wildlife by displacing existing habitats. Therefore, option (C) is correct.
What are the negative impacts of dams?Dams often require the creation of reservoirs, which can submerge large areas of land and alter the natural flow of rivers and streams. This can lead to the loss of important habitats for fish, mammals, and other wildlife that rely on rivers and streams for food, shelter, and reproduction.
In addition, changes in water temperature, dissolved oxygen levels, and water flow can negatively impact aquatic ecosystems downstream from the dam.
These impacts can be mitigated through careful planning and management, such as the creation of fish ladders and other structures to help fish navigate past the dam, and the release of water at appropriate times to mimic natural flow patterns.

Answer:
Lipids perform three primary biological functions within the body: they serve as structural components of cell membranes, function as energy storehouses, and function as important signaling molecules. The three main types of lipids are triacylglycerols (also called triglycerides), phospholipids, and sterols.
Explanation:
The statement that describes the major role of lipids within a cell is they are the main structural components of membranes. The correct option is D.
What are lipids?Lipids have three main biological activities in the body: they are essential signaling molecules, structural elements of cell membranes, and energy storage facilities.
Triacylglycerols (commonly known as triglycerides), phospholipids, and sterols are the three primary categories of lipids. Fats are subtypes of lipids that are typically composed of glycerol and fatty acid chains.
One sort of lipid, which includes fats, is a group of molecules that don't mix well with water. Hydrophobic, nonpolar, and primarily composed of hydrocarbon chains, lipids have a tendency to be.
