Answer:
Population dynamics can be described as the size of a particular population and the environmental and biological factors which influence it.
For human populations, a population which is greater than the resources can be controlled by decreasing the number of births in that population. It can be controlled by people migrating from the place due to less resources available.
For animals, the population can be controlled by increasing the amount of predators for the particular population so that they decline in number. Or shifting of the organisms can be done to places where there are enough resources available.
Answer:
To clearly see specimens under the microscope, and to be able to see two separate objects that are close together.
Explanation:
A microscope is a tool that makes an object look bigger so that the person who is looking at it can see it. It's important to use a microscope because cells are usually too small to see with the naked eye. In addition to magnification, microscopes also have resolution, which is the ability to see two objects that are close together as separate. A microscope needs both magnification and resolution to be able to clearly see specimens under the microscope. When the light microscope bends light at the specimen, it gives the viewer a clear picture of the specimen. A series of lenses do this.
Answer:
gross anatomy, an anatomical region
Explanation:
Anatomy can be grouped into gross anatomy and superficial anatomy. Gross anatomy is the study of structures that are visible to the human eye i.e. without the aid of a microscope. The anatomical regions are those regions in the body that are easily seen by the unaided eye.
In this case, Luna is trying to study the name and locations of the lumbar, or lower back, area of the body. The lumbar is the vertebrae found at the lower back of the body. Hence, it is an easily visible internal structure when dissected, making it's study a form of GROSS ANATOMY.
When the bond between the second and third phosphate group is broken in ATP, ADP is formed and energy is released. This energy can power the cell's functions.
