I biome is made up of naturally occurring flora and fauna. Fauna is which of the following?
plants |
|
minerals |
|
animals |
|
habitats |
A biome is a large naturally occurring community of flora (plants) and fauna (animals) occupying a major habitat (home or environment).
Bronchioles, alveolus, and capillaries are vital parts of which bodily system?
nervous |
|
respiration |
|
digestion |
|
circulation |
The trachea branches into the left and right bronchi which each lead to a lung where the bronchi subdivide into smaller tubes called bronchioles. Each bronchiole ends in a small sac called an alveolus which allows oxygen from the air to enter the bloodstream via tiny blood vessels called capillaries.
A large naturally occurring community of flora and fauna occupying a major habitat is:
a population |
|
a community |
|
a food chain |
|
a biome |
A biome is a large naturally occurring community of flora (plants) and fauna (animals) occupying a major habitat (home or environment).
Which of the following is the correct order for types of radiation from longest to shortest wavelength?
visible light → ultraviolet light → radio waves |
|
microwaves → radio waves → visible light |
|
infrared waves → microwaves → ultraviolet light |
|
radio waves → visible light → gamma rays |
The electromagnetic spectrum covers all possible wavelengths and frequencies of radiation. From lowest frequency (longest wavelength) to highest frequency (shortest wavelength) radiation: radio waves → microwaves → infrared waves → visible light → ultraviolet light → X-rays → gamma rays.
In which type of compound are electrons shared between atoms?
molecular |
|
covalent |
|
ionic |
|
chemical |
A compound is a substance containing two or more different chemical elements bound together by a chemical bond. In covalent compounds, electrons are shared between atoms. In ionic compounds, one atom borrows an electron from another atom resulting in two ions (electrically charged atoms) of opposite polarities that then become bonded electrostatically.
