In this virtual lab, grow two species of paremecium in test tubes and record data on their population growth. Experiment shows that when grown together, one species will die, illustrating the competitive exclusion principle.
Answer:
The answer should be solid
Answer:
Explanation:
The musculoskeletal system provides a framework to the body. It provides the support and maintains the stability in the body. The musculoskeletal system is composed of bones, muscles, cartilage, joints, tendons and ligaments and other kind of connective tissues that support and binds the tissues and organs together.
A strong musculoskeletal system includes three long term health benefits:
1. Reduce the risk of injury: The strong bones and muscles will prevent any internal injuries as they make up a strong framework against external force and internal muscular stress.
2. Decrease the risk of osteoporosis: The osteoporosis is condition in which pores develop on the bones as a result of which the bone becomes brittle and fragile. If the skeletal system is strong then risk of osteoporosis will also decrease.
3. Improve posture: A strong musculoskeletal will keep the vertebral column upright not in bended state.
Answer:
The reason for qualifying 'in vacuum' is because EM waves of different frequencies often propagate at different speeds through material.
Explanation:
Electromagnetic waves include visible light, radio waves, X-rays, and so on. What distinguishes these different bands of light is their frequency (or wavelength). But what they all have in common is that they travel at the same speed in vacuum.
The reason for qualifying 'in vacuum' is because EM waves of different frequencies often propagate at different speeds through material.
The speed of a wave c, its wavelength λ and frequency f are all related according to c=λf. So if c is the same for all EM waves, then if you (say) double the frequency of a wave, its wavelength will halve.
