Answer:
After 6000 years, approximately 500 atoms of carbon-14 will be left in the femur bone of an animal which had 1000 atoms of carbon-14 when the animal died.
Explanation:
The half-life of a radioactive isotope of an element is the time taken for half the atoms present in a given amount of the element to undergo decay or disintegration. For example, the half-life of carbon-14 isotope is 5730 years. This means that, if there are 100 atoms of carbon-14 present in a given sample of a material, in the next 5730 years, approximately, 50 atoms of carbon-14 will be left in the material.
Since the half-life of radioactive isotopes are constant, these radioactive isotopes are used in the determining the ages of ancient life-forms as well as rocks.
In the given example, after 6000 years, approximately 500 atoms of carbon-14 will be left in the femur bone of an animal which had 1000 atoms of carbon-14 when the animal died.
Answer:
''Watching television adversely impacted the quality of sleep''.
Explanation:
''Watching television adversely impacted the quality of sleep'' is the best hypothesis for her study. Watching television right before bed, can negatively impact your sleep quality. Late-night watching television disrupts your internal clock that adversely affected sleep quality of an individual. The above hypothesis is used by the Rachel to investigate the impact of watching television before sleeping on the sleep quality.
According to my old biology book 2 terms include snow forest and Tagia
1. A caelifera, or more commonly known as the grasshopper belongs in the animal kingdom. Grasshoppers are a leafy green and can be found in a variety of habitats. They can be found in lowland tropical forests or grasslands. Higher classification for the grasshopper would be Orthoptera. Grasshoppers are jumping insects that belong to the arthropod phylum.
Strong, long hind legs that help them jump. This adaptation helps them get away from harm and jump higher.
3. I said some in the first paragraph.
4. Important in grassland ecosystems and play a role in the nutrient cycling.
5. I don’t think there really is anything else.
