Answer:
Chloroplasts are the food producers of the cell.
Answer:
through
space at the speed of light. Sometimes astronomers will use two
telescopes on opposites sides of a planet and combine the image from
each telescope. When combined, the two telescopes act like one giant
telescope and have the ability to reveal important details from space. If
astronomers are detecting electromagnetic waves with a wavelength of
109, what type of wave are they detecting?*
Explanation:
NICE
Answer:
Large areas of the earth with similar climate and ecosystems are called biomes.
Explanation:
Biomes are defined as areas of the planet with common characteristics, such as animal and plant species, as well as climate, which is why it is called a bioclimatic landscape.
When a relationship is established between an ecosystem —with all its biotic and abiotic components— and the climate in a given area, reference is made to a biome. Consequently, a <u>biome represents large areas of land with similar geographical, climatic and biological conditions</u>.
The other options are not correct because:
- <u><em>Communities</em></u><em> are groups of individuals with common characteristics.
</em>
- <u><em>Populations</em></u><em> are individuals of the same species that occupy a certain space in a certain time.
</em>
- <u><em>Organisms</em></u><em> are synonymous with living beings.</em>
Answer:
A. They were part of the control group
Explanation:
In a scientific experiment, the CONTROL GROUP as opposed to the experimental group is the group that does not receive the experimental treatment. This acts as a standard for comparison.
In this question, the EXPERIMENTAL VACCINE is the experimental treatment or independent variable that was added. The five animal test subjects that was injected with this vaccine are called the EXPERIMENTAL GROUP while the other five test subjects that were rather injected with a PLACEBO are called CONTROL GROUPS.
Answer:
False
Explanation:
One of the proof of a good scientific experiment is the ability to reproduce the steps leading to the results obtained from the experiment.
To proof the validity of the claims of an experiment by other scientists:
- Every experiment must be reproduceable by other scientists.
- This will enable the experiment to be rid of any bias.
- For the conclusions of an experiment to be validated by other scientists, such experiment should be tested by others.
- If the results are the same, then the hypothesis can be advanced.
- If not, the experiment is redesigned or discarded.
