If a planet exists near a distant star, the star may have a very slight back and forth motion.
D, because if you burn fossil fuel the smoke while burning the fossil fuel is carbon dioxide and we live off fossil fuel and that means we use a lot of fossil fuel.
Answer:
The amount of energy in the first level determines how many animals can be supported on the subsequent levels.
The first level of the energy pyramid usually consists of the producers which are the main source of energy for a food web or a food chain. They determine that how many number of species can be supported by the particular ecosystems at each subsequent levels of the energy pyramid. They are the main source through which energy arises in an ecosystem.
Answer:
One strand of all the isolated DNA double helices would have C-14 labeled thymidine.
Explanation:
DNA replication is a semiconservative process which means that each newly formed DNA double helix contains one parental strand and one newly formed strand.
Since the medium has thymidine labeled with C-14, all the newly formed strands formed during DNA replication would have radio-labeled thymidine.
Therefore, by the end of 20 minutes, one out of two strands on each double helix would have labeled thymidine nucleotides.
Answer:
d. does not have the ability to develop into a new organism, but can give rise to any of the cell types in a body
Explanation:
they are referred to as master cells with the ability to make cells from all three basic body layers, so they can potentially produce any cell or tissue the body needs to repair itself.
