Answer:
A. The ecosystem can support fewer foxes than grasshoppers.
Explanation:
Since the energy has to transfer from organism to organism, it reduces in amount. Since there are more grasshoppers than foxes, than the ecosystem can support grasshoppers easily.
Answer:
The correct answer is B. exploitation
Explanation:
Exploitation competition occurs when the interaction of two species is indirect when they complete for the same resource like food, place, etc. The use of resources by one individual species reduces the amount of resources for the other species leading to competition.
So over time the more fit species will out complete the less fit species. So here two species of bird feed on the same food but at different times and so they reduce resources for each other which is an example of exploitation competition.
Answer:
3 Neurons are the specialized cells responsible for allowing all the basic body functions to take place correctly as all the necessary communication happens through them. Muscle cells or myocyte cells are specialized in making all movement possible. These cells have a cylindrical shape that allows them to contract.
Explanation:
4 Each cell must be able to perform as a part of a living organism. Cell specialization is required for cells to perform as a part of a whole living thing. Different cells do different jobs.
Answer:
Semi-conservative
Explanation:
Meselson–Stahl experiment proved that DNA replication is a semiconservative process, feeding E. colo bacteria with different types of Nitrogen isotopes (N14 and N15).
Changing the type of radioactive compound in different times of bacteria grow, they could observe that both of the isotopes were present on the bacteria culture.
Basically, if the bacteria present both of them, the DNA was replicated semiconcervely.
Guess what? they show both! (See the image for more information)
One major risk is mutation. Diseases can mutate just has how we have genetic mutations. The bacteria in the cattle may become immune to the drugs over a long period of time, or mutate and become immune. As we try to fight it with more antibiotics, it may become immune to those as well, eventually creating a bacteria immune to most antibiotics, leaving us unable to fight it, especially in poorer areas, due to the fact that if we did create new antibiotics they would be more expensive than your common antibiotic, such as penicillin.<span />
