Answer:
The presence of fins in both species represents an adaptation to the same environment (i.e., sea), but in no way does this adaptation means close evolutionary homology between fishes and mammal cetaceans (whales)
Answer:
The results from this experiment conclude that all of the resulting bacteria contain the pUC18 plasmid without the human gene.
The method of genetic engineering might seem very easy but in actual it is a very difficult task and most of the time a person won;t get the expected results. The chances of a vector to actually take up a recombinant DNA are very less. Even after this, the chances of a recombinant plasmid to enter a bacterial cell by transformation are very few.
The energy that can be renewed again and again is known as renewable source of energy. Example : water, sunlight, wind et cetera.
The energy cannot be created again,once destroyed is known as non renewable source of energy.
The energy obtained from coal is non-renewable.
Energy obtained from burning plant waste is renewable
Energy obtained from water spring inside the earth is renewable.
Energy obtained from natural gas is non renewable.
<span>Letter A is the answer. Almost all plant cells have single large central vacuole. These large central vacuoles of the plant cells are filled with water and can take over 80% of its cell volume. This is surrounded by a single membrane called tonoplast. The role of the central vacuole is maintaining the plant cell's pressure.</span>
