Answer: Yes
Even if there is an abundance of fish in the oceans, and that even if the general rule is that big things eat smaller things, it is not true with the <span>orca population (whales). Whales depend on chinook salmon for survival, and truly, the hypothesis that the lack of chinook salmon negatively affecting the orca population is true.</span>
<span>However, for a hypothesis to become lifted to the ranks of a theory once it passes a series of tests. Other scientists may claim its correctness, other may oppose to it. So there is a need to </span><span>differentiate between the hypothesis on checking and competing hypotheses.</span>
Answer:
The correct answer will be option- D.
Explanation:
Neurons are the cells which help in the transmission of the signals to and fro from the CNS and PNS to the body and vice versa. The structure of the neurons is divided into three main parts: the axon, dendrites and the cell body. The dendrites and axons are the extensions of the cell cytoplasm and together constitutes the neurites.
The dendrites are the extensions of the cytoplasm which receives the signals either from the cell surface as well as the from the post-synaptic neurons and further process the signals.
Thus, option- D is the correct answer.

Answer:
Explanation:
A Pure bacterial culture must be grown in sterile tryptophan or peptone broth for 24–48 hours before performing the test. A sterile environment helps to avoid contamination.
When a test is conducted and it shows the presence of a red or red-violet color in the surface alcohol layer it means the result is positive
But when the colour is yellow it indicate negative reaction due to glucose fermentation.
A deviation from two color may also occur when we have an orange color. This colour change is due to the presence of methyl indole
When there is no color change this indicate No decarboxylase which is an enzyme needed for the fermentation reaction.
Color changes are indicator of how successful the reaction was.
