<u>Answer:</u>
<em>Whistling seen as a bad practice by sailors because it challenges the sea is an example of pseudoscience.
</em>
<u>Explanation:</u>
Pseudoscience literally means false science. It claims to be science but it is not scientific at all. It completely fails in a <em>scientific scrutiny </em>and it is not open to evaluation by other experts.
They are just beliefs and practised claimed to be factual even without any proper method used in <em>developing the hypotheses.
</em>
False<em> pseudo scientific claims</em> can be harmful at times. An example is the propaganda against vaccination.
Answer:
3. detection and response to stimuli
Explanation:
According to the given information, the thermoreceptors present in the skin layers of dogs and cats sense the change in the temperature of surroundings. When the temperature is reduced during a cold day, the sensory information about the same is sent to the central nervous system which in turn sends the motor information to the related muscles and glands.
One such response towards the lower temperature conditions is an expansion of their skin coat layers to insulate the underlying tissues from the cold surroundings. The same response (expansion of skin coat) is produced when these animals sense the danger of the presence of large predators around them.
Answer:
Insulin
Explanation:
Insulin signalling promotes lipid storage in adipocytes by both stimulating triacylglycerol synthesis and inhibiting its breakdown.
Insulin’s inhibition of lipolysis aids storage of lipids and also decreases circulating fatty acid level.
The ion which is entering axon terminal A is called Ca²⁺.
The effect which it has is, it causes the release of neurotransmitter from the axon terminal.
Axon terminal is termed as distal termination of telodendria of an axon. Another name for the axon terminal is synaptic boutons. Axon is a long, slender projection which is of a nerve cell.
Their work is to conduct electrical impulses which are referred to as action potential which is a way of neurons of the cell body. Neurons use electrochemical signals and also a neurotransmitter chemical which transmits impulses from one neuron to another.
Axon terminals are being separated from neighboring neurons by a gap known as a synapse. Both the axon terminal and neuron they come from a point which is called the presynaptic neuron.
