The cobalt chloride and lime water test is a test to identify the products of combustion.
Two substances that are indicated by the cobalt chloride and lime water tests are water and carbon dioxide. In this test, the clear lime water turns milky that proves the presence of carbon dioxide. The blue cobalt chloride paper turns pink that proves the presence of water.
No, it is not possible to produce any other substances while burning a candle in this test. When the candle is burning, the substances produced are carbon dioxide and water.

Baroreflex is a reflex triggered when a baroreceptor is stimulated. In the human body, baroreceptors are found in the carotid sinuses and the sinus of the aorta. These receptors are stimulated during changes in blood pressure. Baroreceptors are sensitive to the stretching of blood vessels.
As blood pressure rises, baroreceptors transmit nerve impulses to the vasomotor center of the medulla oblongata, which is then inhibited. This results in vasodilatation of the blood vessels to reduce blood pressure.
Answer/Explanation:
Stationary organisms generally do not move by self locomotion.They could move through the actions of external forces such as moving water but cannot move alone.
Most stationary organisms (also called sessile organisms) have a motile phase in their life cycle. This allows them do disperse across longer distances. This is important for the survival of the species, as it means they can exploit a larger food supply and other resources.
Answer:
In the given case, the most appropriate step to be taken by Brian in order to formulate the hypothesis is to visit other households with cats. In the given case, Brian has to confirm that whether he is allergic to cats or not, and for this, he must go on to find if a similar sneezing reaction is experienced when he is around other cats apart from aunt's cat.
It can be a case that some other environmental elements may have been resulting in the condition. Thus, wearing a mask would not help the cause straightforwardly as it would not confirm that Brian is allergic to cats.
