Biology
1 answer:
iren [92.7K]3 years ago
7 0

Answer:

Reflex action is the sudden uncontrolled reaction towards a certain stimuli eg response to hot iron

Reflex arc is the path taken by reflex action to a certain stimuli

Diagram depends to

Receptor(eg skin), receptor nerve(sensory neurone),centre reflex arc(spinal cord most of reflex action) they met relay neurone, motor neurone and ends at reflexor (eg muscle)

The two graphs shown here represents a reaction that proceeds without an enzyme (left) and without an enzyme (right). According
nignag [31]

The  role of enzymes in a chemical reaction is to : Lower the activation energy while increasing the rate of reaction

The graph shown on the left is an uncatalyzed chemical reaction while the graph on the right is a catalyzed chemical reaction.

Catalyzed chemical reactions have lower activation energy and a faster rate of reaction while uncatalyzed chemical reaction has a higher activation energy and a slower reaction rate. because catalyst increases the rate of a chemical reaction by lowering its activation energy.

Hence we can conclude that The  role of enzymes in a chemical reaction is to : Lower the activation energy while increasing the rate of reaction

kondor19780726 [428]

Answer:

b. water molecules are strongly cohesive

Explanation:

Water is highly cohesive and clumps together into drops because of its cohesive properties. Water molecules attracting each other result in surface tension, which causes raindrops to form round beads as they fall on a surface.

Hope this helps!
