Answer:
In the case of seeing a ball and kicking it can be expressed in the actions of the nervous system as follows:
Part 1. Eyes see the ball and send signals with the help of sensory neurons that carry this message to the spinal cord.
PArt 2. The spinal cord processes the information and sends an "impulse" of kicking the ball that will transfer to motor neurons that transfer it to the brain and then muscles.
Sensory neurons --> spinal cord --> motor neurons --> brain---->leg muscles

Answer: Line A is the enzyme, and Line B is the no enzyme
Explanation:
The reaction rate of a chemical reaction is greatly impacted by the presence of an enzyme. Enzymes are biological catalysts that speed up the chemical reaction by lowering the activation energy required for the reaction to occur. Without an enzyme, the reaction rate may be slow or even non-existent, whereas with an enzyme, the reaction rate can be significantly increased.
In order to compare the reaction rate with and without an enzyme, a graph can be plotted with time on the x-axis and the amount of product formed on the y-axis. The reaction without the enzyme would have a slower rate of product formation and would result in a lower slope on the graph. On the other hand, the reaction with the enzyme would have a sharper rate of product formation and would result in a steeper slope on the graph.
It is important to note that the reaction rate with an enzyme can only be increased up to a certain point, as the enzyme can become saturated with substrate molecules. At this point, the reaction rate will plateau and adding more substrate will not increase the rate of product formation.
Understanding the role of enzymes in chemical reactions is crucial in fields such as biochemistry and pharmacology, as many drugs and therapies work by targeting specific enzymes in the body. By manipulating the activity of enzymes, scientists can alter the rates of chemical reactions and ultimately impact physiological processes.
Answer: The air spaces in the spongy layer of a leaf connect with air through stomata in the epidermis of the leaf.
Explanation:
The cells in the spongy layer of the leaf contain less chloroplast but act as storage for product of photosynthesis like sugars,amino acids and bases.
The air spaces in the spongy layer connect with air through stomata in the epidermis of the leaf. The air spaces in spongy layer allow diffusion of carbondioxide and oxygen and stomata which is a small pores in the epidermis allow carbondioxide and oxygen to enter and leave the leaf.
