Answer:
a. Blood vessels are constricting causing greater peripheral resistance.
Explanation:
Peripheral vascular resistance means the resistance in the circulatory system that is used to control blood pressure and the flow of blood. When blood vessels constrict, there would be an increase in systemic vascular resistance. When blood vessels dilate, there would be a decrease in systemic vascular resistance.

Explanation:
To decide which days would be okay for her team to conduct the experiment that involves, canopy fogging, here are some information and facts that we should have in mind:
1. Canopy fogging is a technique employed in the collection of insects in the study of forest insects. It basically involves the use of a chemical that would only affect only insects, such as pyrethrine.
2. A sprayer, which may be in the form of a machine is used in spraying this chemical in the form of aerosol with the aid of a blower.
3. Living insects are mostly collected this way for research and studies.
4. Canopy fogging is not usually done when the weather is windy and/or raining. Wind and rain would disrupt the effectiveness of the chemical used in fogging. Wind would blow away the tiny particles of the chemicals being sprayed. Rain may also wash away the particles, and rain might come with storms, hence wind would be present also.
5. Canopy fogging can be done in a sunny and windless weather with no storm.
<em>So therefore, </em><u><em>Monday, Saturday and Sunday</em></u><em> should be ideal days for carrying out canopy fogging since rain and/or wind are absent in these days.

Answer:
Enzymes have specific sites which are known as the active sites. The shape of the active sites is specific for specific kinds of substrates. This allows every enzyme to be specific for its action. Only the specific substrate will be able to fit into the active site and hence, activate the enzyme. The presence of active sites makes the activity of each enzyme specific and hence, every enzyme is able to catalyze a specific kind of reaction.
