The answer is the vacuole
Answer:
Monday, Saturday, and Sunday
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:
<u>d. Skeletal muscle</u>
Explanation:
There are two components of efferent nervous system.
- <u>Somatic nervous system</u>
- <u>Autonomic nervous system</u>
<u>SOMATIC NERVOUS SYSTEM:</u>
Somatic nervous is one of the components of efferent/motor nervous system.
It controls <u>voluntary activities</u>. It involves the <u>control of skeletal muscles</u>.
It is composed of <u>the motor neuron and the innervating muscle</u>.
<u>AUTONOMIC NERVOUS SYSTEM:</u>
Autonomic nervous system is the other efferent/motor system of the body. It controls the <u>involuntary activities</u>. It involves the control of <u>cardiac muscle, glands and smooth muscles</u> of the body.
It is composed of<u> 2 neurons; preganglionic and postganglionic neurons.</u>
Autonomic nervous system is further divided into:
- Sympathetic nervous system (it is responsible for flight and fight responses)
- Parasympathetic Nervous system (it is responsible for rest and digestion)
- Enteric division ( controls Gastrointestinal system)
<u>QUESTION:</u>
<u>d. skeletal muscle</u>
This is the correct answer choice as skeletal muscles are not controlled by autonomic nervous system. They are controlled by somatic nervous system and are under voluntary control.
Over dependence on a few staple foods increase the risk of famine because THE FEWER THE STAPLE CROPS THE GREATER THE DANGER TO THE FOOD SUPPLY POSED BY THE CROP FAILURE.
A staple food is a food that is consumed regularly by a community. For example, potato, pulses, rice, wheat, etc.
