Answer:
A. Some were already resistant and were the survivors that could reproduce
Explanation:
Both resistant and susceptible insects will be exposed to DDT, but according to the evolution theory, it is expected that those insects that are resistant to the insecticide will be selected by natural selection. In consequence, the resistant individuals will survive to reproduce in the next generation.
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.
Answer: 5. glycolysis, the tricarboxylic acid cycle, and oxidative phosphorylation
6. If oxygen is not present, some organisms can undergo fermentation to continually produce ATP. Glycolysis, which is the first step in all types of cellular respiration is anaerobic and does not require oxygen.
7. Glycolysis is the process in which one glucose molecule is broken down to form two molecules of pyruvic acid
