The following is correctly matched with its tissue system is -
4) stele/vascular tissue system
Stele is the the central core/cylinder of the stem and root of a vascular plant, consisting of the xylem and phloem and other supporting tissues. Vascular plants include clubmosses, horsetails, ferns, gymnosperms etc.
Answer:
Neurotransmitters
Explanation:
Neurotransmitters are the chemicals that are released from the axon terminals of the pre-synaptic neurons of the synapse. These chemicals have receptors at the surface of the dendrites of postsynaptic neurons of the synapse. Binding of neurotransmitters to their receptors brings about the excitatory or inhibitory effect on the postsynaptic neuron. Accordingly, the action potential is fired. In this way, electrical signals are passed from one neuron to the next at the synapse. Acetylcholine is an example of neurotransmitters.
Answer:
The answers are:
- Type 2 (fast twitch) muscle fibers - type A: b. muscle fibers that help with a long sprint or carry a heavy object a short distance
- muscular strength: d. the muscle's capacity to exert force against resistance
- Type 1 (slow twitch) muscle fibers: a. muscle fibers responsible for endurance
- Muscle endurance: c. refers to the ability to perform a specific muscular action for a prolonged amount of time.
- Type 2 (fast twitch) muscle fibers - type B: e. muscle fibers used in short explosive movements such as jumping or lifting a very heavy weight one or two times.
Explanation:
Types of Skeletal Muscles:
Skeletal muscle are divided into two types:
- Slow Twitch (Type 1)
- Fast Twitch (Type 2)
- Slow twitch muscles are the first ones to contract at times of exercise of strenuous physical activity. A compared to fast twitch muscle fibers, they contract slowly but can sustain contraction for a long time.
- Fast twitch muscle fibers are divided into two subtypes: Type 2A and Type 2B.
- Type 2A muscle fibers produce a high amount of force but they fatigue rapidly.
- Type 2B muscle fibers, fire last, produce the most amount of force but wear out very rapidly.
Muscle Characteristics:
- Muscle endurance is the muscle's ability to contract with force against a resistance for a prolonged time period.
- Muscle strength is a measure of the amount of force a muscle can produce against resistance.
The answer is: 23
You get a total of 46 chromosomes and half come from each parent.
<u>Answer:</u>
A solution that can help to reduce noise pollution caused by things such as pile-driving is air-bubble curtain.
<u>Explanation:</u>
- The noise pollution caused by things such as pile-driven into the soil is very high.
- There are many solutions to reduce this noise pollution, air-bubble curtain is one of the useful and simplest solution to reduce noise pollution.
- This solution is based on dynamic sub-structuring technique and modal decomposition method.
- The major drawback of this solution is sound absorption becomes critical, when this method is employed in smaller piles it is because of the radiated acoustic energy is concentrated at higher frequencies than the resonance frequency of the air bubble.
