Answer:
The reflex arc follows this sequence of events
1. sensory receptor activation
2. sensory neuron activation
3.information processing
4. motor neuron activation
5. effector response
Explanation:
Reflex arc is the pathway of nerves during a reflex action. An example of a reflex arc is when we accidentally touch a hot object. First, the receptor in the skin detects a stimulus in this case the change in temperature. Second, the sensory neuron transmit the electrical impulses to the Central Nervous System for information processing. Then relay neurons connect sensory neurons to motor neurons. Third, motor neurons sends electrical impulses to an effector wherein the effector produces a response ( muscle contracts to move the hand away from the hot object. This happens in a split of seconds.
Answer:
Professional gardeners often soak seeds in hydrogen peroxide before planting them in order to increase the germination percentage or to reduce germination failure. When the seeds are soaked in hydrogen peroxide, the seed coat becomes soft and enzymes present in the seed becomes active. Due to soaking of seeds, the seed takes less time to germinate. So that's why gardeners uses this method.
Answer:
The answer is animal actions
Explanation:
It said it in the guided notes associated with the lesson.
Answer:
the rats weight loss
Explanation:
<em>The dependent variable would the weight of the rats.</em>
<u>The dependent variable is the variable whose value is dependent on another variable during an experiment. It is the actual variable set out to be measured or tested by researchers. The effect of the manipulation of the independent variable is measured on the dependent variable.</u>
Hence, in an experiment aimed at determining whether a new diet medication will help rats to lose weight, the weight loss by the rats would be the dependent variable.
Arteriosclerosis: It's when your arteries get hard.
Atherosclerosis: It's the medical term for when your arteries are clogged with cholesterol.
