Answer:
The electrical signal will not be converted into chemical signal.
Explanation:
The synaptic knob is the bulbous enlargement also called synaptic terminal preset at the end of the axon.
The synaptic knob is a living cell and thus contains all the living features but they also contain the vesicles which store the neurotransmitters, therefore, synaptic knob acts as a site which converts the electrical signal into a chemical signal. The released neurotransmitter from the synaptic knob interacts with the post neuron or recipient neuron.
If the mutation develops in the neurons which result in the formation of neurons without synaptic knob therefore the electrical signal will not be converted into a chemical signal and thus signal will stop.

The white board displays helpful info with regards to a QR scanner associated with the day's lesson plan. The shelves on the far end of the classroom holds up relevant books and other objects that will prove educational for the students. Some schedules have been put up too for the ease of the students.
Answer:
The environmental threat posed by the egregious amounts of plastic waste that have accumulated over the years, and that will likely continue to increase unabated.
Answer:
A major change over long periods of time is best described as macroevolution.
Explanation:
Macroevolution would be referring to evolution on a larger scale where populations speciate etc. A, B and C are various forms of speciation and microevolution would be referring to smaller changes in evolutionary patterns e.g. in adaptive or physical traits which may not be deemed 'significant' enough to be considered a speciation event.
Answer:
The correct answers are: B) Catalase works best at human body temperature, C) Normal human body temperature is 98.6°F, which equals 37°C.
Explanation:
Catalase is an enzyme found in our bodies that has the important task of <u>breaking down hydrogen peroxide</u>, a molecule that is very toxic. For catalase to work at its optimus speed, it need the body to have a temperature of 37° celsius -98.6°F-, which is what we normally call <em>human body temperature</em>. If the temperature rises or falls below body temperature, catalase will still work but at a much slower rate, until it stops working completely.
Not all enzymes work best at human body temperature, some enzymes reach their optimus state at higher or lower temperatures; but it is important to remember that enzymes are proteins, and proteins denaturalize when the temperature becomes to high, making them lose their shape and function.
