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.
It's letter A - Obligate anaerobe.
<em>Obligate anaerobes</em> are microorganisms killed by normal atmospheric concentrations of oxygen. A <em>facultative anaerobe</em> prefers to produce energy in the presence of oxygen but can survive without it. <span>A <em>photoautotroph </em>is an organism that converts light energy into chemical energy. </span><span>Prokaryotes may perform </span>aerobic<span> (oxygen-requiring) or </span>anaerobic<span> (non-oxygen-based) metabolism and some can switch between these modes. Since we're talking about an environment without oxygen and dies when exposed to oxygen, the preferable answer is A.</span>
Answer:
2.compare a layer at one location to layers at other locations
Explanation:
Comparing rock layers in distant places can be a challenge for geologists since these layers may have different environmental factors that caused different transformations in them.
Therefore, when it is necessary to establish a comparison between layers of rocks in different ligands, geologists must establish steps to make an efficient comparison and have results consistent with reality. To do this, they must first compare a layer in one location with layers in other locations, assign relative age to a layer in one location, and identify index fossils in one or more layers in one location.
A series of steps designed to solve problems and answer questions is "a scientific method".
