Answer:
The correct answer is methane . Nature constitutes most of the substances made up of organic compounds. These compounds have carbon atoms attached with hydrogen atoms with a chemical bond (very few compounds may not have this bond).
I think b. Proteins are polymers of amino acids is the correct answer
Answer:
A Scientific Hypothesis Must Be Testable
For a hypothesis to be testable means that it is possible to make observations that agree or disagree with it. If a hypothesis cannot be tested by making observations, it is not scientific.19-Feb-2021
Explanation:
This question is incomplete because the options are not given; here is the complete question:
Which one of the following processes does not occur to excess neurotransmitters in the synapse?
A. Break down or digested into inactive fragments.
B. Collection by scavenger vesicles left over from the neurotransmitter release.
C. Drifting away from the synapse via diffusion.
D. Reuptake within the pre-synaptic neuron.
The answer to this question is B. Collection by scavenger vesicles left over from the neurotransmitter release.
Explanation:
The word synapse refers to the neurological structure that allows the transmission of signals or information between neurons. This process occurs through neurotransmitters, which are the molecules or substances with the messages.
Moreover, in this process, there can be in some cases excess. In this situation, the body reacts to this excess by degrading or breaking down the extra neurotransmitters, eliminating it through diffusion, or even reabsorbing it (reuptake). In this context, all are processes that occur due to excess neurotransmitters except collection by scavenger vesicles because in most cases neurotransmitters are simply absorbed or eliminated but there are not specialized scavenger vesicles that collect them.
