The symbol C represents Carbon.
CaCO₃ ⇒ CaO + CO₂
Calcium carbonate is a compound which comprises of elements such as :
<h3>Compound</h3>
This is formed from the combination of two or more elements in a chemical
reaction. In this scenario, the elements are combined in varying proportions
to form the compound.
Carbon is an elements which is denoted with the symbol C which makes it
the appropriate choice.

Answer:
I have found the choices that are written with this question. For ease of understanding and a better way for explaining the answer I have listed them below:
a. difficulty in classifying species
b. difficulty in classifying asexual species
c. difficulty in classifying hybridizing species
<u><em>d. difficulty in classifying fossil species</em></u>
e. difficulty determining when one species changed into another
Explanation:
The evidence already exists that are required to answer these scientific questions. At this point in time scientists can use genetic data to understand the relationship between species. In some instances the data that is acquired is not enough or it is damaged and not well preserved. Here, along with palaeontologist the scientists can use all the evidence they find to better create cladograms and classification charts to date back our common ancestors.
Even with this great scientific tool it is still a challenge to properly identify the speciation to <em>H. sapiens. </em> The continued advancements in science is closing the gap on these set backs and hopefully in time this can be overcome.
In conclusion, the answer here is <em><u>d. </u></em> It is currently a challenge identifying fossil species.
Answer:
The correct answer is C) <em>Acetylcholinesterase.</em>
Explanation:
Neurotransmitter release occurs in the neuron axon. The sending neuron has vesicles filled with neurotransmitters in their interior. When an action potential reaches the nervous terminal or the varicosities, it causes the neurotransmitter release by exocytose forward to the synaptic space. The molecule binds to its receptor in the postsynaptic neuron. This receptor is a protein structure that triggers an answer. As long as the acetylcholine is in the synaptic space, it keeps linking to its receptor and causing a postsynaptic answer. To stop this process, the neurotransmitter must be taken out from the synaptic space. There are two mechanisms by which the neurotransmitter can be eliminated:
- <em>Enzymatic degradation/deactivation</em>: In the synaptic space, there is a specific enzyme called Acetylcholinesterase that can inactivate the neurotransmitter by breaking or degrading it. In this case, the new molecule won’t be able to bind to the neurotransmitter receptor.
- <em>Reuptake</em>: There are receptors located in the presynaptic membrane that can capture de molecule to store it back in new vesicles, for posterior use.
If you want a description of Bryophyte or how it looks like is that:
It is a small green plant that is flowerless and consists of Mosses and Liverworts. It can also be referred as Embrophytes.
Answer:
The tidal force causes Earth—and its water—to bulge out on the side closest to the Moon and the side farthest from the Moon. These bulges of water are high tides. As the Earth rotates, your region of Earth passes through both of these bulges each day. When you're in one of the bulges, you experience a high tide.
