Answer:
During daylight hours, plants take in carbon dioxide and release oxygen through photosynthesis, and at night only about half that carbon is then released through respiration. However, plants still remain a net carbon sink, meaning they absorb more than they emit.
B. Nervous and muscular

Answer:
The neuron will not fire an action potential.
Explanation:
The missing magnitudes of the synaptic potentials when they reach the postsynaptic cell's axon hillock are:
A. excitatory +7
B. excitatory +10
C. inhibitory -3
D. excitatory +2
E. inhibitory -4
To fire the action potential, the summation of excitatory postsynaptic potentials (EPSP) and inhibitory postsynaptic potentials (IPSP) must reach the action potential threshold, which in this case is 15mV more positive than the resting potential.
The EPSP are: +7 +10 +2= +19
The IPSP are: -3 - 4= -7
EPSP + IPSP=
+19 -7 = +12 mV
The neuron will not fire an action potential since the integration of EPSP and IPSP is below 15mv.
Answer:
The events of protein synthesis are simple- First of all, protein synthesis is the process for which cells make proteins. Protein synthesis occurs in only two stages, transcription and translation.
Transcription-
Transcription is the transfer of genetic instructions in DNA and mRNA in the nucleus. It includes three steps: initiation, elongation, and termination.
Translation-
Translation occurs at the ribosome, which consists of rRNA and proteins. During translation, the genetic code in mRNA is read and is used to make protein.
Explanation:
The two processes (transcription and translation ) are pretty much summed up by the 'central dogma of molecular biology' which goes- DNA → RNA → Protein.
