With regard to Neural Permeability, the relationships between the two items listed in each care is as follows:
- A. Resting neuron's permeability to K⁺
- B. Resting neuron's permeability to Na⁺ (Option C)
- A. Neuron's permeability to Na⁺ during the rising phase of an action potential
- B. Neuron's permeability to K⁺ during the rising phase of an action potential (Option F)
- A. Resting neuron's permeability to Na⁺
- B. Neuron's permeability to Na⁺ during the rising phase of an action potential (Option B)
- A. Resting neuron's permeability to K⁺
- B. Neuron's permeability to K⁺ during the falling phase of an action potential (Option A)
- A. Neuron's permeability to Na⁺ during the falling phase of an action potential
- B. Neuron's permeability to K⁺ during the falling phase of an action potential (Option D)
It is to be noted that the grading is as follows:
A) is for when B is greater than A
B) is for when B is greater than A
C) is for when A is greater than B
D) is for when B is greater than A
E) is for when A and B are equal
F) A is greater than B
<h3>What is Neural permeability?</h3>
This (in simple terms) refers to the degree to with neurons allow the transmission of solutes and solvents in and out of them.

Answer:
i believe mitochondria
Explanation:
I can't see it very well because it's blurry but if it has back and forth squiggles in the middle then it is the mitochondria plus the others are labeled with other stuff
When a hairpin loop forms in the nascent mRNA: The hairpin will destabilize the interaction and possibly lead to transcriptional termination.
Transcription in prokaryotes like E. coli is terminated either by a rho-dependent process or a rho-independent process. Intrinsic termination is controlled by the specific sequences of RNA .
When the termination process starts, the transcribed mRNA forms a stable secondary structural hairpin loop, also known as a stem-loop. Several uracil nucleotides follow this RNA hairpin. The uracil and adenine connections are exceedingly weak. NusA, a protein attached to RNA polymerase, attaches to the stem-loop structure so firmly that it momentarily stalls the polymerase.
The polymerase is pausing at the same time that the poly-uracil sequence is being transcribed. The RNA-DNA duplex can unwind and separate from the RNA polymerase because the weak adenine-uracil interactions reduce the energy of destabilization for the RNA-DNA duplex. Overall, transcription is terminated by the modified RNA structure.

Answer:
Desmosomes
Explanation:
The plates holding cells together in tissues are called desmosomes. Desmosomes are the tissue basement. They hold the cells together. So the tissues retain in a definite shape. These are the intermediate filaments and make a net-like structure. These are made up of keratins. It is a structural protein found exclusively in nails and hairs. The desmosomes are 3 types- spot desmosomes, belt desmosomes, and hemidesmosomes. Desmosomes are the connection between 2 cells.
