Answer:
aortic arches (earthworms)
Explanation:
Earthworms vessels link together
Answer:
Generally, K+ ions ensures re-polarization of the membrane potential. It always ensures that the neuron returns its resting state, protecting the neurons and ensuring episode of rest before the next action potential.
K+ does this by leaving the axon, making the inner layer more negative. This is resting membrane potential. Because there are many K+ channels for leakages out of the neuronal axons.
Therefore, in this scenario, he neuron will return to its resting membrane potential state which between values -50 to -75mV.
Therefore the value of the potential will be -60mV, or within the range of -50 to -60mV. This is because the neuron is is non- excitable.

Cells at Work (Hataraku Saibou)
Answer:
The Answer is, B, C, And E. I just took it on USATESTPREP.
B) G3P can be used to form the backbone of triglycerides. Glycerol combines with fatty acid tails to form lipids.
C) Two G3P molecules can be combined through anabolic processes to form glucose, a six-carbon sugar required by cells.
E) G3P can be used in to synthesize amino acids, which contain a central carbon, a carboxylic acid group, and a variable R group. These amino acids can then combine to form proteins.
Answer:
mRNA: A-U-G-C-A-U-U-A
Explanation:
Given DNA template: T-A-C-G-C-T-A-A-T
Newly transcribed mRNA: A-U-G-C-A-U-U-A
Transcription is a process that uses DNA template strand to make RNA strands. The process occurs in nucleus. The nucleotide sequence of DNA template is always complimentary to its respective RNA sequence.
Here, thymine of DNA template strand pairs with adenine of newly formed RNA. Adenine of DNA template would pair with uracil of RNA. Guanine of DNA template pairs with cytosine.
