Answer;
-Positive charge
Prior to the arrival of a signal from a presynaptic input, the post-synaptic membrane is polar with a greater relative positive charge to the ECF
Explanation;
-Neurons talk to each other across synapses. In somatic neurons, an action potential arrives at the synapse causing synaptic vesicles to fuse with the presynaptic membrane. The pre-synaptic membrane releases acetyl choline via exocytosis into the extracellular of the synaptic cleft.
-The ACh diffuses across the cleft and binds to the ligand-regulated sodium channels. Activated sodium channels allow a rapid diffusion down its electrochemical gradient towards the ICF. The movement of positive charges to the ICT causes the relative charge across the membrane to become positive on the inner surface.
Do you have options to pick from
<span>The option which is not a potential concern associated with the use of biotechnology is the production yields of GM foods, whereas the other options are quite dangerous when you think about them. Genetic ownership means that somebody could steal your genes and use them for cloning, which is another option here. Trainsgenic foods also have to be kept safe, so as to stop someone from messing with them. The production yields of GM foods is not the problem, the problem is whether that food is healthy or not.</span>
Answer: Option B) Nuclei house the DNA, which is the blueprint for proteins. Cell types I, II, and III can synthesize proteins.
Explanation:
All the genetic information that determines the traits expressed in an organism are loaded up within the DNA sequence. Hence, several genes that codes functional proteins are derived from the DNA, making DNA a blueprint for protein synthesis.
Thus, Cell types I, II, and III with DNA can synthesize proteins.
