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.
<u>Answer:</u> Mutations are the most fundamental way to add new genes to a gene pool.
<u>Explanation:</u>
Mutation refers to the process through which the normal sequence of altered. It may be either acquired or hereditary. It leads to addition of new genes to a gene pool.
The reason for not considering other statements as true are:
1. It is the hereditary mutation that are passed form parent to offspring's and acquired mutation is caused by external factors.
2. Acquired mutation are caused by external factors such as radiation.
3. Germ line mutation are important to evolution because they can be inherited.
The correct answer is body type, cell type, cell structure, nutrition. Organisms are classified into six Kingdoms of life: Archaebacteria, Eubacteria, Protista, Fungi, Plantae, and Animalia. Organisms are placed into these categories based on similar or common characteristics.
