The plasma membrane of axon is called axolemma. The potassium and sodium leak channels leak the sodium and potassium ions inside the cell respectively. The leak channels provide the constant movement of ions across the membrane. Potassium and sodium ions are positively charged, thus entry of positively charged ions inside the cell makes the cell more positively charged than the environment outside the cell. The environment outside the cell becomes more negatively charged. This leads in the negative membrane potential of axolemma.
Answer:
d.The transferred traits were heritable.
Explanation:
Griffith's experiments with S. pneumoniae were significant because they showed that traits could be transferred from one organism to another and these transferred traits are known to be as heritable traits. In another experiment carried out by Hershey and Chase experiment it was confirmed by the results that DNA is actually the hereditary material not the protein.
Amoebas are single-celled organisms, which means that they are composed of just one cell. Each amoeba is a cell capable of performing all living functions by itself. They can reproduce asexually. They are protozoans with no fixed shape. Most have no hard parts and look like blobs of jelly.
Potential gravitational energy is computed with the formula:

Where:
PEgrav = Potential gravitation energy (J)
m = mass (kg)
h = height (m)
g = acceleration due to gravity (9.8m/s^2)
Take note that acceleration due to gravity is a constant.
All you need to do is put in what you know and solve for what you don't know. So your given is the following:
PEgrav = 3,528J
m = 24 kg
g = 9.8 m/s^2
Put that into your formula:




The height of the cliff is 15m.
Sorrowful mood is described a sad feeling, especially when it involves grief or loss. For example- the loss of a thing one loves the most, the loss of a loved family member etc.
So, here in these lines of the poetry, the last line describes the sorrowful mood of the poet.
