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.
<h3><u>Answer and explanation;</u></h3>
<u>Binary Fission. </u>
- <em><u>Binary division is a process of cell division in which an organism replicates itself together with its DNA, then divides into two identical organisms.</u></em>
- <em><u>Binary fusion is a type of asexual reproduction by separation of the body of n organism into two bodies</u></em>. Organism duplicates its genetic material also known as the DNA, and then divides into two parts, with each new organism receiving a copy of DNA.
Answer:
The claim by the researcher is supported because of the known functions of insulin and growth factors. Both hormones have a tendency to respond to the presence of glucose. The growth hormone initiates STAT5 signaling for producing the Igf-1 factor that is important for utilizing glucose. The insulin hormone is well known for utilizing glucose.
Answer:C
Explanation:
The arteries are not a cell bc that is too simple a tissue is also too simple its not a system bc arteries are not a lot of organs working together so its C
Answer:
The seafloor is only 180 million years old due to the process of subduction. The floor of the sea's tends to get colder and denser with the passage of time. At a certain time, the seafloor becomes so dense that it sinks in the upper mantle. The Earth's crust cannot undergo this process and hence has oldest rocks. We can say that the seafloor is less than 180 million years old because it is typically recycled back into the mantle of the Earth.
