Answer:
Answered below.
Explanation:
During the absorption of glucose in the small intestinal lumen, the following processes occur.
Sodium ions inside the small intestinal cells are moved into the interstitial fluid and into the blood by the sodium-potassium pump.
The resulting low sodium in the intracellular environment creates a concentration gradient that triggers the transportation of sodium ions from the intestinal lumen into the small intestinal cells or enterocytes, by a mechanism called facilitated diffusion. Facilitated diffusion means diffusion facilitated by a transport protein. This transport protein, called the the sodium-glucose cotransporter, transports sodium alongside with glucose into the cells.
After glucose has been transported into the cell,it is then moved through the basal and lateral membranes into the blood by another transport protein called GLUT2.
Out of the following choices;
<span>a) </span>tail b) DNA c) base plate d) protein coat e) head.
The answer is B. Phosphorus-32 is a radioactive isotope of phosphorus. It is used to label the DNA of the phage because phosphorus is an important element in the structure of DNA and the radioactive phosphorus can be tracked, unlike the naturally-occurring phosphorus. Phosphate groups are critical in the formation of 3’ to 5’ sugar-phosphate backbone bonds between adjacent nucleotides to form DNA.
Answer:
Yes environment plays an important role in human growth, development and health.
Explanation:
As an environment is valuable for all living being so as human need environment to survive .if a person grows in healthy environment that person have positive thinking and can cope with difficult as situation but if the person is grown in unhealthy environment then that person language style all affect people living around that person .as growth and development also is affected by environment and activities performed in that environment
False — life cycles have to do with birth to death progressions, not genetic traits.
