Narrow.
For a wide ring, it indicates a longer/faster growing season. Narrower ring means there is less growth, which is likely caused by poor growing conditions.
<span>Well the graph of this equation is a straight line. The
line crosses the y-axis at b. The point where the line crosses the
y-axis is called the y-intercept.</span>
I think its called <span>Encephalitis. I could be wrong

Answer:
2. presence of plasma membrane 3. lack of a nuclear envelope
Explanation:
Both archaeans and bacteria are prokaryotes. The prokaryotic organisms lack the well-defined nucleus and membrane-bound organelles. These organisms have their genetic material present in the cytoplasm itself.
Both archaeans and bacteria have a plasma membrane around their cells. The presence of plasma membrane around cytoplasm is exhibited by all the living beings including all the prokaryotes. Plasma membrane in archaeans and bacteria has the same basic structure. It has two layers of phospholipids in which proteins are embedded.
Answer:
Change in DNA leads to change in the structure of the cell.
Explanation:
Mutation in the 17th nitrogen base of DNA leads to the formation of sickle cell hemoglobin protein instead of normal hemoglobin protein because mutation is the sudden change that occur in the genes of a cell which change the genetic makeup of the cell. So when change occur in the DNA, a sickle cell is formed instead of normal hemoglobin. Normal hemoglobin only formed when the no change occur in the nitrogen base of DNA.
