Answer:
<u>3. Hot spots , 4. S shaped mid oceanic ridge, pacific ocean</u>.
Explanation:
- The Hawaiian islands are located on the hotspots that are formed by the collision of two strong plates and the presence of volcanoes and high magnitude earthquakes as the pacific plate is continuously moving on the western side as its subducting under the North American plate and hence shrinking in size.
- The s-shaped Atlantic ocean has mid atlantic ridge and as this ocean spreads the lava is up welding across the ocean floor and hence the opening of the atlantic plate is seen.
First they don't use oxygen, plants use the CO2 in the air and release oxygen out into the air after the plant used up the CO2
Answer:
22 cells
Explanation:
The concentration of numbers of cells = 6.74 x 10⁶ cells/ml
Dilution stages includes = 1:100 ; 1:100 & 1:3
The consecutive dilution stages can be calculated as:
= (6.74 x 10⁶) × (1/100)(1/100)(1/3)
= 222.42 cells/ml
= 2.22 × 10² cells/ml
So after addition 0.1 ml of the final dilution to a spread plate, the number of CFUs ( Colony forming units) we expect to count will be:
= (2.22 × 10² cells/ml)(0.1 ml)
= 22.2 cells
≅ 22 cells.
1 - <u>B. Water level and salinity.</u>
2 - <u>B. Oceanic & neritic.</u>
I hope this helps!
