The answer is 22 hydrogen atoms.
This is a simple sugar compound formula <span>Cn(H2O)n</span>
If you have 11 oxygens that means that the second n in the formula will be 11.
Notice that the H (hydrogen) is followed by a 2, that means that the 11 put outside the parenteses will be multiplied by 2.
11 x 2 = 22 hydrogen atoms

Answer:
This lack of fossil data is expected, because the fossil record is incomplete.
Explanation:
Fossilization is a slow, complex and extremely rare process that depends on several favorable conditions for the conservation of traces or materials left by an organism:
1 - Rapid burial of the material;
2 - Presence of rigid parts that are more resistant to degradation;
3 - The type of sediment should be thin and less prone to erosion.
4 - The environment in which the material is located should be low in oxygen to avoid degradation due to oxidation.
5 - The temperature of the place where the material is buried should preferably be cold because the action of decomposing microorganisms in these environments is much lower.
Therefore, it is very common and expected that the fossil record is incomplete.
Hi there!
In the experiment we can identify the variables to determine if the result of the experiment is sound.
Dependent variable - Growth of plants
Independent variable(s) - Medium of watering, being talked to and not talked to
In an experiment you want to have 1 independent variable to determine if that 1 variable is influencing the dependent variable. Because there are two independent variables in this experiment, it is impossible to tell which one caused the plants that were talked to to grow more. As a result, the correct answer would be...
B. Talking to plants may or may not help plants grow faster because the amount of water given was likely different for each group.
The answer top the question given above is letter c. Surface currents.
There are two types of ocean currents, surface current and deep currents.
Surface currents which are caused by winds,move warm water
away from the equator and cool water away from the poles. Deep currents on the other hand are driven by differences in water density.
