I did some research and found that the average human requires 550 L of
oxygen per day which means that :
(550 L O2 / day) x (1 day / 24 hours) = 22.9166667 L O2 / hour or
22916.67 mL O2 / hour
1 mL = 1 cm^3
22916.67 mL O2 / hour = 22916.67 cm^3 O2 / hour
Now convert that volume from cm^3 to nm^3
22916.67 cm^3 O2 / hour = 2.29167x10^25 nm^3 O2 / hour
So for 1 hour’s worth of O2, we need a volume of 2.29167x10^25 nm^3
Plants fertilized once per week with Super Plant Food Formula have been shown in testing to produce twice as much fruit as plants that are not.
Explanation:
A scientific claim out of the options is that plants fertilized once per week with Super Plant Food Formula have been shown in testing to produce twice as much fruit as plants that are not.
A scientific claim is usually drawn from the result of an experiment that follows the detailed scientific steps.
- In the last statement we see that word "testing ".
- This suggests that an experiment must have been conducted before the claim was made.
- To test a claim, a hypothesis is usually drawn out.
- From the hypothesis we can test an observation and answer questions using the data obtained in the experiment.
- Before the assertion was made, experiments have been conducted.
- The other options are claims that have not been tested.

People with HIV are unable to fight off these rare diseases because they have a weakened immune system.

maintaining structure
f. obtaining
energy
These three
traits definitely standout as a challenge for every living creature in the ecosystem.
In Darwin’s Natural Selection Survival of the fittest: being fit is one
category in order to survive the wild, in other words, being flexible. Reproduction
is battle royale in both humans and animals, even for plants too. Why? Because
the ecosystem changes, the weather changes, the food chain is a combat to chase.
Some can’t even reproduce due to hereditary or physical causes. Energy is as
important as living. If plants can make their own food how about the carnivores
and the omnivores. Food is a challenge. Structure is sustaining the capacity
and ability to hunt and survive. Important and a by-product of obtaining
energy.
