Answer:
C. More young children live in Country 1 than in the other countries.
Explanation:
The described graph shows that more young children live in Country 1 than in the other countries. This is clearly stated in the first paragraph: <em>This is the greatest percentage of any 4-year age span in all three countries.</em> This automatically means that options B and D are incorrect.
Option A is the second-best one. However, the fact that there are more young children in Country 1 doesn't necessarily mean that their death rate is lower. It could be, but correlation doesn't equal causation. There are more young children probably because the younger population is more present in that country and more children are born.
This is why option C is the correct one.
Answer : Option B) Density - dependent factor.
Explanation : Typhoid outbreak is dependent of the density as the people of the region are getting the water from the same source so, the density of the area is also an influencing factor in spreading the disease. The bacteria is also getting transmitted from one human to other human too.
Answer: In photosynthesis, the Electron Transport Chain consists of 2 photo systems which use light energy from the sun. The ATP synthase uses the proton gradient established from the ETC to create more energy. ATP is produced from ATP synthase. NADPH is produced from the NADP reductase process.
The saturation of hemoglobin is <u>100% </u>at the arterial PO₂ of 95 mmg and is <u>75% </u>at the venous PO₂ of 40 mmHg
<h3>Saturation of Hemoglobin</h3>
The saturation of hemoglobin at the arterial PO₂ is 100 percent due to the constant supply of oxygen taken in from the environment. while at the venous PO₂ the hemoglobin is 75% due to the limited supply of oxygen.
Hence we can conclude that The saturation of hemoglobin is <u>100% </u>at the arterial PO₂ of 95 mmg and is <u>75% </u>at the venous PO₂ of 40 mmHg.

A claim is an unverified statement or theory which is made about something which may or may not be true.
<h3>Verification of a claim</h3>
For a claim to be validated, i.e, proven to be true (in science), then there needs to be tests and experiments which needs to be carried out to show that the claim is valid.
With this in mind, if for example if there's a claim that jewelweed helps to treat symptoms caused by poison ivy, then there needs to be a controlled experiment to see if this is true or not.
If after a series of experiments and it can be established without any iota of doubt, then the claim is valid and the scientific process will move to the next stage.
Please note that your question is incomplete so I gave you a general overview to give you a better understanding of the concept.
