Answer:
if i lived in the 1800s I think would have more free time because i wouldn't be on electronics all the time. I might not have an education because times were hard then and many kids had to work in factories like their parents to support the family. I could get sicker easier because there weren't many health codes back then and lining conditions weren't teh best
Answer:
Only options A (first one) reflects the instances with valid experiment or conclusion.
Quality of any experiment depends upon two things reliability and validity. Reliability is measure of regeneration of results every time an experiment is performed under specific conditions.
Validity is measure of accuracy of results of an experiment. It can be check by two ways: internal validity (checks the design of the experiment) and external validity (checks if the conclusion is the real explanation of the phenomenon).
Now, in marine biologist experiment, he concluded the results only after one breeding season. This makes his results unreliable as it might have happened by chance.
Similarly, in cola experiment the taste was only checked by one candidate i.e. Karl. He might have problem in his taste buds. In addition, the temperature of cola can also affects its taste which is not taken care of in the experiment. Hence, it is not the valid experiment.
Similarly. Jeanette could use more plants for her experiment and Robert just followed only one instruction. He didn't perform any experiment.

Nitrogen is converted from atmospheric nitrogen (N2) into usable forms, such as NO2-, in a process known as fixation. ... The nitrogen is passed through the food chain by animals that consume the plants, and then released into the soil by decomposer bacteria when they die.
The first question can be answered by science due to its logical features.
<h3>Why is land use more important than water use?</h3>
The above question is answered through science because this is a logical question and we know that science answers questions logically and experimentation.
So we can conclude that the first question can be answered by science.
