Answer:
The answer is A.
Explanation:
A and C have parts that are not directly said by the atricle. D mentions that it says double, which is not directly related to it too. A is something we can determine is true based on the relationship we know between the ocean and fish.
Many (not all) of the greatest scientific discoveries found till this day have been discovered under unethical methods or proceedings. Unfortunately, many as well have been discovered through unethical experimentations for research purposes. However, now there are associations dedicated to approve scientific research ideas before they undergo proceedings of the scientific method in order to prevent more unethical research being done. Within the science community, we are greatful for what we've come to know... however, greatly disappointed with how many of those discoveries came about. Therefore, thanks to these associations, there should be no more unethical practices, experimentations, or research (although there are still quite a few going on in the world). That being said, yes... I believe scientists should definitely be ethical with their work. Otherwise, there will be consequences they shall face.
Osteoporosis is a condition that makes bones more porous, which makes them more brittle and likely to break.
Answer:
By using carbon-14 in the experiment in order to prove the statement.
Explanation:
Translocation occurs in the plant body in order to transport amino acids and sucrose from one part to another by the phloem tissues. In order to prove this, we have to incorporate radioactive element in the amino acid or sucrose which shows us that through which layer the amino acids and sucrose move in the plant body. For this purpose, carbon-14 can be used to trace the path of the translocation of amino acids and sucrose. Through this experiment we will find out that phloem layer is the path used by the plant to move amino acids and sucrose from one part to another.
Answer:
Harry will take 21 seconds
Explanation:
Speed = distance covered / time taken
Harry covers 12 miles in 6 minutes so,
the speed of Harry will be 12/6 = 2 miles per minute.
Therefore, if he covers 0.7 miles then time taken by him will be,
Time taken = distance covered / speed
= 0.7 / 2
= 0.35 minutes
= 0.35 x 60 seconds
= 21 seconds
I hope this helps :)
