The answer is false, i took the quiz
<span>So if it's only producing 10 % of the power striking the earth then just wait ten times longer and store the difference to be used later! But then you have to wait even longer while storing even more power because of the cut off caused by night! If day is longer than night then you may win in this race, but you can also use more than one collecter converted which will greatly speed up the entire process! Or you can just use one collector converter and increase the amount of sunlight directed to that one single unit! The point is there are ways to improve the situation and reduce the cost. Just think about it for a moment like I just did! Actually the farther North you are the shorter the payback period! Because you would use it for heating as well!
Is this what you mean?</span>
Answer:
- An element is a pure substance that cannot be broken down into a simpler form.
- All elements are listed on the periodic table of elements.
- An element symbol begins with a capital letter; if there is a second or even third letter, it is a lowercase letter
Explanation:
An element is one of the two types of pure substances i.e. substances that cannot be broken down into simpler forms. Elements are made up of only one type of atom e.g. Fe, Cl2 (two chlorine atoms).
All known or discovered chemical elements are represented on the periodic table. In an order of increasing atomic number, elements are arranged from left to right on the periodic table.
The symbol of an element begins with a first letter written in capital letters while the subsequent letters can be written in lower cases. For example, Fe, Cu, Hg, Zn etc.
Answer:
Explanation:
The animals are used for examining and determining the effect of a particular new drug for the treatment of the diseases and disorders before they are examined over humans. This practice is called as clinical trial.
The ethical issue associated with given type of testing is that animals have right to live and survive. They should not be subjected to the treatment where they experience harm or even death.
Answer:
Oxidative phosphorylation is a process which produces most of ATP that is produced during cellular respiration. Glycolysis produces 2 ATP molecules. Citric acid cycle produces 2 ATP molecules.
Explanation:
Oxidative phosphorylation process is also known as electron transport chain. This process produces ATP in large amount i. e. 28 ATP molecules. This process only occurs in aerobic respiration because this process requires oxygen while glycolysis and citric acid cycle produces only 2 ATP molecules.
