Answer:
A. Water molecules are split.
Explanation:
The light dependent reactions of photosynthesis require the energy in sunlight to proceed. Structures called photosystems which contain chlorophyll absorb the light from the sun to generate excited electrons, which are transferred to electron carriers ATP and NADH.
These electron carriers are used in the light-independent reactions of photosynthesis.
During this process, the high energy electrons are passed to an acceptor molecule and replaced with an electron from water. This splitting of water produces H+ ions and oxygen as a byproduct. The splitting of water is called photolysis
The scientist that thought he had proven that plants obtain their nutrients from water rather than soil is Van Helmont.
Julie listed out fossil fuels are a non-renewable source of energy and Fossil fuels are becoming more expensive.
Option C
<h3><u>Explanation:</u></h3>
Fossil fuels are defined as the type of non renewable energy which is formed as a result of dead and decaying organic matter over thousands of years under pressure and temperature of Earth’s core.
This type of fuels are formed due to the dumping of dead prehistoric organisms like dinosaur and others under the soil under a tremendous pressure and very high temperature, where they are acted upon by bacteria and other chemicals to reduce them into petroleum and coal. These are totally non renewable and they are getting expensive over days due to shortage of availability.
To answer this question you must break apart the words given on the right.
“Eco” means life and production. So an ecologist would be someone who studies life and it’s processes. So the correct answer for the first blank would be C. Life Science.
A chemist is one who interacts with day to day elements and sciences that is tactile. So the most appropriate answer would be B. Physical science.
A geologist is someone who studies the earth. As the part of the word “geo,” meaning earth, suggests. So the correct answer here would be A. Earth science.
Finally, “Astro” means space .Astrology is the study of the stars and the sky, for example. So, D. Space science would be the best answer for an astronaut.
I hope all of these are helpful. :)
