What is this for is it biology
Answer:
Chlorophyll is a green pigment found in chloroplast in plants. It absorbs sunlight during the process of photosynthesis. It is a chelate molecule. In a chelate molecule a central metal ion forms bonds with a large organic molecule made of carbon, hydrogen and other elements like nitrogen or oxygen.
In chlorophyll, magnesium is the central metal ion and it is bonded to a large organic molecule called as porphyrin. Porphyrin constitutes four nitrogen atoms to which the central magnesium is bonded in square planar arrangement. Since chlorophyll is responsible for the green color of the leaves, more the green color more the chlorophyll content and more is the nitrogen content. Hence, chlorophyll meter measures this green light and finds out if the plant needs more or less nitrogen.
Sorry me nobody else knew either lollll
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. :)
