See that river on the bottom? That water has been flowing in the canyon for a long time and has slowly been chipping away at the rocks to give what you see today.
B. erosion from the water
True.
In the upper layers of the atmosphere, it blocks UV radiation from the sun; however, in the lower layers, it is a pollutant.
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. :)
Answer:
e. unique three-dimensional shape of the fully folded polypeptide.
Explanation:
The tertiary structure of a protein is the unique three-dimensional structure which emanates from the interaction between the “R groups” of the several amino acids that make up the polypeptide. Hydrogen bonding is one of the interactions that occur that gives the protein this structure. Other interactions are ionic bonding, dipole-dipole interactions, hydrophobic interactions, among others. The function of a protein is dependent on its tertiary structure, as a disruption of the tertiary structure causes a protein to be denatured, thereby rendering the protein not functional.
