Answer: B. great impact when humans use alternative water sources for non drinking functions.
Great impact when humans use alternative water sources for non drinking functions is the correct option because use of alternative water sources can deplete the overall available water for the present as well as for the future generation of the human population. This is against the concept of sustainable development which suggests that natural resources should be used in such a way so that these can meet the needs of the present population as well as that of future generation.
Eukaryotes always have a cell membrane, but prokaryotes don't. Eukaryotic and Prokaryotic cells are both
building blocks of life in different organisms. The main difference of two is
in its structures. Eukaryotic cells contain organelles that are found
inside membranes, like the nucleus, which stores chromosomes and DNA.
Prokaryotic cells don't have a nucleus and no true chromosomes. Prokaryotic cells
are unicellular while eukaryotes are multicellular. The presence of
mitochondria, chloroplasts, and cell wall are all distinct to Eukaryotic cells.
Eukaryotic cells are found in animals and plants, while bacteria and archaea
have prokaryotic cells.<span>
<span>In terms of existence, prokaryotes have been on
Earth for millions of years; while eukrayotic cells have come to existence
through the process of evolution. </span></span>
Food proteins are used most efficiently when we : ( B ) consume enough carbohydrates and fats to meet our kilocalorie needs
<h3>Our Kilocalorie needs </h3>
Our kilocalorie needs vary between male and females. An average male needs about 2700 kcal per day while a woman needs about 2200 kcal per day to function properly. In order to meet this kilocalorie needs we have to consume the essential nutrients such as carbohydrates and fats and proteins.
Hence we can conclude that Food proteins are used most efficiently when we consume enough carbohydrates and fats to meet our kilocalorie needs
