<span>Perhaps surprisingly, lakes and rivers constitute a tiny proportion of the world's total freshwater, so answer (b) is correct. Most of the freshwater on our planet is in fact locked up in ice and glaciers, some 68%. The majority of the rest, 30%, is actually underground, in springs and other groundwater feeders. That leaves just 2% that makes up all the rivers, lakes, ponds and other visible freshwater reservoirs that we see in our day-to-day lives.</span>
The answer is; D
The simplicity of the prokaryote bacteria cells can depict the origin of life. It is simply composed of microscopic unit enclosed in a plasma membrane and cell wall. The inside contains a small DNA molecule, ribosomes and cytoplasm (they have no organelles). They have been around for 2 billion years on earth before other organisms evolved from them.
Answer:
There is no diagram in this question, however, the question can be answered based on general understanding.
Light energy is converted to chemical energy by PLANTS (GRASS) i.e from the sun to grass
Explanation:
This question is trying to depict a food web or chain of organisms feeding on one another in order to obtain energy. However, in this process, only one organisms amongst the list of organisms is capable of converting LIGHT energy to CHEMICAL ENERGY.
This organism is called a PRODUCER and it is the GRASS (plant). Green plants like the grass in this question are autotrophs i.e. are capable of producing their own food via the process of PHOTOSYNTHESIS. In this process of photosynthesis, plants capture light energy from the sun and convert it to chemical energy stored in sugars.
Replication is when you copy something, and repetition is when you keep doing it over and over again. i hope this helps :-D
Answer:
Yeasts, especially Saccharomyces species, are primarily known from whole cell reductive activity [64, 65] and are used in the food industry for the production of alcoholic beverages as well as for bread fermentation [3]. However, yeasts are a source of enzymes such as: lipases, dehydrogenases, or invertase.
