C) Biomass
because biomass is a renewabie energy sourc
The answer is A, as most sewage treatment plants use bacteria to break down and remove nutrients. The main water pollution problem caused by sewage effluent is eutrophication, related to the release of nutrients into rivers and lakes. Nutrients such as nitrogen and phosphorus ions result in high algal growth. Some algal blooms release toxins, and algal blooms also disrupt the natural dissolved oxygen concentration cycles. Fish kills are often because eutrophication has resulted in anoxic conditions.
Anyway, wastewater treatment plants utilise bacteria to facilitate nitrification or denitrification, which removes ammonia and nitrates/nitrites, respectively.
The true answer of your question is :
OH : HYDROXYL GROUP
NH2 : AMINO GROUP
CH3 : METHYL GROUP ( but in rather broader terms, that functional group of formula CnH2n+1 where n is an integer is called ALKYL GROUP where by substituting n by 1,2,3... we obtain methyl for n = 1, ethyl for n = 2, and propyl for n = 3 )
COOH : CARBOXYL GROUP is the correct answer since carbonyl is characterized by the presence of functional group C=O in general the formula of the compound would be
R-C=O-R’ where R and R’ are alkyl groups like methyl for example. However the carboxyl group could be thought of as a summation of carbonyl + hydroxyl ( CO + OH ) resulting thus in COOH.
I hope you’ll understand everything, anyway if not i’m always here to help. ♥️
<u>Answer</u>:
Within a population there is always genetic variation. This will give rise phenotypic variation, which are the observable characteristics of an individual.
The environmental variables will put a certain pressure on an individual. Because all individuals vary to a certain degree, their ability to cope with this pressure and survive will also vary.
Thus, organisms whose traits are better suited to the environment will have a higher chance of survival. These individuals will successfully mate and in this way, pass on their genetic information and advantageous traits.
Because of this selection, in time this trait will become dominant within a population. Given enough time, according to the theory of evolution, under the influence of environmental factors, an organism's body will evolve and become more and more adapted to its environment.
Answer:
Explanation:
Taxonomy refers to science which deals with naming, describing and classifying organisms that includes all plants, animals and microorganisms of the world in respect to their similarities and differences. It is a method by which living things are organised into groups. It group organisms into singular taxon.
