Answer:
Environmental Sciences is a multidisciplinary academic field that integrates biological, physical and information sciences for the study of the environment and solutions to environmental problems. These sciences include physics, ecology, zoology, biology, chemistry, mineralogy, oceanography, geology, soil sciences, atmosphere sciences and geography. The environmental sciences emerged from the fields of natural history and medicine. Today, they allow an integrated, quantitative and interdisciplinary approach to the study of environmental systems.
Related areas of study include environmental studies and environmental engineering. Environmental studies integrate social sciences to understand human relations, perceptions and policies regarding the environment. Environmental engineering focuses on design and technology designed to improve the quality of the environment. Environmental problems almost always include the interaction of physical, chemical and biological processes. Environmental scientists work on topics such as understanding ground processes, assessing alternative energy systems, controlling and mitigating pollution, managing natural resources and the effects of global warming, applying systemic analyzes to environmental problems.
Environmental sciences became an active field of scientific research in the 1960s and 1970s, due to the need for a multidisciplinary approach to analyzing complex environmental problems, the emergence of various environmental laws requiring specific research protocols, and increasing public awareness. the need for action to solve environmental problems.
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. ♥️
The light-dark cycle caused by the rising and setting of the sun is responsible for what are called circadian rhythms. These are biological processes that show a cycle of around 24 hours, the time between consecutive rising of the sun. Experiments have shown that without the external cue of sunlight, the circadian rhythms of organisms tend to break down. These can be reset by being re-exposed to these cues. Jet lag is due in part to a re-setting of the circadian rhythm, as you travel to a different time zone, your body has to become used to a different timing of night and day. <span> </span>
Answer:
The correct answer is: D) The kidneys are paired organs that regulate water and electrolyte balance in terrestrial vertebrates.
Explanation:
The kidneys are the organs that control, for example, <u>the volume of body fluid compartments, acid-base balance, and electrolyte concentrations. </u>These organs are also key to <u>eliminate the toxins from the body. </u>
The kidneys are always two (when not is because of a pathology or the surgical removal of one of the two) and are present in vertebrates.
The kidneys <u>do not regulate blood glucose</u>. That is the job of the pancreas through two hormones called insulin and glucagon.
The kidneys <u>do not remove nitrogenous wastes</u> (urea) from the urine, instead they filtrate these wastes from the blood for these to be excreted through urine.
