Power plants (especially fossil-fuel based coal and gas-fired units) are frequently mentioned sources of environmental problems. List three specific types of outputs to the environment resulting from these fossil plants. Which other parts of the life cycle of producing electricity from fossil plants also contribute to these problems
Answer:
Effects of Conventional (fossil fuels & gas fired) power plants : Air pollution, Water Pollution, Land Degradation
Explanation:
Fossil power plants, that use fossil fuels for electricity generation, have various ill environmental effects
Air Pollution - Coal Power Plants emit many polluting gases into environment. Like Sulphur Dioxide, Carbon Monoxide etc, Nitrogen Oxides. The last gas is majorly emitted during process of nitrogen combustion.
Water Pollution - Coal washing process before placing it in boiler (for heat generated electricity) , circulates the same unclean water into water bodies & groundwater.
Land Degradation - The after process disposal mechanism implies untreated water & air pollutants released indiscriminately. This adversely effects the land quality & the wildlife.

5.Write observation and conclusion of each of the following activities
Answer:
Water puts pressure depends on their amount.
Explanation:
On the left side, there is less quantity of water in the tube that put less pressure on the bag present at the bottom and the bag swells slightly while on the other hand, on the right side, there is more amount of water in the tube that puts large pressure on the bag located at the bottom and as a result it swells higher than the other bag so we can conclude that more water puts more pressure and less water puts less pressure.
How does the speed of flowing water affect its ability to erode
HELP PLZZZ!!!
Answer:
Moving water also picks up and carries particles of soil and rock. The ability to erode is affected by the velocity, or speed, of the water. ... As water slows, larger particles are deposited. As the water slows even more, smaller particles are deposited.Explanation:
1. What effect does air pressure have on wind movement?
2. What happens to the density of air as it is heated?
3. It’s a hot, sunny morning in a coastal town in South Florida. Warm air is rising up from the land. Large, puffy clouds are forming overhead. Which way do you think the wind will be moving this afternoon, and what do you think will happen to the temperature?
Answer:
1. The lower the air pressure the faster the wind the higher the air pressure the slower the winds
2. When the heat of the air increases the density of the air decreases.
3. The air above the ocean will, therefore, be warmer and of low pressure than that over land which will be cooler and of relatively higher pressure. Winds will, therefore, blow seawards because winds blow from high to low-pressure systems.
Explanation:
Since Asha is a healthy woman in her forties, she does not have Niemann-Pick disease type A. For this question, assume that she is a healthy person who is a carrier. If Asha is a carrier of the allele for Niemann-Pick disease type A, what is her genotype?
Answer:
Aa is her genotype
Explanation:
This is because since she is just the carrier and she is healthy, her genotype will be heterozygous with the allele for Nieman pick up disease recessive because it's effect is been masked by the allele that is not Nieman pick up disease because it is dorminant. Therefore , the allele for healthiness is dorminant over allele for Nieman disease.

18) The enzyme poly-A polymerase is responsible for adding 3' poly-A tails to eukaryotic mRNAs. This enzyme... A. cuts the mRNA after recognition of the cleavage/polyadenylation signal by CstF and CPSF proteins. B. polymerizes the tail using an RNA template that is part of the enzyme. C. isthesameaspolII D. normally adds about 2000 A nucleotides to the mRNA. E. uses A TP as a substrate.
Answer:
The correct answer is - option e. uses ATP as a substrate.
Explanation:
Poly-A Polymerase is an enzyme of the family of the DNA polymerase beta (polβ) family which catalyzes the reaction of the addition of AMP from ATP to the DNA polymerase beta (polβ) family.
ATP+RNA-3'OH--------->Pyrophosphate + RNApA-3'OH.
In this reaction, after the mRNA is cleaved, the Poly-A Polymerase template-independently adds about 200 A nucleotides (from ATP) one by one.

which of the following is NOT a nucleic acid ?
a. DNA
b. mRNA
c. tRNA
d. Protein
Answer:
reverse transcriptase
Explanation:
The following is NOT a nucleic acid is - d. protein as it is a different macronutrient or macromolecule to nucleic acid.
Nucleic acids are macromolecules of a special class found in all living organisms and also in viruses. There are two types of major nucleic acids, DNA or deoxyribose nucleic acid and RNA or ribose nucleic acid.
Nucleic acids play a role in genetic materialnucleic acid helps in protein synthesisRNA is mainly three types mRNA, messenger RNA, tRNA transfer RNA, and rRNA ribosomal RNA.DNA is normally double-strandedProtein on other hand is a different class of macromolecules that perform many roles in the cell such as, structure, function, and regulation.
Thus, the correct answer is - D. protein.

Answer:
c
Explanation:
the question is asking about the energies. when the two cars are moving towards each other they are accelerating meaning they have kinetic energy. when they collide; on rebounding, the car regains a smaller amount of kinetic energy – this time travelling backwards. So the overall process is that kinetic energy becomes heat and spring potential energy, which results in heat, smaller kinetic energy and, hopefully, surviving occupants. so the speed of the car before and after will show the energy change
