AC is the kind of electrical flow we get from a typical electrical outlet in a home. AC is when the electrons flow in two directions, from the positive to the negative terminal and from the negative to the positive terminal, 'alternating' between the two directions.

Which part of the model shows carbon moving from the biosphere to the
atmosphere?
Answer:
A. Decomposers breaking down the material
Explanation:
Decomposition is the process in which decomposers such as bacteria break down the organic material in the atmosphere.
In the given image, decomposers breaking down the material shows carbon moving from the biosphere to the atmosphere because decomposers break down the dead organisms and in the process the carbon in the bodies of dead organism get back in to the atmosphere.
Hence, the correct answer is "A. Decomposers breaking down the material".

Explanation:
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.
can someone give me good evidence please i will give you brainliest
Answer:
you can get evidence by observing how people have different traits from their parents, like one sibling can look different than they other sibling, they can get traits from older generations, like you can have a family that has black hair or dark brown and one of their kids got light brown hair because that was passed down or skipped through a generation.

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.

In a normal respiratory cycle the volume of air that moves into and out of the lungs is about 504 mL. The reserve and residual volumes of air that remain in the lungs occupy about 2030 mL and a single respiratory cycle for an average human takes about 4 seconds. Find a model for the total volume of air V(t) in the lungs as a function of time.
Answer:
[tex]V(t)=252sin(\frac{\pi}{2}t )+2282[/tex]
Explanation:
The volume of air increases and decreases, hence the volume of air can be represented as a sine function.
A sine function is of the form:
y = Asin(B(x - C)) + D
Where A is the amplitude, B is the frequency, C is the horizontal shift and D is the vertical shift.
Therefore, the total volume of air V(t) in the lungs as a function of time is given by:
V(t) = Asin(B(t - C)) + D
Since the volume of air in and out of the longs is 504 ml, hence the amplitude (A) = 504/2 = 252
There is residual air of 2030 ml minimum in the lungs and a maximum of 2534 ml (2030 ml + 504 ml), hence the vertical shift (D) = (2534 + 2030) / 2 = 2282 ml
The frequency B = 2π / 4 s = π/2
Therefore:
[tex]V(t)=252sin(\frac{\pi}{2}t )+2282[/tex]

Review: Fill in the boxes with missing vocabulary Need Help: Click here Polymer Monomer Protein nucleotide
Answer:
This question is asking for the polymer and monomer of nucleotide and protein respectively.
The answer is:
Protein - monomer is AMINO ACID
Nucleotide - polymer is NUCLEIC ACID
Explanation:
There are four major biological molecules found in nature namely: protein, carbohydrates, fats and oil, nucleic acid. These biological molecules are, however, complex and polymeric in nature and like every other polymer, they must contain monomers that make up their structure.
- PROTEINS are made up of monomers called AMINO ACIDS.
- CARBOHYDRATES are made up of monomers called MONOSACCHARIDES.
- LIPIDS are made up of monomers called FATTY ACIDS.
- NUCLEIC ACIDS are made up of monomers called NUCLEOTIDES.

Answer:
Water puts pressure depends on their amount.
Explanation:
In the bottle, there is large quantity of water that put high pressure on the bag present at the side of the bottle that leads to swelling of the bag whereas, if the bag is present at the bottom not at the side and water is also present in large amount so more swelling of bag occurs so we can conclude that more water puts more pressure and less water puts less pressure.

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.
