Answer:
Aquifers but since there is no answer choice I say groundwater .
Hope this helps .
Water located in wells underground is ground water. Therefore, the correct option is option C.
Water that is found below the earth's surface in cracks in rocks and the crevices between soil particles is known as groundwater. It is essential for maintaining ecosystems on our planet and supporting human activities. Groundwater is created and made available by precipitation and surface water that seeps into the ground. It gathers in subterranean aquifers, which are enormous water reservoirs contained in permeable rocks or sediments. The thickness and depth of these aquifers vary. Groundwater supply is influenced by elements like rainfall, geology, and human use. Groundwater is an important resource since it is necessary for a variety of purposes. It provides over half of the world's population with their main supply of drinking water.
Therefore, the correct option is option C.

Describe how the EMG signal (a voltage) arises from muscle activity
Answer: The EMG signal is a biomedical signal that measures electrical currents generated in muscles during its contraction representing neuromuscular activities. The nervous system always controls the muscle activity (contraction/relaxation). ... EMG signal acquires noise while traveling through different tissues. EMG signals are recorded by placing electrodes close to the muscle groups. When the muscle is activated, the length of the muscle decreases and the muscle, skin and electrodes move with respect to one another. At that time, the electrodes will show some movement artifacts
Explanation:
EMG signals are recorded by positioning electrodes close to the muscle groups. It is the arrangement that helps in the monitoring of EMG signals from muscle activity.
What do you mean by EMG signals?EMG signals may be defined as a biomedical signal that estimates electrical currents provoked in muscles during their contraction illustrating neuromuscular activities.
When the muscle is stimulated for any mechanism, the length of the muscle declines, which leads to the muscle, skin, and electrodes moving with regard to one another.
The EMG signals always arise from the electrical activity of the muscle fibers which are stimulated during the time of contraction.
Therefore, EMG signals are recorded by positioning electrodes close to the muscle groups. It is the arrangement that helps in the monitoring of EMG signals from muscle activity.

How would adding finer particles to the sand affect porosity?
Explanation:
Porosity depends on the size, shape, and mixture of grains and particles that compose soil and rock. For instance, small particles such as clays can compact more closely together, reducing the amount of porosity. However, larger particles such as sand and gravel will have more spaces available between them.
In humans, nearly 80% of proteins are acetylated on their N-terminal residue, a modification known to be recognized by a specific E3 enzyme, which directs the ubiquitylation of the protein for rapid degradation. Does this mean that all of these proteins would be actively degraded at the same time
Answer:
Yes
Explanation:
Yes this means that all of these proteins will be actively degraded and this is due to the high turnover rate which will ensure that their activity will be under tight control.
The acetylation of the N-terminal of the protein, with the Ubiquitylation of the protein by an E3 enzyme, helps in the maintenance of the homeostasis of protein activity.
In the late 1980s and early 1990s, the percentage of Icelandic children whose bacterial infections were caused by bacteria resistant to penicillin rose at an alarming rate. After public health officials initiated a campaign to reduce the use of penicillin, resistance dropped off. This observation is consistent with the hypothesis that ________.
Answer:
The correct answer would be - "bacterial populations evolve in response to the selection pressure imposed by antibiotics".
Explanation:
The given information provided in the question about the bacterial infection supports the hypothesis that the bacterial population shows the evolution in response to the selection pressure caused by the antibiotics due to the fact that bacteria increased resistance gradually with time. This resistance towards antibiotics increased the percentage of bacterially infected children in the late 1980s and early 1990s.
In this case, the population of bacteria having resistance genes is selected to evolved selected to increase their offsprings.

Explanation:
If all of your cells have the same complete set of DNA why do different cells in different proteins
Why do we have different cells in our bodies if every cell has the same DNA?
The genome of a cell contains in its DNA sequence the information to make many thousands of different protein and RNA molecules. A cell typically expresses only a fraction of its genes, and the different types of cells in multicellular organisms arise because different sets of genes are expressed.

Discribe blood cells and give their proper function. what makes difference on red blood cells to other types of cells of human?
Answer:
white blood cells help in the body in this action is to fight against diseases in the body while red blood cells help transport oxygen and nutrients in body
Blood cells and supply their proper feature: The red blood cell's important feature is to carry oxygen from the lungs and supply it during our body. red blood cells additionally transport waste including carbon dioxide returned to our lungs to be exhaled. Red blood cells can convey oxygen because of a protein known as hemoglobin.
How are human red blood cells exclusive from all different human cells?Red blood cells are microscopic and feature the shape of a flat disk or doughnut, that is round with an indentation within the middle, however it is not hollow. red blood cells do not have a nucleus like white blood cells, allowing them to change shape and flow for the duration of your body less difficult.

Which of the following is a true statement? Physical property change is always better than chemical property change.
o Physical and chemical propery change can happen at the same time.
Chemical property change is better than physical property change.
Answer:
the second one
Explanation:
Sometimes it can be tricky to know whether or not a chemical reaction has occurred. For example, when you melt ice into water, you can write the process in terms of a chemical reaction. However, the chemical formula on both sides of the reaction is the same. Since the chemical identity of the matter in question is unchanged, this process represents a physical change.
Thus melting point is a physical property. On the other hand, flammability is a chemical property of matter because the only way to know how readily a substance ignites is to burn it. In the chemical reaction for combustion, the reactants and products are different.
none are better, depending on for what

What is the term used for genetic mutations that may result in neutral or even negative outcomes?(1 point)
A) genetic drift
B) natural selection
C) artificial selection
D) genetic modification
Answer:
Genetic Drift
Explanation:
Evolutionary change can and does occur without natural selection. This usually occurs as a result of genetic drift: genetic mutations that may result in neutral or even negative outcomes.
The term 'GENETIC DRIFT' is used for genetic mutations that may result in neutral or even negative outcomes (Option A).
Genetic drift refers to random fluctuations in the frequency of a given gene variant (i.e. an allele) and different genes in the individuals that form a population.Genetic drift may occur on neutral or negative alleles carried out by the individuals of a population.These random fluctuations cause changes in the allele frequencies, which are fixed when they reach a frequency equal to one (1).In conclusion, the term 'GENETIC DRIFT' is used for genetic mutations that may result in neutral or even negative outcomes (Option A).
