Answer:
Each unit of decrease has an exponential increase. So if you are looking at an item that has a Ph of 4 and water has a Ph of 7 —-that means it is 10 to the 3rd power more acidic or 1000 times more acidic than water.
Explanation:
A decrease of one unit on the pH scale means a solution is ten times more acidic; a decrease of two units means the solution is 100 times more acidic; so pH 4 means the solution is thousands of times more acidic than normal water.
What is the effect of pH on the cell?The pH scale shows the pH from 1 to 14, where pH 7 is taken as neutral, below which the solution is more acidic, and above which the solution is more basic. The pH has an important role in the organism as it regulates the blood and maintains enzymatic function.
Hence, a decrease of one unit on the pH scale means a solution is ten times more acidic; a decrease of two units means the solution is 100 times more acidic; so pH 4 means the solution is thousands of times more acidic than normal water.

What is the definition of the length constant? What does the length constant tell you in terms of the electrical signal? Neurons are designed to maximize the length constant – why? What aspect of a neuron’s cable properties are manipulated to maximize the length constant? How are neurons modified (i.e. what is done to the structure of the neuron) to maximize the length constant?
Answer:
The overview of the given problem is outlined in the following section mostly on explanation.
Explanation:
The constant length seems to be a constant value which used to measure the distance between the grade electron density and the neurite through passive electron flow. The larger the quality of the distance constant, the faster the potential goes, throughout consideration of the electronic current.
The electronic replacement through one potential from neighboring areas including its cell will lead with the spatial description by a broad constant of length. This length decreases with either the size of that same neuron rising.The length constant, means of characterizing how much continuous current that flows extends until it bursts out from the axon, despite constants of limited period meaning leakier axons. The resistance of that same membranes should be just as efficient as possible as well as the tolerance of its axoplasm or extracellular media must be weak to enhance the efficient movement of current via an axon.To be effective, key choices must be

why the bio remediation is a series of processes for wastes?
Answer:
It is a series of processes for waters because it break down organic substances in water so that it will not result or cause pollution when water is released into the environment.
Explanation:
Bio remediation is a natural process in which microorganisms is use to clean and treat contaminated water, soil and surface. This process ensure the growth of microorganisms that feed on the contaminants present in the such contaminated media. It can be use to kill oil souls and other contaminated media. It is use as series of process in water so as to break down organic substances or contaminants in water so that it will not cause pollution when the water is released.

Which of the following best explains how a hurricane can increase an area’s susceptibility to future storms? a. Storm surges cause massive damage to buildings along coastlines. b. Hurricanes often flood coastal communities. c. Hurricane strength winds cause large amounts of property damage. d. Erosion caused by hurricanes can leave coasts more exposed to storms. Please select the best answer from the choices provided A B C D
Correct answer choice is:
d. Erosion caused by hurricanes can leave coasts more exposed to storms.
Explanation:
Important erosion, rapture, and removal of solids happen through storms. Beach erosion is a typical consequence of the high waves that transpire when hurricanes pass onto land. The decline of sand makes the beach to grow narrower and deeper in elevation. Storm loops take the sand offshore, keeping and depositing the sediment in great sandbars.

If a plant has a genotype Rr, what is the probability it will produce a gamete that’s is R?
A) 25%
B) 50%
C) 0%
D) 100%
Answer:
B 50percent I think
Explanation:
correct me if I'm not sure
If a plant has a genotype of Rr, then the probability that it will produce a gamete that is R is 50%, which is present in option B. 50% represents the R, and the remaining 50% represents the r.
What are the gametes?The gametes are the products of the cells that undergo meiosis, and by the law of segregation, the alleles can segregate and the gametes are formed by the law of independent assortment. The alleles in this case are the R and r that are present on the chromosomes, and according to the segregation rule, half of the cells get the R allele and the other half get the r type of allele.
Hence, if a plant has a genotype of Rr, then the probability that it will produce a gamete that is R is 50%, which is present in option B. 50% represents the R, and the remaining 50% represents the r.
