The midpoint of range is 3000. Yes, in from 1950-1955 there was a massive increase of the population of chipmunks but from then on it slowly decreased until 1990. In 1995, the population doubled from 1990. If you double 1440, you will get 2880. The biologist said between 2900-3100, using the midpoint of this range (3000) it is too low therefore being a bit unreasonable.

change the hypothesis if mussels died in
both aquariums?
Answers
The new hypothesis could be that there is another alternative factor that is negativey afecting dwarfs survivorship.
The previous hypothesis of high levels of phosphate killing mussels is not necessarily disproved. But the death of mussels from both the control and the treatment groups might be related to one of the controlled variables that could be actually afecting them.
----------------------
Probably different levels of phosphate are also affecting invididuals´ survivor rates. However, the fact that mussels from all the aquariums died suggests that there is something else going on that caused the death of all the individuals.
The control group is used to identify any other factors influencing the results obtained in the study, apart from the modified variables of the treatment. Individuals of the control group are selected from the same population as the treatment group. These two groups are identical in all aspects except for the independent variable, which changes in the treatment group but remains constant in the control group.
We know that mussels in this experiment were taken from the same population and grown under the same controlled conditions. Only the treatment group received phosphate, but all mussels died, not only the ones that receive phosphate. This result turns to be useful because it is indicating that there is another variable that is killing mussels. Phosphate might be a cause of death, but there is also something else. So the researchers should pay attention to the controlled variables, such as water quality, temperature, pH, food supply, light exposure, or others.
These variables might be reflecting the real conditions under which mussels live. The results tell that one of these is related to individual death and could be a consequence of climate change or soil use, among other causes.

One of the great mysteries of our Solar System is why Uranus is tilted on its side. Surely, if the solar system formed from the same rotating cloud of dust and gas, then all the bodies within it should rotate in the same way. And yet Uranus’ axis of rotation lies at 97 degrees to the plane of the solar system.
Direct counts of cells in liquid samples can be performed using a Petroff-Hausser counting chamber. Research this method and describe how it compares to the viable plate count method of determining the number of CFU in a sample.
Answers
The viable plate count is the most commonly used method to estimate the number of viable cells in a sample; while the Petroff-Hausser counting chamber is a direct microscopic count method generally used for counting bacteria and sperm cells.
The Petroff-Hausser counter is a counting chamber used to count microorganisms and cells (e.g., bacteria and spermatic cells) under the microscope.
The Petroff-Hausser counter chamber is divided into 25 large squares which are in turn divided by double lines. Moreover, within each large square, there also are 16 small squares divided by single lines.
Petroff-Hausser counting chambers are often used to directly determine the number of bacteria in a culture or liquid medium. Petroff-Hausser counting chambers are used to count the number of cells in a given volume of culture liquid by observing 10 to 20 microscope fields.
The viable plate count, also known as simply plate count, is the most commonly used procedure to estimate the number of viable cells in a sample.
The viable plate count method consists in obtaining serial dilutions of a sample having viable microorganisms/cells which are plated onto a growth medium.
This method (viable plate count) can be used to determine the number of actively dividing cells.

Which type of water pollution is most likely
1 . Nutrient
2.sediment
3.toxic
4. Bacterial
Answers
The water pollution that is most likely to occur is Nutrient pollution
Pollution can be defined as the addition of materials or energy (pollutants) to the environment that damages it, making it undesirable or unfit for life. There are different types of pollution which includes:
--> Air pollution
--> Radiation pollution
--> soil pollution and
--> water pollution.
WATER POLLUTION is defined as the type of pollution that occurs when pollutants are being released into water bodies such as streams, lakes, ocean, beaches making it unsafe to use for both human and aquatic life activities. Depending on the type of pollutants, there are also different types of water pollution, these include:
chemical pollution Groundwater pollutionsediment pollutionmicrobiological pollutionnutrient pollutionsurface water pollution and Oxygen-depletion pollution.NUTRIENT pollution occurs when there is EXCESS of it in the water bodies through organic fertilizer or compost manure from the leaves of the cut down trees and shrubs. When nitrates from the agricultural waste gets into the water body(lake) it can cause a drastic increase in aquatic plant growth, especially algal growth. This excessive growth can lead to a decrease in oxygen level of water they by affecting the aquatic life of the lake.
Therefore the CORRECT OPTION is A Nutrient pollution.
Option B is wrong because sediment pollution is a type that involves loose sand, clay, silt, and other soil particles that are carried from a site by runoff water not from cut down trees.
Option C is wrong because toxic or chemical pollution is caused by chemicals from industrial wastes.
Option D is wrong because it is caused by natural existing bacteria in the water bodies and are capable of causing disease when ingested. Example Vibro cholera bacteria.

Suppose a researcher introduces a mutation into the glucosidase domain of the mammalian glycogen debranching enzyme. The mutation inhibits the activity of the glucosidase but does not affect the other functions of the enzyme. The researcher then introduces the mutated enzyme into mammalian cells that do not express wild type glycogen debranching enzyme. Predict the effect of the mutation on glycogen metabolism.
Answers
Answer:
cells will have glycogen molecules with branches of a single glucose residue
Explanation:
Glycogen debranching enzymes are proteins that catalyze the removal of branching from glycogen, which is a multibranched polysaccharide composed of glucose units and serves as a form of energy storage. These enzymes have two catalytic activities on a single polypeptide chain: glucosyltransferase and glucosidase activities, which are both required for glycogen breakdown. Glycogen degradation requires both glycogen phosphorylase and glycogen debranching enzymes. First, a glycogen phosphorylase acts to digest a glycogen branch down to four glucose residues. Subsequently, the debranching enzyme through its glucosyltransferase activity acts to transfer three glucose residues to a nearby branch of the glycogen chain. Finally, through its glucosidase activity, the debranching enzyme cleaves the remaining α-1,6 linkage in order to release free glucose.

As with most fluid samples sent for microbiological analysis, Mandy starts her investigation with a Gram stain.
Gram Stain Analysis Classify the infectious agent based on the Gram staining.
Answers
Hi. Unfortunately your question is incomplete and you have not shown any photos of the sample that Mandy must identify by Gram stain. However, after researching her question on the internet, I was able to find another question exactly like this one, which showed the microorganism that should be analyzed. This image is attached below. In that case, I hope the answer below can help you.
Answer:
Gram-positive cocci
Explanation:
It is possible to identify that the microorganism presented is a bacteria due to the application of the test known as Gram stain, which allows the identification of gram positive and gram negative bacteria. This test allows the bacteria to be subjected to a specific dye that reacts with the chemical composition of the bacteria, modifying its color. Gram positive bacteria show a blue color after the test, while gram negative bacteria show a red color after the test.
As we can see in the attached image, the bacteria that Mandy is analyzing shows a blue color, after being submitted to Gram stain, being then a gram positive bacteria.
We can also see that the colonies of this bacterium have formed round, similar to a coconut and for this reason, we can conclude that the bacterium has the shape known as cocci.
Therefore, we can classify the microorganism as a Gram-positive cocci.
In eukaryotes, miR-5 is a microRNA with sequence complementarity to the 3’UTR of the mRNA transcript encoded by the UCD gene. The UCD gene encodes for a protein that acts as an allosteric activator of the protein p101. The p101 protein is a DNA methyltransferase (DNMT) which is an enzyme that methylates DNA when the protein is in its active form.
A) In a lung cancer cell line, the p101 protein is overly active leading to misregulation of gene expression. In these lung cancer cells which of the following would be a correct prediction in regards to miR-5? [choose ALL that apply, note that incorrect selections will deduct points]
A) The gene encoding miR-5 is in a region of chromatin with hypoacetylation
B) The gene encoding miR-5 is in a region of chromatin with hyperacetylation
C) The gene encoding miR-5 in a region of euchromatin
D) The gene encoding miR-5 in a region of heterochromatin
E) The miR-5 transcript is translated at high levels
F) The miR-5 transcript is activating translation of the UCD gene
B) A different lung cancer cell line is found to have significantly decreased amounts of DNA methylation. Which of the following could explain why there is decreased DNA methylation in this cell line? [choose ALL that apply, note that incorrect selections will deduct points]
A) increased amounts of the p101 protein due to low levels of miR-5
B) increased amounts of the UCD protein due to high levels of miR-5
C) decreased amounts of the UCD protein due to low levels of miR-5
D) the absence of the UCD protein due to miR-5 inhibiting translation of the UCD mRNA transcript
E) the absence of the p101 protein due to miR-5 inhibiting transcription of the p101 mRNA transcript
Answers
Answer:
A) A) The gene encoding miR-5 is in a region of chromatin with hypoacetylation.
D) The gene encoding miR-5 in a region of heterochromatin.
B) D) the absence of the UCD protein due to miR-5 inhibiting translation of the UCD mRNA transcript
Explanation:
MicroRNAs (miRNAs) are small regulatory RNA sequences (approximately 20-24 nucleotides in length) that regulate gene expression by RNA interference (RNAi) mechanisms. These sequences (miRNAs) bind by base complementarity to messenger RNAs and thus inhibit protein translation and/or trigger mRNA degradation. In this case, miR-5 binds to the 3’UTR of the mRNA transcript of the UCD gene, thereby inhibiting/slowing protein UCD synthesis. The UCD protein is an allosteric regulator that binds and activates the expression of the p101 protein, thereby the miR-5 RNAi pathway also indirectly decreases the expression of the p101 gene. Moreover, hypoacetylation is an epigenetic mark generally associated with gene silencing (heterochromatin is a transcriptionally inactive state of chromatin).
