After buying a new house by the lake, a family wanted a better view of the water so they could watch the sailboats. They hired a company to cut down the small trees and shrubs that were blocking the view.
Which type of water pollution is most likely
1 . Nutrient
2.sediment
3.toxic
4. Bacterial
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.
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.

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.
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.

Unlike skeletal muscle, the muscle cells of the heart (called "cardiomyocytes") metabolize very little glucose, relying almost exclusively on metabolism of fatty acids for their energy. Which of the following statements are likely to be true of cardiomyocytes, but NOT skeletal myocytes? (select two answers)
a. low levels of glycogen storage, even when blood glucose is high
b. high levels of glycogen storage, even when blood glucose is low
c. low lactate production, even at high activity
d. high lactate production, even at low activity
e. many mitochondria compared to other cells
f. few mitochondria compared to other cells
Answer: A. low levels of glycogen storage, even when blood glucose is high.
C. low lactate production, even at high activity.
Explanation:
Cardiomyocytes are also known as the myocardiocytes. They are the cells which makes up make up the muscle if the heart. They're responsible for the generation of the contractile force in the heart which helps in the pumping if blood.
From the options given, the statements that are likely to be true of cardiomyocytes, but not of skeletal myocytes include:
• low levels of glycogen storage, even when blood glucose is high.
• low lactate production, even at high activity.
Answer:
The answer is A and C
Explanation:
Since cardiomyocytes are dependent on fatty acids, they rely on oxidative phosphorylation to generate energy, and consume very little glucose. Due to this, they have very low need for fermentation of pyruvate. In fact, they can absorb lactate generated by skeletal myocytes and erythrocytes and oxidize it for additional energy. Another consequence of this metabolism is that cardiomyocytes store little or no glucose as glycogen.
Skeletal myocytes and cardiomyocytes both have high energy needs and thus have more mitochondria than other cells. Cardiomyocytes have an even greater density of mitochondria than skeletal myocytes because they depend almost entirely on oxidative phosphorylation for their energy needs. This dependence on oxidative phosphorylation also explains the extraordinary sensitivity of cardiac muscle to hypoxic (low-oxygen) events. Without oxygen, cardiomyocytes rapidly run out of energy and can quickly die.

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.
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.

Explain how a bottleneck event can enrich recessive traits in the genetics of a population.
Answer
A bottleneck event severely reduces the fraction of a species able to pass on their genes to offspring. Any once rare recessive traits present in the surviving breeding population are passed to a larger fraction of the total population of offspring, thereby enriching those recessive traits in the total gene pool .
Bottleneck events can limit variation if the dominant allele population gets wiped out for any reason and the recessive allele can appear to be in the majority however this does not shows the actual makeup of the population.
What is bottle neck effect?The bottleneck effect is defined as a reduction and subsequent increase in a population's size affects the distribution of genetic variation among its individuals.
Examples of bottle neck effect is when the northern elephant seals have reduced genetic variation likely because of a population bottleneck humans imposed on them in the 1890s. Hunting reduced their population size to as few as 20 individuals at the end of the 19th century.
