One primer attaches to the __ end of the gene region on the 5' to 3' strand, another to the ___ end of the gene region of the 3' to 5' strand. This was maybe not explicit in the video. 3’ and 5’ refer to the orientation of the DNA strand. The 3’ end is the end that has the OH group used for adding new nucleotides. The 5’ end is the end where a phosphate sticks out from the ribose. The two strands that make up the DNA molecule run anti parallel to each other. Synthesis is always in the 5’ to 3’ direction (because that is where new nucleotides attach), and the template strand is read 3’ to 5’ (because it runs antiparallel).
Answer:
Explanation:
This question is incomplete however during DNA amplification using polymerase chain reaction, the two primers attach to each DNA strand at the 3' end.
Two primers are used during this process; one primer each for the two complementary strands of DNA (that run antiparallel to each other). The 5' end of each primer is attached to the 3' end of each DNA strand regardless of the direction the strand is running (5' to 3' or 3' to 5'). This process of attaching the primers to the DNA strand is known as annealing.

The diagram below shows the exchange of carbon dioxide (CO2) and oxygen (O2) between a cell and the blood flowing through a capillary.
In this diagram, the molecules of CO2 (represented by x’s) are moving from an area of--
Answer:
From an area of higher concentration to an area of lower concentration.
Explanation:
The molecules of CO2 are moving from an area of higher concentration to an area of lower concentration. Carbondioxide is produced as waste product in the cell during the process of respiration. This carbondioxide gas is loaded in blood cells because in the cell, concentration of carbondioxide gas is higher while on the other hand the concentration of carbondioxide is lower in the blood cells. This carbondioxide gas exchange in the lungs with oxygen which is required in the process of respiration for the production of energy in the form of ATP molecules. So from the conclusion we can say that CO2 moves from an area of higher concentration to lower concentration.

1. Explain how a bacteriostatic antibiotic is useful even if it does not result in the death of the pathogen.
2. Give an example of when you would want to use a broad-spectrum antibiotic and when you would want to use a narrow-spectrum antibiotic. Give a disadvantage to using a broad-spectrum antibiotic.
3. Explain how organisms can develop resistance to chemical disinfectants.
4. Describe how avoiding the use of antibiotics for viral infections can prevent the spread of antibioticresistance.
Answer:
1- the bacteriostatic effect refers to the fact that they stop the metabolism of pathogenic bacteria, which means that they do not reproduce, do not colonize and do not generate the disease.
Bacteria in order to trigger a pathogenic response need to comply with their metabolism and this does not happen in the bacteriostatic effect.
2- Broad spectrum antibiotics where the patient's life is at risk, difficulty swallowing or breathing, and in infections that involve many planes or we are facing an extremely complex buofilm.
Low-spectrum antibiotic, in mild, focal infectious diseases that do not compromise the systemic factor and are suspected of simple or little complex pathogens.
3-Through mechanisms and virulence factors that are transmitted between them. One mechanism is sporulation, the change of essential metabolite, among others.
4- Prevents the spread and resistance because it reduces the bacterial load of pathogenic bacteria that in the future could form bacteruphages.
Explanation:
Broad spectrum antibiotics cover many bacteria, that is, they kill many bacteria of different families and even characteristics, while low spectrum antibiotics are the opposite.
Hyperventilation (rapid inhalation and exhalation) can result in respiratory alkalosis (increased blood pH). Why
Answer:
Because lack of carbon dioxide causes the lack of acidic HCO₃⁻ which help to the regulation of the blood's pH.
Explanation:
Hello.
In this case, since the presence of carbon dioxide in blood regulates the pH of blood by maintaining it at about 7.35 to 7.45 (slightly basic) due to the equilibrium shown on the attached picture by which the yielded HCO₃⁻ ions low down the pH because the lack of CO₂ cause a condition known as respiratory alkalosis in which the pH of the blood significantly increases.
Thus, that condition causes symptoms such as confusion, hand tremor, lightheadedness., muscle twitching, nausea, vomiting and others.

How does the Edge Effect impact biodiversity?
Answer:
In ecology, edge effects are changes in population or community structures that occur at the boundary of two or more habits. As the edge effects increase, the boundary habit allows for greater biodiversity.

Explanation:
during photosynthesis, what is the source of the carbon i the sugar that is created
Answer:
Plants get the carbon from the air that humans exhale. They breath it in and use it for photosynthesis.
Explanation:
Took biology last year.
During photosynthesis, what is the source of the carbon is the sugar that is created is carbon dioxide in the air.
Photosynthesis is the process by which plants use sunlight, water, and carbon dioxide to create oxygen and energy in the form of sugar.Carbon dioxide serves as the source of carbon, and it enters the photosynthetic process in a series of reactions called the carbon-fixation reactions (also known as the dark reactions).Stages of photosynthesis:
(i) Absorption of light energy by chlorophyll.
(ii) Conversion of light energy to chemical energy and splitting of water molecules into hydrogen and oxygen.
(iii) Reduction of carbon dioxide to carbohydrates.

Activity
Fish are sensitive to many environmental variables: dissolved oxygen, light, temperature, pH, clarity of water, food supply, presence of predators, etc. Fish will be attracted to different locations in a lake, based on its mix of variables.
Imagine you want to conduct an experiment to understand how just one of these variables differs in a local lake, depending on its depth. This lake reaches a depth of 17 meters. For this activity:
Pick a variable that might change as you go deeper in the lake on a given day.
Do a little research on that variable to determine how you might measure it in a lake.
Use the template below to outline an experiment to investigate this variable in the lake by depth. For each part, simply answer the question in parentheses to create your outline.

Observations: (What specifically would you look for and record?)
Data analysis: (With this kind of data, what would be the best way to present it?)
Conclusion: [No need to enter anything here for now.]
References: (List any references you used to design the experiment. Note that for a full experiment write-up you’d also list any references you used while carrying out the experiment or in analyzing your results.)
Answer and Explanation:
Variable: dissolved oxygen
Title: Oxygen variation as a water quality indicator.
Purpose: To study how dissolved oxygen varies with depth
Hypothesis: The percentage of dissolved oxygen will decrease as depth increases.
Procedure/Method:
Selection of sampling spots, according to the morphometry of the lake, different depth, water currents inputs and outputs, aquatic vegetation, and lake type of use. In each spot water samples will be taken using a Niskin bottle. The sample will be taken from different depth: 5 meters deep, 10 meters deep, and 15 meters deep (photic zone). Dissolved oxygen (DO) will be measured in each sample, by using a multiparameter sensor. In a field sheet to evaluate the parameter, the %DO by site and depth will be recorded.Observations:
%DO in each site and depth will be recorded in order to analyze how it varies with depth.
Data analysis:
According to different indicators of water quality in a lake, the observed %DO will be compared and analyzed to evaluate the sanity state of the lake water. Example of valuation scale,
NORMAL index: Oxygen concentration in the water column is found to be sufficient for the fish survival
REGULAR: Decrease in oxygen concentration at greater depth, values below saturation in the background
CRITICAL: Null oxygen concentration in all or part of the column profile of water. Probable fish mortality events.
According to the taken data, observations on the study site will be taken, such as the variation in oxygen concentration as it gets deeper, until reaching hypoxia level, where fishes can not survive. Data can be presented in tables and in graphs, in both cases comparing sampling sites and depth, making a focus on the valuation scale.
Conclusion:
Association of the oxygen variation with the sanity state of the lake, microbiology decomposition processes at different depths, eutrophication state, among others.
