Why are you asked to gram stain a mixture of gram positive and gram negative bacteria on the same slide?

Answers

The accuracy of the Gram stain is dependent on the integrity of the bacterial cell wall. Variety of things can influence the cell wall integrity. Suppose the cells have been roughly handled , gram positive cells will come out as gram-negative. If you de-colorize them for too long, Gram-positive cells will look like Gram-negative cells or if you do not decolorize enough, Gram-negatives will look like Gram-positives. Under these circumstances Gram-positive and a known Gram-negative on the same slide so that the results are reliable.
Final answer:

Gram staining is a technique used to differentiate and classify bacteria based on their cell wall structure. By gram staining a mixture of Gram-positive and Gram-negative bacteria on the same slide, you can compare and contrast their staining reactions and overall characteristics.

Explanation:

Gram staining is a technique used to differentiate and classify bacteria based on their cell wall structure. Gram-positive bacteria have a thicker peptidoglycan layer in their cell wall, while Gram-negative bacteria have a thinner peptidoglycan layer. The differences in cell wall composition allow for differential staining during the Gram staining process. Gram-positive bacteria retain the purple crystal-violet stain, appearing purple, while Gram-negative bacteria lose the crystal-violet stain and instead take up the red safranin counterstain, appearing pink.

In the case of a mixture of Gram-positive and Gram-negative bacteria, gram staining on the same slide can help determine the Gram stain reaction, as well as the cellular morphology and arrangement of both types of bacteria. By observing both types of bacteria in a mixed smear, it becomes easier to compare and contrast their staining reactions and overall characteristics.

1. Describe at least one societal issue that scientists will be able to address using the sequence of the human genome.
2. What ethical considerations will arise if this research is pursued?
3. Who should decide whether scientists should pursue research that poses ethical dilemmas?
Explain your response.

Answers

1. One societal issue that scientists will be able to address using the sequence of the human genome is reduction in the number of disable children born.
Using the sequences of human genome, scientists will be able to detect when a woman is carrying a defective or disable baby, this will allow decision to be made whether to abort the fetus or to keep the pregnancy. This will reduce the number of disable children born and reduce the amount of government resources that are been spent on this sector of the society.

2. By using human genome to assess the risk of giving birth to defective babies, the ethical considerations that will arise include the following:
i. Is it good to abort babies? Is that not murder?
ii. Who will make the decision to abort? The parents or the doctor? what of if the  parent want to keep the pregnancy despite the risk? 
These ethical questions will need to be addressed depending on the situations that surround the event.

3. Principally, the government ought to be the one to regulate how the human genome sequence is used by scientists. There ought to be a standard which give clear directives on what can be done and what can not be done.
But depending on the situation of the research involved, if human subjects are going to be used, then their consents must be obtained before the research is carried out. For instance, in the issue of pregnancy risk assessment described above, the woman's consent must be obtained before the pregnancy is aborted.

This experiment result is modified latter because the mass was not only from water but also from the reaction of carbon dioxide.

A 14-month-old child is admitted to the pediatric hospital with a fractured right femur. the child is placed in bryant traction. when the parents see the child for the first time in traction, they are surprised to see both legs in traction and ask why. what information should the nurse share about bryant traction?

Answers

Bryant's traction is the kind of orthopedic traction. It is primarily used in young children who exhibit fractures of the femur or congenital unusualities of the hip. Both the limbs of the patient are vertically suspended in the air at a right angle from the knees and hips slightly flexed.  

This traction is primarily used to minimize the chances of congenital hip dislocation. When the child is positioning on his back, the traction holds the legs vertical and the weight on the traction mildly stretches the legs of the child. This relaxes the tendons, ligaments, and muscles around the hips of the child.

Why is it important to center a speciment on low power before attempting to focus on it at high power?

Answers

It isn't if you're good with the microscope.

But as far as beginners go, it makes things easier. You have a large "field of view" with the small objective (low power). This means you can get it in focus and center the specimen. When you switch to the high objective (high power) then your specimen will already be partly in focus and centered. If you didn't center it with the low objective you would have a difficult time trying to find it since it wouldn't be lined up and completely out of focus.

Binoculars work with the same principle. You don't look down at the ground with the binoculars then swing them up to the sky and try to find a bird. You look at the bird then you put the binoculars up to your eyes, already looking.

_______ completes the formation of two new daughter cells. Telophase Cytokinesis Interphase Mitosis

Answers

Mitosis results in two daughter cells having the same number and kind of chromosomes. 

Answer:

-Cytokinesis.

Explanation:

Cell cycle can be defined as a series of cyclic events, which leads to formation of two daughter cells from a single parent cell. It is divided into two steps, interphase and M phase or mitotic phase.

During interphase, cell replicates its genetic material and prepares for cell division. Mitotic phase is divided into karyokinesis and cytokinesis.

During karyokinesis, division of nucleus takes place to form two daughter cells with same genetic composition. During cytokinesis, division of cytoplasm takes place that completes the cell division and forms two daughter cells.

Thus, the correct option to be filled in the blank is 'cytokinesis.

True or false homogeneous mixtures have uniform properties throughout

The statement above is TRUE.
Homogeneous mixtures is a type of mixture in which the constituent particles are uniformly distributed throughout the mixture, thus an homogeneous mixture has uniform properties throughout.
Final answer:

True, homogeneous mixtures, such as a sugar solution, have uniform properties throughout due to the components being uniformly mixed together.

Explanation:

The statement you asked about is true. A homogeneous mixture is a type of mixture in which the components are so uniformly mixed together that they become indistinguishable from each other. This uniform distribution of components results in homogeneous mixtures having uniform properties throughout. For example, in a sugar solution, the sweetness is uniform throughout, regardless of where you taste it. This is the fundamental characteristic of homogeneous mixtures that distinguishes them from heterogeneous mixtures.

Aaron is 5 years old. what does the u.s. department of health and human services consider to be the most hazardous to his health?

Answers

Final answer:

Lead exposure is a significant health risk to children under six, with no safe blood level of lead in children. It can come from various sources like deteriorating lead-based paint and lead pipes, and children are particularly at risk due to their tendency to put objects in their mouths. Prevention and regular blood screenings are crucial.

Explanation:

The U.S. Department of Health and Human Services, along with other agencies such as the Environmental Protection Agency (EPA) and Centers for Disease Control (CDC), considers lead exposure as one of the most hazardous environmental health risks to children, especially those under six years of age. Lead is toxic and can be found in various sources around the home, including deteriorating lead-based paint, dust, water from lead pipes, and even toys or jewelry. Young children like Aaron, who is 5 years old, are particularly vulnerable because they often put objects in their mouths, which can lead to the ingestion of lead particles or dust.

Parents are advised to be vigilant in preventing lead exposure by ensuring their homes are free from peeling or chipping paint, replacing lead pipes if present, and checking that toys and jewelry are lead-free. Regular screenings for lead levels in blood are recommended for children between the ages of one and two because there is no known safe blood level of lead in children. If elevated lead levels are detected, immediate steps should be taken to reduce further exposure and prevent the harmful effects that can develop later in life.

How much energy is available to organisms on the 5th trophic level compared with those on the 1st

Answers

When a primary consumers eat the producers, part of the energy stored in the plants is transferred to the primary consumers. bout 10% of a producer's available energy is passed to the primary consumer, about 90% of energy is lost to the environment.
Since only 10%of energy is available to each subsequent consumer, the energy level becomes too low to be sufficient enough to sustain the consumers at the end of food chain. Hence, food chain rarely have more than 4 trophic levels.
