Goggles or appropriate safety glasses protect the eyes from:
a. chemical splashes
b. fumes of preservatives used on anatomy specimens
c. UV exposure when using UV radiation in the laboratory
d. burns from the hot plate or Bunsen burner
Answer:
A) chemical splashes
C)UV exposure when using UV radiation in the laboratory
Explanation:
Goggles as well as safety glasses can be regarded as a form of protective eyewear which helps to enclose and protect every area of the eyes to prevent particulates, chemicals as well as water from striking the eyes in the laboratory or in the field. Eyewear is used to prevent chemical splash during experiment, it can prevent exposure of UV radiation from entering the eye in the laboratory.
In order to protect our eyes using
Goggles or appropriate safety glasses, we must take this into consideration.
✓protective eyewear must be put on when required
✓ check the goggles to ensure its in good condition before using it and after using it.
✓ make sure the eyewear is fitted properly.

Describe the immediate effect of the neurotoxin on the number of action potentials in a postsynaptic neuron. Predict whether the maximum membrane potential of the postsynaptic neuron will increase, decrease, or stay the same.
Answer:
Inhibit control over ions.
Explanation:
The immediate effect of the neurotoxin on the postsynaptic neuron is to inhibit control over ion concentrations across the cell membrane. The neurotoxin blocks nervous transmission at synapses which prevents the vesicles containing the neurotransmitter from fusing with the presynaptic membrane so the information does not transfer from one neuron to another and as a result the body is present at constant relaxation mode. The membrane potential of postsynaptic neuron will decrease due to neurotoxin.

Explanation:
Explain why an mRNA transcribed from the template strand of the SIRT3 gene in normal stomach ( NS ) cells is translated to produce a SIRT3 protein of correct sequence, but if an mRNA were transcribed from the nontemplate strand of the SIRT3 gene in these cells, it would not produce a SIRT3 protein of correct sequence.
Answer:
Explanation:
The double-stranded DNA molecule has the potential to store genetic information in either strand, although in most organisms only one strand is used to encode any particular gene.
The template strand is the non-coding strand. The coding strand of DNA is the non-template (mRNA-like) strand (see attachment).
Thus, genetic information is expressed by transcription of the non-coding (template) strand of DNA, which produces an mRNA molecule that has the same sequence as the coding strand of DNA. Therefore, if a mRNA is transcribed from the non-template strand, the genetic information will not be contained in that strand and it would not produce a correct protein.

Why is it possible to do the following party tricks without cheating?
A. Stand with back and heels touching a wall and bend forward from the hips to touch the floor. Return to the upright position without flling or moving the root.
B. Stand facing the edge of an open door with nose and abdomen touching the edge, the feetstraddling the door, and the hands to the sides. Attempt to rise up on the toes.Observe what body motions occur to keep the center of gravity within the base of support whenthese activities are performed without the impediments.
Answer:
When the body is supported by a wall then it can move in a position counter gravity. The gravity tries to pull the body down and the body responds to it with a slight delay because of wall support.
Explanation:
The body is lifted in upright position with the help of feet. The body rises but after few minutes the gravitational force creates pressure on the body and the body comes down to a natural state. Similarly if the open door is used to perform counter gravity activities then the body will stay for a lesser period in a state because of opened door instead of firm wall support.

Explanation:
You plan to clone a guide RNA sequence into the pML104 plasmid because you want to engineer the construct in bacteria and later express it in yeast. Unfortunately, your lab does not have any available pML104. Your friend in the lab next door lets you borrow a related plasmid pML107, and you quickly start your experiment. Will it work? Briefly explain.
Answer:
Yes, the experiment will work.
Explanation:
The reason behind this is that plasmids are well known to be DNA vector carriers. These plasmids have the ability to bring about changes in DNA fragments into various microorganisms and reveal them. The two plasmids compose of the same genomic marker such as the antibiotic resistance gene found in URA3. However, plasmids are most commonly found in bacteria, but also in eukaryotic cells. Oftentimes, the gene composition in the plasmids enhances the bacteria with a vantage edge such as antibiotic resistance.
Hence, it is obvious that in both, the molecular regulation in terms of expression of genes is alike in properties. Similarly, the numbers of copies and molecular weight are also the same.
We can thereby conclude that, provided that there is a proper restriction site, another host that is up to standard for plasmid can be replaced for each other.
Membrane potential is present only in nerve cells.

During a 6 month period, 239 cases of pneumonia occurred in a town of 300 people. A clinical case was defined a fever >102oF lasting >2 days with three or more symptoms (i.e. chills, sweats, severe headache, cough, aching muscles/joints, fatigue, or felling ill). A laboratory-confimed case was defined as a positive result for antibodies against Coxiella burnetii. Before the outbreak, 2000 sheep were kept northwest of the town. Of the sheep tested from the flock, 15 were positive for C. burnetii antibodies. Wind blew from the northwest and rainfall was 0.5 cm compared with 7-10 cm during each of the previous three years.
Required:
a. What is the significance of the rainfall?
b. The etiologic agent of the disease is:______
c. This is an example of:_______
Answer:
a. What is the significance of the rainfall? These bacteria resist desiccation, and its dispersion is favored by winds. A decrease in rainfall means a dryer environment, which the bacteria can resist and makes it easier for the cell to be carried somewhere else by winds.
b. The etiologic agent of the disease is Coxiella burnetii
c. This is an example of a zoonosis
Explanation:
Q fiber Pneumonia is a zoonosis world-widely distributed and of global importance, which etiologic agent is Coxiella bunetti.
Zoonosis: Referred to as the infectious diseases that are naturally transmitted from animals to human beings. Among zoonotic pathogens, there are bacteria, viruses, or parasites. They propagate by direct contact, water, and wind, among others. These diseases represent a global importance problem due to the close ties with animals. Zoonotic diseases increase even more as human being keeps dispersing and invading natural wild environments to raise cattle and farm, among other activities. The etiologic agent is the element that propitiates the origin and evolution of a disease. Many bacteria and viruses might be considered to be one of the most common etiological agents.Populations in contact with goats, sheep, and cattle, use to have a positive result for antibodies against Coxiella burnetii. This bacteria is transmitted to humans orally and by inhalation. The microorganisms resist extreme conditions and are highly infectious. The inhalation of only one cell can produce an important infection in the host. It resists desiccation and any other environmental degradation. They can persist for several months and be transported by winds to farther places. This makes it even more difficult to determine the epidemiologic origin.
in what ways can overpopulation be beneficial to differential reproductive success?
Answer:
Differential reproduction is called the one that occurs as a result of the differences between the individuals that make up a society or sample, where it is those with comparative advantages who manage to reproduce, while those who do not have said advantages tend to die out. It is, in short, a practical application of Charles Darwin's theory of natural selection.
Thus, if there is an overpopulation of a certain species, a series of effects will occur (such as the scarcity of resources, the lack of living space, etc.) that will tend to gradually decrease the population to return to an ideal number of individuals. In this aspect, differential reproduction will be applied, being able to reproduce those that have comparative advantages over the rest, which will inevitably become extinct.

How do you think an environment and weather of a country can affect the population and people of a region
Answer:
Greatly affect the population.
Explanation:
Environment and weather of a country greatly affect the population and people of a region because good environment with all resources and suitable weather attract people of other regions toward itself. If the location has plenty of water, vegetation, flat geography and food etc, the people settled in this location and increase occur in population whereas if the area doesn't have any natural resources so people migrate from that area.
How much energy is gained during melting
Answer:
Explanation:
During melting, energy goes exclusively to changing the phase of a substance; it does not go into changing the temperature of a substance. Hence melting is an isothermal process because a substance stays at the same temperature.
A guinea pig with giant muscles is bred with a guinea pig with regular muscles. If muscle size in guinea pigs is INCOMPLETE dominance would these guinea pigs be able to produce a weak muscle guinea pig?
Answer:
Yes, they would be able to produce weak muscled guinea pigs
Please see details below
Explanation:
This question involves a single gene coding for muscle size in guinea pigs. The allele for giant muscles (G) is incompletely dominant over the allele for regular muscles (R). This means that a third intermediate phenotype (weak muscles) is produced in a heterozygous state.
According to this question, a guinea pig with giant muscles (GG) is bred with a guinea pig with regular muscles (RR). The following gametes will be produced by each parent:
GG - G and G
RR - R and R
Using these gametes in a punnet square (see attached image), the following proportions of offsprings will be produced:
GR, GR, GR, and GR
This shows that all the offsprings (100%) have weak muscles, hence, YES is the answer to this question.

Explanation:
The measured distance between genes D and E in a two point test cross is 50 map units. What could this mean in physical terms
Answer:
Genes that express 50% of recombination frequency or more are not linked genes. They might be in different chromosomes or located in the same one, but too far from each other.
Explanation:
Genes are physically located in chromosomes. Many genes segregate independently after crossing-over because they are located far away from each other. But some other genes are too close, and they do not segregate independently. These are the linked genes that do not exhibit an independent distribution, and they inherit together more frequently.
We need to know that 1% of recombination frequency = 1 map unit = 1cm. And that the maximum recombination frequency is always 50%.
When the recombination frequency is inferior to 50%, genes are linked. If it is equal or superior, they are not linked. Genes are located far enough from each other to assort independently.
Genes that express 50% of recombination frequency or more are not linked genes. They might be in different chromosomes or located in the same one, but too far from each other.
