Complete question: Analyzing Mannitol Salt Agar (MSA): An MSA plate was inoculated with an unknown Staphylococcus species. What can you conclude about this unknown organism?
A. It can ferment mannitol.
B. It produces acid during fermentation, leading to a lower pH in the medium.
C. It can tolerate higher salt concentrations.
D. It could be S. aureus.
E. All the above
Answer: The correct option is E ( all of the above)
Explanation:
Culture medium is a growth medium that is used in microbiology which permits the growth of microorganisms. It can be in a gel or liquid form. There are different types of culture medium which includes:
--> Differential medium
--> Selective medium
--> Enriched medium
Mannitol Salt Agar( MSA) is a type of selective culture media that is used in microbiology for the identification and isolation of staphylococcus species from biological samples. A typical MSA includes essential growth factors and trace nutrients such as nitrogen, vitamins, minerals and amino acids essential for growth. The medium contains sodium chloride( salt) with mannitol which is the fermentable carbohydrate source
Staphylococcus aureus organisms are capable of fermenting mannitol, produces acid during fermentation leading to a lower pH in the medium, and can tolerate higher salt concentrations. Therefore the unknown organism is POSITIVE to mannitol salt agar analysis. Thanks and I hope it helps!

animal cells have structures that perform specific functions in the cell. Mitochondria are oranelles that float within the cell. Because they produce most of the cell’s energy, mitochondria are nicknamed the “powerhouse of the cell”.
which of the following types of cells would have the greatest number of mitochondria?
skin cell
blood cell
muscle cell
fingernail cell
Answer:
skin cell because the skin is considered the largest part of the cell tissue based on order.

EXPLAIN 2 DIFFERENCES BETWEEN THE BREAD MAKING ANDALCOHOL PRODUCTION PROCESSES.
Answer:
Pastry dough is rolled out thinly and used as a base for baked products. Pastry is differentiated from bread by having a higher fat content, which contributes to a flaky or crumbly texture. ... On the other hand, overmixing results in long gluten strands that toughen the pastry.

A lamp that plugs into a wall socket draws energy which flows through a thin wire in the bulb causing it to glow. What energy transformation are taking place?
choices:
Chemical>light>electrical
Mechanical>sound>light
Thermal>solar>electrical
Electrical>thermal>light
Answer:
Electrical>thermal>light
Explanation:
Electrical energy refers to energy which is gotten from potential energy. This energy source could be a wall socket.
Thermal energy on the other hand refers to internal energy of a system where temperature is constant.
Light energy is made up of photons which transmits electromagnetic radiation which move in waves and become visible to human eye.
Therefore, the energy transformation taking place according to the question is option D.

Think and discuss:Suppose you are a farmer trying to grow plants in a greenhouse. Why would it be important to know what the limiting factor is
Answer:
Because limiting factors affect plant growth
Explanation:
A limiting factor is a condition that limits the population's growth in an ecosystem by slowing or stopping its growth. These factors are generated by the lack or excess of a particular resource. In plants, limiting factors include, among others, light, water, temperature, oxygen, food, (i.e., nutrients and minerals), space, etc. In this case, the farmer must know which greenhouse conditions are limiting factors in order to ensure the survival and optimal development of the plant population.

Which physical evidence supports the evolution of Earth due to chemical weathering? (10 points!)
a
Hammer shape of Bryce Canyon rocks
b
Red color of Bryce Canyon rocks
c
Streaks on the face of Wave Rock
d
Concave shape of Wave Rock
Answer: B
Explanation: It is believed that Thor's Hammer started out as a large plateau 40 to 60 million years ago and has slowly evolved through the natural processes of weathering and erosion to its current formation. The red coloring on the rock is due to oxidation, a form of chemical weathering.

Im 4 and my sis is 13. SHE told me she was on her period but then I told her there was this thing called subject and predicate and how she isnt supposed to have a period at the end of her statement because it wouldnt make any sense... and ya, it didnt go well cause' she put on a tantrum.
But the weird thing is that Google said this "Tantrums are most common between the ages of one and four, then decrease when children start school." SO HOW COME I DIDN"T HABE A TANTRUM!! life makes no sense.
P.S: I even saw mom buying DiApERS for her! Like I stopped my diapers and got potty trained about 1 or 2 months ago and IM 4yrs old. SHE IS 13.

Which process passes genetic material to offspring?
E. coli Is a species of bacteria that causes many different Infections in humans. Certain E. coli strains have developed resistance to antibiotics,
making Infections with these strains difficult to treat. How do bacteria such as E. coll, which reproduce asexually, galn new tralts such as
antibiotic resistance?
O A. by adapting to changes in environmental conditions without undergoing changes in their DNA
OB. by mutating their DNA in response to environmental conditions to gain beneficial traits
OC. by undergoing spontaneous mutations when they replicate, which increases genetic variation in a population
OD. by producing offspring with new gene assortments from genetic recombination, which increases diversity in a population
Answer:
The correct answer would be B
Explanation:
Antibiotic resistance in bacteria develops in response to the environment in which the bacteria survives.
The antimicrobial resistance trait is acquired by any species of bacteria through one of the two ways that are either by making changes in their DNA sequences or through horizontal gene transfer mechanisms.
In the given E. coli gained the trait to develop resistance against antibiotic by making changes in their DNA as once the gene is altered or mutated, the trait can be passed on to the offsprings.
Therefore, Option-B is the correct answer.
Answer:
B. By mutating their DNA in response to environmental conditions to gain beneficial traits
Explanation:
Through the process of natural selection, bacteria such as E coli can gain new traits that benefit them.
This can occur when a DNA mutation occurs, where the mutated gene is actually beneficial to respond to environmental conditions.
Then, these bacteria with the gene will survive and produce more offspring with the same gene. This is how E coli can develop antibiotic resistance.
So, B is the correct answer.

What kind of rock is shown in the picture ?
How do you know what type of rock it is ?
Answer:
Sedimentary
Because it is made is sediments
Explanation:
got it right , edge 2020
The picture shown here is of sedimentary rock. It is visible so because of the identification features of a rock as shown in the image.
What is the formation of rock making process ?The process is that the soil and the sand that gets accumulated and together with the mud gets collected in order to form a hard mass by the passing of time called as rock.
The kind of rock identification is done on the basis of rock identification aspects that are decided for each type of rock that has been kept under observation. In sedimentary rock, the grains and the displacement of rock grains together gives a larger or smaller appearances.
The types of layers and mud particles joined together along with the ripple marks that have been put together shows the marks on the rocks.

How did Claire's digestion reaction weights tell you that the problem was in her small intestine, and not in her stomach
Answer:
The reaction rate of the digestion helps in understanding which part of the digestive system having trouble in digestion especialy stomach and intenstine related.
It involves the fact that most of the enrgy or calories are get by the small intestine and also vitamins and minerals are absorbed by this part of the digestive system so if the small intestine is having problem the rate of digestion would be affected and and an individual could be malabosrbed.
If the problem lies in the stomach it might show some effects of a poor digestion, however the rate of digestion would be better than if the problem lies in the small intestine.
