Yes start your paragraph by saying the vaccine is essential because….
It is essential simply because for one we need it… to summarize everything that has been stated so far yes I should be taking the vaccine as well as everyone else because I want to take precautions to stay safe… Thank you and have a wonderful day

You could have a paragraph on the history of them not only how they were developed but how the concept of using antibodies has been around for a very long time.
Another about the actual science behind the ones we use today - dead antigens, and how it activates T cells and memory B cells etc
Perhaps one about the risks and benefits? And go into specific actual case studies?

A patient comes to you with a "PUS" sample and asks you to isolate & identify the Staphylococcus aureus form this sample the
Irina-Kira [14]

Answer: Staphylococcus aureus can be isolated from the pus sample through the following steps:

--> Step 1: Describe the appearance of the specimen

--> Step 2: Examine the specimen microscopically

--> Step 3: Culture and report your observations.

--> Step 4: Biochemical testing

Explanation: Staphylococcus aureus are gram positive cocci bacteria that can be isolated from pus samples.Pus samples, which may come from wounds, abscess, burns or sinuses, are the type of samples which do not contain microorganisms and should not contain contaminants providing an aseptic collection technique and sterile container are used.

Staphylococcus aureus can be isolated from the pus sample through the following steps:

--> Step 1: White, yellow, brown, red, or black granules of varying size, shape, and consistency may be found in pus draining from

sinuses while describing the appearance of the pus sample.

--> Step 2: Here the specimen is examined microscopically after being stained with a staining technique called Gram staining. This step is done before culture to know the type of medium to use after gram positive cocci is microscopically seen.

--> Step 3: there are different cultures media that can be used to inoculate and culture a pus specimen. Since we are to isolate staphylococcus aureus, a selective and differential media known as Mannitol salt agar (MSA) is used. The presence of yellow colonies with yellow zone after incubation at 37°C indicate the presence of Staphylococcus aureus or species. There for the last confirmation test known as biochemical test is done.

--> Biochemical test: This is a chemical test that is done to identify a particular bacteria. For staphylococcus aureus, COAGULASE test is used to identify staphylococcus aureus which produces COAGULASE enzyme. A positive COAGULASE test is an indication of the presence of staphylococcus aureus as the bacterium isolate of the specimen.

In a college biology experiment, 50 mg of methane and 60 mg of sulfate are mixed in a closed container. What is the limiting rea
Amanda [17]

Answer:

CH₄ is the excess reagent and SO₄²⁻ is the limiting reagent.

0.040 g

Explanation:

Step 1: Write the balanced reaction for the methane anaerobic oxidation

CH₄ + SO₄²⁻ ⇒ S²⁻ + CO₂ + 2 H₂O

Step 2: Establish the theoretical mass ratio between the reactants

According to the balanced equation, the theoretical mass ratio of CH₄ to SO₄²⁻ is 16.04:96.06 = 0.1670:1

Step 3: Establish the experimental mass ratio between the reactants

50 mg (0.050 g) of CH₄ react with 60 mg (0.060 g) of SO₄²⁻. The experimental mass ratio of CH₄ to SO₄²⁻ is 0.050:0.060 = 0.83:1

Comparing both mass ratios, we can deduce that CH₄ is the excess reagent and SO₄²⁻ is the limiting reagent.

Step 4: Calculate the mass excess of CH₄

The mass of CH₄ that reacts with 0.060 g of SO₄²⁻ is:

0.060 g SO₄²⁻ 16.04 g CH₄/96.06 g SO₄²⁻ = 0.010 g CH₄

The mass excess of CH₄ is:

0.050 g - 0.010 g = 0.040 g

The great seal of the united states features an eagle clutching an olive branch in the talons of its right foot, symbolizing the
vovangra [49]

The power of peace is being seized grasping  in the talons of its other foot.

<h3>A shield, a scroll, an olive branch, or a phrase is what the eagle on the Great Seal is holding in his right talon?</h3>

In the artwork, an eagle holding the motto "E Pluribus Unum" on a scroll with an olive branch representing peace and thirteen arrows representing conflict are displayed in each of its claws. The year 1776 is written in Roman numerals at the foot of a thirteen-step pyramid on the reverse of the seal.

<h3>What does the eagle represent in the US coat of arms?</h3>

The Founding Fathers made the right choice when they designated the bald eagle as the country's emblem. The fierce woman and the great bird's proud independence effectively represents America's strength and freedom.
