Answer:

Real-time reverse-transcription polymerase chain reaction (rRT-PCR) assays are MOLECULAR tests that can be used to detect viral RNA in clinical samples. CDC’s current case definition for laboratory CONFIRMATION of MERS-CoV infection requires either a positive rRT-PCR result for at least two specific genomic targets, or a single positive TARGET with sequencing of a second target.

The success of rRT-PCR testing depends on SEVERAL factors, including the experience and expertise of laboratory personnel, laboratory environment (e.g., avoidance of contamination), and the type and condition of specimens being tested. For this rRT-PCR assay, CDC recommends COLLECTING multiple specimens, including lower (bronchalveolar lavage, sputum and tracheal aspirates) and upper (e.g., nasopharyngeal and oropharyngeal swabs) respiratory samples, serum, and stool specimens.

patient to be negative for active MERS-CoV infection following two consecutive negative rRT-PCR tests on all specimens.

Answer:

RADIATION is energy that comes from a SOURCE and TRAVELS through space and may be able to penetrate various materials. Light, radio, and MICROWAVES are types of radiation that are called non-ionizing.

Answer:

Virus isolation in cell cultures, immunofluorescence-based ASSAY and molecular techniques to determine nucleic acid, have all been used successfully to detect and identify the viruses. On the other hand, the most commonly used methods to quantify viruses can be subdivided into three broader categories – techniques measuring viral infectivity (viral plaque assay, TCID50 and immunofluorescence FOCI assay), those that examine viral nucleic acid and protein (qPCR, immunoblotting, immunoprecipitation, ELISA and hemagglutination assay) and those that rely on direct counting of physical viral PARTICLES (viral flow cytometry and transmission electron microscopy). Since each of these established methods has several limitations (Table 1), improved techniques of virus identification and quantification, such as mass spectrometry [5] and next-generation sequencing/metagenomics [6, 7], are explored to OVERCOME their limitations. Here we discuss some of the most common virus identification and quantification protocols, currently being used both in experimental and diagnostic virology.

PHYSICS

the emission of energy as electromagnetic waves or as moving subatomic particles, especially high-energy particles which CAUSE ionization.

2.

BIOLOGY

divergence out from a central point, in particular evolution from an ancestral animal or plant group into a VARIETY of new forms.

Xylem and Phloem conduct WATER across the PLANT. Stems stores food, water, and NUTRIENTS. Cells of a stem, meristems, produce new living tissues. UNDERGROUND stem, Aerial stem, and subaerial stem are three different types of Stem.

GIVEN:-

.

TO FIND:-

Pressure Applied on the Object.

FORMULAE USED:-

Here, Thrust = Force

Now,

.

So, The Pressure applied is 301.6Pa.

EXTRA INFORMATION:-

• Force Acting perpendicularly on the surface of the Object is called Thrust.

• Its SI unit is Newton.

• Thrust acting per unit area if the surface is known as Pressure

• Its SI unit is PASCAL

Answer:

An VEHICLE has a mass of 1500 KG. What must be the force between the vehicle and the road if the vehicle is to be stopped with a negative acceleration of 1.7 ms⁻²? ( Ans: 2550 N in a direction opposite to that of the vehicle)

EXPLANATION:

Answer:

Most atoms have three different subatomic particles inside them: protons, neutrons, and electrons. The protons and neutrons are packed together into the center of the atom (which is CALLED the NUCLEUS) and the electrons, which are very MUCH smaller, whizz around the outside. ... Most of an atom is empty SPACE.

Coffee OFTEN gets branded as an acidic drink, but in fact, coffee comes in at around a five on the pH scale, which is actually less acidic than drinks LIKE beer, orange juice, and even soda. So, when we talk about acid and coffee, most often, we are not actually TALKING about the pH level of the drink

Answer:

in cgs UNIT it is 2.5g/cm^3 and in si unit it is 2500 Kg/m^3

Explanation:

Given that,

MASS of an object=5000g

Volume OCCUPIED by an object=2000ml

we know that,

density=Mass/Volume

5000g/2000ml

2.5 or 5/2g/ml

in CGS unit=2.5/1 [1ml=1cm^3]

in si unit 2.5/1000/1/100*100*100

2.5/1000*100*100*100/1

2.5*1000/1

2500Kg/m^3

Explanation:

ANSWER:

the PERSON in train A is

• at REST with respect to another person in train A.because they both are in same train.
• at REST with respect to a person in train Because there is no change in speed and direction of trains so acceleration is constant.
• moving with CERTAIN velocity with respect to BRIDGE over which the train is running.because bridge is at rest but train is moving.

hope it helps...

Answer:

When the velocity of an object changes it is said to be accelerating. Acceleration is the rate of change of velocity with time. ... Acceleration occurs anytime an object's speed INCREASES or DECREASES, or it changes direction. MUCH LIKE velocity, there are two kinds of acceleration: average and instantaneous.

Answer:

The car has a LOWER mass, so it MUST have a higher velocity in order to have the same momentum as the truck. But SINCE kinetic ENERGY depends UPON the square of the velocity, the higher car velocity matters much more than the lower mass.

1.A ball of dough is rolled into a FLAT chapatti. NAME the FORCE exerted to change the shape of the dough.

2.A BATSMAN hitting a ball and its stops after moving som distance

Pls mark me the brainliest pls pls pls....

Instead of applying the FORCE at a single instant relatively speaking the ball transfers more of its energy to the glass whereas the bullet only transfers a small PORTION of its energy to the glass. The ball might ALSO flatten out to a small DEGREE making itself EVEN larger as it penetrates.

ANSWER:

MUSCULAR force

Hope this HELPS you..

Answer :

False

Explanation :

⇒ The force exerted by a charged BODY on another body is known as Electrostatic force or Coulomb force.

⇒ GRAVITATIONAL force operates among all objects in the universe.

⇒ Electrostatic force operates among charged particles.

⇒ The magnitude of electrostatic force b/w two point charges is directly proportional to the PRODUCT of charges and inversely proportional to the square of the DISTANCE b/w them. This is known as Coulomb's law also known as inverse square law.

⇒ Coulomb force and gravitational force follow the same inverse-square law. But gravitational force is always attractive, while Coulomb force can be bot attractive and repulsive, allowing possibility of cancellation of electric forces.

⇒ The law of gravitation is universally valid. It applies to small objects on the earth, planets in the solar SYSTEM and to galaxies.
