Maria claimed that she could not see through the safety goggles and wore them on top of her head rather than over her eyes. While pouring an unknown chemical into a beaker, she accidently splashed some of the chemical in her eyes. What should Maria immediately do next?

Answers

Answer:

She should immediately rinse or flush her eyes with water.

Explanation:

One of the most important precautionary measure to be taken when working with explosive chemicals in the laboratory is the use of safety goggles. However, in this case, Maria claimed that she could not see through the safety goggles and wore them on top of her head rather than over her eyes.

Maria accidentally splashed some chemicals into her eyes while trying to pour it into a beaker. The primary or initial response to this happening is to immediately FLUSH OR RINSE her eyes with water. This will flush away the chemical from her eyes before it can have its detrimental effect.

Answer:

proceed to the eye wash station, open her eyes, and rinse them for at least 15 minutes

describe the role of prothrombin in the blood clotting process

Answers

Answer:Prothrombin is transformed into thrombin by a clotting factor known as factor X or prothrombinase; thrombin then acts to transform fibrinogen, also present in plasma, into fibrin, which, in combination with platelets from the blood, forms a clot (a process called coagulation).

In the diagram of the DNA molecule below, match the correct term with the image (ignore the blank arrow).

Answers

Answer:

hope this help

Explanation:

Nucleic acids are made up of chains of many repeating units called nucleotides (see bottom left of Figure 1 below). The DNA molecule actually consists of two such chains that spiral around an imaginary axis to form a double helix (spiral.)  Nucleic acid molecules are incredibly complex, containing the code that guarantees the accurate ordering of the 20 amino acids in all proteins made by living cells.  Surprisingly though there are only a few different nucleotides: only four different nucleotide units comprise DNA, the nucleic acid of interest to the genealogist.  

 

 

This figure is a diagram of a short stretch of a DNA molecule which is unwound and flattened for clarity. The boxed area at the lower left encloses one nucleotide.  Each nucleotide is itself make of three subunits:

A five carbon sugar called deoxyribose (Labeled S)

A phosphate group (a phosphorous atom surrounded by four oxygen atoms.) (Labeled P)

And one of four nitrogen-containing molecules called nucleotides . (Labeled A, T, C, or G)

 

 

 

Alternating sugar and phosphate units form the two sides of a ladder-shaped arrangement with the rungs or steps each formed by a pair of nucleotide bases. Figure 2 below shows the structural formula of DNA in greater detail. The nitrogen bases are ring compounds with their carbon and nitrogen atoms arranged in single or double rings.  Only certain bases can pair together to form base pairs.  In DNA, Adenine (A) always pairs with thymine (T), and guanine (G) always pairs with cytosine (C).  

Notice that in the two figures above, the two strands of a DNA molecule are antiparallel, that is, they run in different directions. The side of the chain on the left begins with a free phosphate group at the top and ends with a sugar molecule at the bottom.  In contrast, the complementary chain on the right begins at the top with a sugar molecule and ends at the bottom with a phosphate group.  

Happily, it is not necessary to hold the details of DNA structure in your mind at all times!   As the sugar and phosphate sides of the molecule are constant they are frequently represented by parallel lines.  Even better, each of the nitrogen bases is conveniently represented by the first letter of its name.  These conventions allow the simplified representation of the molecule shown in the figure below

Or, even easier, a section of a DNA molecule is often abbreviated to show the bases of just one strand:

A T G G C T A C

Knowing the base pairing convention of A always pairing with T and G always pairing with C makes the complementary strand of the molecule understood.  It is this feature of complementary base pairing that insures an exact duplicate of each DNA molecule will be passed to its daughter cells when a cell divides.

15. Explain how each of the following creates electrical energy:
a.
Solar
Hydro
Tidal
Wind
OTEC
Biomass
Geothermal

Answers

Solar- technologies convert sunlight into electrical energy either through photovoltaic panels or through mirrors that concentrate solar radiation.

Hydro- a hydraulic turbine converts the energy of flowing water into mechanical energy. A hydroelectric generator converts this mechanical energy into electricity

Tidal- energy is a form of hydropower that works by harnessing the kinetic energy created from the rise and fall of ocean tides and currents, also called tidal flows, and turns into unusable electricity

Wind- turns the propeller like blades of a turbine around a rotor, which spins a generator, which creates electricity

OTEC- plants pump large quantities of deep cold seawater and surface seawater to run a power cycle and produce electricity

Biomass- is burned in a boiler to produce high-pressure steam. This steam flows over a series of turbine blades, causing them to rotate. The rotation of the turbine drives a generator, producing electricity

Geothermal- power plants use steam to produce electricity. The steam comes from reservoirs of hot water found a few miles or more below the earth’s surface. The steam rotates a turbine that activates a generator, which produces electricity

Compare and Contrasts Biotic Factors and Abiotic Factors. What are they?
How are the alike.
How are the different?

Answers

A biotic factor is a living thing that has an impact on another population of living things or on the environment. Abiotic factors do the same thing, but they are non-living. Together, biotic and abiotic factors make up an ecosystem. To survive, biotic factors need abiotic factors.
Biotic factors are living organisms that typically contribute in some way to their environment. Some examples of Biotic factors include plants, animals, cells and they are typically producers, consumers or decomposes. Unlike Biotic factors, Abiotic factors are the non-living part of an ecosystem. They are typically chemical or physical, some abiotic factors include water, sunlight, soil, and temperature. Both Biotic and Abiotic factors are required in an ecosystem to properly function.
