pancreas

Explanation:

In addition to the GI tract, there are digestion accessory organs (salivary glands, pancreas, gallbladder, and liver) that play an integral role in digestion. The accessory organs do not come directly in contact with food or digestive content.

The nurse should assure the patient that black tongue is an expected side effect of taking that particular drug. The active ingredient in the drug contain bismuth. The tongue and the alimentary canal of humans contain trace amount of sulphur, when bismuth comes in contact with this sulphur, bismuth-sulphide will be formed. Bismuth-sulphide is an harmless by product, thus, the tongue discoloration observed in the patient is harmless.<span />

What is the main difference between renewable and nonrenewable resources

Julli [10]

<span>The main difference of renewable and non-renewable resources lies in the capacity of the environment to replenish itself. Renewable resources are resources that can be easily replenished by the environment over a short period of time, while non-renewable resources take more time. <span>

Examples of renewable resources are solar energy, harnessing the sun's power that shines day to day. Wind energy that exists naturally is also a renewable source. Geothermal energy, heat coming from the center of the Earth, and Biofuels, fuels made from living organisms, are all renewable energy.

<span>Non-renewable energy resources are the fuels we use in our cars, minerals from the soil, coal, among others are supplies that also come from Earth. These are all materials that might take a long time (probably millions of years) to be fully restored. </span>

There are 258 g of MgCl2/liter. What is the molarity of the solution?

Zolol [24]

Taking into account the definition of molarity, the molarity of the solution is 2.7098 moles of MgCl₂/liter.

<h3>Definition of molarity</h3>

Molarity is a measure of the concentration of a solute in a solution and indicates the number of moles of solute that are dissolved in a given volume.

The molarity of a solution is calculated by dividing the moles of solute by the volume of the solution:

molarity= number of moles÷ volume

<h3>Molarity of the solution in this case</h3>

In this case, you know that the molar mass of MgCl₂ is 95.21 g/mole [molar mass is the amount of mass that a substance contains in one mole.]

You can apply the following rule of three: If by definition of molar mass 95.21 grams are contained in 1 mole, 258 grams are contained in how many moles?

amount of moles= (258 grams× 1 mole)÷ 95.21 grams

<u><em>amount of moles= 2.7098 moles</em></u>

Replacing in the definition of molarity:

258 g of MgCl₂/liter= <u><em>2.7098 moles of MgCl₂/liter</em></u>

<em />

Finally, the molarity of the solution is 2.7098 moles of MgCl₂/liter.

In the African savanna, more wildebeests are born than the environment can support. Which is most likely to happen over a period

Maurinko [17]

Answer:

Eventually, the environment will be unable to support the production of wildebeests, this will cause there to be a loss of vegitation that then causes a food shortage, and then the wildebeests will starve.

Explanation:

It's a very unhappy process, but those herds who don't migrate to another pasture will starve and die. The death will depopulate the savanna and give the fields some time for regrowth and the cycle will begin again.

Hope this helps! :)

Explain how bacterial cloning can help increasing the amount of DNA (DNA amplification) and when it is implemented in science or

Nezavi [6.7K]

Answer:

The process of gene cloning involve multiple steps. It involves many enzymes, bacterial cell, vector to produced an amplified number of cell and hence product.

The gene of interest is find and then it is carried into the bacterial cell by the help of vector.

The vector is then carried to get incorporated into the bacterial cell. In this way the bacterial cell starts replicating and the and the desired product is produced in high amount.
