A prokaryotic cell is a cell without a nucleus (there's more to it, though).

Let's start from the bottom.

Strawberry plant: Plant cells are eukaryotic (cells have nucleus).
Hippopotamus: Animal cells are eukaryotic (cells have nucleus).
Paramecium: That's an animal, and animal cells are eukaryotic (cells have nucleus).
Bacterium: Perfect! Bacterium are prokaryotes! (cells don't have nucleus).

Your answer is bacterium.

Have an awesome day! :)

What mass of calcium hydroxide is formed when 10.0g of calcium oxide reacts with 10.0g of water?
nexus9112 [7]

The mass of calcium hydroxide that is formed when 10.0 g of CaO reacts with  10.0 g of water is 13.024 grams


calculation

from the equation

CaO + H2O → Ca(OH)2,

 1 moles of CaO reacted with 1 moles of H2O to form 1 moles of Ca(OH)2

find the moles of each reactant

moles=mass/molar mass

moles of CaO= 10 g/56 g/mol=0.179 moles

moles of H2O = 10 g/18 g/mol 0.556  moles

CaO is the limiting reagent  therefore by use of mole ratio of CaO:Ca(OH)2 which is 1:1 moles of Ca(OH)2 is = 0.179 moles

mass= moles x molar mass

= 0.176 moles x  74 g/mol = 13.024  grams

A sample of strontium bicarbonate weighs 5.0020 mg. How many oxygen atoms are in the sample? I have the answer, but don't unders
hodyreva [135]

There are 14.4 * 10^18 oxygen atoms in 5.0020 mg of  strontium bicarbonate.

Mass of strontium bicarbonate Sr(HCO3)2 = 5.0020 mg

Molar mass of strontium bicarbonate Sr(HCO3)2 = 209.6537 g/mol

Number of moles of strontium bicarbonate Sr(HCO3)2 = 5.0020 * 10^-3g/209.6537 g/mol

= 2.3858 * 10^-5 moles

Given that we have 6 oxygen atoms per molecule of Sr(HCO3)2, the total number of oxygen atoms in Sr(HCO3)2 becomes;

2.3858 * 10^-5 moles * 6.02 * 10^23 = 14.4 * 10^18 oxygen atoms

Which type of telescope would perform better on a mountaintop than at a lower elevation?
marishachu [46]

when an optical telescope located on the ground is used to view the sky the image has to surpass through the earth's atmosphere which is polluted. so the resolution wont be clear. When viewed on a mountain top both optical and infrared telescopes would perform better as the air above the atmosphere is less depth and cleaner.

Which statement best explains why gneiss is composed of layers but there are no layers in granite?
Mandarinka [93]

Gneiss is a sedimentary rock and granite is a metamorphic rock.

<h3>What are rocks?</h3>

Rocks are geological hard materials that are made up of various types which include:

  • Sedimentary rocks: These are rocks that made up of various layers formed from sediments. Example is the gnesis.

  • Metamorphic rocks: These are rocks that are form from pre existing rocks that undergoes some transformation. Example is granite

Therefore, Gneiss is a sedimentary rock and granite is a metamorphic rock.
