Answer:

C.flagellum, lysosome

Explanation:

Flagellum and lysosome are the most appropriate structures for providing positive identification of an animal cell under a microscope.

Flagellum are thin filaments, formed by microtubules in their central portion, that allow the cell to swim by liquid means. Usually a flagellate cell has only one flagellum, which can average 200 µm in length and 0.2 µm in diameter. Flagellum are structures located in some specific cell types, which would help to identify a cell.

Lysosomes are organelles present in the cytoplasm of the vast majority of eukaryotic cells, which facilitates their identification. Inside the lysosomes we can find a lot of digestive enzymes.

I would say C.flagellum,lysosome  because I took the test tell me if wrong!

<span> We look for evidence. There are numerous natural phenomenon that we can't observe happening in real-time because they happen over large time scales, or large spatial scales. But we can observe the effects of these phenomenon and make predictions about what other effects we should see. </span>

Are these statements true or false? 1. Two sigma bonds comprise a double bond. 2. A triple bond consists of one pi bond and two
Bond [772]

Answer:

1) False

2) False

3) True

4) True

5) False

Explanation:

1. Two sigma bonds comprise a double bond: False

Two sigma bonds are not possible between two atoms . There will always be one pi bond or two bonds with one sigma bond

2. A triple bond consists of one pi bond and two sigma bonds.

Two sigma bonds are not possible between two atoms . There will always be one pi bond or two bonds with one sigma bond

3. Bonds formed from atomic s orbitals are always sigma bonds.  True

There is always an head to head overlapping possible with s orbital

4. A pi bond restricts rotation about the sigma-bond axis.

True.

5. A pi bond consists of two pairs of electrons.

False

Each bond can have one pair of electrons

Solid calcium carbonate decomposes to produce solid calcium oxide and carbon dioxide gas. Express your answer as a chemical equa
Gwar [14]

Answer:

CaCO_3(s)\rightarrow CaO(s)+CO_2(g)

Explanation:

Hello!

In this case, when solid calcium carbonate, CaCO3 (s), is decomposed by the action of thermal energy (heat), solid calcium oxide, CaO (s) and carbon dioxide gas, CO2 (g) are yielded via the following reaction:

CaCO_3\rightarrow CaO+CO_2

However, since calcium carbonate is solid as well as calcium oxide and carbon dioxide is given off as a gas, we write:

CaCO_3(s)\rightarrow CaO(s)+CO_2(g)

Which also balanced.

Best regards!

calculate the molar mass of a gas if 3.30 grams of the has occupies 660 ml at 735mmHg and 27 degrees C
AnnZ [28]
Use the ideal gas law PV = nRT and manipulate it to solve for n. PV/RT = n. Convert to SI units: 660ml -> 0.660 L 27 degrees -> 300 K Leave Pressure as is Use 62.36368 for R becuase you are using mmHg for Pressure. Now plug into the equation to get about 0.025928 mols. Divide the 3.30 grams by the mols to get about 127 g/mol.
