Which series of labels correctly identifies the indicated structures of this sketch of a cell under a microscope? if you need the answers it will take a while.

A: The right answer is Vacuole

Vacuoles are organelles present in plant cells.  It is a large single structure, of variable shape according to the cells, delimited by a lipid membrane called tonoplast.

The vacuoles allow the storage of water, ions, sugars, ... and by magnifying, play an important role in the growth of the plant.

B: The right answer is Mitochondria

Mitochondria are organelles present in eukaryoptic cells. The mitochondrion is composed of a double membrane, the inner membrane being folded into mitochondrial ridges.

Mitochondria are the organelles that produce the energy of the cell. The mitochondria thus have a role of power station for the cell. They are the ones who perform cellular respiration.

C: The right answer is Cell membrane (the inside layer)

All cells (prokaryotic and eukaryotic) are separated from their environment by a palsmic membrane.

The plasma membrane is the line of demarcation between the cell and its environment (= envelope of the cell).

It determines what goes into the cell and what comes out of it. Like all biological membranes, the plasma membrane has a selective permeability, that is to say it is allowed to pass through certain substances more easily than others.

The plasma membrane consists of a double lipid layer in which proteins are inserted.

D: The right answer is Chloroplast

Chloroplasts are important organelles specific to plant cells. Chloroplasts appear green ... They contain chlorophyll, a pigment that captures solar energy.

Choroplasts perform photosynthesis, that is, they absorb sunlight and use it for the manufacture (synthesis) of organic compounds from carbon dioxide and water.

E: The right answer is Lysosome

The lysosome is a small spherical structure (a vesicle) delimited by a lipid membrane located in the cytoplasm of eukaryotic cells. The membrane contains ion channels (proton pumps) that allow the active entry of H + ions, in order to maintain an acid pH (between 3.5 and 5) within the lysosomal vesicle.

Lysosomes are organelles of eukaryotic cells that contain a mixture of digestive enzymes used to degrade macromolecules.

Lysosomes are considered the "stomach" of the cell.

F: The right answer is Endoplasmic reticulum

The endoplasmic reticulum are organelles of eukaryotes that extend throughout the cytoplasm (like a labyrinth). These are organelles that produce proteins and play a vital role in the development of the other membranes of the cell.

relative dating involves things like higher layers are most recent than rocks lower in the sequence. this can be extended to the known sequence of fossils. rocks containing rabbit fossils are later than those containing dinosaur fossils.  

absolute dating methods mainly use radioactive elements that have known rates of decay and produce recognizable products. for example potassium 40 decays to produce argon. once a rock has solidified the argon is trapped. by measuring the argon and potassium0 you can get an accurate number for the age.  

some other methods are good for archaeological ages. dendrochronology involves recognizing the sequence of tree rings. the orientation of magnetized particles in baked clay can be used to date a fire.

hope this .. .
