Answer – Absolute Dating

In order to determine the absolute age (otherwise called the actual age) of a rock layer, Geologists make use of a technique known as absolute dating. This technique is performed by assessing the nuclear decay of radioactive isotopes, a phenomenon that behaves in a clock-like manner.

A student was asked to compare a cell to a typical home. In this analogy, the cell mitochondria are like the (floor,furnace,or r
sdas [7]

Answer:

um...

If A Plant Cell Were A House...

Cytoplasm

Vacuole

The Cytoplasm

would be the carpeting. The Cytoplasm is the goo that all the organelles reside in, and all the furniture and stuff in the house kind of sit there in the carpeting.

The vacuole would

be the closets and pantries. The vacuole holds random things that the cell needs, and closets and pantries can hold anything you feel like putting in them, like food or clothes.

Lysosome

Mitochondrion

The mitochondrion would be the kitchen. It produces energy for the cell to use, and the kitchen produces food, energy for humans.

Nucleus

Endoplasmic Reticulum

Rough

The nucleus would be my mom. The nucleus controls the cell, and my mom controls my house.

Ribosomes

The Smooth ER would be just plain hallways. The ER is a vast network of tubing that things the cell needs travel down.

The Rough ER would be hallways filled with cattle. This wouldn't be a very good example, because it isn't a very vast network. A lot of people travel down them, though! The Rough ER is like smooth, except with ribosomes.

If you had a herd of cattle in your yard, it would be them. If not, just the kitchen, like the Mitochondrion. Ribosomes synthesize proteins, and cattle make milk, which is full of protein. Also, in the kitchen you can make proteins with different types of dairy, like cheese or milk.

Smooth

Lysosome

Golgi (apparatus)

The Lysosome would be the trashcans, the recycle, and the compost. The Lysosome kills bacteria and holds it in plus other waste, and we dispose of our waste by putting it in one of the above options.

The Golgi (apparatus) would be my dad. The Golgi sorts and packages macromolecules to get them ready to transport. My dad does the same sort of thing, he's in charge of kind of organizing/sorting things around the house.

Cell Membrane

The Cell Membrane would be

the doors and the screens (on the windows). The cell membrane is a semi-permeable barrier, meaning that some things can get through and some can't. For example, only people who have the right key can open the door. Also, with the screens, air can get in, but flies and bees can't.

Chloroplast

Cell Wall

The Chloroplasts would be solar panels, if you had any, or houseplants if not. The Chloroplasts convert sunlight into energy, and both houseplants and solar panels do this same job.

If a cell were a house,

the walls, floors, and ceiling would be the cell wall because they keep everything in the house inside, just like the cell wall keeps all the organelles inside the cell.

The muscles in the leg are considered long muscles. As the muscles in the leg contract and relax they work to provide movement.
Maurinko [17]

Answer: if the upper leg muscles were damaged, (You would not be able to extend the leg straight).

Explanation:

The upper leg muscles, which can also be called the thigh, are made up of three sets of muscles which include:

--> the hamstring muscles: These are located at the BACK of the thigh. They are made up of three long muscles which includes the semimembranous muscle, the semitendinosus muscle, and the biceps femoris muscle.

--> the quadriceps muscles: They are located at the FRONT of the thigh. They consists of four individual muscles which includes the three vastus muscles and the rectus femoris.

--> the adductor muscles: They are located at the medial compartment of the thigh and is consist of the following muscles: gracilis, obturator externus, adductor brevis, adductor longus and adductor magnus.

The quadriceps, hamstrings and adductor muscles work together to straighten (extend) and bend (flex) the leg. Therefore when there is damage to the upper leg muscles, you would not be able to extend the leg straight.
