The object will weigh less on planet a than b because the pull of gravity isn’t as strong

Explanation:

Weight is defined as the force that the gravity exerts on an object due to its mass. So higher the gravity higher the weight and lower the gravity lower the  weight. The object on planet 'a' that has a force of gravity that is weaker than that of the planet 'b' will have less weight than the object on planet 'b'.

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.

If a lipid bilayer is at least 108 times less permeable to K ions than it is to water, how do the K ions that are needed for man
valina [46]

Answer:

Explanation:

If the lipid bilayer is at least 108 times less permeable to K ions than it is to water, then a way that this much needed ions can get into the cell is through ion channels.

Ion channels are memberane proteins that form pores and they also span across the cell membrane allowing ions to pass through these pores. They act as a passage through which charged ions can pass through. There are three main type: voltage-gated, extracellular ligand-gated, and intracellular ligand-gated ion channels.

How does a virus enter its host cell? PLZ HELP!!
DiKsa [7]

Answer:

Virus enters into the host cell through a process called endocytosis.

Explanation:

Endocytosis is a process in which molecule enters into the cell through cell membrane. Virus also enter into the host cell through this process. After entering, the virus starts replication and grow in numbers inside the host cell and take nutrients from it which is used in the process of reproduction. When virus population increases, it cause infection to the neighboring cells.
