What action could be taken to help conserve the world's supply of copper?

Biology
1 answer:
AlladinOne [14]3 years ago
7 0

Answer:  This is a hard question because we need copper for just about anything.  Some people say that electric cars are better because the conserve fuel, but they have copper.  The source of all of our power (electricity) stems from copper.  Simply said, no matter what you do to conserve copper, you are still going to need it and use it.

Choose the CORRECT statement concerning the cell membrane lipid molecules
VashaNatasha [74]

Answer:

The correct statement concerning the cell membrane lipid molecules is that "energy is not expended during diffusion" (Option d)

Explanation:

Biological membranes are formed by two lipidic layers arranged with their hydrophilic polar heads facing the exterior and the interior of the cells, and their hydrophobic tails against each other. Membranes are fluid, which means that molecules that form it have the capability to move through it.  

Lipids can easily change places with other neighbor lipids by <u>lateral diffusion</u> in the same layer. This is passive diffusion, which means that it does not need energy to happen.

Lipids can also diffuse transversally to the other layer, but this kind of movement is not as easy as lateral diffusion.

There are also other lipidic movements as rotational diffusion that imply the rotation of the molecule.

Through this lipidic bilayer, there is also a passive transport of some particles from one side of the cell to the other which happens because of concentration differences.

Answer:

Figure 3

Explanation:

A mixture is a substance made up of two or more different kind of atoms arranged in such a way that they are not chemically linked or joined. This accounts for the reason a mixture can be separated easily. In the figures attached as an image in this question:

- Figure 1 represents an element because it is made up of only hydrogen atoms chemically bonded together to form a molecule.

- Figure 2 represents a compound because it contains hydrogen and carbon atoms chemically joined together.

- Figure 3 represents a MIXTURE because it contains the oxygen and carbon atoms, which are not chemically joined to one another. As seen in the image, the oxygen atoms are not joined to the carbon atoms.

- Figure 4 represents a compound because it contains oxygen and hydrogen atoms chemically bonded together.
