Pseudo vacuoles are not true organelles since they are just air bubbles which do not possess tonoplast and cell sap like real vacuoles. But they do help by increasing buoyancy of cells.

1 )Which of the following is a possible formula unit? PbO Li2B Al2Pb3 ClO

Nataly_w [17]

1. PbO is a possible formula units, since O has charge of 2- and Pb can have a charge of 2+ or 4+, if it uses the 2+ ion, the charges will balance out to form PbO. Li+ and B(3-) would have Li3B, Al(3+) and Pb(2+) are both positive charges and would not balance out, Cl- and O(2-) are both negative charges and would not balance out.

2. Iodine is a halogen, so it has a charge of -1. Calcium is an alkaline earth metal in Group 2, so it has a charge of 2+. Therefore, if they were to form a formula unit, the resultant would be CaI2 (2 iodine atoms of 1- charge are needed to balance out the 2+ charge on the calcium atom).

3. Strontium is an alkaline earth metal with a charge of 2+, while phosphorus has a charge of 3-. Therefore, to balance the charges out, we would need 3 atoms of strontium and 2 atoms of phosphorus. This would give the formula unit of Sr3P2.

Please help will do anything! Which of the following can be determined by this diagram?A.The energy of the mongoose is passed on

N76 [4]

Answer:

Explanation:

The arrows in this food web represent energy flow.

A. The energy of the mongoose is passed on to the hare.

The arrows points from the hare to the mongoose, which indicates the energy moving from hare to mongoose. Therefore,A is not correct.

B. The cheetah supplies energy to a variety of organisms.

There are no arrows that point from the cheetah to another organism. The arrows point from the other animals to the cheetah, indicating the cheetah is a top predator. So, B is not correct.

C. The energy of the acacia tree is passed on to the impala.

The acacia tree passes its energy onto termites, and these termites pass their energy onto the impala. Therefore, C is correct.

D. The aardvark, pangolin, and mongoose are all producers.

This is not true, because these are all animals. Producers are typically plants. Additionally, the producers are usually at the bottom of a food web.

So, C is the correct choice.

Are Consumers able to do photosynthesis? Why or why not?

Nata [24]

No. Photosynthesis is when a plant converts sunlight into food or glucose. Only producers are able to do this. Consumers have to consume food to have the energy to survive.

Hope this helped! Let me know if there is anything I need to clarify or explain more in depth
