The two algae seen here are classified as green algae. That means they make their own food by photosynthesis. The algae on the left is one-celled, or unicellular. The algae on the right is many-celled, or multicellular. How are these two types of algae different?
Question 5 options:

Only the the multicellular algae contains a chloroplast.

They are different only in how many cells make up each algae.

Only the multicellular algae has chlorophyll for photosynthesis.

The multicellular algae cel has many more parts than the unicellular algae.

If 10.g of agno3 is available, what volume of 0.25 m agno3 can be prepared

1. suppose a reaction mixture, when diluted with water, afforded 300 ml of an aqueous solution of 30 g of the reaction product malononitrile [ch2(cn)2], which is to be isolated by extraction with ether. the solubility of malononitrile in ether at room temperature is 20.0 g/100 ml, and in water is 13.3 g/100 ml. what weight of malononitrile would be recovered by extraction with (a) three 100-ml portions of ether and (b) one 300-ml portion of ether? suggestion: for each extraction, let x equal the weight extracted into the ether layer. in part (a), the concentration in the ether layer is x/100 and in the water layer is (30 x)/300; the ratio of these quantities is equal to k 20/13.3.
