Answer:
9- C
cellulose strengthens the cell walls present in a plant
enzymes and antibodies are made of proteins
water is the universal solvent.
10- C, all 3
1- cytoplasm contains about 85% of water, which helps in movement within the cells.
2- urine contains 95% of water, and it dissolve urea and salts in it.
3- plasma contains 90% of water, so we can say that water allows transportation of substances in the blood.
<h2>Gametophyte and Sporophyte Generations</h2>
Explanation:
- <em>The sexual stage, called the gametophyte generation,</em> produces gametes, or <em>sex cells, and the abiogenetic stage, or sporophyte age, </em>produces spores abiogenetically
- As far as chromosomes, the <em>gametophyte is haploid</em> (has a solitary arrangement of chromosomes), and the <em>sporophyte is diploid (has a double set)</em>
- All aquatic plants have alternation of generations. In mosses and their <em>family members (Bryophytes), the haploid gametophyte is the predominant age,</em> and the diploid sporophytes are sporangium-bearing stalks developing from the gametophytes

There are two things that occur in aquarium ammonia chemisty. 1. the build up of natural ammonia and nitrate in the water. 2. displacement of oxygen in the water caused by the ammonia. This is a very real threat especially when you have a new tank that is still cycling or when the biological filter has been upset or removed.
Look for these main symptoms if you suspect ammonia poisoning in your fish tank:
-loss of appetite
-lethargic fish
-fish gasping for air/breath at the top of the water
-fish laying at the bottom of the tank
-red/purple gills
-red streaking on the fish's body
- fins becoming torn and jagged
-scales on fish falling off or turning black
