Half the number of chromosomes
Answer:
Explanation:
Chloroplasts work to convert light energy of the Sun into sugars that can be used by cells. It is like a solar panel that changes sunlight energy into electric energy. The entire process is called photosynthesis and it all depends on the little green chlorophyll molecules in each chloroplast.
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
Answer:
C. Diffusion and no energy needed.
Explanation:
A - Passive transport doesn't require energy.
B - Osmosis would be if the 25% H2O went into the 82%
D - Active transport doesn't apply because molecules aren't moving across into a higher concentration.
Diffusion is when parts of the 82% go into the 25%.
