First of all, it makes algae grow, because pesticides and stuff provide too many nutrients. Algae needs a lot of oxygen and so the fish begin to die off because the algae is taking all the oxygen out of the lake. Next, it causes biodiversity to drop, meaning that species are beginning to get less varied. Water pollution harms the lakes and is a concern because the effects of it on species and the water will stay.
The left side of the heart collects oxygen-rich blood from the lungs and pumps it to the body. The left and right sides of the heart are divided by walls<span> called septums. There is an atrial septum that separates the right and left atriums, and a ventricular septum that separates the right and left ventricles.</span>
<span>The muscle cell would have more mitochondria than the other types of animals cells.</span>
Binary fission; It occurs when a prokaryote or a single celled eukaryote reproduces asexually and divides into two similar sized daughter cells rather than a bud or fragments, which is found in budding and fragmentation. <span />
A rain forest would have the most species diversity if you are talking about complex eukaryotic organisms (reptiles, mammals etc), though the polluted lake would have the most simple prokaryotic organisms ( bacteria, protists, fungi etc.)
