well we finished the experiment today too, we wrote down results. essentially the plants that were watered grew many, large leaves, as opposed to pretty much none on the unwatered plants. also the ones that got more sunlight had bigger leaves.
after that we just did a bit of revision on DNA.
deoxyribonucleic acid, is composed of nucleotides. a nucleotide is composed of a sugar (deoxyribose) a nitrogen base (adenine, thymine, cytosine and guanine) and a phosphate that bonds the sugar to another sugar.
RNA is pretty much the same, but unlike DNA that is a double helix, RNA is a single strand, and it has uracil instead of thymine.
random note: humans have been around for like a million years, and cyanobacteria like dominiated for liek 2 billion years, dinosaurs for like 400 million.
mitosis produces 2 daughter cells taht are identical, and have a set of chromosomes each (46 for people) these are somatic cells.
the opposite of somatic cells are gametic cells, or gametes (sex cells) they only possess half the amount of chromosomes each (23) and they combine to create the offspring's genes and stuff. this is what causes variation, and hence, evolution.
