Big Idea 1-34

34) Orders- animal classes are further divided into orders. For example the mammal class has the rodent is is the order to which rabbits and mice belong to, but they are part of the mammalian class and Chordata phylum. Snakes and lizards belong to the Squamata order, but they are part of the reptile class and Chordata phylum. Tortoises belong to the testudines order, but are part of the reptile class and Chordata phylum.


Big Idea 1-7

7) Annelids- is a phylum of  invertebrates with segmented bodies that have circular shapes and reproduce sexually. Examples are earthworms, marine worms, and leeches. The picture is of some worms that are about to be used as food. They have pretty round bodies so I'm guessing they're Annelids. 

Big Idea 3-17

17) Pollinator- is an organism, like insects or birds, that help plants with flowers or seeds pollinate. When they eat a seed or flower they spread the plants pollen to its flowers or to other places on the ground so more of a plant can grow. Conures are birds that when they eat in the wild, distribute seeds and help pollinate flowers. Bees are other well-known pollinators. 

Big Idea 4-1

1) Altruistic Behavior- is behavior in which an individual helps another, but suffers from it. Dogs are animals that show altruistic behavior. When their children or master is in danger they will become very protective and can fight for them, even if they get hurt. Humans and many other animals show altruistic behavior, especially when it concerns their own blood.

Big Idea 3-6

6) Haploid- an organism or cell that only has one set of chromosomes. Some organisms like bacteria are always haploid. Other organisms like humans, plants, and other sexually reproducing organisms have cells that are haploid, but are mainly diploid organisms. The picture above is of a palm tree. Palm trees have cells that are haploid meant for reproduction, just like humans have haploid gametes.

Big Idea 2-2

2) Anabolic- when energy is required for a reaction to occur. Anabolic reactions involve building something rather than breaking something down and require an input of energy. Stacking blocks represents anabolic reactions because no energy is being released. I have to use and input energy to stack the blocks.
