Biomes are large-scale ecological communities characterized by distinct climate, vegetation, and animal life. The major biomes of the world include:
Tropical rainforest: Hot, humid climate with abundant rainfall; lush vegetation including ...tall trees, vines, and epiphytes; diverse animal life including primates, birds, and insects.
Temperate rainforest: Cooler, wetter climate than tropical rainforest; mixed forests of coniferous and broadleaf trees; diverse animal life including deer, bears, and salmon.
Temperate grassland: Semi-arid climate with seasonal rainfall; grasslands dominated by grasses and wildflowers; diverse animal life including bison, pronghorn, and prairie dogs.
Tundra: Cold, dry climate with long winters and short summers; treeless plains dominated by mosses, lichens, and dwarf shrubs; animal life including caribou, polar bears, and snowy owls.
Desert: Hot, dry climate with little rainfall; sparse vegetation including cacti, succulents, and thorny shrubs; animal life including snakes, lizards, and scorpions.

Learn all about Traits. which are characteristics that can be passed from one generation to the next. Genes, which are found on chromosomes are responsible for traits.
Traits are characteristics or ...features that can be passed from one generation to next generation. Some examples include hair color how tall you are, skin color, or gender or maybe even the shape of the nose.
If you take a look at dogs it could be long tails vs short tails, long ears or short ears.
In genetics, traits are determined by your genes. genes are sections of DNA that carry the code for a characteristic. Genes are located on chromosomes, which are structures in the nucleus of cells. Each cell in the body contains two copies of each chromosome, one inherited from each parent.For each trait you have different forms of the same trait, which are called alleles.
Alleles are located at the same position on chromosomes and determine the physical expression of a trait. The physical expression of a trait is the phenotype[+] Показать больше

In this video, I go over how to factor using grouping. Grouping works best with four terms.
For example, it would work well with, 6x + 36xz - 7y - ...42yz
Follow these steps
Step 1. Group the first two terms together and the last two terms together. The second sign goes with the second group.
Step 2. Find the GCF of each group and divide each group by the GCF
Step 3. Write the GCF out front of each set from step 2
Step 4. Factor out the common BINOMIAL,and write the remaining terms as the 2nd factor.[+] Показать больше
