Today, only about 25% of the Earth is still in its natural, unaltered state. The rest of the terrestrial biosphere consists of human-altered biomes, called anthropogenic biomes or anthromes. The map shows the five main anthromes in the western United States. On this map, much of the land classified in the urban, or highly developed, anthrome is near the coast, while a large part of the wildlands is comprised of desert. What is one reason urban anthromes may be concentrated in coastal areas?
a
Coastal areas are less likely to have a variety of plants and animals than deserts.
b
Coastal areas are more likely to have large temperature fluctuations than deserts.
c
Coastal areas always experience natural disasters.
d
Coastal areas are more likely to have more available natural resources than deserts

The construction of phylogenetic trees is a mapping out the proposed divisions and common ancestors of all living species. traditionally, these trees have been built using morphological data, such as appearance and embryology. recently, it has been possible to construct these trees using molecular data. phylogenetic trees based on different types of information agree with each: that there is strong evidence of a real underlying common descent. this phylogenic tree is composed based on molecular data (rrna). what statements can we infer are true about the organisms throughout the tree? because the tree is rooted, all branches share a common ancestor. all organisms have some sort of cellular structure/organization. all eukaryotes evolved from bacteria. since the organisms contain rna, they share the same dna. if the organisms contain rna, the share the same four nitrogen bases.

Be in this im starting a with you so if you want you can get a partner for this. but basically im going to assign you guys a biome and you have to have a big sheet paper and you will turn it into 4 squares. the top right square is will be a drawing square for a drawing you will make of your biome. the top left square is about the biomes plants and drawings of them. the bottom left square is about the biomes animals. the bottem rights square is about the description of the biome. leave a comment or an answer and i will assign biomes. if your request one thats the one you get. send me a link to the project and i will grade ! im not a teacher btw.

In general, characteristics that an organism survive and reproduce become more common over time. what mechanism of evolution causes this?
