Over the years, a Mexican wolf population in an area of Arizona became severely depleted. The U. S. Fish and Wildlife Service put in place a program to breed wolves and release them into the wild. A survey of the Mexican wolf population since the program’s introduction in 1998 is shown (see picture). Which statement best describes the recovery of the Mexican wolf population?

A. It is experiencing logistic growth because the rate of population growth increases without slowing.

B. It is experiencing logistic growth because the rate of population growth increases but slows with time.

C. It is experiencing exponential growth because the rate of population growth increases without slowing.

D. It is experiencing exponential growth because the rate of population growth increases but slows with time.

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.

Chinese privet is a plant that is native to china. over 150 years ago, chinese privet was introduced to the united states as a fast-growing shrub that serves as an excellent privacy hedge. with no natural herbivore, chinese privet quickly established itself and spread in natural areas throughout the southeast and eastern seaboard of the united states. its dominance in these areas has jeopardized the survival of native plant species. chinese privet provides evidence that introducing non-native organisms can cause environmental damage integrated pest management strategies will not decrease chinese privet populations american gardeners can easily control the spread of chinese privet non-native plant species have type i survivorship curves
