What is Darwin's hypothesis that the development of species is a slow?

Darwin's hypothesis that the development of species is a slow, gradual process The relationships among different orders of millipedes are shown in the cladogram. Based on this cladogram, which statement best describes relationships among millipede orders?

What are the major groups of plants?

The major plant groups include bryophytes (mosses), pteridophytes (ferns), gymnosperms (conifers), and angiosperms (flowering, seed-bearing plants). Mosses are short plants and their leaves are usually only one cell thick.

What is an organism's ability to survive and reproduce in its environment?

An organism's ability to survive and reproduce in its environment refers to its Fitness Two organisms that are closely related would have very similar DNA sequence Mutations are important because they bring about

Which study of early stages of development is one evidence of evolution?

The study of the early stages of development that is one evidence of evolution is: Embryology Superficially similar features molded by natural selection in very different species are classified as what kind of structures? analogous (SC.912.L.15.1) The scientific theory of evolution is supported by different types of evidence.

What are the four kingdoms of plants?

The kingdom Plantae consists of four major plant groups on land: bryophytes (mosses), pteridophytes (ferns), gymnosperms (cone-bearing plants), and angiosperms (flowering plants). Plants may be categorized as vascular or nonvascular. A vascular plant has tissues for transporting water or sap. Nonvascular plants do not.

What is the life of plants?

Plant life is diverse, adaptive, and environmentally successful. This means they exist in many of Earth's ecosystems. All plants are autotrophs, producing their own food through photosynthesis, which makes food using light, and thus plants provide food to an array of consumers and decomposers. The kingdom Plantae consists ...

What kingdom is phytoplankton in?

Although these phytoplankton technically fall under the kingdom Plantae , they are not part of the four major groups already discussed, which include only land plants. Although the life cycles of plant groups may seem different, they all have some characteristics in common.

How many species of angiosperms are there?

Angiosperms have more than 260,000 living species. Gymnosperms include the oldest (bristlecone pine), the tallest (redwoods), and the thickest (Montezuma bald cypress) living species. At the opposite end of the plant spectrum are green algae, some of which are single-celled.

What are the two types of organisms that produce seeds?

Gymnosperms and angiosperms produce seeds, while bryophytes and pteridophytes produce spores. Plants have varied, unique structures, yet all plants are eukaryotic organisms, meaning they have a cell nucleus and membrane-bound organelles. Plants exist in all types of ecosystems.

What is the hypothesis that evolution of a species occurs in periods of rapid change separated by periods of little or no change

The hypothesis that evolution of a species occurs in periods of rapid change separated by periods of little or no change is called. punctuated equilibrium. T15. The hypothesis that evolution of a species occurs gradually over time as a slow and constant process is known as. gradualism.

Where do brown creepers eat?

Brown creepers feed on insects found near the bottom of the tree trunk, while nuthatches feed on insects in the top part of the tree. The difference in foraging behavior most likely affects the nuthatches and brown creepers by —. reducing competition between the birds for resources.

Where do white cattails live?

Over time, the white cattail has established itself in the wetlands of Midwestern states . Favorable genes from parental generations provide advantageous characteristics to the hybrid species. In North American forests, two species of birds, nuthatches and brown creepers, forage on the same trees for insects.
