Timeline for the formation of the earth - including the arrival of terrestrial plants and animals
5) Place the following events on a rough timeline of the history of life on Earth (using the geological time line on the next page): radiation of the mammals, origin of flight in the insects, earliest fossils, formation of the oxygen rich atmosphere. origin of the Eukaryotes, invasion of land by tetrapods. invasion of land by plants, the largest mass extinction in the history of life on Earth
5. d) Both plants and animals originated in aquatic environments, and eventually evolved to live on land. Describe a common challenge that both plants and animals faced in the move from an aquatic to a terrestrial environment, and new traits or modifications of traits that facilitated the evolution onto land. (10 points)
what adaptations do non-vascular plants share with vascular plants that allow for a terrestrial existence?
Describe the differences and similarities in the gene families used by plants and animals to establish the body axis and to regulate gene expression of these gene sets. Drag the appropriate traits to their respective bins. Three respective bins: 1. Specific for plants. 2. Specific for animals 3. Common for plants and animals Traits are following: MADS-box proteins Three classes of homeotic genes (A, B, and C) Homeodomain-containing proteins Using regulatory genes encoding transcription factors Formation of organs is determined...
What key features help the terrestrial animals survive and reproduce on land? How?
19. Compare the osmoregulatory challenges faced by animals that live in different environments (terrestrial, freshwater, and saltwater) and briefly explain how animals deal with the challenges posed in each environment. detail
Good examples of the evolutionary mechanism of natural selection are common among plants and animals, including the human animal. Find an example of natural selection that is of interest to you from a scientific source on the internet and summarize it in your own words for your classmates in 1-2 paragraphs. Include in your summary a description of the species, its adaptation to environmental conditions, and how natural selection acts to shape the characteristics of the population. Then
