Animal Adaptations

Context As students approach this Animal Adaptations lesson, bear in mind that, according to research, most lower elementary school students are still forming a basic understanding of how animals survive in their respective environments. For example, many students understand a simple food link between two animals, but many still assume that animals are still independent of each other and depend on humans to provide food and shelter.

Learn Science at Nature. Tree of Life Web Project. The Tree of Life Web Project (ToL) is a collaborative effort of biologists and nature enthusiasts from around the world.

Tree of Life Web Project

On more than 10,000 World Wide Web pages, the project provides information about biodiversity, the characteristics of different groups of organisms, and their evolutionary history (phylogeny). Each page contains information about a particular group, e.g., salamanders, segmented worms, phlox flowers, tyrannosaurs, euglenids, Heliconius butterflies, club fungi, or the vampire squid. ToL pages are linked one to another hierarchically, in the form of the evolutionary tree of life. Starting with the root of all Life on Earth and moving out along diverging branches to individual species, the structure of the ToL project thus illustrates the genetic connections between all living things.

Chromosomes then duplicate to produce SISTER CHROMATIDS (or HOMOLOGOUS DYADS). Prophase I: Dyad pairs align to create "TETRADS", non-sister chromatids connect and trade sections at a "CHIASMA", a process called "CROSSING OVER". Metaphase I: SPINDLE FIBERS attach to each dyad at the KINETOCHORE. Tension from spindle fibers aligns the tetrads at the cell equator. The Biology Project: Cell Biology. En español Cell Membranes Learn that membranes are fluid, with components that move, change, and perform vital physiological roles as they allow cells to communicate with each other and their environment.

Cell Signaling Learn that living organisms constantly receive and interpret signals from their environment. Cells of multi-cellular organisms also receive signals from other cells, including signals for cell division and differentiation. Studying Cells Introduce yourself to the cell as the fundamental unit of life and the scientific method. The Cell Cycle & Mitosis Understand the events that occur in the cell cycle and the process of mitosis that divides the duplicated genetic material creating two identical daughter cells. Meiosis Understand the events that occur in process of meiosis that takes place to produce our gametes. Prokaryotes, Eukaryotes, & Viruses Learn about the cells that make up all living systems, their organelles, and the differences between living cells and viruses.

A plant needs light, warmth, water and nutrients to grow well. Roots take up water and nutrients from the soil. They also keep the plant steady and upright in the soil. The stem carries water and nutrients to different parts of the plant. How plants work - Science (4) - ABC Splash - Overview Plants are the only living things that can make their own food.

They do this during the day while it's light, using a process called photosynthesis, which uses carbon dioxide and produces oxygen. During the day and night plants take in oxygen and release carbon dioxide through respiration. Discover just how important plants are to life on Earth.

What would disprove evolution? If evolution is a scientific theory worth its salt, then there must be some conceivable observations that could show it to be wrong. I just wanted to put down, for the record, what some of those observations might be. First, let’s reprise what I see as the major components of the theory of evolution. Evolution occurs, that is, there is gene frequency change in populations over generations.Significant evolution takes time—that is, it usually (though not always) requires hundreds to thousands of generations to occur.

It is not instantaneous, and it is the population and species rather than the individual that evolves.Lineages of organisms split, or speciate, so that the single lineage that gave rise to life 3.5 billion years ago has undergone numerous splitting events to produce the millions of species alive today (and also the even more millions that went extinct).The converse of #3: any pair of living species has a common ancestral species some time in the past.
