What is an orbit? An orbit is a regular, repeating path that an object in space takes around another one. An object in an orbit is called a satellite. A satellite can be natural, like the moon, or human (or extraterrestrial?) -made. In our solar system, the Earth orbits the Sun, as do the other eight planets. What causes an orbit to happen? Wonderopolis | Where the Wonders of Learning Never Cease | Wonderopolis What are the orbital lengths and distances of objects in our solar system? Space is huge, and even our immediate environment is gigantic. We are the third planet from the Sun, and the third of three inner planets, all of which are right next to the Sun compared to others. The picture below shows the planets in their orbits on the orbital plane. Image from The Nine Planets, a Multimedia tour of the Solar System by Bill Arnett The planets are far from the Sun, travel huge distances in space, and take a long time to do so. The distance from the Sun is average because the orbits of the planets do not make perfect circles, but rather very slightly flattened ones, or ellipses. What causes an orbit to happen? What are planets made of? How do we know what's in space?

team6cell / Mitosis Mitosis By Vicky The Mitosis has seven phases in which it makes two daughter cells and those daughter cells come from a single parent cell. Mitosis has many phases, such as, Prophase, Metaphase, Anaphase, Telophase, Interphase, Prometaphase, and Cytokinesis. Each of these phases have a process in which something is created. In the second phase of Mitosis, Prophase, the chromatin condenses into a chromosome(s). Metaphase, the fourth phase of Mitosis, is when all the chromosomes are aligned in the metaphase plate. Anaphase, the third to last phase of Mitosis, is when the chromatids that are now known as chromosomes, separate. Telophase is when the chromosomes are now splitting into two and the cell division starts.Telophase is, "Daughter chromosomes arrive at the poles and the microtubules disappear. Last but not least, Cytokinesis is when the actual cell division happens. Walter Flemming was one of the few people who helped with the finding of Mitosis. Resources: 4.Life science Lab Book

Mitosis Genetics and Heredity Heredity and Evolution – What processes are responsible for life’s unity and diversity? 8.2 - Reproduction is a characteristic of living systems and it is essential for the continuation of every species. Heredity is the passage of genetic information from one generation to another. Some of the characteristics of an organism are inherited and some result from interactions with the environment. C 25.

Mitosis: Interphase: Not a part of mitosis Cell growsDNA replication happens (humans - 46 chromosomes become 92 chromosomes)Cell grows, makes additional organelles to prepare for cell division Mitosis Stages: Prophase: Chromatin condenses, becoming visible chromosomes appear inside the nucleusEach chromosome is made of 2 identical sister chromatids connected at the centromereNuclear membrane and nucleolus break downCentriole and spindle fibers appear Metaphase: Anaphase: Telophase: Chromosomes groups become a nucleus when the nuclear membrane reforms
Mitosis Explained with Diagrams Cell division is a process with sequence of steps that enables organisms to grow and reproduce. Genetic material is replicated in parent cells and is distributed equally to the two daughter cells. Cells undergo a period of growth called interpahse before entering mitosis. During the interphase, the genetic material replicates and the organelles prepare for division. In the process of mitosis, the parent's cell genome is transferred into the two daughter cells. The daughter cells are similar to each other and to their parent cell.The cell's genome is composed of chromosomes that are complexes of tightly coiled DNA that contain the genetic material which is vital for the proper functioning of the cell. The process of mitosis begins when the chromosomes condense.
Science of Atoms and Molecules SAM was designed to assist the realignment of high school science disciplines into a physics, chemistry and biology sequence. Funded by NSF from 2006-2010*, SAM activities provide critical atomic-scale science content that can enable and take advantage of the revised sequence. The atomic and molecular model-based activities facilitate not only the disciplinary order but also four thematic sequences: Motion and Energy, Charge, Atoms and Molecules, and Light. This NSF-funded project has achieved its goal of providing the materials and professional development resources that schools need to implement high-quality secondary science curricula with a unifying theme of atoms and molecules. The SAM materials enable students to acquire a progressive understanding of the centrality of atomic-scale phenomena and their implications. Biology, chemistry, and physics courses do not have to be entirely re-written to profit from the new sequences. Connecting the Sciences How Do People Learn? 1. 2. Summary
