how homeostatic mechanisms control temperature‚ breathing and heart rate and evaluate the importance of homeostasis in maintaining healthy functioning of the body. Homeostasis Homeostasis is the maintenance of a constant internal environment in organisms. It involves volume of blood and tissue fluid within restricted limits‚ it also maintains chemical makeup of the blood. Autonomic control systems throughout the body maintain temperature and water levels‚ which are required for cells to function

Five Levels of Organization of Living Things or Organisms: 1. Cell - The basic unit of life that makes up all living things. 2. Tissue - A group of cells‚ that are alike‚ working together form tissue. 3.Organ - A group of tissue working together forms organs. 4. Organ system - Groups of organs working together. 5.

from the fertilized egg. The fourth property of all living organisms possess is that populations of organisms evolve over many generations. Adaptations are inherited characteristics that allow organisms to survive in a particular environment. The seahorse has evolved and adapted camouflage. Which property is NOT a property of all living things? Ability to move* Properties of living things: having order‚ reproduce‚ evolve. Organisms that produce sexually do not produce exact copies of themselves

Section One : In the discipline known as taxonomy‚ scientists classify organisms and assign each organism a universally accepted name. The first part of the scientific name—in this case‚Ursus—is the genus to which the organism belongs. Agenus(JEE-nus; plural: genera‚ JEN-ur-uh) is a group of closely related species. Linnaeus’s hierarchical system of classification includes seven levels. They are—from smallest to largest—species‚ genus‚ family‚ order‚ class‚ phylum‚ and kingdom

Duplicates its DNA and divides into two new organisms. 8. Explain the process of budding. (2pts) A small part of the parent organisms body breaks off and grows into a new organism 9. What is vegetative propagation? (2pts) Runners/rhizomes/tubers spread from the parent plant and form “plantlets” at the ends of vines or leaves 10. Explain what happens during fragmentation/regeneration. (2pts) Part of the parent’s body breaks off and forms a complete‚ new organism 11. Describe the process of conjugation

We chose a gene of our choice to compare to humans‚ to see if any other organisms have the gene that we were looking at other than humans‚ and if so how much do we share. Gene: Actin The initial gene that we started with was actin and there was so many relationships between humans and other organisms. I was surprised how closely related we are to others. It showed a cladogram of the relationships. What other organisms have it The actin gene organization and

Mitosis and Meiosis Mitosis and meiosis are both important to a living organism because they represent cell divisions that are very important to every living organism because without cell division all living organisms would fail to reproduce‚ eventually dying out. Cell division plays a very important role in the life cycle of a cell. Mitosis and meiosis are important to living organism because they help living organisms to grow‚ develop‚ and reproduce. Mitosis is a type of asexual reproduction

or skin cells. What are these things called cells? Cells are the smallest living things. You’ll be learning a lot about cells in this course. For now‚ however‚ I’ll introduce you to just a few basic things about them. Cells are extremely tiny organisms that carry out all of the functions of life inside a thin layer of “skin” called (unimaginatively) the CELL MEMBRANE. A good analogy is the thin‚ flexible skin of a soap bubble. The cell membrane keep the cell together. Without the membrane‚ all
