INTRUDUCTION Experiments with animals In this project we chose to write about experiments on animals because we are owner of pets at home and this topic is pest us!: this animals have life too ‚ this animals are like humans they are a part of our family-they have feelings/thoughts/rights like a humans and the experiments are cruel and it make them to suffer!!! There exaggeration trials assessing the necessity of understanding the extent of suffering and a lot of experimental animals When we

detail Do you agree with the use of the animals in experiments? Why or why not? Fully explain your response. Points to consider in your response: The purpose of the study The type of study (observational‚ medical‚ etc) The type of animals being used The use of animals in experiments can be extremely helpful in understanding humans. Animals have similar physiology‚ genetics‚ similar learning and emotional processes as humans. I believe animal experiments are necessary in order to advance medical

Comparing Plant and Animal Cells Hypothesis: I predict I will see the following organelles when observing a plant and animal cell under a microscope: the cell membrane‚ cell wall‚ nucleus‚ and the endoplasmic reticulum. Frog Blood: Analysis: 1. The shape of the frog blood cell was in a circle‚ or oval. The edges were a little irregular‚ but it could still be identified as‚ basically‚ a circular shape. 2. The cells were produced by an animal‚ a frog. 3. The cell wall was not present

Osmosis in Plants Outline: To investigate the effect of varying concentration of a certain sugar solution on the amount of osmotic activity between the solution and a potato chip of a given size. Definition - Osmosis: Movement of a solvent (liquid) through a semi-permeable membrane separating solutions of different concentrations. The solvent passes from a less concentrated solution to a more concentrated solution until the two concentrations are equal. All

abnormalities and diseases‚ many of these animals are unable to live on. As for animals’ daily living conditions‚ they spend their lives in cages‚ not being able to live freely with choices or communicate. They never get to experience the outdoors of fresh air and sunshine‚ instead‚ they are contained within bars and walls. Not only that‚ their cages are small and crowded‚ and they live with loud noises and bright lights that are known to cause stress in animals. Days after days in laboratories‚ they

The Osmosis Scientific Paper Emily N. Charbonneau Grand Valley State University The point of this experiment was to observe if the different concentrations of sucrose would change the speed of osmosis. Osmosis is a process of a fluid that will pass through a semipermeable membrane into a solution which most of the time has a higher concentration. Osmosis will be demonstrated throughout the lab. The importance of osmosis in a plant and animal cell there is a cell membrane‚ which helps liquids and

Animal Cell Song I’m here to talk to you about animal cells. They are made up of many organelles. Chromosome‚ nucleus‚ those are a few They need them to live like me and you. Well we’ll start with the nucleus the “command center.” It’s the brain of the cell and keeps it away from danger. It’s a safe haven for the chromosomes. They store DNA like our own. The precious DNA carries our genes. Genes tell the cell what to do like info. machines. Now let’s talk about the mitochondrion

“Cell Transport Lab” Hypothesis: I hypothesis that there will be a movement of molecules out of the egg‚ and will move into the water solution. Osmosis will occur within the egg‚ and in the process the molecules of the egg will diffuse.

is an animal cell? According to softschool website an animal cell is a cell that can dominates most of the tissue cells in animal’s cells. An Animal cells are very different looking from plant cells because they don’t have cell walls. Most animal cells have about 3 main parts and they are cytoplasm‚ cell membrane‚ and nucleus. (www.softschools.com/science) Cell membrane- “The function of the cell membrane is to surround the cytoplasm of any living cell from the outside environment. The cell membrane
