30.1 ANIMAL DEVELOPMENT BEGINS WITH REPRODUCTION Reproduction, growth, and development are shared features of ALL multicellular life. A. REPRODUCTION IS ASEXUL OR SEXUAL ASEXUAL REPRODUCTION – offspring contain genetic info from only one parent and are identical to the parent and each other. Advantageous in environments that don’t change much over time. EX. Include aphids, some types of lizards SEXUAL REPRODUCTION – requires genetic info from two parents. Advantageous in changing environments

Cell wall Plant cell and animal cell are different in shape, size and also has few different organelles which function in different way. One of the main difference between plant cells and animal cells is that plant cells have a cell wall, whereas animal cells don't. Instead of cell wall animal cells have cell membrane but the plant cells have both cell wall and cell membrane. The cell wall in plant cells work as a protection layer outside the cell membrane which also provides structure for the

MEMBRANE STRUCTURE AND FUNCTION Fluid-mosaic model for biological membrane In human beings, all cells are surrounded by a cell membrane, are called the plasma membrane. Our current understanding of the structure of biological membranes is summarized in the fluid-mosaic model. It describes both the "mosaic" arrangement of proteins embedded throughout the lipid bilayer and also the "fluid" movement of lipids and proteins alike. Structure of membranes Biological membranes are sheet-like structures

Elizabeth Gossan Inherited genetic diseases - discuss Lynne Hampson 1,684 30/08/2014 Inherited Genetic Diseases – discuss. DNA is a large and complex molecule made up of a sugar phosphate backbone which consists of deoxyribose sugar bonded with phosphate groups. Then branching off the sugar phosphate backbone are complimentary nitrogenous base pairs which are Adenine, Thymine, Guanine and Cytosine. Transcription happens in the nucleus, where the double helix ‘unzips’ allowing mRNA to

Final Report Outline * Name of the enzyme: Catalase found in chicken liver. * The name of the organism is chicken (liver). * The substrate is hydrogen peroxide (H2O2)|. * Hypothesis: If the catalase in the chicken liver is exposed to hydrogen peroxide, it will cause a chemical reaction. This reaction will result in the destruction of hydrogen peroxide in the chicken liver, which is harmful to the cells; the enzyme catalase works best in acidic solutions and enzymes are denatured

What did you find interesting about this article? I find it interesting because I had no idea there was an animal called Pikas, but they are so cute. Its crazy that the death of animal species tells us how are climate change is not good. What impact, if any, does this news have on you personally? It makes me more aware of how bad climate change is in California. I would prefer those Pikas to be transferred to a colder state, is it possible to do that? What information would you like clarified
