Flow tube radius change has a direct effect on flow rate. As evidenced in this lab, when flow tube radius was…

Berlese Funnel Lab Report

Antonio Berryless was an Italian entomologist. He worked on pest insects (arthropods), usually those of fruit trees. Arthropods are the most successful animals on the planet. They make up over three. Fourths of all currently known living and fossil organisms. But, many still remained undocumented. Berryless funnels are used for extracting arthropods from soil and…

Cell Cycle Lab Report

Hypothesis Procedure: predict that all cells somatic will suffer all the division of mitosis multiple times n their lifetime; the product would be able to see the chromosomes in a stage of mitosis. It is predicted that the cells won’t be seen clears or big enough, but is going to give ideas or example wows…

Gram staining lab report

Gram Staining Lab Introduction Gram staining is a very important technique used in biology labs all over the world. It is a technique used to differentiate types of bacteria using certain physical and chemical characteristics Of their cell walls. Gram positive bacteria (which show up purple after the gram staining process) have a very thick…

Fetal Pig Dissection Lab Report

In addition to this, the fetal pig dissection helps students better interpret the relative position and sizes Of organs, as well relation between organ and organ system. Hypothesis Grout, Anvil and had hypothesized that the fetal pig’s internal systems should be slightly alike, due to the fact that pigs are on the same level food…

Chlamydomonas Lab Report

The power stroke consists of beating stiffly in one direction, while during the recovery stroke the cilium is pulled back in floppy fashion close to the cell surface, thereby offering little resistance. Once in position, it straightens out and the stiff power stroke begins again. Human cilia or flagella are found in traditionally in three…
