Live in both fresh water and marine habitats. Some are found in soil‚ and many have adapted to parasitic life on the body of marine animals or internal organs of both aquatic and terrestrial animals. Amoeba reproduces asexually by binary and multiple fissions. They eat algae‚ bacteria‚ other

of transmission of characters both in the animal and plant kingdom which seemed to defy every known genetic law assuming the whole of inheritance to be through the nucleus. The inheritance of flower color in 4° Clock plants‚ Kappa particles in Paramecium etc‚ cannot be explained on the basis of nuclear inheritance. What then is the secret of their inheritance pattern? Scientists started looking for

BI108 Animal Biology Lab Report Practical 6: Osmoregulation and Excretion of Vertebrates and Invertebrates Title: Osmoregulation and Excretion of Vertebrates and Invertebrates Abstract: In every aspect of an environment‚ there is a variance in the concentration of fluids present in the environment and the bodies of organisms. Osmoregulation is the regulation of water and ion concentrations in the body. Keeping this regulation precise is critical in maintaining life in a cell

Define Ocular: (eyepiece) Objective: provides magnification of 4‚ 10‚ 40‚ and 100 power Low power: 4X 10X High-and-dry: 40X Oil immersion objective: 100X Fine adjustment: is essential for final‚ sharp focusing Coarse adjustment: is used initially for rough focusing Parfocal: as you cane from one objective to another you will find that your microscope is very close to a final focus Sub stage condenser: light focusing lens Iris diaphragm: used to regulate the

The Central Dogma. This hypothesis was described by Crick in 1958. In 1953‚ Watson and Crick were the first to determine the true crystalline structure of DNA‚ using model building and then X-ray crystallography. Once the DNA structure was determined‚ the mechanisms behind inheritance‚ information flow‚ and gene function fell into place. Overall the flow of information is depicted as: DNA --> RNA --> protein. Both DNA and RNA can be replicated (i.e. DNA is synthesized from DNA‚ and RNA from RNA)

Exercise 13 MITOSIS: REPLICATION OF EUKARYOTIC CELLS ANSWERS TO QUESTIONS 1. a. Mitosis and cytokinesis are often referred to collectively as "cellular division." Why are they more accurately called cellular replication? The result of mitosis is production of two cells (replicates) identical to the parent cell. The genetic material is replicated rather than divided. b. Does the cell cycle have a beginning and an end? The organization of our study of cellular events indicates a beginning and

these are different of the previous ones because of they have a nucleus. The principal characteristics of these are that they are mainly aquatic‚ and when some protistas move around‚ others stay in one place. Some examples of protistas are algae‚ paramecium‚ and amoeba. Fungi are usually motionless organisms and belong as their name show to the kingdom fungi. Most fungi are multicellular and consist of many complex cells. They absorb nutrients from parts of plants that are decaying in the soil for

Roger’s first article‚ "On the Excretory Apparatus in Paramecium‚" appeared in Science in 1924. She obtained a master’s degree in 1926. In 1927 Roger’s tutor‚ Ernett Just‚ invited her to come work with him at the Marine Biological Laboratory in Woods Hole‚ Massachusetts. While working in the lab roger studied
