Together, they study life over a wide range of scales: at the atomic and molecular scale, through molecular biology, biochemistry, and to some extent genetics at the cellular scale, through cell biology at the multicellular scales, through physiology, anatomy, and histology at the level of the development or ontogeny of an individual organism, through developmental biology at the level of heredity between parent and offspring through genetics at the level of group behavior through ethology at the level of an entire population, through population genetics on the multi-species scale of lineages, through systematics at the level of interdependent populations and their habitats through ecology and evolutionary biology and speculatively through xenobiology at the level of life beyond the Earth. Two of the science's most illustrious expounders were Buffon and Oliver Goldsmith, from both of whom we learn (L'Histoire generale des animaux and A History of Animated Nature) that the domestic cow sheds its horn every two years
But if you think more holistically and do the things that I recommend, then you no longer will need to resort to antibiotics because you cover your system on so many other fronts.

http://apbio12007.blogspot.com/It consists of Pulmonary arteries, and veins which pump blood to and out the capillaries of the lungs, and the Aorta which is an artery that pumps blood throughout the body. At this rate, it takes a long time (about 10-17 days) to dispose of the virus, but antibodies have now been made, and are ready to leap like a crouching tiger!YIKES! I feel bad for the virus the next time it tries to get in your blood!Then of course, after these antibodies are made, the next time the virus enters, our immune system is able to recognize it so much quicker, and therefore destroy it uber quickly.This graph shows the concentration of antibodies before and during the first exposure to the virus, and before, during, and after the second exposure
In organisms with external fertilisation, zygote is formed in the external medium (usually water), whereas in those exhibiting internal fertilisation, zygote is formed inside the body of the organism. When two parents (opposite sex) participate in the reproductive process and also involve fusion of male and female gametes, it is called sexual reproduction

http://cbse-notes.blogspot.com/2012/11/diversisty-in-living-organisms-cbse.htmlWhat happens to similarities among organisms as we go from top to bottom level? Answer: Classification systems as proposed by Linnaeus use a hierarchical system in which organisms are placed into groups, at different levels, according to the features they share. Q9(NCERT): What is the primary characteristic on which the first division of organisms is made? Answer: Cell design is the basic characteristic of first division of organisms
homeobox: Homeoboxes are relatively short (approximately 180 base pair) sequences of DNA, characteristic of some homeotic genes (which play a central role in controlling body development). (Less formally, according to Medawar's definition, a virus is "a piece of bad news wrapped in a protein.") vitamin A: A member of a chemically heterogeneous class of organic compounds that are essential, in small quantities, for life
In edited prose three-fourths of the clauses in which which is the relative pronoun are restrictive: A novel which he later wrote quickly became a bestseller. used with a noun in requesting that its referent be further specified, identified, or distinguished from the other members of a class: which house did you want to buy?

1 - The Freshwater Life
When they are close to metamorphosis they like small worms or pieces of earthworm and, in the absence of food, they bites the tails of other newt larvae. They look like little worms of a few millimetres in length (Figure 37), with a siphon in contact with the surface of the water and with the head facing downwards
They can occasionally become so numerous that the water looks red, thus this algal bloom (meaning there are large numbers of them, having nothing to do with flowers, which they do not have) is called Red Tide. These Dinoflagellates are bioluminescent, that is, they are able to produce light like lightening bugs, and at night during Red Tide, the crests of the ocean waves appear to glow in the dark
