Kelvin ( K) is a unit of thermodynamic temperature and is the SI unit. The Kelvin scale in the same as the Celsius or centigrade scale but offset by 273.16. Biology uses Celsius predominantly because of the range in which organisms live. Just as a pair of shoes equals 2 shoes, a mole of shoes is 6.022×10 23 shoes.
Carrying capacity is the number of individuals a given environment can support, based on a number of interrelated factors. First, let’s look at abiotic factors like sunlight, water, and substrate. Since the globe gets uneven amounts of sunlight, both the northern and southern poles receive the least light and considerable seasonal differences.
Genetically modified organisms ( GMOs ) are those in which DNA from the desired organism is inserted in the laboratory. These are also known as transgenic organisms. GMOs are created in the laboratory using scientific methods like Recombinant DNA technology and Reproductive cloning. In Recombinant DNA technology, one or more genes from an

They occur via four essential stages in early animal development: Fertilization: the process of a single sperm cell combining with single egg cell to form a zygote. Cleavage: rapid, multiple rounds of mitotic cell division where the overall size of the embryo does not increase. The developing embryo is called a blastula following completion of
