So in the last unit we studied about chemical basis of life. Now just Focus for a moment on biology‘s subject‚ ‗life‘. All living things on earth are characterized by cellular organization‚ growth‚ reproduction‚ homeostasis and heredity. These characteristics define the term life. Then what is inheritance? Inheritance is something you possess from your ancestor and carried along‚ it may be any asset‚ money or anything but when we connect with the life what we will take from our parental generation

“try to understand what it is to be human” Biocultural approach: the relationship between what humans have inherited genetically and what they learn culturally Holistic: understanding people with all aspects of human nature Comparative: cross cultural Ethnocentric: a view that is centered on a specific ethnic group (usually ones own) belief in the superiority in ones ethnic group Cultural Relativism: a view that considers human interaction and behavior within their own culture.

BACTERIAL TRANSFORMATIONS USING PVIB II. INTRODUCTION Transformation is the manipulation of a bacterial cell’s DNA in order to alter the cell’s genotype or phenotype by absorbing free DNA from its surroundings. In this lab‚ pVIB plasmid will be used. A plasmid is a segment of DNA that can incorporate itself into the bacterial DNA. Although is not required for growth of the bacterial cell‚ plasmids can provide advantages in stressful environments such as the ability to adapt as environmental

Outline the impact on the evolution of plants and animals of: a. Changes in physical conditions in the environment o Rising and falling sea levels – land and ice bridges across continents have affected distribution and therefore evolution when these bridges disappeared and populations were isolated

Large genetic variations in its maturity group help in its wide adaptation for different environments and cropping systems. In general‚ short-duration genotype of pigeonpea grown as sole crop while medium and long duration genotype are habitually cultivated as intercrop or mixed crop with other short duration cereals and legumes crop species. Apart from this‚ its main use as de-hulled split peas‚ its juvenile seeds and pods are also consumed

to the other‚ and heterozygotes exhibit an intermediate phenotype (incomplete dominance). Each dark-skin allele in the genotype adds pigment by increasing melanin production. There are seven different shades of skin color ranging from very light (aabbcc) to very dark (AABBC); most individuals have the intermediate skin color (AaBbCc). A cross between two individuals with intermediate skin color produces offspring with a range of phenotypes (bell-shaped curve). According to the article‚ some suggest
