Aquatic Adaptation Aquatic plants - also called hydrophytic plants orhydrophytes - are plants that have adapted to living in aquatic environments. -One of the main problems facing submerged aquatic plants is their inability to obtain oxygen. Unlike terrestrial plants‚ these plants cannot obtain the vital gas through their stomata because they are submerged in water. -Therefore‚ the stems‚ roots‚ and leaves of submerged aquatic plants posses aerenchyma cells‚ which supply oxygen to the rest of

approach to the modern Right Shift Theory is best explained by two alleles. One‚ the D gene‚ stands for dextral and is more frequent in the population. While the other‚ the C gene‚ stands for chance and when it is present‚ the handedness of the individual becomes highly susceptible to outside environmental factors. When the alleles are combined‚ a DD combination would yield a strongly right biased individual. A DC combination of alleles would create an individual who is mostly right handed; and a person

effect occurs when a small group from a particular population migrates to a new region and establishes a whole new population. This new population has no interbreeding action with the parent group but with different groups. This leads to a different allele frequency and speciation. The new population has different genotype and phenotype from the parent

individual has an allele for it Recessive: the form of a trait that only appears when an individual has two alleles for it Trait: a specific characteristic or feature exhibited by an organism True breeding: organisms that exhibit the same traits‚ generation after generation Cross: the fertilization of a female gamete of specific genetic origin with a male gamete of specific genetic origin Monohybrid crosses: a cross of two individuals that differ by one trait Allele: one or two more

There could also be different types of forms of the same gene they are called alleles. For example for the gene that determines your eye colour‚ there maybe could be an allele for brown or green eyes. Kim was born

mutations from alleles‚ alternate forms of a given gene that may produce differences in structure or function such as black‚ brown or blond hair in humans‚ or different mating calls in frogs. Stages of Mitosis~ 1)Parent cell. 2)Chromosomes make identical copies of themselves. 3)They line up along the centre. 4)They move apart. 5)Two daughter cells form with identical chromosomes to the parent cell. Homologous chromosomes have the same genes‚ but each homologue may have the same alleles of some

Biology Lab BLOOD TYPING All blood contains red blood cells whose main job is to carry oxygen throughout the body. Red blood cells make up almost 50% of the total blood volume. They are produced in our bone marrow and not only transport oxygen‚ but they take away CO2 and other wastes. Our blood also contains white blood cells which make up only about 1% of our total blood volume. Like the red blood cells‚ the white also are produced by our bone marrow. Our white blood cells are the first response

development of gametes. The Law of Segregation which is each gene separates during gamete formation so that each gamete transfers only one allele of each gene. The last one is Law of Dominance which states that some alleles are dominant others are recessive and that an organism with at least one dominant will show the phenotype or the result of that dominant allele. The main test crosses used are a monohybrid cross and dihybrid cross. Monohybrid meaning “one” is the simplest mating between true-breeding
