Chapter 11.1 & 11.2 Notes Section 11.1 1. Every living thing has a set of ? inherited from its parents. 2. After becoming a
?, Mendel spent several years studying ? and mathematics at the University of Vienna. 3. During sexual reproduction, male and female reproductive cells join, a process known as ?. 4. Pea flowers are normally ?, which means that sperm cells in pollen fertilize the egg cells in the ? flowers. 5. When Mendel crossed plants with ? characters for the same trait, the resulting offspring had only one of the characters. 6. A ? is a specific characteristic, such as seed color or plant height, that varies from one individual to another. 7. Filius and filia are the Latin words for ? and ?. 8. The offspring of crosses between parents with different traits are called ?. 9.To Mendel's surprise, all of the offspring had the character of only ? of the parents. 10. Mendel's first conclusion was that biological inheritance is determined by ? that are ? from one generation to the next. 11. Scientist calls the chemical factors that determine traits ?. 12. Mendel's second conclusion is the ?. 13. The principle of dominance states that some alleles are ? and others are ?. 14. When Mendel allowed the F1 plants to reproduce by self-pollination the traits controlled by ? alleles reappeared in about ? of the F2 plants in each cross.
The writing of a person is controlled by an region located in the left part of frontal lobe of the brain which is known as the Broca's area.
Writing is a motor impulse send by the brain to the hand and fingers.
However, no two individual can have the same hand-writing.
This is because hand-writing is not only dependent on the brain to hand motor co-ordination.
It also depends upon the psychology, mentality, thought process, state of mind, nature of the person and also the influence of the surroundings on the person.
It also depends on the preference of the person to keep his writing artistic or simple or illegible.
All these factors can never match between two persons.
This is the reason, no two persons can share the exactly same hand-writing.
Due to urease activity, bacteria are able to use urea as a sole nitrogen source and produce ammonia, which increases the pH in the proximal environment, causing Ca2+ and CO32- to precipitate as CaCO3.
