Biology: Walter Sutton and inheritance


Walter Sutton


Walter Sutton - (1877-1916) was an American geneticist who studied the cells of grasshoppers. He was trying to figure out how sex cells form. During his studies, he examined  sex cells many different stages of formation. He was interested in the movement of chromosomes during the formation of sex cells. He said that chromosomes were the key to understanding how offspring come to have traits similar to those of their parents.
Chromosomes carry Mendel's hereditary factors, from one generation to the next. In other words, genes are located on chromosomes.

Chromosome Theory of Inheritance 
Genes are carried from parents to their offspring on chromosomes.

Meiosis is the process by which the number of chromosomes is reduced by half to form sex cells-sperm and eggs.
During meiosis, the chromosome pairs separate and are distributed to two different cells. The resulting sex cells have only half as many chromosomes as the other cells in the organism.

Chromosomes
Chromosomes are made up of many genes joined together like beads on a string.
Although humans have only 23 pairs chromosomes, your body cells contain more than 60,000 genes. Each of the genes controls a particular trait.

Physics: Friction and Gravity

The strength of the force of friction depends on two factors: the types of surfaces involved and how hard the surfaces push together.


il_fullxfull.250203781There are different kinds of friction:
  • sliding friction - when one solid surface slides over another.
  • rolling friction - when a object rolls over a surface.
  • fluid friction - when an object moves through a fluid. 


Gravity

Free fall - when the only force acting on a falling object is gravity.
Terminal velocity -  the maximum velocity a falling object achieves.

Newton's First and Second Law of Motion

Newton's First Law of Motion
Law of inertia

An object at rest will remain at rest and an object that is moving at constant velocity will continue moving at constant velocity unless acted upon by an unbalanced force.

Newton's Second Law of Motion

The net force on an object is the product of its acceleration and its mass.

F = ma

F - Force
m - mass
a - acceleration 

1N = 1kg  1m/s²


Image result for second law of motion

Biology: Gregor Mendel - intro to genetics



Trait: A characteristic that an organism can pass on to its offspring through its genes.

Gene: A segment of DNA on a chromosome that codes for a specific trait.

Alleles: The different forms of gene.

Dominant alleles: An allele whose trait always shows up in the organism when the allele is present.

Recessive alleles: An allele that is masked when a dominant allele is present.

Hybrid: An organism that has two different alleles for a trait (heterozygous organism).

Gregor Mendel oval.jpgGregor Mendel (1822-1884) - Austrian scientist, priest, teacher. He studied genetics with his pea plants in the monastery. And wrote a report why some peas are tall and some are short.  Back in his days no one believed his theory. Now he is considered the father of modern genetics.
