Biology HL Portfolio The Cell and Cell Theory [pic] The cell The word cell comes from the Latin word “cellula”‚ which means a small room. The cell is the smallest unit of a living organism‚ also known as “the building block of life”. Every living organism is consisted of a cell. There are bacteria (unicellular organisms)‚ and multicellular organisms. There are different types of cells‚ prokaryotic and eukaryotic cells. All cells come from preexisting cells. “Every cell is self-maintaining;

Chromosome 11 is in group C‚ it is of medium size‚ its relative length is 4.82 Chromosome 11 is submetacentric‚ meaning that the centromere is closer to one end‚ causing one longer arm and one shorter arm. The centromeric index for chromosome 11 is 40.46. Calculations can be seen below. Centromeric index = (p / p + q) x 100 (1.95 / 4.82) x 100 = 40.46 The protein that HBB gene encodes is beta-globin. Beta-globin is a component of hemoglobin. Hemoglobin is found in red blood cells‚ and it normally

The word “syndrome” then was replaced by “sequence” because the pathogenesis of the condition occurs through a chain of events. The sequence include small jaw (micrognathia)‚

The common cause of congenital myasthenic syndromes is genetics‚ affecting the junction where the nerve triggers muscle activity. The inherited autosomal recessive gene exists in both parents‚ who pass the mutated gene to the offspring. The syndrome appears shortly after birth or early childhood. Severity ranges from minor to increasing concentrations of muscle weakness. There are over twenty different genes known to cause congenital myasthenic syndromes‚ as different as each individual. Sometimes

Samuel Heidenreich Miss.Tatu Biology March 5‚ 2015 Introduction In the Mitosis lab an onion root was observed under a microscope to observe whether or not cell division takes place. Also‚ whether cells replicate in order for it to reproduce. By observing the onion root under the microscope it allows many layers to be looked at through each cell division. The goal of Mitosis is the replication of cells to produce multiple like cells. The steps involved in Mitosis are what is known as

Many experts argue over where humans originated from and which human migration and evolution theory is most reliable. With a good hypothesis‚ factual evidence‚ and logic‚ many theories seem plausible. However‚ there are many holes in each theory (whither it be the out of Africa theory‚ the out of Australia theory‚ the out of Asia theory‚ or the multiregional theory) which leaves many puzzled when it comes to choosing which theory is the most authentic and trustworthy. Out of Africa The
