Meiosis 1 and Mitosis are very similar events‚ however‚ they have certain differences. One difference is crossing over. Meiosis 1 does cross over and because of that‚ it creates genetic changes. Mitosis ‚ on the other hand‚ does not cross over. Something else that is different is the way it occurs. Meiosis 1 is sexual but Mitosis is asexual. Another change is the number of divisions that each event goes through. Meiosis 1 goes through 2 divisions which ends up having 4 haploid cells‚ however Mitosis

BIO Microscopy‚ Mitosis‚ and Motility Lab Discussion Questions In the Microscopy‚ Mitosis‚ and Motility lab‚ the class used the Compound Microscope. The Compound Microscope helped examine the prokaryotic and eukaryotic cells‚ observe the different stages of mitosis‚ and compare modes of motility used by protists. The light compound microscope works with the aid of lenses such as the eyepiece. These lenses help keep the focus of the light on the eye. The fine and course adjustments also assist with

Cell Cycle Definition- The process of the cell to divide into new cells. Interphase Description- the phase that occurs before cell division‚ the preparation for cell divisions Stages: G1- Rapid growth of the cell‚ metabolic activity. S- Synthesis‚ DNA replication. G2- Getting ready for cell division. Centrioles replicate Mitosis and Cell Division Function- To grow repair and maintain the cells in the body along with the reproduction of those cells. Results- Two identical daughter

Structures and processes involved in the movement of substances into and out of cells. Epithelial cells – Epithelial cells are also referred to as eukaryotic cells. These types of cells have a unique nucleus and contain membrane-bounded organelles. Epithelial cells absorb and secrete‚ and the structures of a cells organelles can be viewed from an electron microscope. The nucleus – the nucleus of a cell contains most of the cell’s genetic material‚ organized as multiple long linear DNA molecules

Chromosome 11 is one of the 23 pairs of chromosomes in humans. People normally have two copies of this chromosome. Chromosome 11 spans about 134 million base pairs (the building material of DNA) and represents between 4 and 4.5 percent of the total DNA in cells. Identifying genes on each chromosome is an active area of genetic research. Chromosome 11 likely contains between 1‚300 and 1‚700 genes. Genes on chromosome 11 are among the estimated 25‚000 total genes in the human genome. There are many

Opposites Do Infact Attract Siddhartha‚ the celebrated book by swiss author Hermann Hesse‚ is acclaimed for its spiritual story arc. Nonetheless‚ it is also a minefield for symbolic themes such as the recurring water imagery and the omnipresent circle motif.

Unity is explored in many ways throughout the whole book‚ but one way in particular stands out: the idea that opposites

There is a 25% chance that Allison and Tim will have a baby boy who is heterozygous for Tay-Sachs. b. No‚ the baby boy will not have Tay-Sachs he will be a carrier for the disease.
