Mitosis

Summary: All biological molecules contain carbon, hydrogen, and oxygen. A carbohydrate (C,H,O) is a biological molecule consisting of hydrogen , carbon, and oxygen atoms exclusively. They are the building blocks for polysaccharides, larger more complex carbohydrates. An example of a carbohydrate is glucose (the energy source for plants). Carbohydrates are the source of short term energy in organisms. Proteins (C,H,O,N) are made of carbon, hydrogen, oxygen, and nitrogen on a base level. Proteins…

membrane. Paramecium’s specific structure of cilia ( small hairs outside of the membrane) allow the organism to respond and move due to detected stimuli from its cilia. In order to reproduce it follows through both sexual, and asexual reproduction, mitosis and meiosis. This organism is a fact which was first encountered, and compared to numerous other organisms, such as humans, who also reproduce, process metabolism, etc. Grouping similar organism together allows scientist to utilize their data…

injures endothelium cells, which is located in the tunica intima of the blood vessel. The tunica intima is the layer of the vessel that comes in contact with the blood inside of the lumen. Once endothelial cells are injured, chemotactic agents and mitosis- inducing, or growth inducing factors are released. These chemotactic agents and growth inducing factors that have been released then travel through the blood and pick up lipids. Low desnsity lipoproteins (LDLs) are highly targeted. After the…

The beauty about life is that each and every multicellular living being on this planet was created by a sperm cell fertilizing an egg cell to form a zygote. Once the zygote is formed a processes knows as mitosis allows the zygote to develop cells, tissue, and organ systems until all of the proper systems necessary for survival are formed (Witz BW 2004). Conceiving a baby is one of the most beautiful things life could bring someone, and biology is to thank…

The adult skeletal system has 206 bones,well as the network of many tendons, ligaments and cartilage. They perform many of functions in your body, it supports, creates movement, protection, your blood cell production, your calcium storage and the endocrine regulation. Bones in our body support us and protect us. The bones of the legs, pelvis, Are back hold up the body to maintain are posture, the jaw supports the teeth, mostly all the bones in our body support our muscles and tendons in…

The moss Physcomitrella patens is an attractive model system for plant biology and functional genome analysis.(1-7) It shares many biological features with higher plants (vascular plants) but has the unique advantage of an efficient homologous recombination system for its nuclear DNA.(2,3) This allows precise genetic manipulations and targeted knockouts to study gene function, an approach that due to the very low frequency of targeted recombination events is not routinely possible in any higher…

Imagine a young child given a life changing opportunity to be freed from the tight fist Cerebral Palsy suffocates her with, given a life changing opportunity providing him/her with a brighter future, given A young girl by the name of Chloe Levine suffered from Cerebral Palsy, which was never thought to be curable. Through the use of stem cell research conducted at Duke University, however, her recovery from this neurological disorder was cured. The method the research center used was adult stem…

Cells are the basic building blocks of life. They are the smallest structural unit in an organism, and the organism must continuously create more cells in order to live. New cells are created through a process called cell division, or mitosis, where one cell turns into two cells. This process is necessary for life, but occasionally the cells do not do what they are supposed to. Cancer is one example of cell malfunction. A DNA mutation can disrupt the genes in the cell and cause it to produce…

Severe Combined Immune Deficiency as described by the immune deficiency foundation, is a “cellular immunodeficiency and a potentially fatal primary immunodeficiency in which there is combined absence of T-lymphocyte and B-lymphocyte function” (Immune Deficiency Foundation IDF, 2016). The lymphatic system comprises of organs and tissue that produce immune cells and one of their main functions is to confer immunity to every part of the body. The function of the T-lymphocyte and B-lymphocyte in the…

Evaluation Strategy Student Learning The Next Generation Science Standards which are endorsed by the National Science Teachers Association proposes that students should be taught to analyze and interpret data, be able to provide evidence that plants and animals have traits inherited from parents, and that variations of these traits exist in other organisms. This unit’s purpose is to make students aware of the concepts of genetics and inheritance and other related concepts. Students will learn…
