Organ Systems & Evolution
The complete obstruction of the blood will cause a myocardial infarction, or heart attack. However, partial blockage may only cause chest pain.Heart attacks may not kill the person and may simply cause heart failure. Heart failure can lead to other problems like dyspnea, or shortness of breath, and edema, or swelling of the body due to buildup of fluid the heart would normally get rid of as waste if it were functioning efficiently.Blood vessels are hollow tubes that do not only hold the blood

Molecular Biology Techniques
Due to recombination or replication errors, alleles with different numbers of repeat arise and always show two separate bands. This step occurs around 94-98 deg cel. DNA melting occurs at this temperature. High temperature breaks the H-bonding between complementary base pairs and converts a double stranded DNA into single stranded DNA. This step occurs at 50-65 deg cel. It is called annealing. It allows primers to anneal or complementary base-pair with the single stranded DNA. This double

Answers for questions
Water’s solvent properties are essential in biology since most biochemical reactions occur only in aqueous solutions. As an ionic or polar compound goes into the water, it gets surrounded by water molecules. The somewhat small size of water molecules paves way for many water molecules to bound one molecule of solute. As a result, the water’s partly negative dipoles get attracted to the positively charged constituents of the solute; this is the same with the positive dipoles.Osmosis is

A very small fraction of the sunlight energy is used for photosynthesis by the phytoplankton because optimal solar radiation is required for photosynthesis, and not all solar radiation is within the required wave length (Boyce, Lewis and Warm 592). The radiation from the sun is also too much for photosynthesis and must be dissipated to avoid causing damage to the photosynthetic apparatus. Excess energy from incoming sunlight is lost through reflection and heat. Alfred is Xb Y because he has

It is imperative to understand that despite the varying responsibilities carried out by these two agents, there are points at which they become common. One of these points is with regard to metabolic engineering. Metabolic engineering is the aspect through which scientists use transcript analysis of the various plants to identify their genetic structure for the greater understanding of biology and for imperative research. It is critical to know that this method is also used in ATP.Initially, it

Heart & Circulation
The semipermeable membranes in the human body allow the passage of water and crystalloids from the blood. Even so, it does not allow the passage of plasma proteins. Most of the body cells lie outside the blood capillaries and vessels. Consequently, all the cells will require a balanced utilization of foods and waste disposal. The arteries are created of thick walls that will allow the diffusion of materials (Agustine 2000).The arteries are involved in the transport of blood to the capillaries.

As explained earlier, the disease arises from obstructed respiratory tracts. This makes breathing difficult thus justifying the whizzing that comes naturally to the patients as they try to breath forcefully. The causes of the disease are varied including genetics and environmental factors. Genetically, parents pass the recessive gene to their parents. This implies that the disease is a portrayal of double recessive genes occurring to a child. In this context, the patients inherit the disease

NOAEL means the highest possible chemical exposure determined through the performance of toxicity tests among other methods of determination, having no observable adverse effect such as the onset of sickness even in a situation where the taking of the chemical takes place every day for the years that an organism lives. In practice, rats, mice or other animals used in the tests are forcibly exposed to a specific chemical for a specified duration. The test is undertaken several times over, with

Next translation stage begins. The ribosome moves along the mRNA molecule intermittently, triplet by triplet. During the ribosome movements, one by one new amino acids are attached to the polypeptide chain. A perfect match of amino acid to triplet provides specific type of RNA – tRNA (transfer RNA). Each amino acid presented by its own tRNA molecule, which triplet (called anticodon) is complementary to a specific triplet on the mRNA. The configuration of tRNA looks similar to cloverleaf.

At ovulation, the cervical mucus becomes fluid and elastic; this allows sperms to enter rapidly into the uterus into the fallopian tube for fertilization. Fertilization results when a sperm penetrates the egg. Five to eight days after fertilization has taken place, the blastocyst attaches itself to the uterine lining near the fundus in a process referred to as implantation. This process is completed within nine days.After the implantation, the next process involves the development of the

There are various factors that influence the heart rate both extrinsic and intrinsic. The external factors are the one that are responsible for causing the heart rate to change considerably. For a person who is involved in a more manual activity will tend to have higher heart beat compared to the one who is resting (Moser and Riegel, 2008).

Hormones are the chemical substances that are found in the human body, and are said to regulate the different processes within the body. The secretion of these chemicals leads to the balancing of all organs, and their targeted functions. If, for instance, the body is unable to secrete any hormone to its target organ, then the internal body is said to be failing (Borer 2003, p. This leads to different
