Conversely, due to the intense dust that emanated from the Asteroid and planet’s collision, their existence came to a halt. Since, the deposited dust into the atmosphere blocked the sunlight from reaching the planet’s surface (Benton 64). Consequently, affecting

Below is the calvins cycle where it takes place. Temperature- different plant varieties requires different temperatures.the correct amount of temperatures should

Oil contaminates the water and causes death to sea animals. It is prone to continue as ships and barges continue sailing in the water and of the importance is how to clean up the spills the moment they occur. Oil is less dense than water, and it hence floats on

A population pyramid is a highly effective tool that holds great potential to help experts examine and record population statistics very closely. It helps to identify the population structure and also makes it quite easier to make assumptions about a country’s future prospects. These pyramids lend so much validity and sense to the statistics for social scientists and policymakers.

Evolution as explained by natural selection demonstrates how the fitness of the organisms is enhanced over time thus enabling to cope with the environmental challenges. In ecology, niche refers to a species’ relational position in an ecosystem. An ecological niche thus

The relationship between concentration of a substrate and rate of reaction depends on the affinity of the enzyme for its substrate. This is expressed as the michaelis constant (Km) of the enzyme, which is an inverse measure of affinity. Enzyme inhibitors are

The optimum pH range was found to be 5-6 and the given enzyme does not work at all in the pH 3. Enzymes are protein molecules present in all the living cells. They act as biological catalyst for speeding up the reactions by lowering the energy barrier. Enzymes are made

Now scientists across the globe are hypothesizing that the fear factor can be eliminated within a given time frame. To assess the possibility of how fear memory can be erased, the

for this blood to be of use to the human body, it must carry oxygen to other parts of the body and carbon four oxide with other waste material from other body systems. This carbon dioxide is then exchanged with oxygen in the lungs (Batzel and Bachar, 370). Thus, after being

Physicians have long known that women having mutations in 2 specific genes- BRCA1 and BRCA2- usually have a high ovarian and breast cancer risk and have now begun figuring out which mutation is worse than the other one. Consequently, doctors have realized that some of these mutations might minimize a woman’s risk of getting ovarian or breast cancer to much lower levels than thought previously.

A person with MS encounters challenges when speaking, talking, walking, thinking, or swallowing. It is not yet clear as to what leads to the development of multiple sclerosis, although vitamin D is believed to play a major role. Researchers agree that vitamin D is essential

 They should also be subdivided into groups depending on how traumatized one was and how critical their condition is. They are guided through the emotional turmoil that they experience by well-trained personnel without any cost. They narrate the feelings they went through in order to relieve them of the depression, Later; they too can volunteer and help others because they have the first-hand experience.

The first step in conducting the experiment involves the identification of the dependent, independent variables and constants that might be relevant for the experiment. Then, a hypothesis is formulated that defines the relationship between the variables. The validity or the invalidity of the hypothesis will bear the results of the experiment.

The flowering plants are the majority of the plants and this category includes most trees, vines, flowers, legumes, and vegetables. This is the most productive category as it contributes to humankind through medicine, herbs, and foods (Germ 96). This group differs from the conifers because they often grow their seeds in an ovary that is embedded in a fruit or a flower.

The study was byword for unethical medical experimentation and racist. It concerned about 400 impoverished African-American men who were found to be suffering from

Their importance in our habitat leads us to study thoroughly about them. Since they cannot be seen by the naked eye, their identification is considered a tough job. It requires so much perfection to work with microorganisms in order to reduce the chances of contamination. Microorganisms contribute to a high extent of the spread of disease.

Involves the movement of macromolecules molecules through nuclear pores to the cytoplasm. Construction of the Ribosome: Exportation of RNA molecules synthesized in the nucleus to the cytosol. Ribosomal protein synthesis (of the 60 & 40 s subunits) occurs in the cytosol and are imported back into the nucleus. 

There are various legislations and policies which are put to ensure that the standards of equal opportunities are met. Some of these legislations include - Employment equality regulations act 2006, which prohibits discrimination, victimization, and harassment on the grounds of age and gender in the areas of employment and areas which provide vocational training.

The pharmaceutical industry has very few effective antibiotics left which can deal with MRSA and the proposed strategy to deal with its advance is to improve hospital and care home cleanliness and to keep researching new antibiotic formulae. This will be successful in the short term, but it is difficult to know how long scientists can keep this up.

2. Elodea as an aquatic plant sequesters carbon from the water by the process of photosynthesis. Carbon sequestration by elodea in aquatic ecosystems helps to increase the pH level of the water in which it is found. This

The knowledge of human development replicates the density and uniqueness of each individual and their experiences. The concept of human development is firmly rooted in different theories as well as researchers that are highly focused on efficiently understanding the behavioral patterns of humans (Kail and Cavanaugh 3).

Later on, it was discovered that this principle was evident in DNA. Further discoveries showed that shreds of naked DNA can be accepted by natural bacteria within their environment. Furthermore, the dead bacteria of different species or the same can act as parent

Entropy refers to the degree of randomness in a biological system. Kinetic energy is a form of energy and is the energy of movement, while potential energy is the energy that is stored in a physical system. The first law of thermodynamics states that energy is constant and can never be created or destroyed. It can be transformed from one form to another.

While the normal life span of a normal red blood cell is 120 days, sickle cells die within 10-20 days. The bone marrow of individuals suffering from sickle cell anemia cannot produce red blood cells fast enough to meet the bodys demand. Sickle cell anemia is an inherited

Barbara McClintock used a series of microscopic analyses in demonstrating fundamental genetic ideas. Among the ideas demonstrated by Barbara includes the notion of genetic recombination, which occurs through crossing-over during the process of meiosis (Lynch, Jay, and Derek 23). This provides a mechanism by which chromosomes exchange information.

An endospore stain was performed and resulted positive. Therefore the unknown could fall into one of the following Genuses: Amphibacillus, Bacillus, Clostridium, Corynebacterium. Subsequently, the Catalase test was selected to narrow down the genus possibilities.

Mitosis is generally succeeded immediately by cytokinesis also called cytoplasmic division which divides the nuclei into two cells that contain equal cellular components. The two processes define the mitotic phase of the cell cycle that divides the mother cell into two daughter cells that are identical (Snedden, 1-48). 

In the case of lupus the results of this attack are widespread and involve such things as joint damage, inflammation of tendons and the whole connective tissue system as well as organs . This damage occurs because the body produces

Helicobacter is unacceptable in human health in that it infects individuals with a number of infections. These infections are dangerous and affect the normal processes that occur in the stomach. However, this bacterium has more benefits to the human body. As seen in the paper, bacteria can prevent a lot of diseases such as asthma among children.

I have profound experience in General Biology where I undertook laboratory reports, poster sessions, and various research projects. In addition. I also have experience in Genetics chemistry and Cell biology. Additionally, I have experience in the Biology of Microorganisms where I identified unknown bacteria.

The lecture explained how population ecology studies the dynamics of population and how it is able to measure its impact on the environment and vice versa. The lecture, for example, demonstrated the models and dynamics of population growth and how it affects the quality of life of the inhabitants of a particular location, especially with regard to access to resources and environmental degradation.

ientists to recognize and study the changes that have occurred in the size of human body and brain, diet, locomotion and other aspects of the human evolutionary course that has occurred for the last six million years. The evolution of man has entailed many changes in the way of

Nondirective meditation is based on effortless concentration of breathing or feelings. Researchers use MRI to track brain activity during meditation and compare it with brain activity when people rest. The

An aggregate of 31 chicken specimens were analyzed comprising of Non Halal Chicken and Halal Chicken. In the PCR analysis of DNA samples extracted from the colonies of 10 samples, C. coli was identified from 31 samples (32.26%). This proportion was

Permitting changes based on the provisions of the Native American drug courts may undermine the effectiveness of the American justice system. The Native American drug courts were based on a specific community’s belief in society. The authors further assert that these laws may not be used to judge a person from a different community.

Tilapia was first farmed in Africa before its farming was introduced to the other parts of the world that have tropical climates. It is the third most farmed fish in the entire world. Tilapia are largely farmed in the world because of their high protein content, their rapid growth rate, their large size and also their palatability to human beings.

The phenotype includes body parts such as, tissues, cells, organs, and even behaviors while genotype is purely about alleles and proteins which make up the DNA and RNA of an individual and which are embedded in the genes. They cannot be observed but are known to exist through the in-depth study and analysis of genetics in genetic engineering.   

Enzymes are biological catalysts, that are present in the body to carry out various metabolic activities. They are basically made up of protein molecules which are very sensitive to temperature fluctuations in the surrounding where they accomplish biological reactions. Our daily diet encompasses great quantity of starch. 

Probability defines an event’s chance of occurrence and may be theoretical or experimental. While theoretical probability relies on naturally expected observations, experimental probability is derived from experimental observations. This report seeks to investigate probabilities in genetics and inheritance. The paper concludes that theoretical probability sufficiently predicts the inheritance of genes.  

Leukemia is categorized into chronic or acute leukemia. These categories have some differences and similarities in terms of their symptoms, diagnosis, treatment, and prognosis. In acute leukemia, abnormalities are caused by immature blood cells that are not able to function appropriately. These cells grow rapidly, which ends up preventing the formation of normal or healthy blood cells.

It is essential to state that breast cancer is the second leading cause of cancer deaths in women today (after lung cancer) and is the most common cancer among women. According to the World Health Organization, more than 1.2 million people will be diagnosed with breast cancer this year worldwide (Lynn & Charles, 4).

The author states that as far as deafness is regarded as a disability it is ethical to undertake measures like in vitro genetic screening of human embryo. The understanding that deaf persons are a minority due to their culture and language does not change the argument that in vitro genetic screening of human embryos is ethically right.

Other models were also applied to reveal if consuming healthy food and physical exercises influence the duration of life conjointly. Such factors as race, level of education and age are taken into account. The study revealed

In addition, public health ensures development of social machinery, which ensures an adequate standard of living for every individual in the community for health maintenance (Atrash, & Carpentier, 2012). The

Generally speaking, the investigators went even further and illustrated a database of all glass bottles made in the early 19th century to the viewer as proof of the way in which police investigatory tools could be utilized to date and define/determine where a particular piece of glass originated (Zhu, 2014).
