Bacterial Evolution In the late 19th century‚ diseases led researchers to find treatments to kill the growth of microbes. The outcome of the search was a new kind of medicine which is known as antibiotics. Antibiotics is a variety of substances that control the growth or kill bacteria. Since bacteria is evolving rapidly and resisting antibiotics due to the overuse of the medicine‚ reducing the need and use would help slow down the bacteria from evolving. There are many things that can be done

It is viridans streptococci 13. there was no inhibition of bacterial growth around the P disk. This is indicative of viridans streptococci. this is a collection of streptococci normally found in the oral cavity. 14. B. Type 2 is lactose-positive‚ and type 1 is lactose-negative. 15. C.

Q1. Although being the most centralised zones in a city‚ the central business district and the inner-mixed zone can be compared and contrasted in terms of land use characteristics and functions. Due to their high accessibility‚ land value and centripetal forces‚ these zones share functions that both draw the public and commercial interest into them‚ and create competition for prime land between business and some residential functions. To compare both zones‚ the accessibility of the CBD and the IMZ

If bacterial meningitis is suspected several tests sound be done before beginning treatment. A blood sample should be taken and a complete blood count (CBC) should be performed and a lumbar puncture should also be performed as soon as possible. Laboratory findings The white blood cell count (WBC) should be 5‚000-10‚000 /mm3. Critical values associated WBC are 30‚000 /mm3. Variables that may increase white blood cell count include: Physical activity and stress‚ final months of pregnancy and/or labor

1 The heart is a muscular organ found in all animals with a circulatory system. The heart pumps blood throughout the blood vessels by contractions. Cardiac means “related to the heart”‚ and comes from the Greek. The vertebrate heart is made up of cardiac muscle‚ it’s an involuntary striated muscle tissue found only in this organ‚ and connective tissue. The male’s heart weighs 9-11 ounces‚ and the female’s heart weighs about 11-12 ounces. A person’s blood pressure has major effects on their heart;

Objective of experiment * The objective of the experiment is to assess the effect of different pH conditions on enzyme activity. Hypothesis * I feel the pH affected the enzyme activity to produce product. Prediction * If the pH affected the enzyme activity to produce product‚ then rate of reaction will change. Procedure * The procedure that we followed was to take two test tubes and label one pH2 and one pH10 and incubate 1 ml of each solution for 30 minutes. Then after 30 minutes

Melissa Morales Bios 101 Spring 2013 Demography- Human Life History Introduction Demography is the study of human populations. It studies the size‚ composition and distribution of a population‚ and the process through which a population changes. Demography allows us to track changes over time and to depict how different periods in history change population dynamics. Births‚ deaths‚ migration and emigration‚ jointly produced the change within a population (Biological Science). Demography
