Sargassum Case Study
CHAPTER 1
The Problem and Its Setting
1.1 Introduction Brown algae (Sargassum) are one of the most abundant plant in the Philippines. It is naturally occurring in the seas all over the country. It is mostly caught by fisherman during fishing or it washes off shore. It is usually thrown away since it is often considered useless. Sargassum is one of the most neglected and ignored plant in the Philippines. Unlike other algae, Sargassum is inedible externally, the plant possess insecticidal and pesticidal properties. The plant contains boric acid, a natural acid that does not contain too much chemicals and can kill pests and insects. That is why sargassum is useful in killing pests. Some researchers found out that also has other natural acids that is use to kill pest. But this study will only focus on killing cockroaches using the extract of the plant. Cockroaches belong to the king animalia, Phylum anthropoda, class insecta and order blattaria. Cockroaches carries various bacteria’s, that once intake can destroy the immune system of our body that will result to various diseases, since they are commonly found near waste deposits. This study will be conducted to determine the effectiveness of Sargassum extract as an alternative pesticide for Cockroaches.
1.2 Background of the study Pesticides widely used in agriculture. Plants are composed of chemical substances of which some are not directly beneficial for the growth and development of the organism. These secondary

839 Words | 4 PagesTASK 2 Infectious diseases are the invasion of host organisms, (microbes) which can be invisible to the eyes. The microbes are also known as pathogens. A microbe infects an organism (which is known as the host of the microbe). In a human host, the microorganism causes a disease by either disrupting an important body process or by stimulating the immune system to mount a defensive reaction. The pathogen, interferes with the normal functioning of the host and can lead to chronic wounds, gangrene, loss of an infected limb, and even death.

442 Words | 2 PagesAccording to Harrison Eutrophication is the excessive production of algae and higher plants through the enrichment of waters by nitrogen and phosphorus. Phosphorus in the form of phosphate is the limiting nutrient as the amount of biologically available phosphorus is small in relation to the amount needed for algal growth. Harrison states that sources of nutrients can be discrete, (sewage), or diffuse, (farmland fertilizers).

620 Words | 3 PagesAs a result, plants have adapted ways to protect themselves against their natural predators by implementing “defense mechanisms”. Such adaptations may be structural or chemical, where structural mechanisms are simply parts of plant structural arrangement, such as thorns. Chemical defense mechanisms are more complex, and involve production of retarding chemical compounds and toxins. These volatile compounds are often released when the plant is damaged, and have physical effects on the predator.

Moreover, the reduction of growth due to poor light conditions and dying plants make it difficult for predatory fish to hunt leading to overpopulation. (Chislock, 2013) Eutrophication can be found in many of our water resources such as ponds, estuaries, and bays. One region with high areas with eutrophication is in a lake shared by Kisumu, Kenya and Kampala, Uganda.

They find ways to avoid incest through complex internal warning systems and desert plants have been known to gamble as humans do, even when it means they take on greater risk in the process. (Pennisi) Jahren states that the cholla cactus had an ‘idea’ to grow a spine, (Jahren 64) the process of evolution took millions of years in that case. They exhibit patience and foresight to make up for their rootedness. The fact that plants remain rooted to the ground causes the misconception that there is nothing going on within them.

Algae Growth Lab Report
843 Words | 4 PagesThe purpose of this lab was to test the effect of pollution on algae growth. Through a series of experiments that lasted a month, four of the six hypotheses were proven to be correct or partially correct. The first hypothesis stated that if 0.5 mL of salt was added to algae, then the algae would grow slower than the positive control. This was proven correct, as shown by the difference of the data from the positive control and the container with 0.5 mL of salt in it.
Cesar Chavez Movie Analysis
477 Words | 2 PagesI chose the movie Cesar Chavez because is about an labor organizer and activist man of the civil rights. Scene ---In 1965 many grape farm workers march 300 miles from Delano, California to Sacramento.

Summary: The Top-Down Effects Of Brine Shrimp On Algae
1219 Words | 5 PagesThe brine shrimp were hatched from cysts in seawater and placed in jars, and the algae were contained in large flasks of seawater in various concentrations, for everyone to access. The number of brine shrimp were our independent variable and the algae concentration were our dependent variable. We obtained 6 clean jars for our group in which we created our miniature ecosystems. We labeled each jar with our group name, lab section number, and replicate number. After deciding on what algae concentration we wanted to hold constant in our jars, we calculated the volume of seawater and algae solution required to achieve the desired algae concentration of 50,000 cells/mL and a total volume of 50 mL (C1V1=C2V2).

How Does Acid Rain Affect Plant Growth
1186 Words | 5 PagesIntroduction: In this task I will be researching the effect that acid rain has on the rate of plant growth. Acid rain is any type of precipitation with a high pH, with high levels of nitric acids. The reason why I had chosen this topic was because acid rain seems to have a great effect on the effect of plant growth, and plants play a very important role in our ecosystem. Acid rain is a major problem in our environment when we are not able to neutralize the acidity.
