The graph shows that the respiration rate does increase as the yeast concentration rises‚ but levels off and eventually reached its saturation point‚ or decline‚ which occurs at 8.5g. This decline may occur because there are too many yeast molecules in comparison to the glucose‚ which may lead to yeast cells hindering a collision thus lessening the reaction. The respiration rate increases as more yeast is added because it gives more opportunities for molecular collisions and so the amount of successful

ebullience in pop culture and society‚ but the economy was booming as well. According to Investopedia‚ “Economic growth is an increase in the capacity of an economy to produce goods and services‚ compared from one period of time to another.” There are a variety of ways a country can achieve economic growth: increases in labor force‚ capital‚ natural resources and higher productivity through increased education. During the 1920s‚ America enhanced economic growth by developing its educational system. In

Chemical reactions can happen slowly or fast. The speed of the reaction rate can be changed. Some of the factors that can affect the reaction rate are surface area‚ temperature‚ and concentration and pressure. Surface area is the exposed‚ outer layer of a solid. Increased surface area increases reaction rate because more particles on the surface of a solid come in contact with the particles of another substance. For example‚ if you place a donut stick into water‚ the donut will react slowly with

suicides can be prevented. Policy makers in many countries have tried different preventive measures & engaged in joint projects to lower their suicide rates. Countries like China‚ Japan‚ Singapore‚ Australia & Pakistan have joined the project‚ Strategies to Prevent Suicide (STOPS)‚ in order to lessen their increasing number of suicide. However‚ in trying to prevent the increase in number of suicide deaths and attempts‚ one must know what the leading causes of it are. Suicide rates change over

and wife by legal pledges. There are many types of marriage such as Polygamy‚ monogamy‚ and polyandry. In this essay we will focus on polygamy and show that it has more advantages than disadvantages. First of all‚ polygamy decreases the rate of divorce. Sometimes it’s a necessity when the woman is older or sick or the man is not content with only one wife. When this happens‚ the man will divorce her and look for another woman‚ especially if he is young and expect to have a great life with

Cash based work and the existence of the “hidden economy” is largely documented in the South‚ where the workforce is “characterized by the highest proportion of irregular workers across all sectors” (Destefanis 9).

Enzymes are highly specific and only catalyse one specific chemical reaction‚ speeding up the reaction by lowering the activation energy‚ the energy required to start a chemical reaction (2). At high temperatures and with various mechanical forces or chemical treatments‚ proteins can denature causing it to lose its conformational
