The cells in the two classes of organisms (plants and animals) possess a number of similarities and differences. For the cell to perform its tasks it undergoes a number of processes. First, there is the process of forming the new cell which is called cell division. This forms two new cells called daughter cells.
The results show that lactase activity is low when temperature is low at 00C but improves with increasing temperature up to 370C after which activity drops sharply. Low activity at low temperature is due to low activation energy exhibited by

Since birds harbour the virus that causes the flu, then they can be referred to as disease reservoirs (Banks et-al 39). Asia is one of the most populated continent in the world and hence people live in close proximity.
This does not make the essay weak; however, it does indicate that no primary research was performed in order to write it.
Likewise, in terms of what was learned, the discussion provided a helpful starting point in understanding how bacteria spreads
In this experiment we have conducted the solid-phase sandwich ELISA which allows for detection and quantification of the antigen (Stryer et al, 2002). Here, the antibody is immobilized in wells and antigens are allowed to react with it. After
Among the integrated management programs and policies legislated so as address overharvesting of the oceans and farming fish in aquaculture settings include promoting a social attitude against the use of hormones frequently
14) further explains that the menstrual cycle consists of three phases based on events that take places either in the ovary (ovarian cycle) or the uterus (uterine cycle). The former involves follicular phase, ovulation and luteal phase (McNamara, 2014). The latter involves
Along side the experiment, a control experiment was done by using grass and allowing it to grow in normal conditions without using salt. This was necessary as it would help in comparing the effects of salt on the growth of grass.
Later on, it became very well known, that this virus is passed from one person to another through body fluids such as blood, vaginal fluid, semen, other body fluids containing blood and, sexual contact. As a result to incurability, Canada has made important
These processes are divisible into three categories. These are active transport, passive transport and vesicular transport. As shown in Fig 1, the cell membrane is the outer layer of the cell. It is the medium through which
The earwigs utilize the “skin wings” order name; because of the membranous wings located under the short forewings (Fisher, 2006).
Earwig insects are hemimetabolous, hence they experience incomplete metamorphosis which develops between 4 and 6 molts series.
mple evidence to show that human activities, in particular, burning of fossil fuels, have resulted in increased amounts of greenhouse gases and carbon dioxide in the atmosphere. The industrial revolution is another primary cause that has led to the increased greenhouse gases
In most cases, illumination technique by bright field light is made possible by applying stains to improve contrast by absorption by specimens.
Tissue sample removed from its immediate source should be fixated with fixing
These fat substitutes may be categorized in three major classes including: Carbohydrate-based fat substitutes, Proteins and microparticulated proteins and Fat-based fat substitutes (AHA, 2013). Research suggests the positive impacts of fat
The dependent variable is the effect that cattle have been confirmed to be the main reservoir for the growth of the bacterium. The hypothesis of the study is that the danger of E.coli infection is more
The process of creating designer baby has often questioned because of its unstable moral platform. The processes involved are not natural. Genetic engineering of babies comes with some challenges. Some of its shortcomings are: - Division of the socioeconomic strata, Designer babies intensify the superficiality in the society, not a guaranteed process and it is not an ordinary course of life.

This is useful when considering pathogens that have and rely on the ability to live within the hostile environment of the phagosome which may rely on the blockage of these markers for their survival within the cell. The use of Mycobacterium bovis here illustrates the
However, based on ideas gleaned from several reputable references, it remains inconclusive whether hsp70 and hsp60 indeed inhibit the aging process.
Hsp70 and hsp60 are molecular chaperones, or “abundant,
Site one is an agricultural area. Water from this site has high nitrate and nitrite concentrations due to agricultural fertilizers. In addition, it has low transparency due to erosion, average conductivity due to the presence of dissolved nitrate
The flower is commonly referred to as primrose. The lab practical was done using the pin and thrum dimorphic flowers of the flower species. It was initiated to study the flower parts in terms of their structure and
Some bacteria have a mutation that makes them possible to survive the penicillin. Moreover, the administration of the penicillin changes the environment in which the bacteria reside. The bacteria with resistance genes will survive this new environment. The resistance genes pass over to several generations due to natural selection.
Thereafter, sporadic exams were carried out on these men to establish the impact of syphilis on their bodies. The test subjects were deceived they were being treated for ‘bad blood’ a local term which was commonly used to imply
No less than 3 new forms-Rodhocetus, Ambulocetus and Pakicetus-have been discovered to fill the missing gaps between the present day whales and their terrestrial predecessors-mesonychid carnivores that existed 60 million years ago in
On the other hand, other people refer to theology in an attempt to explain the intricacies of human body functioning. Nonetheless, the four attached readings bring out an interesting aspect in the biology of the functioning of human being in health and in
Though I had read some few documents addressing biology, I did not know the acceptable or scientific definition of biology or any biological terms. As such, before joining the biology class I defined biology as a science subject that
The source of infecting microorganisms generates the pathogens that infect the susceptible host through certain means of transmission that might involve fluid transmission, contamination or even direct contact. Therefore, an infection can be prevented by eliminating at least one of the three elements.
During those times, people would consult herbalist for advice concerning certain health issue. The knowledge about natural cures was passed down from generations to generations. Numerous remedies to health
of the neighborhood and passed by my Aunt Susie’s house to let her know that I might get back home late so she could tell my parents who were not around yet at the time. Jay only realized that his watch was missing an hour after we left the cinema place.
This is happening at an unprecedented rate as compared to genetic evolution. This happens as human creates own environment such as improved diet (Palca 1). The other human characteristic is maintenance of harmful mutations in the environment. These include the
Coyne also overemphasizes on biogeographical things other than creationist approaches. The fact that fossil remains are spread in the world raises a lot of questions and credibility to this theory. In other words, fossils remain in a particular area meaning that evolution only took place in a particular area.
Minerals are an important part of our body cells and provide energy for the accomplishment of various functions. We get minerals from the food we take in. lack of minerals results in various diseases. For example, Calcium deficiency causes osteoporosis. Zinc deficiency causes skin changes, breast cancer, and hormonal imbalances.
Scientists have carried out various researches to find out the genes carried by Y chromosome so that the difference between the molecular biology of males and females can be elaborated. Scientists have also studied the evolutionary origin of the Y
After a short period of delay, the left ventricle contracts forcing blood through an opening that leads blood to the largest artery in the body referred to as the aorta. Special valves known as atrio-ventricular valves then close and prevent the flowing back
Regarding the fairness of the test, if all variables have been carefully measured and all other extraneous variables eliminated, the test is naturally fair. However, there also seems to be a need for the performance of the new
The difference between two readings could be due to many reasons. The high value in the second test can be attributed to inadequate wiping of the pipette, improper mixing or uneven distribution in counting chamber.
