Extract of sample "Highschool Biology Questions"

Download file to see previous pages The theme of Evolution is responsible for the presence of the diverse range of species present on earth. It is further propagated through the processes of adaptation and breeding as cited by Roberts. Bees are naturally interdependent on other aspects of the environment, both biotic and abiotic to survive, thus demonstrating the theme of Interdependence.

2. The process of cytokinesis occurs immediately after mitosis in both animal and plant cells. This process and its outcome show certain similarities and differences in both animal and plant cells. Cytokinesis is similar in plant and animal cells because it results in the production of two daughter cells resembling the parent cell in all aspects (p 366). Plant cytokinesis, on the other hand, differs from that of animal cells by forming cell plates that separate the cytoplasm of the two daughter cells along the equator of the spindle instead of a contractile ring as is the case in animal cells (Roberts).

3. Eukaryotes have their nucleus and other internal organelles enclosed within a membrane as opposed to that of prokaryotes. This structural advantage makes eukaryotes capable to metabolize their food more efficiently than prokaryotes. In both cells, the use of flagella is a paramount survival adaptation. The flagella are used as the main tool of locomotion in both the prokaryotes and eukaryotes (p 35). In addition to the use of flagella in locomotion, prokaryotes use it to protect themselves against adversaries by lashing it out. This use is replaced by the employment of more complex and well-developed organs in eukaryotes (p 37). The cytoplasm in prokaryotes is served as one of the many vital functions served by the cytoskeleton of eukaryotes. These two features serve to bring about the transportation of substances within each of the two cell types.

4. The end products of mitosis and meiosis differ in some very important ways. Mitosis occurs in one cell division whereas meiosis occurs in two. ...Download file to see next pagesRead More

Questions about Fruits Biology

...?Topic - Fruits Why are some fruits sweet and some sour, whereas others have no specific taste? Every fruit has a different, taste, texture and colour.The appeal and taste of fruits are depended on the chemical composition of the fruit. There are fruits which are sweet, sour and those with no specific taste. The sweetness of a fruit depends on the chemical structure of it. The sweet taste of the fruits is attributed by the presence of fructose contained in it. In general, fruits are comprised of, fructose, cellulose, vitamins, starch and acids. These entire compounds combine to give a particular taste to the fruit. Every fruit has a different proportion of these elements and accordingly its taste varies. The fruits which have more...

Biology Questions

... Biology Qn Prokaryotic according to numerous studies undertaken by experts, they contend that, it is the ancestor of eukaryotic cell. This aspect in arguing and intending to present it in a correct and understandable manner, it has generated contrasting theories from both the early and present experts. Structurally, both the eukaryotic and Prokaryotic cells usually bear proven distinctions. The latter has fewer organelles in its structure compared to eukaryotic, which has extra of the same contents in its structure and larger in size. Study theories claim that eukaryotic normally evolved from Prokaryotic, which yielded to the current state of the cells via endosymbiosis process (Virtual Fossil Museum). Prokaryotic initially prior infusion...

Plant Biology questions ---angiosperm questions

...?Plant Biology Questions: Angiosperm Plant Biology Questions: Angiosperm Angiosperms are also referred as flowering plants. They form a significant part of the extended seed group of plants. Alternatively, angiosperms may be considered as plants that are produce sexually through pollination and development of flowers. Some pollination processes are facilitated through the aids of birds and bees among other animals (Wachman, n.d.; 01). Pollination usually creates fruit holding seeds that are used to further the plant generation. Angiosperms have or produce two types of seeds including monocots that have only cotyledon and the dicots with two cotyledons. Cotyledons are tiny structures found in seed and they form leaves during their later...

Highschool Dropouts

...? High School Dropout The US high school dropout epidemic paints a grim picture of the country’s educational future.Each year, many of the students who enroll in the elementary level fail to graduate from high school. What is even more worrying is the trend where many of the students abandon school with less than two years to graduation. Various studies have indicated approximately a third of all public high school students do not see out their high school years where about a half of this group is from the Hispanics, Native Americans and African American communities. This recurrent problem has led to various initiatives to explore extend of the crisis in addition to finding the reasons and possible solutions to arrest the dropout... High...

Short Biology Questions

... Short Biology Questions List 2 events that occurred 65 million years ago and their effect on the history of life on earth. a. Asteroid or comet and earth collision Numerous palaeontologists to date contend that Asteroid/comet and earth collision contributed immensely to the dinosaurs’ extinction besides other life forms. Dinosaurs comprised the greatest and fearsome reptiles that existed on the planet approximately 65 Million years ago (Benton 64). 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 both the animal and plant life...

Cell biology questions

Therefore it can be concluded with lots of confidence that absorption of an intensive color during this process is the primary reason as to why molecule mobility is reduced between membranes. This aspect is used in a number of ways one of them being is to characterize mobility of proteins and lipids in the body whenever need may be or examination of cytoskeletal dynamics.
Proteins take several steps to cross from endoplasmic reticulum, where they are produced and processed in readiness to transport to plasma membrane. You find that proteins are synthesized by the Golgi processes in the endoplasmic reticulum before they are sent to any cell. Studies have shown that prior to the proteins going through the endoplasmic reticulum t...

...Biology Questions Biology Questions Darwin’s Theory of Evolution According to Darwin’s theory of evolution, everyliving organism shares a common ancestor. It is due to evolution and adaptability that made the one organism different from the other. In an example Charles Darwin described that Giraffes, Zebras and horses have a common family background, it s due to evolution that made the giraffes different from the zebras and horses. Like, long ago, the grass become short due to a weather condition and horses began to eat leaves from the tress that made their neck long. The births after evolution are with long necks.

Biology Data-based Questions

Potassium or K and Calcium or Ca has shown greater Mean Residence Time in rainforest chaparral when compared to temperate forests whereas Phosphorus or P demonstrates maximum variance in Mean Residence Time.

In general, plant productivity and Mean Residence Time are such that one increases whilst the other decreases. In subarctic regions, there is low plant productivity and greater Mean Residence Time.

In tropical forests, the mean residence time of nutrients is influenced by higher temperatures than in subarctic forests. Therefore, there is a vast difference in the MRT of nutrients pertaining to the tropical rainforest and the subarctic forest.

Nuclear fission weapons tests in 1961 released radioa...
