Variable Exposure of Leaves under Sun and Shade 2
Abstract
We tested two different populations of leaves from the oak tree. We measured the leaf area and perimeter of shaded leaves and sun-exposed leaves from a number of samples from the same tree. We found that there were a number key differences between the two groups with shaded leaves being larger than the leaves exposed to sun. The leaves also appeared bigger. Statistics were performed and found that there was statistically significant variance between the two groups. The results are discussed in terms of how Continue reading...

Assignment #11. Based on what you already know about photosynthesis, develop a testable hypothesis to explain the influence of an increase in light intensity on the photosynthetic rate in tomato leaves. ( hint: make sure your hypothesis is specific enough such that the results of your experiment will support it or disprove it. For example a BAD hypothesis would be: Increased light allows the plant to grow larger. You are not testing the growth of the plant in this experiment .)Answer
Basing on the experiment, the increase of light intensity increases the photosynthetic rate. It is evident that this rise Continue reading...

One of the vital parts of Integrated Pest Management is crop scouting. The IPM makes use of field-specific data and enhanced decision-making to offer protection to crops production and quality while reducing the risks related to the use of pesticides. Scouting offers field-specific data on crop injury and pest pressure. The data are significant to the proper selection and use of procedures for pest management. Even though scouting is often considered as a technique in which approvals for in-season rescue managements are conducted, scouting can likewise be utilized to recognize whether replanting is apt and to suggest pest management Continue reading...

Executive Summary

Tobacco was one of the most profitable businesses in the US during the 1950s and 1960s. However, after the discovery was made as regards the carcinogenic effect of tobacco and addictive substance, the government introduced an array of policies to curb tobacco sales and marketing, which reduced the total tobacco consumption in the world. However, tobacco companies continue to make money.
Altria, which is the largest tobacco manufacturer, is diversifying its portfolio. It knows that selling only cigarette will not be a good business strategy in the long run. It is diversifying into smokeless tobacco, e-cigarette and cigars. It Continue reading...

The golden ratio is a number, represented by the symbol φ, such that between φ and 1, along with 1 and 1- φ, the ratio is the same. It is an irrational number explicitly created by the formula 1+√52 = 1.618033988 (Beck and Geoghegan). Like fractals, the golden ratio unifies several different areas of mathematics together. Interestingly enough, it is also found in many places in nature. The golden ratio has been detected even at the quantum level, where liked magnetic atoms appear to vibrate at frequencies described by φ.
The Fibonacci sequence is a number sequence, essentially 1,1,2,3,5, Continue reading...

This paper presents a calendar for a commercial peach tree orchard crop. A peach plantation can be a profitable venture or a budgetary disappointment, depending to an extensive degree on how well the grower has arranged ahead in picking the location and cultivars and arranging the fundamental social operations.

The most hectic periods of the year would be as follows:

Late February up to March – Pruning
Late April – Thinning
Middle of July until August – Harvest
Peaches will start bearing a crop as it reaches its third year.
Peaches will reach its full production on its fifth year.

This paper presents some of the methods to control pests.

A. Borer
Borers seek stressed trees through the strong smell that the water stress gives off. Water pressure brings about a higher percentage of ethanol production and anaerobic glycolysis. Ethanol extracts plant oils and boosts the strength of the smell. Control of peach tree borer can be difficult since the larvae are not fully available underneath the tree bark. Effective means of controlling borers include preventive insecticides that target the eggs or the larval stage. There are two forms of chemicals that can kill borers – trunk insecticides and systemic insecticides (extension.entm.purdue.edu). Trunk insecticides are made up of long lasting Continue reading...

In a study, Kumar et al. noted that the rising level of CO2 affects the plants, which can work as an alternative source of energy (501). They hypothesized that plants with elevated level of photosynthesis with elevated levels of CO2 could help in reducing the burden on potential biofuel tree species. In this regard, they studied the plant Jatropha curcas.
Researchers found that Jatropha curcas can grow in numerous conditions of soil with least necessities of growth and development. Moreover, it is one of the non-edible oil producing plants making it useful in biofuel production. So, they studied the Continue reading...

Diffusion, osmosis, and functional significance of biological membranes

Abstract
Diffusion is the process in which substances move from an area of higher concentration to an area of lower concentration. If a semipermeable membrane is involved in this movement then this process is known as Osmosis. Semipermeable membrane is any biological membrane in the body that is selectively permeable. These membranes protect the cell from external environment. These are also involved in the movement of molecules in and out of the cell. This movement of molecules result in the differences in concentration until an equilibrium is established. In this research, we have done experiments on Elodea cells to Continue reading...

Abstract

Studies have shown that soil and atmospheric nitrogen concentrations affect the growth potential of fern species across a wide variety of ecosystems. This study evaluates whether high ammonium nitrate concentrations will decrease fern spore growth.
Keywords: ferns, nitrogen, NH4NO3, diversity, growth

Introduction:

Ferns are types of plants that are found in moist environments. They are vascular, seedless plants, which are classified as pteridophyte. Like all vascular plants, they have a specific life cycle called alternation of generations, characterized by alternating diploid saprophytic and haploid gamtophytic phases. A diploid sporophyte phase produces haploid spores by meiosis, and a haploid gametophyte phase Continue reading...

Question 1

The measures of central tendency consist of the mean, median and mode and they act as a representative of the entire sample. The mean of a set of numbers is calculated by summing the individual’s terms of that set and dividing by the count of the set. The median is obtained by arranging the values in ascending or descending order and obtaining the middle value. The mode represents the number that occurs most in any set of data. In the case of grouped frequencies, then the mode is represented by the group with the highest frequency.

Question 2

The mean Continue reading...

The sound of guitar strumming accompanied by a husky male voice filled the cold night air. I was roused from sleep by that sound, but I did not mind. “Country road, take me home; to the place, where I belong. West Virginia, mountain momma, take me home country road” the voice sang. My mind was still drowsy from sleep but I could not help smiling. I know it was my grandfather singing his favorite song. I climbed out of my bed and ran as fast as I could towards the direction of the melody. And there I found him, Continue reading...
