Lesson 5 Answers:

24.) Plants are classified into four major groups: Bryophytes, Pteridophytes, Gymnosperms and lastly the Angiosperms. Bryophytes are the plants that do not have true vascular systems, which consist of the xylem and the phloem. In this group, includes the mosses, liverworts and hornworts. Together, they are considered as land plants that reproduce their own asexually by producing spores. Spores are produced in the ‘sporangium’ (plural sporangia), a bulb-like structure located at the top of the stalk. It can only be seen through the use of high powered microscope. Because they lack vessels that can bring the nutrients from the Continue reading...

Statistical inference

Let’s first examine what it means in statistical terms. Say, for example, we are evaluating employees on parameters such as; sales, customer approval ratings, and manager’s ratings. But, sales are calculated in dollars, customer approval ratings on Likert’s scale, and manager’s ratings have a maximum score of 40. If we don’t convert these ratings into standard scores, we will end up comparing apples to oranges. So, to convert these scores into a standard score, we first subtract mean score from it. Then we divide the remainder by standard deviation. The result is a standard Continue reading...

NUTRITION LABELLING REGULATIONS

The labelling of the nutritional level had been made mandatory in 1990 in the United States of America in all the food products, specially the ones who claims to have additional features in the food product, like, “low carbohydrate” or “calcium rich”. Especially from 2006, special regulation has been set up for trans fatty acids. It is now mandatory to mention the level of trans fatty acids on all the food products, keeping in mind the growing risk of cardiovascular diseases. Though the list of contents is bit different among different countries, but the basic motive remains the same, Continue reading...

Introduction

Obesity and overweight have been classified as global and serious conditions that have an adverse effect on the human health. Obesity and overweight conditions are defined as excessive or abnormal accumulation of fat that may negatively affect health. In adults the obesity and overweight are measured by the body mass index (BMI), which is simple weight-for-height index (WHO, 2014). The BMI is computed by the ratio of the individual's body weight to the square of body height, indicated in Kg/m2 (WHO, 2014). According to W.H.O., (World Health Organisation), a BMI equal or above 25 is considered as overweight while Continue reading...

Harvey requires enough energy to perform. Consequently, he must consume enough calories to meet all his energy needs. The actual requirement for calorie intake depends on one’s level of fitness and bodyweight. In addition, the intensity, frequency, and duration of physical activity also greatly influence one’s actual energy requirement.

Carbohydrates

Given that Harvey’s daily workouts involve high-intensity activities, his calorie intake should comprise of between55 to 70 percent carbohydrates. In this case, 3 grams per pound of body weight would be appropriate. Based on this recommendation, Harvey should consume approximately 480 grams of carbohydrates per day in Continue reading...

An Analysis

An Analysis
Weight Watchers diet started in September 1961 when Jean Nidetch, an overweight woman from Queens, New York, discovered that the most effective keys to weight control are actually "empathy, rapport and mutual understanding." This discovery was made while she was talking to her friends who, like her, had trouble sticking to their diets and were thus gaining weight instead of losing it. What started as a mutual support meeting between her and a few friends grew to be a world-wide weight control organization now commonly called the Weight Watchers. Officially, Weight Watchers International became a company in Continue reading...

Food items such as eggs, vegetable oil, walnut, fish and milk all vary greatly from each other. Do these items still have anything in common? The answer to this question is ‘Yes’. Lipids are the ones arousing a sense of similarity between them.
Lipids are the group of organic compounds like fats, mono-glycerides, di-glycerides, tri-glycerides, fat soluble vitamins (A, D, E and k) and some components of membranes which usually do not react with water but yet they group together. In other words, Lipids may be defined as the molecules containing hydrocarbons and making up the building blocks of Continue reading...

Abstract

Adequate nutrition is required for optimal wound healing. The normal processes that allow the progress of wound healing are disrupted due to nutritional deficiencies. Increased infection rates and decreased wound tensile strength are associated with malnutrition. Chronic on-healing wounds are formed in malnourished patients or individuals. Such patients can develop infections, pressure ulcers, and delayed wound healing. Morbidity and mortality among malnourished patients with chronic wounds constitute a serious clinical concern. Wound healing is considered as a complex process. It is the process of replacing injured tissue with new tissue (produced by the body). Production of new tissue is Continue reading...

Following the story of the use of ethanol to provide warmth in cold environments, this paper presents research on the effect the consumption of ethanol has on an individual’s body temperature. Firstly, the distribution of heat in the body is done by the blood. Through the vasodilatation and vasoconstriction of blood vessels, the body loses and retains head respectively. Given that ethanol enters the bloodstream directly upon consumption, its effects are almost immediate. Its presence in the blood causes the widening of blood vessels due to its vasodilation effect (Eston & Reily, 2013).
This results in an increase in Continue reading...

Systemic Clearance Extended Calculation

Data: Pharmacokinetic parameters: Fraction unbound (fu), 0.5; Clearance by active secretion (CLsec), 2L/h; Fraction reabsorbed (FR), 0.25; Hepatic Extraction Ratio (EH), 0.25.
Q: Total Systemic Clearance (CLtotal) =?
Formula: CLtotal = (F * D) / AUC (RMI Pharmacokinetics, 2014)
Where, F = fraction of dose absorbed (mg), (1 – FR) * (1 – EH ) (RMI Pharmacokinetics, 2014)
AUC = area under the curve (mg/L/h), (Δt /2) * Cf (Summit PK, 2014)
D = single dose (mg), Q * AUC * F (RMI Pharmacokinetics, 2014)

INTRODUCTION

The research capitalizes on the condition of coastal marine environment due to eutrophication (Gray, Shiu-sun Wu and Or). This process of enrichment that is suppose to foster growth to marine and aquatic life is believed to have an adverse effect due to the disturbance that it creates in the marine system. According to the authors, eutrophication facilitates for excessive nutrient absorption of most aquatic plants and microorganism. As a result, it increases the rate of sedimentation that results to hypoxia. When this happens, fishes and other marine life forms do not receive sufficient oxygen. Malabsorption of oxygen stags growth. Continue reading...

- Describe the normal events of fetal development. How does malnutrition impair fetal development?
Normal events of fetal development: Normal events of development of a fetus take place in the inner uterine wall of the mother throughout a gestation. A fertilized egg or zygote moves through fallopian tube and reaches to the uterus.
During 0 to 3-weeks of gestation, the zygote develops into an embryo within a biological pocket or amniotic sac. As the embryo develops, the amniotic sac, filled with fluid gets enlarged, where the fetus floats. This fluid protects the fetus from injury throughout gestation period. Tentacles Continue reading...

Nutrition is an indispensable component of care. It is from food intake that the body obtains the micro and macro nutrients needed to maintain and improve health. Diet is also an area of regulation for the management of chronic diseases such as diabetes. Care plans focused on nutrition necessarily must be individualized to take into account unique needs arising from specific medical conditions, the client’s developmental stage, and cultural preferences. Developing a care plan entails evaluating for nutritional risk, defining the goals of nutrition therapy, identifying interventions and expected outcomes, implementing the interventions, providing education, and promoting safety.
