1 Why does the variety of foods available to us today make it more difficult rather than easier to plan nutritious diets?

It doesn't make it more difficult. It makes it easier. However, it also makes it easier to get good tasting, satisfying meals for minimal cost, time, and effort and that has resulted in an increase in poor eating habits and obesity.


How do seeds of cherry disperse?

Another mechanism by which seeds are dispersed by animals involves their encasement in a fleshy, edible fruit. Such fruits are often brightly colored, have pleasant odors, and are nutritious and attractive to herbivorous (plant-eating) animals. These animals eat the fruit, seeds and all. After the fruit passes through the animal's digestive system, the seeds are dispersed at some distance from the parent plant.The seeds of many plants with this sort of animal-dispersal strategy actually require passage through the gut of an animal before they will germinate. Some familiar examples of species that develop animal-dispersed fruits include the cherries, tomatoes, and watermelon.


How do you become fat?

There are three common ways people gain weight:Significant overeating is likely to lead to weight gain.A lack of exercise may do the same.Some drugs have weight gain as a side effect.None of these are generally healthy. If you are trying to gain weight, eat more, but make sure that you eat whole foods (unprocessed foods where the nutrients have not been drastically reduced). Ironically, many people who overeat also have deficiencies in certain nutrients because they do not eat a balanced diet of whole foods.Regardless of whether you are trying to lose, gain, or maintain weight, an adult or teen should always have a minimum of 4 servings of vegetables, 4 servings of fruits, 6 servings of grain, and 3 servings of milk or other, relatively unprocessed dairy foods (ice cream, sadly, has almost none of the original product's health value).Healthy foods to gain weight (as long as they are unprocessed) include:Nuts, especially almondsFruits, especially avocados (yes, they're fruit!) which are high in healthy fatsAny whole grain products such as bread, black rice, or quinoa (try not to have too much breakfast cereal, as there may be health risks to this)There are of course many others, but you can find those out on your own easily enough.Cooking is your friend! Many nutritious foods that would be unappetizing on their own are quite delicious in a recipe. Look for healthy recipes online. It is also easier to consume more calories quickly and enjoyably in a recipe than it would be to eat the raw materials.Don't eat too much salt, simple sugar, or saturated fat, all of which have health consequences. Complex carbohydrates (generally referred to simply as "Carbohydrates" on a Nutrition label) are good.Finally, have many snacks and smaller meals. The breaks between eating ensure that you aren't too full to eat.Using these tips, you will have a reasonably healthy diet and can expect to gain weight at a healthy pace.Or gain lots and lots and lots and lots and lots and lots and lots and lots and lots and lots and lots and lots and lots and lots and lots and lots and lots and lots and lots and lots and lots of weight like tens of thousands of tons so be lazy eat lots of fat foods like cakes, ice cream, cookies, chips, and lots and lots and lots and lots and lots and lots and lots and lots and lots and lots of candy.


What problems are caused by lack of clean water?

The lack of access to clean water can lead to numerous problems, affecting individuals, communities, and overall public health. Here are some common issues caused by the scarcity or contamination of clean water: Increased risk of waterborne diseases: Insufficient access to clean water can result in the spread of waterborne diseases such as diarrhea, cholera, typhoid fever, and hepatitis A. Contaminated water sources provide a breeding ground for bacteria, viruses, parasites, and other pathogens, leading to widespread illnesses and even fatalities, particularly among vulnerable populations like children and the elderly. Sanitation challenges: Inadequate clean water availability hinders proper sanitation practices, including handwashing, hygiene, and waste management. This can contribute to the spread of diseases and poor hygiene conditions, further exacerbating health risks and impacting overall well-being. Impaired nutrition and health: Lack of clean water affects food production, agricultural practices, and access to nutritious food. Water scarcity can limit irrigation for crops and livestock, reducing food availability and negatively impacting nutrition. Insufficient clean water for drinking and cooking can also compromise the quality and safety of food, leading to health issues. Economic burdens: Communities facing water scarcity or relying on contaminated water often endure economic burdens. The need to travel long distances to fetch water or purchase it at high costs can strain household budgets and hinder economic development. Additionally, health issues resulting from waterborne diseases can lead to increased medical expenses and reduced productivity. Environmental impact: The lack of clean water can disrupt ecosystems, affect biodiversity, and harm aquatic life. Water pollution from untreated wastewater and industrial contaminants further degrades water quality, negatively impacting ecosystems and the overall environment. Social inequalities and conflicts: Unequal access to clean water can exacerbate social inequalities and create conflicts over limited water resources. Disadvantaged communities, particularly in marginalized areas or regions affected by drought or political instability, are disproportionately affected, leading to social unrest and tensions. Addressing the challenges of water scarcity and contamination requires efforts to improve infrastructure, promote sustainable water management, invest in sanitation and hygiene practices, and ensure equitable access to clean water for all.


Contributions of Sumerian?

MathematicsThe Sumerian System, called "sexagesimal", combined a mundane 10...with a "celestial" 6, to obtain the base figure 60. This system is in someways superior to our present one, and much superior to later Greek andRoman systems. It enabled Sumerians to divide into fractions and multiplyinto the million, to calculate roots or raise numbers several powers.This was not only the first known mathematical system, but also one thatgave us... the "place" concept: Just as, (in the decimal system), 2 can be2 or 20 or 200, depending on the digits place, so could a Sumerian 2mean 2, or 120 (2 x 60), and so on, depending on the place.The 360 degree circle, the foot and its 12 inches, and the "dozen" asa unit, are but a few examples of the vestiges of Sumerian Mathematics,still evident in our daily lives.Their achievements in Astronomy, the establishment of a calendar, andsimilar mathematical feats will come up later.The Sumerians are credited with two technological breakthroughs...that made it possible to combine lightness with tensile strength, forall clay products: "reinforcing and firing" .Modern architects... have discovered that reinforced concrete, anextremely strong building material, can be created by pouring cementinto molds... containing iron rods; long ago, the Sumerians gave theirbricks great strength... by mixing the wet clay with chopped reedsor straw.he Sumerians used petroleum products, not only as fuels, but alsoas road building materials for water-proofing, chalking, painting, cementingand molding... there was a "mound of bitumen", in Ur. Forbes shows...that the Sumerian language... had terms for every genus, and variant ofbituminous substances found in Mesopotamia.For example, the most common word for petroleum, "Naphta", derivesfrom "Napatu", "stones that flare up".The Sumerian use of petroleum products, was also basic to anadvanced chemistry and alchemy. The high level of Sumerian knowledgein the variety of paints and pigments used... and such processes... asglazing, as well as the remarkable artificial production... of semi-preciousstones, including a substitute for Lapis Lazuli.Bitumens... were also used in Sumerian Medicine, another fieldwhere the standards were impressively high. Hundreds of Akkadiantexts... that have been found, employ Sumerian Medical terms andphrases extensively, pointing to the Sumerian origin... of all Mesopotamia medicine. They were very advanced in cloning.
