Answer:

In human nutrition, the glycemic index provides a physiological classification of foods useful in developing nutritional programs for patients with insulin resistance or noninsulin-dependent diabetes. Lacking effective application of glycemic response and glycemic index data of horse feeds, the focus has been instead on restricting starch and simple sugar intake in horses. There is currently a trend in the horse feed industry to manufacture low or controlled starch feeds, with claims of reducing the risk of grain-associated metabolic disorders; however, lack of reports elucidating the effect of various starch intakes on relevant outcomes leaves questions regarding exact concentrations of dietary starch for horses that may be considered “low.” Sufficient research supports limiting starch to no more than 2 g starch/kg BW/meal in order to avoid overload to the hind gut, but more research is needed to link minimum meal concentrations of starch for avoidance of other conditions that have been associated with dietary starch (e.g., gastric ulcer syndrome or equine metabolic syndrome). Recent work suggests that starch intake should be limited to <1 g starch/kg BW/meal in order to reduce risk of equine gastric ulcer syndrome (Luthersson et al 2009). An examination of glycemic and insulinemic responses to increasing starch intake of a mixed grain concentrate indicated that feeding <1.1 g starch/kg BW/meal resulted in lower glycemic and insulinemic responses, compared to meals up to 2 g starch/kg BW (Vervuert et al 2009b). A similar study in this laboratory examined glycemic responses to intakes of oat grain NSC (calculated as ESC + starch) ranging from 0.6 to 2.0 g/kg BW (Hoffman et al 2009). The glycemic response, calculated as the incremental area under the curve (AUC), plotted against NSC intake indicated a threshold of glycemic sensitivity (i.e. the inflection point, or knot) after which higher NSC intakes produced equally high AUC, at as little as 0.3 g NSC/kg BW/meal (Hoffman et al 2009).

List Characteristics of ALL LIVING THINGS <br>​
nataly862011 [7]

Cellular Composition

Cells are the building blocks to life. From single-celled organisms such as bacteria to multicellular organisms such as human beings, all living things are composed of cells. If you look at the cells of two organisms that are very different, such as a whale and a mouse, it may be difficult to tell them apart under a microscope. Both eukaryotic and prokaryotic organisms are living things.

Growth and Change

Living things grow and change on a daily basis, but also over many generations. The largest redwood trees began as tiny seeds that grew a little more each day. But redwood trees have also adapted to their environment over millions of years, making them resistant to wildfires and tree rot. Redwoods, like all living things, are capable of growing and changing in the short term and evolving in the long term.

Genetics and Heredity

Although all living things are different at the genetic level, it doesn’t change the fact that they all carry DNA. This DNA serves as an instruction guide for growth, development and individual traits. It’s present in every cell in the organism’s body and regulates all physical aspects of that organism’s life. Even when an organism is taken from its natural environment, its DNA controls much of its behavior and instincts.

Maintains Homeostasis

Homeostasis is the process in which living things maintain a stable internal environment. Cells keep an organism at a constant temperature by balancing biological substances and chemicals and ridding the body of waste. Homeostasis is necessary for an organism to complete many cellular processes, and losing homeostasis can endanger its life. No matter how big, small, simple, or complex a living thing is, its cells are constantly working to keep it in homeostasis.

Metabolism

Fungi process energy from dead leaves, sharks receive energy from eating smaller fish, and flowers create energy through photosynthesis. All living things, also known as biotic factors in an ecosystem, require energy to survive. Heterotrophs, including carnivores, herbivores, omnivores, and decomposers, find food from other organisms. Autotrophs, such as phytoplankton and iron bacteria, make their own food. But all of these organisms use sustenance to create energy through chemical reactions, which maintain nutrition and health.

Movement

You may be surprised to hear that all living things can move – especially plants. But it’s true! Plants can rotate their leaves toward the sun, close flower petals and bend their stems as needed. Animals can move their location quickly, in the case of a cheetah, or slowly, in the case of a snail. Even coral, which are also living things, can move with ocean currents and move as they grow. Having the ability to move is a key characteristic of life.

Responds to Stimuli

Animals, plants, fungi, bacteria, and all living things are sensitive to their environments. They can react to stimuli, which are changes in their environment, to protect themselves. Environmental stimuli might include temperature changes, smells that indicate a predator is nearby, or noises from distressed offspring. Living things may also respond to pain, hunger, thirst, or discomfort. This sensitivity helps an organism survive in their environments.

Sexual or Asexual Reproduction

One of the most important characteristics of life is an organism’s ability to reproduce. All living things reproduce sexually, with a partner, or asexually, by themselves. Sexual reproduction involves each parent providing half of the genes to the offspring, while asexual parents provide an exact copy of their DNA to their offspring through mitosis. Living things have a prevailing drive for reproduction that keeps them alive long enough to perpetuate their species.

Living Things in Context

You may be able to think of non-living things that fit one or two of these characteristics. Clouds can grow, for example, and dormant volcanoes appear to maintain homeostasis. But unless an object possesses all of the above qualities, it is not alive. Next, see how these living things fit into the context of the classification of living things. You can also see how all living things are divided into these kingdom examples.
