A non random influence affecting who survives or reproduces
is selective pressure. A selective pressure is considered to be a phenomenon in
which behaviors of the living organisms are being driven to evolution and the
natural selection in which they are also divided in to two types.
There are cold fronts, warm fronts, stationary fronts, and occluded fronts.<span />
People sleep (usually) at night, and dogs and cats doze pretty much whenever they can. But how about other living things, like plants? Whether or not those tulips turn in at the end of the day depends on whom you ask—and how you define sleep.
Plants don’t have a central nervous system, which is an essential regulator of sleep in humans. But they do tune themselves to a 24-hour circadian rhythm, just like you. And they do shut down certain processes, like photosynthesis, when the sun goes down, shifting their focus instead to delivering glucose (sugar) throughout the plant. Some plants, including the aptly named morning glory, also close their blooms when the sun goes down.
Sunlight is a key trigger for humans to know what time to sleep and when to be awake. And the same is true of plants. While light and dark tell your body when to produce the hormone melatonin, which cues your body to feel sleepy, light and dark triggers tell plants when to produce the hormone auxin, which controls growth and development.
Plants may not be able to get up and hunt for food (or grocery shop, or call for takeout, for that matter!), but they do move in small ways to maximize their exposure to energy-giving sunlight. During the day, they soak up the sun in order to make energy through photosynthesis, a plant’s version of eating. Then, at night, they turn their attention to metabolizing the energy that they’ve taken in and using it to grow. So maybe you should be saying “goodnight” to your garden when you turn out the lights! hope this helps
Answer:
According to the Acceptable Macronutrient Distribution Ranges (AMDR), what percentage of total calories should come from carbohydrate?
<u>The answer is</u> "45 to 65 percent"
Explanation:
<u>Carbohydrates</u>:
Carbohydrates are grouped into 3 classes: Monosaccharides, Oligosaccharides and Polysaccharides. Carbohydrates are found in living organisms as they are also known as sugars. They are are the most abundant bio-molecules belonging to class of organic compounds. The breakdown of carbohydrates supplies the principal part of the energy that every organism needs for various important processes. Carbohydrate foods are an important source of fiber and other nutrients.
<u>Acceptable Macronutrient Distribution Range:</u>
Acceptable Macronutrient Distribution Range is the predetermined range of intake for a particular energy source in our diet that is associated with overall health and reduce the risk of chronic disease with the aim of making the intake supply essential nutrients which are important in metabolism, growth, and many other functions. If an individual consumed in excess of Acceptable Macronutrient Distribution Ranges, it raises concerns over a potential increase in the risk of chronic diseases.
