<span>The </span>second law of thermodynamics<span> states that the total entropy cannot decrease, </span>only<span> increase. This is why </span>living organisms<span> give off thermal energy: they lower their entropy, but the total entropy increases.</span>
Our genes can be affected by the environment and change the way our traits are displayed, called the phenotype. However, changes in phenotype have an underlying genotypic source. Epigenetics or epigenetic changes are changes in the way traits are expressed as an effect of the environment (i.e. food we ate, chemicals in the body, environmental stresses), without changes in the DNA. Simply put, in epigenetics, some parts of the DNA are turned on or off in response to environmental conditions.
Answer;
-Pure chemical substance and element
Explanation;
-Pure substances are substances that are made of only one type of atom or molecule.A pure substance can be either an element or a compound, but the composition of a pure substance doesn’t vary.
-An element is a pure substance that cannot be broken down into different types of substances by chemical means. All elements are pure substances. An element is composed of a single kind of atom. An atom is the smallest particle of an element that still has all the properties of the element.
-Tungsten is an element and therefore a pure substance.
Answer: Chromosome
The polynucleotide DNA strands are wrapped on circular proteins called histones which then are condensed into a structure called chromosome.
Let me try...
How about, grass, moose(moose eats grass), black fly(when moose dies it's eaten by fly), fish(fish can catch flies sometimes), and then Osprey(birds eat fish).
The second one... How about, grass, deer(deer eats grass), then wolf(eats deer), the mosquito(sucks wolf's blood), I don't know the dragon fly though
HOPE THAT HELPED SOMEWHAT :)
