At the point when the wind transports silt by saltation, little particles are brought about to "bob" or "bounce" by the wind, moving them toward the path the wind is blowing. Essentially, the particles are skiped along the surface once or a few times until they lose energy and additionally lift from the twist, and soon thereafter they rejoin the silt on the ground. It is a type of transport that for the most part prepares little particles, however the size increments with expanded wind speed.

Explanation:
Behaviors that are determined by genes and that give an organism increased reproductive success usually become common in a
species due to <u> </u><u>evolution by natural selection,</u>
In<u> evolution by natural selection, </u>the following must occur
- reproduction
- the inheritance of specific traits from parent to offspring- heredity
- variations in the number of offspring each individual produces
- variations in physical characteristics
Further Explanation:
Sequences of DNA make up genes which can have different forms called alleles. DNA, which makes up the genotype, is transcribed into mRNA and later translated into amino acids which are linked together by rRNA to form proteins which make up the phenotype of an organism.
During reproduction other events, such as crossing over during mitosis and meiosis, mutations lead to increases in genetic variation. This variation refers to the genetic characteristics present within a species. Mutations may be either beneficial or deleterious; they are maintained within cells, as they form new traits called alleles. Beneficial trails may confer traits that increase the fitness of a species, along with ensuring survival by conferring a protective advantage- these phenotypic differences between organisms are called adaptations.
This is called natural selection- an evolutionary mechanism which changes the inheritance frequencies of these beneficial alleles over several generations of offspring. These offspring are said to develop adaptations which ensure their survival, the alleles for which become more stable within a population over time.

Unlike endocrine glands, exocrine gland RELEASE SECRETIONS OUTSIDE OF THE BODY.
There are two types of glands in the body, the endocrine and the exocrine glands. The endocrine glands are ductless glands and their secretions are normally released directly into the blood stream. The exocrine glands on the other hand have ducts, through which their secretions are release outside the body. An example of this is the sweat gland.
<span>Adult stem cells are the body’s toolbox, called into action by normal wear and tear on the body, and when serious damage or disease attack. Researchers believe that adult stem cells also have the potential, as yet untapped, to be tools in medicine. Scientists and physicians are working towards being able to treat patients with their own stem cells, or with banked donor stem cells that match them genetically.</span>
