Which of these is an advantage of using natural gas?
It is fairly safe for use in homes.
What natural disasters cause tornadoes?
Tornadoes are a product of severe thunderstorms and are fairly common in the outer rain bands of hurricanes.
Why are humans the only species with prominent navels or umbilical scars?
All placental mammals have a navel. While it is fairly conspicuous in humans, in most mammals it appears only as a thin hairless line.
How does devolution work in biology?
"Devolution" is a misunderstanding. Species evolve over time, as mutations appear and spread and individuals reproduce and die. Evolution tends to produce species that are fairly well adapted to their environment, but they cannot be said to be "better" than any other species. "Devolution" is the idea that species may somehow regress or become more primitive, but any such change is simply another example of regular evolution. Evolution is not graded, so one species cannot be said to be more evolved than another.
Why is natural gas considered as an Eco friendly fuel?
Natural gas doesn't produce a lot of particulate matter (smoke) when it burns. It's also fairly easy to "scrub" to reduce impurities so it doesn't make a lot of sulfur oxides that cause acid rain.
Are C02 bb guns consistent?
Yes they are fairly consistent
What is the term for a persons fairly consistent pattern of acting thinking and feeling?
personallity
What is the difference between deviation and variation?
Deviation = A full change from the Original (depending on what you're deviating from), while Variation = a change of small or fairly insignificant magnitude from the Original.
Is a catbird a endangered species?
The catbird, Dumatella carolinensis, is not an endangered species, but is a fairly common species over its range.
How does an estate work without a will?
The laws of intestacy will apply. The laws are fairly consistent providing for the spouse and children.
What is the one active volacano in antarctica?
There are about 70 volcanoes on the Antarctic continent, and Mt Erebus is fairly consistent in its activity.
What are the main components of Darwin's theory of natural selection?
The modern theory of natural selection is fairly elaborate, and there are no particular chief components. But here goes! 1 An observation: organisms in general produce more offspring than there are parents. So the population of every species has a tendency to increase. 2 Another observation: in practice, populations remain at more or less the same size. There are fluctuations, which are considerable in some species, but behind all this "noise" the "signal" is a constant population size. 3 A deduction from 1 and 2: there is competition (for survival) between individuals of a species. 4 One more observation: among individuals of a species there is variation (= variability). They are not all alike. Although Darwin and Wallace did not know details of genetics, this variation is caused partly by genetic and partly by environmental factors. The modern theory says that it is the genetic variation that matters. 5 A final deduction: it is the individuals that are best adapted to their environment that are most likely to survive and reproduce. Natural selection refers (almost poetically!) to the notion that "mother nature" is "selecting" some individuals to survive and pass on their genes to the next generation. Over time, some genes will become more abundant in the population's gene pool, some less. Organic evolution can be defined as a change in gene frequency.
How do you record a slump test result?
The slump test gives fairly good consistent results for a plastic-mix. This test is not sensitive for a stiff-mix. In case of dry-mix, no variation can be detected between mixesof different workability. In the case of rich mixes, the value is often satisfactory, their slump being sensitive to variations in workability.
In Antarctica what is the active volcano' s name?
There are about 70 volcanoes on the Antarctic continent. Mt Erebus is fairly consistent in its activity.
What kind of species can evolve from natural selection?
All kinds of species. After all, all species that doexist are the result, primarely, of natural selection.+++That includes us! We were originally an African primate but slowly diffused to many other parts of the world where we needed different approaches to exposure to solar radiation: hence our several different strains (races). One effect only fairly recently know is that different races have different susceptibilities to certain illnesses - again a matter of natural selection although one hard to understand.
How can one person interpretation of their feelings be compared to another?
How we do it varies from person to person but each person's style of interpretation will be fairly consistent
Are vampire bats an endangered species?
No, they are still fairly common in the American tropics.
