Because technically there is no such thing as cold
all that exists is heat
this is because heat is the rapid movement of particles, made by friction (to understand why you must delve into physics and some chemistry)
so, when you feel cold, it's really the absence of heat
so instead of "keeping the cold out", which makes no sense at all scientifically, insulation keeps the heat in.

as a side note
the feeling of cold is produced when you come in contact with an object (yes, air counts) that has less heat, or energy, than you do, You feel cold because heat (energy) from your body is being transferred to the environment. This ABSENCE OF HEAT in your body is why you feel cold

If a natural disaster caused all warbles to go extinct, why would the natural disaster not kill all living organisms?
likoan [24]

Answer:

Living organisms that are able to adapt to the environment (natural disaster) will increase in number while the ones such as warbles who can't adapt will die and go into extinction.

Explanation:

Natural selection can be defined as a biological process in which species of living organisms having certain traits that enable them to adapt to environmental factors such as predators, competition for food, climate change, sex mates, etc., tend to survive and reproduce, as well as passing on their genes to subsequent generations.

Simply stated, natural selection entails the survival of the fittest. Therefore, the species that are able to adapt to the environment will increase in number while the ones who can't adapt will die and go into extinction.

Additionally, due to genetic variation within populations, some living organisms have a better chance of possessing good or beneficial traits being passed from the parent organism to her offsprings which enables them to survive a natural disaster.

Hence, if a natural disaster caused all warbles to go extinct, the natural disaster may not kill all living organisms due to natural selection.

A brown cow is mated with white cow and they produce a roan cow Roan cows are brown with white spotsWhich statement best explain
jek_recluse [69]
C.
In co-dominance both traits show up, and in incomplete dominance the two traits mix together.

So automatically A, B and D are wrong, since we can see both brown and white colors on the cow separately.

If it were any of those we wouldn't be able to see any of the traits alone they would be a mix.

Hi everyone!:) i just need help with this science question in my textbook!
Katyanochek1 [597]

Answer: In a simple sense, growth in population is a good thing as it means that a species is thriving and doing well in its environment as well as reproducing at desirable rates.  However, if population continues and continues to grow it will eventually reach a cap where an environment can no longer hold more members of that specific species because there is a limit on food and places of shelter.  This leads to natural rises and declines in a species over time (which can be very predictable as well.)  A downside to rapid and sustained population growth is that if a species keeps growing and growing without reaching its cap (which happens a lot with introduced species into an environment which were not there naturally) is that they can overrun and destroy a natural environment and damage the ecosystem.  Animals and species which are already there can have their population numbers drastically reduced because of this invasive species and may be forced to move to a new area.
