Homeostasis is defined as a state in which the conditions of an organism's internal environment are maintained within tolerable
Kaylis [27]
There are many cases of homeostasis mechanism. In this mechanism, there will be a receptor that will catch a condition. After that, an order will be sent to various place depend on the condition.
One of them is temperature control which was done by shivering or sweating. When your body temperature is too high, the thermoreceptor will detect it and then the brain will send the order to the body sweat glands. Sweat on body surface will evaporate and reduce body temperature.
When the temperature is too low, the brain will tell the muscle to shiver so you can produce heat.

Other than temperature, homeostasis also control blood pressure, or many chemical level(oxygen, glucose).

Rufina [12.5K]

Answer:

The scientific study of life, called <u>Biology</u><u>, </u>can be organized around several themes. As the biological hierachy builds from molecules on up to ecosystems, each level has <u> emergent properties</u> that result from interactions among component parts. Life's basic unit of <u>structure and function</u> is the cell, which occurs in two basic forms- prokaryotic and eukaryotic . As organisms interact with the environment, <u>nutrients and chemicals</u><u> </u>cycle within an ecosystem, while energy flows one way from sunlight -> chemical energy -> heat. According to the core theme of <u>evolution </u>all of life is related by common descent. Life was diversified as <u>natural selection</u> had led to the gradual accumulation of adaptations that fit populations to the environment.

Explanation:

Emergent properties- Properties that is exhibited by a group of individuals as a result of  interaction among them.

Evolution- the process by which populations develop new characteristic and become more efficient than their ancestors.

Natural selection- A phenomena in which only fittest organisms of a population are allowed to survive in a given environment. This play a key role in evolution.

Carbon-14 is useful for dating fossils that are ______.
MrRissso [65]

Carbon-14 is useful to estimate the date of fossils that are less than 50,000 years old.

Option C

<u>Explanation:</u>

Carbon-14 is the best option to use by estimating the date of fossils that are below 50,000 years old. This is because the carbon-14' half-life is around 5730 years i.e. the existing Carbon-14 in the living bodies decays in 5730 years once they die.

That's the reason Carbon dating utilized to estimate the age of objects that are below 50,000 years old. Objects such as dead plants, wood or human artifacts that are younger than 50,000 years.

After the death of living beings, Carbon 12 and Carbon 14 existing in these organisms starts decaying by converting into Nitrogen. By estimating the leftover amount of carbon 14 in their bodies, scientists can evaluate their age.
