Answer:
Since the origin of humans on this planet, they have been trying their best to make their lives easier on this planet. In doing so, human activities have some how heavily damaged the Earth. Many day to day activities of humans are dangerous for the Earth.
Some of the consequences of human activities on the Earth's fresh water are :
Extinction of many aquatic species:
The water consumed by humans comes from the fresh water oceans. As the population of humans is increasing enormously, the water from the oceans is being consumed at dangerous levels. This has caused many species of aquatic animals to become extinct or to be at a verge of extinction as they do not have a habitat to survive or reproduce.
Pollution:
Many heavy industries, house sewage, farmers dispose waste into the fresh water. Hence, killing aquatic animals and polluting the fresh water ecosystems.
There are three types of hormonal release control (increase or decrease production), which is stimulated by
1. specific molecules, minerals or particular nutrients ( chemical regulation)
2. other hormones (hormonal regulation)
3. input from nervous system. (neural regulation)
If the inhibition is caused by a different hormone, it would be considered hormonal regulation. In the given example, the hormone is produced in the target organ.
However, if the inhibition is due to the accumulation of the hormone itself, then it is an example of a <em>negative feedback</em>.
Answer:
Three of the four nitrogenous bases that make up RNA — adenine (A), cytosine (C), and guanine (G) — are also found in DNA. In RNA, however, a base called uracil (U) replaces thymine (T) as the complementary nucleotide to adenine
Explanation:
As a result of a domain analysis, ethnographers often identify certain parts or elements of cultural meanings and organize them into larger units. What are these larger units called "cultural domains".
<u>Explanation:</u>
A cultural domain is a set of things that go together in some way, or are the same sort of thing like attires, languages, food, locations, etc. Research of the cultural domain is used to collect information about local culture, the categories people use, the relationships between the categories and the objects used in it. Domains are also named for the divisions. The elements or things of which the domains are composed are governed by culturally specific laws.
