Answer:
All organisms grow, develop, and reproduce. Some organisms reproduce on their own, producing an identical offspring through asexual reproduction. In sexual reproduction two parents combine their DNA to produce genetically unique offspring.
Explanation:
In asexual reproduction, what is produced is basically a clone. Since the organism is reproducing using only its own genetic material, no combination happens. The new organism is genetically identical to its parent. Examples of organisms that reproduce this way are bacteria and hydras.
On the other hand, sexual reproduction produces individuals that are genetically different from their parents. Part of their genetic material comes from their father, and the other part from their mother. That is the case with humans, for example. A DNA test can show you are your parents' son or daughter because part of your material comes from each of them.
Answer:
Most economists think that the rise in the demand for cash is caused by the rise of the underground economy and the use of U.S. currency as a store of value.
Explanation:
The US dollar is the currency most used as an international monetary reference in the world, along with other currencies such as the Euro, the Yen, the Yuan and the British Pound, although all of these are used in a smaller proportion than the currency of the United States.
In many countries that do not have a strong local currency, or even in nations with stable but not internationally relevant currencies, citizens save in US dollars, because US dollars guarantee savings stability that other currencies, due to their volatility, cannot guarantee. Therefore, there is a large amount of cash that is outside the United States, in bank deposits or even domestic savings of millions of people around the world, which increases the demand for cash.
