Here is a question about this article: Genetic engineering is the modification of an organism's genome through biotechnology. Since the 1970s, a variety of techniques have been developed to specifically add, remove and edit genes in an organism. Recently developed genome engineering techniques use engineered nuclease enzymes to create targeted DNA repair in a chromosome to either disrupt or edit a gene when the break is repaired. The related term synthetic biology is sometimes used to refer to extensive genetic engineering of an organism.
What is the answer to this question: What is known as the modification of an organism's genome through biotechnology?
****
So... Genetic engineering

Here is a question about this article: One distinctive feature that has caused a great amount of interest among linguists is what is traditionally seen as three degrees of phonemic length: short, long, and "overlong", such that /sd/, /sd/ and /sd/ are distinct. In actuality, the distinction is not purely in the phonemic length, and the underlying phonological mechanism is still disputed.[citation needed]
What is the answer to this question: What is a matter of dispute among linguists regarding the distinction?
****
So... the underlying phonological mechanism

Here is a question about this article: Most copper is mined or extracted as copper sulfides from large open pit mines in porphyry copper deposits that contain 0.4 to 1.0% copper. Examples include Chuquicamata in Chile, Bingham Canyon Mine in Utah, United States and El Chino Mine in New Mexico, United States. According to the British Geological Survey, in 2005, Chile was the top mine producer of copper with at least one-third world share followed by the United States, Indonesia and Peru. Copper can also be recovered through the in-situ leach process. Several sites in the state of Arizona are considered prime candidates for this method. The amount of copper in use is increasing and the quantity available is barely sufficient to allow all countries to reach developed world levels of usage.
What is the answer to this question: What percentage of copper do the deposits have that are extracted?
****
So...
0.4 to 1.0% copper
