Karyotype is a test to identify and evaluate the size, shape, and number of chromosomes in a sample of body cells. A karyotype test is often used to help find genetic defects in a developing baby.

A explanation because i just took the test
I believe the answer is: Darlene
Formal operational thinking is distinguished by the ability to think about an abstract concept and implement it in order to solve a certain problem. This could be shown in Darlene's method of teaching which seems to be based on a concept that students are much more likely to understand the subject if the teacher directly involved in the process.
The theory of comparative advantage is credited to David Ricardo.
<h3>What is Ricardo's theory of comparative advantage?</h3>
In economics, a comparative advantage occurs when a country can produce a good or service at a lower opportunity cost than another country.
The theory of comparative advantage is attributed to political economist David Ricardo, who wrote the book Principles of Political Economy and Taxation (1817).
Comparative advantage is a key principle in international trade and forms the basis of why free trade is beneficial to countries.
Eg; Consider two countries (China and the UAE) that use labor as an input to produce two goods: wine and cloth.
In China, one hour of a worker’s labor can produce either 5 cloths or 10 wines.
In the UAE, one hour of a worker’s labor can produce either 20 cloths or 15 wines.
The UAE enjoys an absolute advantage in the production of cloth and wine.

Answer:
In the deep ocean layers where the sunlight does not reach, these organisms that are chemoautotrophic use sulfides from the hydrothermal vents to perform chemosynthesis instead of photosynthesis.
Explanation:
Chemoautotrophic organisms are the ones that are adapted to the absence of sunlight. Such organisms identify electron donors in their vicinity and derive energy from the oxidation reactions that these electron donors (mostly, inorganic compounds) undergo.
The major reason for the development of such a trait in these organisms is the depth that they live at. On deep-sea floors, there is an abundance of sulfides. Thus, the organisms living on there make use of the sulfides to fix carbon and obtain energy the required energy to sustain.
The process of chemosynthesis occurring on deep-sea floors due to the presence of carbon, sulfides, and oxygen culminates in the production of organic materials as an end result which the organisms feed on and sustain even when there is no sunlight available. These organisms majorly belong to the bacteria species called Archaea and Extremophiles.
