Answer:
A field study is a general method for collecting data about users, user needs, and product requirements that involves observation and interviewing. Data are collected about task flows, inefficiencies, and the organizational and physical environments of users.
According to the way you defined the image, the right answer is C. Amino Acid.
The amino acids found in proteins all have the same basic structure: they are oriented around a central carbon atom, the α-carbon, on which the carboxyl group (-COOH) is articulated, the amino group (-NH2). ), a hydrogen atom (-H) and a lateral group (denoted -R). It is the nature of this lateral group (also called side chain) which differentiates the amino acids between them.
The central α-carbon is therefore asymmetrical in all cases except that of glycine (because glycine has a hydrogen instead of a side chain). This means that it is possible to have two different conformations of the same amino acid conformations that can not be interconverted without breaking and reassembling covalent bonds. These conformations L and D are designated. Although both can be synthesized in the same chemical reaction, only the L-form is used in the proteins.
Explanation:
The eye receives oxygen through the aqueous. Its function is to nourish the cornea, iris, and lens by carrying nutrients, it removes waste products excreted from the lens, and maintain intraocular pressure and thus maintains the shape of the eye. This gives the eye its shape. It must be clear to function properly.
Answer:
Changes in the composition of the atmosphere
Explanation:
Although this answer is very vague and generalized, it is the correct answer.
The increase in greenhouse gas emissions in the atmosphere from modern manufacturing and engineering has increase carbon dioxide and methane concentrations in the upper atmosphere. These gasses have a chemical composition that allows the absorption and release of longwave radiation back to the Earth's surface slowly increasing the global average temperature.
