Human-centered technology often recommends _______ao
lidiya [134]

Answer:

Creating objects which people are going to interact with, designers have to be aware of those traits and take them into account in the process. ... Continuing the theme, user-centered design is more focused and concise version of human-centered design with deeper analysis of target audience.The user interacts directly with hardware for the human input and output such as displays, e.g. through a graphical user interface. The user interacts with the computer over this software interface using the given input and output (I/O) hardware.Human-centered design is a creative approach to problem solving and the backbone of our work at IDEO.org. It's a process that starts with the people you're designing for and ends with new solutions that are tailor made to suit their needs. ... Human-centered design consists of three phases.

What was his beliefs?
Citrus2011 [14]

A belief is an attitude that something is the case, or that some proposition about the world is true.[1] In epistemology, philosophers use the term "belief" to refer to attitudes about the world which can be either true or false.[2] To believe something is to take it to be true; for instance, to believe that snow is white is comparable to accepting the truth of the proposition "snow is white". However, holding a belief does not require active introspection. For example, few carefully consider whether or not the sun will rise tomorrow, simply assuming that it will. Moreover, beliefs need not be occurrent (e.g. a person actively thinking "snow is white"), but can instead be dispositional (e.g. a person who if asked about the color of snow would assert "snow is white").[2]

There are various different ways that contemporary philosophers have tried to describe beliefs, including as representations of ways that the world could be (Jerry Fodor), as dispositions to act as if certain things are true (Roderick Chisholm), as interpretive schemes for making sense of someone's actions (Daniel Dennett and Donald Davidson), or as mental states that fill a particular function (Hilary Putnam).[2] Some have also attempted to offer significant revisions to our notion of belief, including eliminativists about belief who argue that there is no phenomenon in the natural world which corresponds to our folk psychological concept of belief (Paul Churchland) and formal epistemologists who aim to replace our bivalent notion of belief ("either we have a belief or we don't have a belief") with the more permissive, probabilistic notion of credence ("there is an entire spectrum of degrees of belief, not a simple dichotomy between belief and non-belief").[2][3]

Beliefs are the subject of various important philosophical debates. Notable examples include: "What is the rational way to revise one's beliefs when presented with various sorts of evidence?"; "Is the content of our beliefs entirely determined by our mental states, or do the relevant facts have any bearing on our beliefs (e.g. if I believe that I'm holding a glass of water, is the non-mental fact that water is H2O part of the content of that belief)?"; "How fine-grained or coarse-grained are our beliefs?"; and "Must it be possible for a belief to be expressible in language, or are there non-linguistic beliefs?".[2]

A cell has 12 pairs of sister chromatids in G2 of the cell cycle. How many pairs of homologous chromosomes should be seen at met
Basile [38]

Answer:

6 pairs of chromosomes

Explanation:

The cell cycle consist of 4 phases:

G1 Phase

S  Phase

G2 Phase

M Phase

G1 Phase

In the G Phase cell duplicates its organelles. In the example the cell has 6 pairs of chromosomes. In every pair of chromosomes one chromosome comes from the father and one chromosome comes from the mother. Although these chromosomes carry similar genetic information there are some differences between them.

S Phase

In the S Phase each chromosome is duplicated

In the example the cell has 12 pairs of chromosomes. Since each chromosome has a identical copy, they are called sister chromatids.

G2 Phase

In G2 phase cell prepares for mitosis. In the example the cell has 12 pairs of chromosomes.

M Phase

The M phase in the Meiosis is divided in Meiosis 1 and Meiosis 2

In Meiosis 1 pairs of sister chromatids  align  and undergo homologous recombination. For chromosome 1 ,  2 pairs of sister chromatids align and mix their genetic content. In the example the cell has 12 pairs of chromosomes. At the end meiosis 1,  6 pairs of chromosomes goes to one side of the cell and the other 6 pairs of chromosomes go to opposite side of the cell. Finally the cell divides and two cells are formed, each cell has 6 chromosomes.

At the metaphase 2 Meiosis each pairs of homlogous chomosomes is aligned al the center of the cell. In the example you have 6 pairs of chromosomes in each cell aligned at the center.
