In all cells, separation of replicated chromosomes is a prerequisite for cell division. However, the mechanism of chromosome sep

aration in bacteria is distinct from that in eukaryotes in several ways. Sort the following into Bacteria only, Eukaryotes only, Both Bactria and eukaryotes.1. two copies of the duplicated chromosome are attached at their centromeres before separating2. chromosomes replicate before cell division3. chromosome separation begins at the origin of replication on DNA4. Before separation duplicated chromosomes condense; nuclear envelope fragments permitting chromosome separation5. replicated chromosomes separate by attaching to some other structural feature of the cell

1. two copies of the duplicated chromosome are attached at their centromeres before separating

2. chromosomes replicate before cell division

3. chromosome separation begins at the origin of replication on DNA

4. Before separation duplicated chromosomes condense; nuclear envelope fragments permitting chromosome separation

5. replicated chromosomes separate by attaching to some other structural feature of the cell

Explanation:

In the given question, the DNA replication steps of both prokaryotes and eukaryotes are provided in which some are common to both eukaryotes and prokaryotes and some are unique to the prokaryotes and eukaryotes.

<u>Eukaryotes </u>

1. Option-4 as the nuclear envelope is present in eukaryotes only.

2. Option-1 as centromere allows the kinetochores bind to the centromere which separates the chromosome.

<u>Bacteria </u>

1. Option-3 as DNA replication process separates the strand of the DNA.

<u>Both </u>

1. Option-5 as the chromosomes separate by other structures like microtubules

2. Option-2 as genetic material to be passed on to the generation must be replicated.

How does wet and dry barometer work?? Thnx
tatiyna

Wet barometer - The tool works by measuring atmospheric pressure to predict incoming weather. Since the glass is only filled halfway with water, the other half is exposed to the atmosphere. When the outdoor atmospheric pressure rises, the pressure in the glass decreases, and causes the water to move down the spout.

Dry barometer - A Torricellian barometer (sometimes called a mercury barometer) is an inverted (upside-down) glass tube standing in a bath of mercury. Air pressure pushes down on the surface of the mercury, making some rise up the tube. The greater the air pressure, the higher the mercury rises.

I hope this helps!

Classical conditioning is
leonid [27]

Answer:

Classical conditioning (also known as Pavlovian or respondent conditioning) is learning through association and was discovered by Pavlov, a Russian physiologist. In simple terms, two stimuli are linked together to produce a new learned response in a person or animal.

The most famous example of classical conditioning was Pavlov's experiment with dogs, who salivated in response to a bell tone. Pavlov showed that when a bell was sounded each time the dog was fed, the dog learned to associate the sound with the presentation of the food.

John Watson proposed that the process of classical conditioning (based on Pavlov’s observations) was able to explain all aspects of human psychology.

Everything from speech to emotional responses was simply patterns of stimulus and response. Watson denied completely the existence of the mind or consciousness. Watson believed that all individual differences in behavior were due to different experiences of learning. He famously said:

If the characteristic is eye color, what could be two different phenotypes?
Feliz [49]
The phenotype is just a characteristic/trait. 

For instance Brown and Green are phenotypes of eye color. 

This can also be used in Punnet Squares, and could be displayed as B and G. 
B equaling dominant Brown, and G = dominant Green, vice versa to g and b where they are recessive.
