Crossing a BB male with a Bb female:
The Punnett Square will look like this:
BB BB
Bb Bb
The percentage will be as follows:
- You will have 50% homozygous dominant (BB)
- You will have 50% heterozygous (Bb)
Now, for the phenotype, you will have 100% black fur, since B is dominant and is prevalent in 100% of all the breeds.
For the genotype, you have 50% BB and 50% Bb
Answer:
1) Recursive definition: 
2) At the beginning of the 4th interval
Explanation:
1)
The initial population of the bacteria at time zero is

Here we are told that the reading is taken every two hours; we call this time interval "n", so

And also, after every time interval n, the number of bacteria has tripled.
This means that when n = 1,

And when n=2,

Applied recursively, we get

And substituting p0,
(1)
2)
Here we want to find at the beginning of which interval there are

bacteria.
This means that we can rewrite eq.(1) as

By simplifying,

Which means that

However, this means that the number of bacteria is 1,350,000 after 3 time intervals; therefore, at the beginning of the 4th interval.
This is known as Onesky.

<u>Answer</u>:
The distinction between the sensation and perception allows the researchers to distinguish between the information processed by the receptors versus the information processed in the cortex.
<u>Explanation</u>:
The sensation is a process by which the sensory receptors take up the signals or stimuli from its surroundings and send it to the brain through nerves. Whereas, in the process of perception the brain organizes, combines and makes patterns from the given stimuli and gives the response to the particular stimuli accordingly.
Both sensation and perception are connected to each other hence if one doesn’t work then the other automatically stops working.
