Rudik [331]

Answer:

Feedback models are tools that provides specific, concise, and clear feedback for a particular thing.

Explanation:

Feedback models are tools that provides specific, concise, and clear feedback for the organization so that an organization can make useful changes which is necessary for the organization growth and development. There is high need of this feedback model which helps us to know about the specific areas where one needs to improve performances in order to work more effectively.

RNA primers in Okazaki fragments are usually very short, less than 10 nucleotides and sometimes as short at 2 nucleotides in len
bagirrra123 [75]

Answer:

During DNA replication each parental DNA strand serves as a template to a new complementary strand. DNA polymerase is the main enzyme responsible for this process, it catalyzes the addition of nucleotides to form the new DNA chain.  

The complementary nature of the DNA strands, presents a difficulty for DNA replication: DNA polymerase catalyzes the polymerization of DNA only in the 5’ to3’ -in the leading DNA strand. Thus, the opposite DNA strand, the lagging strand, faced an obstacle that is solved by the Okazaki small fragments. The primase enzyme synthesizes small RNA fragments complementary to the lagging DNA strand. These RNA fragments serve as primers for the DNA polymerase. To remove this RNA primers and form a continuous complementary lagging strand, RNase H and DNAse ligase will further cut and join the DNA again.  

DNA polymerase has a higher processivity than primase, if processivity is the average number of nucleotides that it is capable to continuously add to the template strand. Primase dissociates from the template often during DNA replication as it has to constantly add new RNA primers to the strand.

A ball was kicked by a player, the ball was stationary, then it gains a velocity of 5 m/s North. Did the ball accelerate or no?
dimaraw [331]

Answer:

Yes, it accelerates

Explanation:

We have that:

The ball was stationary implies that its initial velocity, u = 0

It gained 5m/s means that its final velocity, v = 5m/s

Using first law of newton, we can determine whether it accelerates or not.

v = u + at

Substitute values for v and u

5 = 0 + at

5 = at

Make a the subject

a= \frac{5}{t}

<em>This implies that the ball accelerates over a period of time t</em>

<em></em>

Another way to tell if it accelerates or not is to consider the change in velocity.

When there is an increment in velocity of an object, the object accelerates.

In this case, the velocity increases from 0 to 5. Hence, we can conclude that it accelerates
