Whic A scientist conducted an experiment and discovered that
certain plants grow faster when given a particular amount of
fertilizer. Another scientist conducted the same experiment
and got similar results

This is called replication.Generally, in an experimental set up experimental findings needed to be repeated continuously until a reasonable similar conclusion is reached.

Scientists needed to carry out similar experimental findings to get a similar results, to arrive at a reasonable conclusion.

It is  the stage that is  important for them to check the results arrived at.Replication therefore helps to identify any variability in the experimental results,for accurate results.

Explanation:

answer : haversian

[explanation: -(compact bone is organized as parallel columns, known as haversian systems, which run lengthwise down the axis of long bones. these columns are composed of lamellae, concentric rings of bone, surrounding a central channel, or haversian canal, that contains the nerves, blood vessels, and lymphatic system of the bone)]

many other transport proteins, often called pumps, move materials against a concentration gradient. active transport drives molecules across a membrane from a region of lower concentration to a region of higher concentration. this process, shown in figure 5.1, uses transport proteins powered by chemi- cal energy.
