Option D
polymerase chain reaction (PCR) do Makes more copies of a sample of DNA
<u>Explanation:</u>
A procedure to create several portraits of a distinct DNA section is termed as Polymerase chain reaction. In other words, it is a lab routine handled to compose various representations of a portion of DNA. PCR is extremely explicit and can be utilized to increase, or model, a particular DNA destination from a hybrid of DNA particles.
In PCR, the effect is regularly cycled within a range of temperature variations, which deduct countless models of the destination range to be exhibited. PCR intends to obtain sufficient of the objective DNA region that it can be examined or applied in some other way.
The order is calcification of matrix >> cells differentiate into osteoblasts >> formation of the primary ossification >> osteoclasts break down the spongy bone >> formation of the secondary ossification (5,3,1,2,4). It is a fundamental process.
<h3>What are osteoblasts?</h3>
Osteoblasts are cells of the bones, which act to generate bone matrix and modulate the process of mineralization of the skeleton.
Endochondral ossification refers to the mechanism through which the cartilaginous bones generate longitudinal growth.
This mechanism (endochondral ossification) is fundamental during fetal/embryo development.

In science, a theory is a hypothesis, and a law is a statement of a observed phenomenon proven to be true.
- A theory explains why a natural phenomenon occurs.
- Scientific laws summarize a set of observations about a natural phenomenon that was witnessed.
- Both can be revised, used to make predictions, and are based off of a hypothesis.
Explanation:
The conversion of Celsius to Kelvin: Kelvin = Celsius + 273.15. Instead of 273.15 the value of 273 is also used.
