Laboratory helps you identify things rather than the others using controlled variables
<span>Scientist think convection currents are what cause earths plates to move. a convetion current is caused by the diffrence in the temperature, Mantle material close to the earths core is very hot. Mantle material near the lithosphere is cooler.</span>
The best way to prevent the growth of bacteria on food preparation surfaces is sterilization. Details about sterilization can be found below.
<h3>What is sterilization?</h3>
Sterilization is the process of treating something to kill or inactivate microorganisms.
Sterilization can also be done to prevent the reproduction of microbial population.
It is a known fact that microbes are responsible for food spoilage, hence, to prevent this, it is important to kill or get rid of them.
Therefore, the best way to prevent the growth of bacteria on food preparation surfaces is sterilization.

Answer:
1. Height
2. Girth
Explanation:
The woody plants grow in two manners: the primary growth and secondary growth.
The primary growth is considered the type of growth which increases the height of the plant which involves the apical meristem present at the tip of the shoot.
When the height increases up to its maximum length, then secondary growth begins which add tissues to the side that is it increases the girth by adding bark, secondary xylem and phloem.
Thus, Height and Girth is correct.
Correct answer: Option D- DNA ligase
Explanation: In option A, thymine is a nucleotide, so it is present throughout the replication process, wherever it is required. It is added to the newly formed DNA. In option B, Helicase enzyme is active during initiation and elongation stage, as it facilitates the opening of the winded DNA strands. Option C is nucleotidase and it has no role in DNA replication. So, the correct answer is DNA ligase, which is option D.
The okazaki fragments formed during DNA replication are sealed at the end. And in this step, DNA ligase is used. It catalyzes the formation of phosphodiester bond between the nucleotides of okazaki fragments. So it is the last active molecule of the process.
