2 Choose from the following words to fill in the blanks of the steps in DNA replication. Each one may be used only once. identical new sugar unzip exposed bases original free DNA nucleotides phosphate hydrogen The bonds between the bases break, and the two DNA strands unwind and . are brought in, and they attach to the on both DNA strands. Bonds form between the and molecules of the just-arrived DNA nucleotides, forming a new strand. DNA replication results in two DNA double helices, each composed of one and one strand. The new DNA molecules are to each other and to the original DNA.

7) New

8) Complementary

Explanation:

2 Choose from the following words to fill in the blanks of the steps in DNA replication. Each one may be used only once. identical new sugar unzip exposed bases original free DNA nucleotides phosphate hydrogen  The hydrogen_ bonds between the bases break, and the two DNA strands unwind and nucleotides phosphates are brought in, and they attach to the sugar___ on both DNA strands. Bonds form between the ___original free DNA___ and unzip exposed bases__ molecules of the just-arrived DNA nucleotides, forming a new strand. DNA replication results in two DNA double helices, each composed of one ___identical___ and one ___new__ strand. The new DNA molecules are complementary to each other and  the original DNA.

not only is it colder, it also becomes darker, less salty, and more dense.

measuring light intensity

light meters can be used to measure light intensity. the meter is held at the soil surface and pointed in the direction of the maximum light intensity, and then the meter is read.

errors can be made when measuring light intensity by accidentally shading the light meter. the reliability of the results can be checked by taking many samples.
