When constructing the dna molecule what did you notice about the the orientation if the two strnads

One of the strands is inverted. Both the strands are anti-parallel to each other.

Explanation:

Deoxyribonucleic acid (DNA) is a double helix structure made up of two strands. Both the strands remain intact due to the hydrogen bonding present in them.

Both the strands are anti-parallel to each other. One strand runs in the 5'-3' direction and is known as the leading strand. The other strand runs in 3'-5' direction and is known as the lagging strand. Hence, both the strands have an opposite orientation.

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.
