Velocity is a measure of how fast something moves in a particular direction. In other words, a velocity is a speed with a direction. For instance, if an object moves east at 9 metres per second (9m/s), we would say that its velocity is 9 m/s to the east.
Gradient The formal definition of a concentration gradient is the process of particles, which are sometimes called solutes, moving through a solution or gas from an area with a higher number of particles to an area with a lower number of particles. The areas are typically separated by a membrane.

Answer: 320 phosphate groups.
<u>Each nucleotide of DNA contains one phosphate group attached to it</u>.Therefore if there <u>were 160 nucleotides in a strand;,definitely each nucleotide of the strand must contain one phosphate group, therefore 160 phosphate groups. must be present.</u>
However, a DNA molecule must contain double strands, therefore 160 multiplied by 2 should give 320 phosphate groups in the alien DNA.

Explanation:
Trees and other plants absorb carbon dioxide from the atmosphere as they grow. This is converted into carbon and stored in the plant's branches, leaves, trunks, roots and in the soil. Cutting down of trees without allowing them to regrow, the carbon stored is released to the atmosphere in form of carbon dioxide which contributes to as much as 30 percent of global greenhouse-gas emissions.
