Answer:

It is better to compare the average height gain of control and experimental groups of plants to eliminate all other variables.

Explanation:

If you evaluate individual plants, the data may vary. The experimental group is the one where an experimental procedure is performed while the control group does not receive any treatment.

in 6-8 sentences, explain how stream volume and speed affect the size, shape and flow of streams and rivers.
sukhopar [10]

Explanation:

The higher the volume of water in a stream, the higher its speed and the wide its size and shape which ensures a proportionate flow rate.

To quantify how the speed of stream, we use the quantity, discharge in hydrology;

 Discharge is the volumetric rate of water flow past a point at a particular time.

  Discharge = \frac{volume of water}{time}

  • We see that discharge is directly proportional to the volume of water in a stream.
  • It is inversely proportional to the time taken.
  • We know that volume is the amount of space occupied by a body. It is function of its size and shape.
  • A big water body that is deeper, wider and longer will have more wate and a greater discharge.

ladessa [460]

The answer is single nucleotide polymorphisms (SNPs)

It checks for variation in nucleotide sequences in particular genes that may be different among people, especially in different races. An example is a gene for melanin that would determine the trait for skin color. Single nucleotide changes in the gene between population can be used to differentiate populations.
