Lets say the plant that formed nodules is Species A, and the one who didn't is Species B.
If the nitrogen is concentrated in one area but at a low concentration, then Species A may have formed nodules because it is closer to the concentrated nitrogen. Species B didn't because the nitrogen that is active is being taken by Species A.
<span>The second Mendel's law is the law of independent assortment. According to the law, the alleles for different traits are passed independently to the offspring. This event takes place during meiosis I. In metaphase of meiosis I the chromosomes can line up in different ways and independently. Mother's chromosomes can be on one side and father's chromosomes on the other side or they can be mixed in a different number of ways.</span>
Answer:
<em>Rattus rattus</em>
Explanation:

Black rats are generally omnivorous. They are harmful to farmers because they eat various types of crops. So, for removing Black rat from the crop fields, farmers follow different types of protective ways.
Answer:
(B) open stomata only at night, limiting water loss because of heat and low humidity.
Explanation:
CAM plants are found in the regions characterized by very hot and dry environmental conditions. These plants reduce the water loss through transpiration by exhibiting CAM photosynthesis.
They open the stomata during night time when the air is cooler and rich in moisture. They take in CO2 during night time and fix it into the oxaloacetate which in turn is converted into malate and is stored in the vacuoles.
During day time, stomata remain closed to prevent water loss and the CO2 trapped during night time (released by decarboxylation of malate) enter the Calvin cycle.
The resistance increases then quickly stabilizes!
