When a plant undergoes cell division in its cambium , that results in the thickening of the stems and the roots, such a plant is said to undergo secondary growth. Therefore if this plant has a layer of cork cambium, definitely the plants has undergo a secondary growth, and it is not a shrub.Because a set of small or medium sized woody plants.
It also shows the the plant is likely to be a dicot, and will eventually produce some seeds. Monocot lacks secondary growth.
Generally most vascular plant contain cambium, and it forms the core parts of their peridermis.
ANSWER: The presence of cork cambium depicts that the plant has undergone secondary growth.
EXPLANATION: Cork cambium is also referred to as is also known as Phellogen (a meristematic cell layer). It is found in vascular plants and located in the peridermis.
However, presence of cork cambium indicates that the plant has undergone secondary growth, which is elicited as a result of cell division in the cambia or lateral meristems, which in turn causes the stem and root to thicken.
Population size of elk increased while the population of aspen tree declined.
Explanation:
As per question, removal of wolves from the system would result in increased elk population due to absence of its predator (wolves). The increased elk population would extensively feed on shrubs and trees like aspen and cottonwood trees. This would cause decline in population size of these shrubs and trees.
A conditioned stimulus is the one which was previously a neutral stimulus but hen it gets paired with the unconditioned stimulus it leads to a conditioned response.
The learned response which is produced in response to a neutral stimulus is the conditioned response.
In the given condition the smell or taste of a chicken salad causes Allison to feel nauseated and hence, the taste or smell of a chicken salad is the conditioned stimulus which generates a conditioned response which in this case is nausea.
