What are the two factors that define our traits?
coldgirl [10]

There are a few theories as to what defines our traits to create our personality

According to one such theory, Dan P. McAdams claims our personalities develop in <span>three </span>stages:

<span>Our genes cause genetic mutations forming a 'draft' personality.During our early upbringing, our parents, teachers and friends treat us differently based on our looks and draft personality.Once we are older we then form a narrative of our lives based on our experiences growing up, and make decisions consistent with the character we have created.</span>

So our traits started from slight genetic variances, which effected how we were treated, which then shapes our own self-narrative. So really, our personality is one big story that we tell ourselves, and our childhood was the prologue to that story.

The huckleberry patches will provide a very high level of consumption efficiency.

<h3>What is consumption efficiency?</h3>

Consumption efficiency refers to the ability of a consumer to be able to derive the maximum level of consumption from a given resource or group of resources.

The huckleberries depend on the animals such as Bears as well as other herbivores for seed dispersal and propagation. These plants have therefore, develop efficient means to encourage dispersal by these animals. The seeds of the Huckleberries are enveloped in sweet, nutritious fruit that is comparatively undefended.

Harman [31]

Answer:

Because water exhibits cohesive behavior.

Explanation:

Cohesive behavior can be explained as a behavior where molecules are attracted to each other.

And this means that,  water molecules are attracted to each  other because of their cohesive behavior. This makes them to be  attracted to other substances, such as the walls of the xylem of plants.

In this case, it is believed that the water molecules behave this  way because they are polar, that is, there is an electronegativity difference between the bonded atoms. And this enables it to move from the roots to the leaves of the plants.
