Answer:
Temperature, moisture, topography, elevation, soils, hydrology and disturbance.
Explanation:
Temperature, moisture, topography, elevation, soils, hydrology and disturbance are the factors that impact North Carolina ecosystems. Pollution, urbanization and invasive species inversely affected the ecosystem of North Carolina. Industries produces harmful gases that causes pollution as well as make the rainfall acidic which adversely affected the infrastructure as well as plants and animals. The introduction of invasive species also has a negative impact on the plants and animals of that ecosystem.
<u>Answer:</u>
Geologists have sorted earth’s history into different geologic time scale. They just clubbed it into time scales by observing the major changes in the life forms that existed on the earth. Inferring to the fossils found in rocks the time scale was calculated.
First era single cell animals were formed then formed the complex animals.Then Mesozoic era where it is known as the era of dinosaurs. Then the evolution of different species of life during Cenozoic era. These major changes found through fossils helped them to form the GTS.
Answer:
Option 1: Eukaryotic DNA can be highly packaged in condensed chromatin and inaccessible to transcription factors and RNA polymerase.
Explanation:
A process in which chromatin is rearranged in such a way that it comes in a state ready to began the transcription is known as Chromatin remodeling.
Basically, what happens during chromatin remodeling is chromatin changes from a condensed state into a suitable state to begin transcription, in which DNA binding proteins and transcription factors have access to bind to the DNA and start the process of transcription or gene expression smoothly.
Significance of chromatin remodeling:
- The process of chromatin remodeling holds immense importance in the expression of genes because if this remodeling will not occur, the most important gene expression controlling factors would not be able to access DNA and start transcription. Therefore, chromatin remodeling must has to be the first step in gene activation.
- When chromatin is tightly packed,it is referred to as heterochromatin. But when chromatin becomes loose and accessible for transcription it is referred to as euchromatin (please see attached figure for a better understanding).
- Once heterochromatin is changed into euchromatin, the process of transcription begins and makes it possible for the expression of genes in a timely and coordinated fashion.

Brain imaging studies of the Big Five personality traits have found that EXTRAVERSION is associated ............................ Personality psychologists put forward the theory that every human being falls into one of the five basic categories of personality trait. These five traits are called the big five and they are: extraversion, agreeableness, openness, conscientiousness and neuroticism.
The ability of a nerve and muscle cell to receive and respond to a stimulus by changing its membrane potential is called Excitability.
<h3>Nerve cell</h3>
- A nerve cell is an electrically excitable cell that communicates with other cells through specialized connections called synapses.
A group of connected neurons is called a neural circuit.
<h3>Muscle cell</h3>
- A muscle cell refers to either a cardiac muscle cell, or a smooth muscle cell as these are both small cells.
