The correct answer is option B, The spread of the roots around the plants is usually greater than the depth
The growth of the roots in the plant is not directed towards any nutrients or resource. Alternatively the growth of roots is diverted towards the availability of oxygen. Since the availability of oxygen decreases exponentially with the depth below the surface of soil, the root growth is dampened after a certain depth in the soil. Also factors like clay content, resistance to penetration also restricts the root growth downward. These restricting factors are not available in the horizontal direction of growth of roots. Thus roots grow more laterally than vertically.
Water is a polar molecule because its opposite ends have opposite electric charges.
Answer:
A transcription factor
Explanation:
In order for transcription to begin in eukaryotes, not only must RNA polymerase be attached to the double strand of DNA, but several transcription factors must also be binded. Without them the RNA polymerase machinery will not start.
In example GTF's (General transcription factors), also known as basal transcriptional factors, are protein factors that binds into the promoter on DNA to activate transcription. The basic transcriptional apparatus that first bind to the promoter is RNA polymerase + GTFs +a multi-protein complex.
Eukaryote because its apparently living organism
