Answer:

Theories develop through repeated experimentation.

Explanation:

<em>The correct answer would be that t</em><u><em>heories develop through repeated experimentation.</em></u>

A theory is internally consistent and is only arrived at after several independent experimentation based on the same phenomenon. That is, when a scientist reports a findings, the reports must have been widely tested by different researchers using the same experiment and arrive at similar findings before they can become a theory.

Hence, the information on the theory explaining the movement of sand beaches is valid because the experiment must have been repeated by several independent researchers and similar results must have been obtained before the theory is arrived at.

Water is able to travel against gravity, from the roots of a plant to the leaves at the top of the plant.
Juliette [100K]

Answer:

<em>The correct option is B) Capillary action, when adhesive forces are stronger than cohesive forces.</em>

Explanation:

When water leaves from the leaves of a plant through events such as transcription, a gap is produced in the capillary action of the xylem tube. As a result, more water is drawn from the roots to fill the void. The forces of attraction between the water and the xylem tube are much greater than the intramolecular forces of water. As a result, the water flows in an upward direction due to these string adhesive forces present between the water and xylem tube.

What happens first when the amount of sunlight decreases?
dezoksy [38]
Light energy absorbed by chlorophyll is converted into chemical energy. Some of this energy is used to split water into hydrogen and oxygen. Some of the chemical energy is used to make ATP from ADP and phosphate (Pi). This chemical energy is stored as ATP.

A template strand of DNA is read in the _____ direction in order to direct synthesis of RNA in the _____ direction.
Gelneren [198K]
The RNA synthesis or ADN transcription occurs in the nucleus and requires:
  - DNA strand to act as a template.
  - Enzymes, specially the RNA-polymerase.
  - Ribonucleotides of Adenine, Guanine, Cytosine and Uracil.
This consist of three maturation of the 3'-->5' direction while the sense of RNA synthesis is 5'-->3'.
This is fulfilled because the enzyme selects the ribonucleotide whose base is complementary to the DNA chain that acts as a template, and binds it by means of a nucleotide bond, releasing a phosphate group.
