Answer:
Plants stem grow against the gravity while roots grow towards the gravity and this prices is known as the geotropism or gravitism explains that the roots grow toward the direction of the gravity pull termed as positive geotropism.
Auxin is a hormone that acts at the bottom of the cell and have different function in roots and stems as in stems it promotes the elongation of the cell against gravity while in roots it is promotes the elongation of the cell towards the gravity.
Answer:
Amoeba reproduces asexually through binary fission. In this process, an individual divides itself into two daughter cells. These are genetically identical to each other.
<span> polymerases, of which there are many. Understanding which types of polymerases perform which functions under which circumstances will clarify the complexity of this topic. The processes of transcription, making RNA from DNA, and replication, copying DNA from DNA, are major functions that require polymerases to link nucleotides into long chains. </span>
For an endergonic reaction, the statement ΔG is positive is
the true statement. So the first option in the given question is the correct
option. Any reaction that requires energy to be absorbed is called an
endergonic reaction. For example, photosynthesis is a great example of
endergonic reaction. In photosynthesis sunlight is required to be absorbed to
complete the reaction. The sunlight acts as the energy required. This type of
reaction is never spontaneous, but requires external force to complete the reaction.
Answer:
2) motion of molecules
Explanation:
heat is a form of energy, molecules with more energy 'vibrate' more
