Correct answer is option D.
Transcription activators accelerate transcription, while transcription factors assist RNA polymerase binding.
<h2><u>
</u></h2><h2><u>
Explanation</u></h2>
Transcription factors are the proteins which help in proper binding of RNA polymerases in the promoter region of DNA so as to facilitate transcription.
Activators on the other hand, help in the enhancement of the transcription rate.
Transcriptional activators are basically proteins which bind to the regulatory elements known as enhancers so as to increase the rate of transcription. Enhancers are specific DNA sequences, which may be present in the upstream or downstream region of the gene which is going to be transcribed.
It may be noted here that transcription factors are only present in eukaryotes. In prokaryotes, sigma factors are present instead of transcription factors to facilitate proper binding of RNA polymerases on the DNA.
The genotypes would be bbTT X BbTt
Assuming that bark color is represented by B (b) allele and height is represented by T (t) allele.
Since the traits show simple dominance: blue (B) of dominant over purple (b) and tall (T) is dominant over short (t)
- The genotype of a tree that is purebred purple (bb) and tall (TT) would be bbTT
- The genotype of a tree that is heterozygous for both trait would be BbTt
- Thus, the cross would be bbTT x BbTt

Heat can be transferred from one object to another since, If there is a temperature difference between two systems, heat will always find a way to transfer from the higher to the lower system.
Kinetic energy can be transferred from one object to another, when two objects crash. One example of kinetic energy being transferred from one object to another would be a collision of pool balls, Since one ball would hit another causing it to move. Also Kinetic Energy is, “The <u>energy</u> of motion, observable as the movement of an object, particle, or set of particles. Any object in motion is using kinetic energy: a person walking, a thrown baseball, a crumb falling from a table, and a charged particle in an electric field are all examples of kinetic energy at work.”
And last but not least, Thermal Energy which, is often referred to as heat. The thermal energy of matter depends on how fast the atoms or molecules are moving. The faster they are moving, the more thermal energy they possess. Therefore, the temperature of the matter would be higher. Thermal energy is a form of kinetic energy. One example of Thermal energy being transferred from one object to another is, Thermal energy from a hot stove is transferred to a metal pot and causes the water molecules to move faster increasing the temperature of the water. Fun fact; Thermal Energy can be transferred in three ways known as, Conduction, Convention, Radiation.
Coevolution happens when the genetic development between two or more species affects the evolution of each other. An example would be hummingbirds and bird-pollinated (ornithophilous) flowers. The ornithophilous flowers give nourishment to the birds with their nectar that has high sugar content. The birds in return aids in the pollination of these flowers.
Answer: The genes passed on by the parents can combine in a new way in the child.
