Answer:
Sigma factors bind to the promoter region of a particular gene and facilitating the binding of RNA Polymerase to the promoter region (formation of the RNA polymerase holoenzyme complex) in order initiate transcription of the gene.
Put simply - Helps RNA Polymerase do it's job.
Answer:
Underground stem, Aerial stem, and subaerial stem.
Explanation:
Plant stems can be Underground stem, Aerial stem, and subaerial stem due to its presence and strength of the stem. Underground stem are thick stems that run below the ground surface. e.g rhizome. Aerial stems are thin stems that can not stand erect. Examples include watermelon and strawberry etc. Subaerial stems are very thin stems that do not rise up but grow just above the ground. for example, water plantain, flowering rush etc.
Answer: The number of chromosomes in the wolf's body cells is 78 while the gametes has 39
Explanation:
Since each body cell under only mitosis to yield two daughter cells with equal number of chromosome as the parent cell (i.e diploid number, 2n) while sex cells undergo meiosis to yield four daughter cells with half the number of chromosomes as the parent cell (i.e haploid number, n); thus, the wolf's body cells has 78 chromosomes while the gametes has 39 chromosomes.
That would be called pseudocyesis.
Pseudocyesis is when a woman thinks she is going into labor, also called a false pregnancy. <span />
