<span>#1) With reference to the role of oncogenes, explain how the normal controls over the cell cycle can be lost.
Answer: The way that cell cycle can be lost is by going through changes in the activity of cell cycle regulators. Cancer causes different types of mutations. There are two types of cell cycle regulators that can promote the development of cancer:
-Positive Regulators that can be over activated (become oncogenic).
-Negative Regulators (tumor suppressors) which can be inactivated.

They compete by food source because they both eat bugs and there for compete on who gets the bugs.
Answer:
co-dom: both traits show without either completely masking each other: red flower x white flower = pink offspring.
incomplete: both traits show but dont mask: red x white = red and white flower
simple: one dominant trait masks the recessive trait, red x white (where red is dominant) = primarily red flowers (depending on if the flowers are heterozygous or homozygous there will be a different number of red flowers, with a minimum of 2/4).

The list of <span>not correctly paired parasympathetic outflow </span><span>would be:
1. nerves coming from the sacral section innervate lungs and heart
</span><span>2. vagus nerve stimulates many glands in the head like lacrimal and salivary glands

Sacral region is located in the tailbone, near the hip. The location itself too far from lungs and heart, which actually nerved by vagus.
</span>Lacrimal and salivary glands are nerved by the submandibular (cranial VII) and glossopharyngeal(cranial IX), not vagus(cranial X)
