Answer: Option D) Norepinephrine
Explanation:
Norepinephrine, also known as noradrenaline acts as both a hormone and neurotransmitter.
Its effects is similar to epinephrine, in that during stress conditions epinephrine stimulates the heart to beat and pump blood faster, while norepinephrine helps to maintain blood pressure, causing the narrowing of the blood vessels, known as vasoconstriction.
Answer:
Explanation:
There are four ocean zones named as the neritic zone, midnight zone, twilight zone and abyssal zone depending upon the depth of water and the availability of sunlight. Other factors like pressure, oxygen, salinity contributes to the diversity of organisms found and develop in these zones. These factors also makes the organism unique in forms due to living in the oceanic zone.
The two adaptations are as follows:
1. Many organisms which live in the neritic zone are adapted to bouyancy. Some organisms float to conserve the energy for swimming, others float to fatch food near the surface of shallow waters.
2. The animals in the twilight or disphotic zone are adapted to live life in darkness which is found in cold water and high pressure. They have adaptations such ability to see in dark waters and they produce bioluminescence to catch food in darkness.

Answer:
It will enable gut enzymes to act on the bolus during digestion.
Explanation:
The acidic presence of HCl (hydrochloric acid) in the gastric juice serves as a stimulus for the intestinal wall to produce secretin.
This hormone will act on the pancreas by stimulating the production of pancreatic juice that will contain <u>enzymes</u> (trypsinogen, amylase, lipases) and <u>HCO3⁻</u> (bicarbonate) salts, which have base composition.
With this composition that will be sent to the duodenum, there will be neutralization of acidic solution coming from the stomach and pH leveling around 8.0 (slightly basic) which is great for the enzymes that work there.
