One of the effects of the hormone secretin is to stimulate the release of bicarbonate ions into the duodenum, which neutralizes

avanturin [10]

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 enzymes (trypsinogen, amylase, lipases) and HCO3⁻ (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.

Marco has experienced extreme fatigue (tiredness) lately. He eats three balanced meals each day and exercises 2-3 times per week

Kisachek [45]

Given the symptoms shown by Marcos, we can infer that the organelle that may be causing his problems is the mitochondria.

The mitochondria are one of the most famous and important organelle within a cell. Found in most eukaryotic cells, they are the organelle responsible for most of the energy production of a cell, and throughout the cells of the body, they become responsible for the energy production of the organism. This is the origin of its famous "Powerhouse of the cell" title. Mitochondria produce energy in the form of ATP.

ATP is a molecular compound necessary for most of the reactions that take place in a cell. It is so common as a requirement for any cellular activity that ATP is known as the "molecular currency". Marcos is said to be experiencing chronic fatigue, which is a symptom of mitochondrial disease. When the mitochondria of an organism's cells are not functioning as they should be, the cells do not have the energy needed to perform basic functions.

In reaction to this, the body sends signals to the brain to go to sleep, which minimizes energy consumption by slowing down the metabolic processes which require ATP and thus gives the body time to produce more energy. For these reasons, we can conclude that the fatigue and problems Marcos is experiencing are due to mitochondrial disease.

The San Andreas fault is a transform fault. The map below shows a student's approximation of where the fault line crosses throug

VladimirAG [237]

Answer: Movement along fault line

Explanation:

Here's the remainder of the question:

Which map best predicts the likely movement of land along the fault line over thousands of years?

A transform fault is simply refered to a as a fault that occurs along the plate boundary such that the motion in such case is horizontal and ends when there's a connection with another plate boundary.

Based on the question, the map that best predicts the likely movement of land along the fault line over thousands of years will be a movement along fault line.
