The duodenum is the first section of the small intestine and contains Peyer's patches.

The bile moves upward and backward and pushes the bolus

The bones attaches the liver to the anterior abdominal wall

Tongue toxins prevent water absorption in the large intestine"

Answer:

The duodenum is the first section of the small intestine and contains Peyer's patches.

Explanation:

It is true that the duodenum is the first section of the small intestine where Peyer's patches are located. The duodenum is the place where most of the entire digestive process occurs, in addition, it allows food to mix with bile and digestive juices.

Peyer's patches play an important role in immunological surveillance during digestive processes. This is because it allows the destruction of possible pathogens associated with food, or that interfere with digestion in some way.

Explain why a hydrogen atom can become either an ion or a part of molecule?

NikAS [45]

If it loses that 1 electron (0 electrons, 1 proton, 1 neutron) it become an ion that is positively charge because it has more protons than electrons. [Ignore the neutrons] 

If it gains an electron (2 electrons, 1 proton, 1 neutron) it becomes an ion that is negatively charge because it has more electrons than protons 

A molecule - when 2 or more "different" elements combine or when 2 or more of the "same" elements combine 

1 proton 1 electron <----- that is considered to be neutral 

3 protons, 3 electrons <----- neutral 

5 protons 5 electrons <----- neutral 

6 protons, 5 electrons <-- positive ion [more protons than electrons] 

5 protons, 8 electrons <--- negative ion [more electrons than protons]

Somatic nervous system have - Cranial nerves and Spinal nerves

Autonomic nervous system have - Sympathetic and Parasympathetic system.

The somatic nervous system controls our voluntary and involuntary actions by cranial and spinal nerves and controls all three types of muscles such as cardiac, smooth and skeletal.

The autonomic nervous system controls the involuntary actions of our internal organs.

The sympathetic and parasympathetic system relates to all types of muscle.

The sympathetic and parasympathetic system accelerates and decelerates the heart beat respectively, by this controls the cardiac muscle.

The sympathetic and parasympathetic system stimulates and relaxes our internal organs respectively, by this controls the smooth muscles.

The sympathetic and parasympathetic system prepares our body as a whole for a action and also relaxes our whole body respectively, by this controls the skeletal muscles.

Which of the following is true of vacuoles?

Damm [24]

These are all true- Vacuoles might store food or any variety of nutrients a cell might need to survive but they can even store waste products so the rest of the cell is protected from contamination. They’re also larger in plants than in animals
