. Igneous rock is formed through the cooling and solidification of magma or lava. The magma can be derived from partial melts of existing rocks in either a planet's mantle or crust. Typically, the melting is caused by one or more of three processes: an increase in temperature, a decrease in pressure, or a change in composition. In this case, the "rock" is ice. The hot water has cooled through a change of temperature to create a solid structure (ice).

(opening the door) describe the work of at least 3 body organ Systems that work during the process.

My name is Ann [436]

Explanation:

When a person opens the door, he or she uses 3 systems:

1. Nervous system: from the nervous system, neural instructions are generated through electrical impulses towards the muscles of the upper limb so that they make the necessary movements to open the door.

2. Muscular system: through the muscles of the trunk and the upper limb, it generates voluntary movement to open the door.

3. Skeletal system: the bones are the support of the soft tissues and the fulcrum of most of the skeletal muscles. In this sense, it serves as a support for the muscles of the trunk and the upper limb to carry out the movement of opening the door.

we can conclude that the correct answer is:

Answer:

1. Nervous system: instructions are generated from the nervous system by means of electrical impulses towards the muscles of the upper limb so that they carry out the necessary movements to open the door.

2. Muscular system: the muscles of the trunk and the upper limb generate voluntary movement to open the door.

3. Skeletal system: it supports the muscles of the trunk and the upper limb to carry out the door opening movement. It also has joints that help the mechanical movements necessary to open the door.

Anuta_ua [19.1K]

Her hypothalamus will secrete vasopressin. If her dehydration becomes severe, her secretion of vasopressin will increase.

<h3>What is vasopressin?</h3>

The posterior pituitary gland releases the peptide hormone vasopressin, also known as antidiuretic hormone.
Which is produced by the supraoptic and paraventricular nuclei of the hypothalamus (neurohypophysis).

It primarily functions as an anti-diuretic in the kidney, where it causes the body to reabsorb water by acting on the distal region of the nephron when it is dehydrated.
The AVP gene for it is found on human chromosome 20.
Vasopressin has an antidiuretic effect; it reduces the volume of urine by raising the collecting tube's water permeability.
It attaches to the G protein-coupled V2 receptor, which in turn starts a signaling cascade through the PKA.
Aquaporin 2 (a transmembrane pore) is produced as a result, and it is then transported to the apical/urinary membrane.
