Answer:

<em>1. The characteristic thing about </em><em>adult frog breathing</em><em> is that </em><em>drawing in air by lowering their mouth floor</em><em> (option d).</em>

<em>2. The substance released by the </em><em>lung secretory cells </em><em>is the </em><em>surfactant </em><em>(option c).</em>

<em>3. The main divisions of the </em><em>peripheral nervous system</em><em> are the </em><em>somatic and autonomic systems</em><em>.</em>

Explanation:

<h3>1. Breathing of the adult frog</h3>

The adult frog - while out of the water - uses a nasal breath, propelling air into its throat and oral cavity. The air content in the frog's mouth causes the internal pressure of the cavity to increase, and the floor of the mouth is modified to allow the passage of air to the lungs.

Under water, the frog's breath is cutaneous, that is, through its skin.

Adult frogs do not have gills or respiratory muscles.

<h3 /><h3>2. Pulmonary surfactant </h3>

Pulmonary surfactant is a substance produced and secreted by the pulmonary epithelium, specifically by type II pneumonocytes. The function of the surfactant is to keep the pulmonary alveoli open to allow gas exchange.

The surfactant is a substance of a lipidic and proteic nature that helps reduce the surface tension of the water, which in the socket prevents closure when the air is exhaled.

Another function is to prevent the germs - viruses and bacteria - present in the air from passing from the alveolus to the bloodstream.

<h3 /><h3>3. Divisions of the peripheral nervous system</h3>

The peripheral nervous system is dependent on the central nervous system and is made up of all the nerves that go to each of the tissues and organs of the body. It is divided into somatic and autonomic nervous systems.

  1. <u>Somatic nervous system</u> is composed of nerves that drive nerve impulses to skeletal muscles, being predominantly voluntary. The involuntary response in this system is due to the existence of reflex arcs, whose center of integration is the spinal cord.
  2. <u>Autonomic nervous system</u> is responsible for the innervation of coughs the internal organs, allowing their function under the coordination of the central nervous system. It is an involuntary system and is subdivided into sympathetic and parasympathetic systems.

The integration of both systems, somatic and autonomic, allows a body to perform all its functions, including the function of relationship, alertness and maintenance of organic homeostasis.

What ecological lesson can we learn from the controlled experiment on the clearing of forests?
VashaNatasha [74]

Vegetation controls water and nutrient loss from ecological lesson can we learn from the controlled experiment on the clearing of forests.

<h3>What about clearing of forest?</h3>
  • Deforestation is the intentional clearing of wooded land.
  • Forests have been cleared throughout history and into the present era to make room for agriculture and animal grazing as well as to obtain wood for fuel, manufacture, and construction.
  • Deforestation has dramatically altered the landscape all around the planet.
  • The process of permanently removing vegetation, such as trees and bushes, together with their roots, is known as clearing woods and forests.
  • There are both direct and indirect causes of deforestation.
  • Natural factors including storms, fires, parasites, and floods are among the direct culprits.
  • Human activities include the extension of agriculture, the raising of livestock, the extraction of timber, oil, and minerals, the building of dams, and the development of infrastructure.

What is El Niño?
Anastasy [175]

El Niño: an irregularly occurring and complex series of climatic changes affecting the equatorial Pacific region and beyond every few years, characterized by the appearance of unusually warm, nutrient-poor water off northern Peru and Ecuador, typically in late December.

La Niña: a cooling of the water in the equatorial Pacific, which occurs at irregular intervals, and is associated with widespread changes in weather patterns complementary to those of El Niño, but less extensive and damaging in their effects.

how they differ: La Niña is sometimes referred to as the cold phase of ENSO and El Niño as the warm phase of ENSO. These deviations from normal surface temperatures can have large-scale impacts not only on ocean processes, but also on global weather and climate. ... Typically, El Niño occurs more frequently than La Niña.

What is the function of spines on cacti
soldier1979 [14.2K]

The spines of the cactus have several functions, which are the following:

To defend them from possible predators: inside the body of the plants there is a great deal of water; if herbivores could access it, these plants would not survive.

To provide them with shade: it is true that not much, but it is enough so that the loss of water by evaporation is minimal.

Reflect sunlight: many species have white spines.
