Answer:

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

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

3. The main divisions of the peripheral nervous system are the somatic and autonomic systems.

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.

Somatic nervous system 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.
Autonomic nervous system 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.

Some individuals suffer from a rare genetic condition called hemophilia. This condition makes it extremely difficult for the bod

max2010maxim [7]

Solution:

People that born with hemophilia lack or have a low amount of a clotting factor.

Coagulation factors are proteins necessary for normal blood clotting.

Coagulation factors are found in blood plasma. These factors act with Thrombocytes to clot blood.

However, hemophilia is not a decrease in Thrombocytes but a decrease in coagulation factors due to genetic causes.

Diagnosis includes screening tests and clotting factor analysis. Screening tests are blood tests that show whether the blood is clotting properly. Clotting factor tests can reveal a deficiency of clotting factors in the blood plasma and determine the level of severity of hemophilia.

As the coagulation factors are in Blood plasma, we can conclude that the correct answer is:

BLOOD PLASMA

Which factors should scientists measure to learn how each population changed over time?

Art [367]

Explanation:

The statistical study of populations and how they change over time is called demography. Two important measures of a population are population size, the number of individuals, and population density, the number of individuals per unit area or volume.

Nitrogen is a nutrient that organisms need to produce (12) . Plants and animals cannot use the nitrogen that makes up a large pe

Dmitriy789 [7]

Answer:

12. Protein 13. Atmosphere 14. Nitrogen fixation 15. Plants 16. Consumers 17. Urinate 18. Decay 19. Decomposers 20. Ammonia 21. Denitrification

Explanation:

12. Protein

Nitrogen is essential to organisms. It is the main constituent of amino acids, which is the building blocks of protein in organisms.

13. Atmosphere

Nitrogen occurs naturally as gas in the earth’s atmosphere, accounts for about 78% of gases found in the atmosphere. This gaseous Nitrogen which is inert cannot be accessed by plants and animals for use.

14. Nitrogen fixation

For plants to be able to use the gaseous Nitrogen in the atmosphere, Nitrogen fixation has to take place. It involves the turning of gaseous Nitrogen in the atmosphere into ammonia. Nitrogen atoms is combined with Hydrogen atoms by enzyme called “nitrogenase”. This enzyme is present in nitrogen-fixing bacteria.

15. Plants

Nitrogen enters the food web when plants assimilate nitrogen compounds from the soil to form nucleotides, amino acids, and other important chemicals in life.

16. Consumers

Consumers are mainly animals that feed on plants in an ecological food web in other to be able to use the amino and nucleic acids formed from Nitrogen as a major component. Consumers can be categorized as primary, secondary, and tertiary consumers.

17. Urinate

Nitrogen is very much concentrated in the urine of animals and also in their faeces. As animals urinate, Nitrogen is being returned to the soil.

18. Decay

Decay starts, as organisms die. The organisms start decomposing.

19. Decomposers

Decomposers are the bacteria in the soil that break down the nucleic and amino acids in dead organisms into nitrates and ammonia through a process called ammonification

20. Ammonia

This is the end result of the decomposition of dead organisms by decomposers

21. Denitrification

Compounds of nitrogen are turned back into gaseous nitrogen by anaerobic bacteria. This prevents
