Answer:
A) It is composed of a network of moist passageways that permit air to flow from the external environment to the lungs.
Explanation:
The correct statement that describes the RESPIRATORY SYSTEM of human being is option A which states that, It is composed of a network of moist passageways that permit air to flow from the external environment to the lungs.
The sequence of processes leading to the release of energy in living cells is called respiration. The most complex respiratory system is found in mammals ( human beings). This involves the following:
the intake and absorption of oxygen from the surrounding environment; the transport of oxygen to the individual cells in the body; andusing oxygen to release energy (as Adenosine triphosphate) from energy-rich substances.Because human beings are exposed to the atmosphere and have dry body coverings. Gaseous exchange cannot occur through their body surfaces, instead they possess respiratory structures to being dry air in contact with moist surfaces within their bodies. These structures includes:
the trachea andthe lungs ( where bronchi and alveoli are located)TRACHEA or the wind pipe channels the air to the lungs. At the thorax, the trachea into two forming the right and left BRONCHI.
The alveoli is where the gaseous exchange takes place. Tiny blood vessels, called capillaries, are closely wrapped around the outside of the alveoli. This enables oxygen to diffuse across the walls of the alveoli into the blood.
Therefore the correct option that describes the RESPIRATORY SYSTEM of human being is A which states that It is composed of a network of moist passageways that permit air to flow from the external environment to the lungs.
Option B is WRONG because human beings are not unicellular organisms like Amoeba where their gaseous exchange organs are cell membrane or body surfaces.
Option C and D are equally wrong because human beings are not simple animals like amphibians that involves in cutaneous (skin) respiration.

The following diagram shows the branching tree diagram for some animals.
Which two organisms share the greatest number of derived characteristics?
Answer:
If you were asked to create an organizational scheme of your family members, how would you go about doing it? When you stop and think about it, there are several ways to accomplish this. You could outline how relatives are related to each other, or maybe you would sort them based on where they lived. You might even organize them based on characteristics that they have in common, such as hair colour, eye colour, and height.
I hope you found it so helpful
Look at the following diagram of the carbon cycle. An image of carbon cycle is shown. The sun, a cloud, two trees, one on the left and the other on the right, an animal, lake, and a factory are shown in the image. An arrow is shown from the sun towards the left tree marked A. The sun is marked B. There is an arrow from the air above the clouds, marked C, towards the left tree. An arrow from a location close to the ground marked D points towards Dead Organisms, which is a label under the animal. An arrow marked E points from the right tree straight up to the clouds. An arrow marked F points from the animal straight up to the clouds. An arrow marked G points from the factory towards the air above the clouds, C. There is an arrow pointing from the air to the lake labeled Carbonates in Water, an arrow pointing down from dead organisms to Fossils and Fossil Fuels, and an arrow from Fossils to the factory. Which of the following facts is best represented by the arrow pointing from C to A? The energy stored in atmospheric carbon dioxide is conserved because it is used to create new forms of energy present in decomposed plants. The energy stored in atmospheric carbon dioxide is conserved because it is transformed into glucose during photosynthesis. The chemical energy present in carbon dioxide is reduced when it is converted into chemical energy in glucose. The chemical energy present in carbon dioxide is used up completely during the burning of trees.

how does the density of water affect the movement of water around the globe?
Answer:
The Role of Density
Explanation:
Denser water tends to sink, while less dense water tends to rise. Cold-water currents occur as the cold water at the poles sinks and slowly moves toward the equator. Warm-water currents travel out from the equator along the surface, flowing toward the poles to replace the sinking cold water.

What role do genes have in making proteins?
Answer:
A few genes produce other molecules that help the cell assemble proteins.
Explanation:
During the process of transcription, the information stored in a gene's DNA is transferred to a similar molecule called RNA (ribonucleic acid) in the cell nucleus. Both RNA and DNA are made up of a chain of nucleotide bases, but they have slightly different chemical properties. The type of RNA that contains the information for making a protein is called messenger RNA (mRNA) because it carries the information, or message, from the DNA out of the nucleus into the cytoplasm.

16. Eric pours some iced tea into a glass. When he puts the iced tea in the glass, the energy of the glass decreases. What must be true of the energy of the iced tea?
a Its energy stays the same while the energy of the glass decreases. b Its energy decreases while the energy of the glass decreases.
c Its energy increases while the energy of the glass decreases.
d It is impossible to know without data on the number of molecules in each object.
Answer:
the answer is c
Explanation:
the answer c because the ice is getting warmer so the glass is also getting warmer. meaning that the glass is decreaseing in energy while the ice tea is increasing in energy.

Write a non-fiction newspaper article to protect the green sea turtle.
Answer:
Saving the Green Sea Turtle Cheyanne Faith YbarraThe green sea turtle, also known as the green turtle, black turtle, or Pacific green turtle, is a species of large sea turtle found in warm subtropical and tropical ocean waters. The green sea turtle is an endangered species and its population number decreases every year. Recent estimates show us that there are 1.5 million green sea turtles worldwide, and only 300,000 remaining in the Caribbean. Researchers estimate that 4,600 green sea turtles perish each year because of fishing gear, poachers, vessel strikes, loss of foraging habitat, entanglement in or ingestion of marine debris, and the harvesting of their eggs. We can stop the green sea turtles from going extinct by making fishing gear safe for the turtles, staying away from their nesting areas, protect them from poachers, stop the harvesting of their eggs, and keeping the oceans and beaches clean so there is nothing to strangle or poison them. These are just a few ways people can help save the green sea turtles from going extinct.

List the differences between the hearts of vertebrates that live in water and the hearts of vertebrates that live on land. List the similarities.
Answer: All vertebrates have circulatory systems based on a common plan, and so vertebrate systems show much less variety than do those of invertebrates. Although it is impossible to trace the evolution of the circulatory system by using fossils (because blood vessels do not fossilize as do bones and teeth), it is possible to theorize on its evolution by studying different groups of vertebrates and their developing embryos. Many of the variations from the common plan are related to the different requirements of living in water and on land.
Explanation:
Three Anacharis plants were placed inside inverted test tubes filled with water. One test tube was exposed to low light, another to medium light while another was exposed to high light. The table provided shows the results of this experiment. Notice that more oxygen was produced by the Anacharis in high light.
Based on the information provided, what is the difference in volume (in mL) of oxygen produced between the low light and high light plants after 45 minutes? Record your answer below
Answer value
Answer:
Anacharis in High Light produces more mLof oxygen per min than Anacharis in Low Light Anacharis and in Medium Light.
Explanation:
The increased light intensity also increases the rate of photosynthetic activity. As photosynthesis occurs, the energy from sunlight, along with CO2 is converted to chemical energy in the form of glucose.
6CO2 + 6H20 + (energy) → C6H12O6 + 6O2
or Carbon dioxide + water = energy (glucose) + oxygen
Photosynthesizing cells in green plants produce oxygen as a waste product. As this process is rate-limited, certain factors may increase the reaction rate. These include:
carbon dioxide concentration
water availability
ambient temperature
light intensity;
