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.

List the differences between the hearts of vertebrates that live in water and the hearts of vertebrates that live on land. List the similarities.
Answers
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.

Use the scenario below to answer the following question
Jerimiah and Nicko were discussing how well a vehicle uses its energy. They add a gallon of gasoline to the vehicle and observe the vehicle as their friend drives it in a circle around them. Jerimiah and Nicko hear the sound of the running engine, feel heat coming off of the exhaust and off the engine, and can see the vehicle move around them. After doing calculations they realize the vehicle did not travel nearly as far as they thought it would when it used the gallon of gasoline. Jerimiah claims that the energy must have been destroyed during its use, which is why they both heard the engine noises and felt the heat coming off. Nicko claims that the energy could not have been destroyed, but cannot determine what happened to all of the energy.
What can Nicko say that will explain why the energy was not destroyed during their test?
Answers
Answer:
Nicko: So guys, i'm doing some crazy things with my test today, so the energy wasn't destroyed
Teacher: Why?
Friends: Yeah why loser
Nicko: Because we add a galon of gasoline to the vehicle and observe the vehicle as our friend drive it in a circle around us
Friends: Shut up lose-
Teacher: Guys shut up, Nicko.. can you explain more detail?
Nicko: After doing calculations we realize the vehicle did not travel nearly as far as our thought it would when it used the gallon of gasoline.
Teacher: What's your opinion about that Nicko?
Nicko: I claims that the energy could not have been destroyed, but cannot determine what happened to all of the energy.

In a situation where two parents engage in sexual reproduction their child with have unique adapted traits from the two hosts while asexual reproduction creates a new organism identical to the host, making it useless in a changing environment.

Which statement best describes the human respiratory system? A) It is composed of a network of moist passageways that permit air to flow from the external environment to the lungs. B) Each cell of the human body is in direct contact with the external environment, and gas exchange occurs by diffusion. C) The external body surface is kept moist to allow for gas exchange. D) Gases diffuse across membranes on both the external and internal surfaces of the body.
Answers
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.
