What makes the Oxygen Family unique?
Answer:
Oxygen is in group 16 in the periodic table. All the elements in this group have in common the number of valence electrons in their outer shell (6 valence electrons). The only reason I can see that they may be considered "mixed" is because the group includes non metals and metalloids.
Explanation:
This substance attaches to oxygen and carbon dioxide gas in the blood.
Answer:
If given a choice between blood cells, hemoglobin, plasma, platelets, the correct answer would be hemoglobin. Otherwise, the correct answer is hemoglobin.

Use complete sentences to explain how the mass of hydrogen is conserved during cellular respiration.
pls make it simple and not write a whole paragraph
Answer:
Explanation:
The mass of hydrogen is conserved during cellular respiration as it follows the Law of Conservation of Matter.
Answer:
the law of conservation of matter
Explanation:
The mass of hydrogen is conserved during cellular respiration as it follows the Law of Conservation of Matter.
The Law of Conservation of Matter states that the reactants must equal the products, which is demonstrated through the equation that demonstrates cellular respiration.
C6H12O6 + 6O2 -> 6CO2 + 6H20
This shows that hydrogen has been conserved throughout the entire process (H representing Hydrogen) as the product has the same amount of hydrogen as the reactants.

Answer:
Gold, sodium, aluminum
Explanation:
The metals are located on the left side of the periodic table
Gold,sodium,aluminum are the metals.
The periodic table's left side is where the metals are found.
Silvery-white and light in weight, aluminum is a metal.
Sodium is a soft metal that tarnishes when exposed to air in a matter of seconds
Which elements are metallic?
Iron.Uranium.Sodium.Aluminum.CalciumSilvery-white and light in weight, aluminum is a metal. It is supple and moldable. Cans, foil, culinary utensils, window frames, beer kegs, and airplane parts are just a few examples of the many goods that employ aluminum. This is as a result of its distinctive attributes.
Sodium is a soft metal that tarnishes when exposed to air in a matter of seconds. With water, it also reacts strongly. Sodium is employed as a reagent in the chemical industry and as a heat exchanger in some nuclear reactors. Salts of sodium, however, are more useful than the metal itself.

Dalton believed atoms were made mostly of empty space.
The number of protons in an element is always equal to the number of neutrons.
Plasmas have a net negative charge.
Solids have a fixed mass, volume, and shape.
Katrina is investigating the properties of volume for the different states of matter. First, she places a cube in a bowl of water and observes what happens. Next, she takes the cube out of the water and pours the water into a glass. Which statement describes the observations Katrina made of the cube and the water?
A: When the cube was placed in the water, the shape of the cube stays the same. When the liquid was poured from the bowl into the glass, the shape changed.
B: When the cube was placed in the water, the volume of the cube changed. When the liquid was poured from the bowl, the shape changed.
C: The volume of the cube and the water changed when the cube was placed into the water. The volume of the liquid changed when it was poured out of the bowl.
D: The shape and volume of the cube and the liquid changed when the cube was placed in the bowl. The liquid stayed the same when it was poured from the bowl.
The answer would be
B: When the cube was placed in the water, the volume of the cube changed. When the liquid was poured from the bowl, the shape changed.

List the five physical phase changes of matter and give one example for each.
Answer:Melting.
Freezing.
Evaporation.
Condensation.
Sublimation.
Explanation:
Answer: Examples for the five transformations previously given.
For the first four, we encounter common examples in everyday life, all to do with water:
Freezing - liquid to solid, e.g. water to ice, e.g. making ice cubes.
Melting - solid to liquid, e.g. ice to liquid water, melting ice cubes or snow flakes.
Condensation - gas to liquid, e.g. water vapor (gas) to liquid - water vapor in air (humidity) condenses to form liquid droplets on the outside of a cold beverage glass on a hot humid day; or cloud formation in the atmosphere.
Evaporation - liquid to gas, e.g. liquid water on clothes evaporates as clothes dry on clothesline or in dryer
While water can sublime under certain conditions of temperature and pressure, it is less evident in everyday life. Carbon dioxide however is a more common example.
Sublimation - solid to gas, e.g. "dry ice" disappearing. The visible smoke associated with dry ice is most likely just condensing water vapor in the air as the solid carbon dioxide cools the air.

Are solar and lunar eclipses processed by the movements of the Earth and moon?
Explanation:
As the Earth rotates on its axis and revolves around the Sun, several different effects are produced. When the new moon comes between the Earth and the Sun along the ecliptic, a solar eclipse is produced. When the Earth comes between the full moon and the Sun along the ecliptic, a lunar eclipse occurs.
What happens to the atoms that make up hydrogen fuel as it burns?
Answer:
When hydrogen fuel burns, its atoms combine with oxygen atoms in the air, which creates a chemical reaction that releases energy in the form of heat and light. The hydrogen atoms lose their outermost electrons, becoming positively charged ions (protons). These ions combine with the oxygen atoms to form water molecules (H2O), which evaporate into the air as steam. Therefore, the atoms that make up hydrogen fuel ultimately become part of water molecules during the process of combustion.

Which type of selection is shown in the graph above?
A. Disruptive selection
B. Stabilizing selection
C. Disaster Selection
D. Directional selection
In the given graph, the Evolved Population is showing disruptive selection. Hence, the correct option is A. Disruptive selection.
Stabilizing selection is a form of natural selection where individuals with average phenotypes are more likely to survive and reproduce their number. In this selection, the population tends to maintain a stable phenotype. As shown in the graph, the population is maximum for the population having a moderate length of neck.
Disruptive selection is a type of natural selection where extreme phenotypes are preferred over average phenotypes, leading to an increase in genetic variation and the population becoming more diverse. In this type of selection, the population diverges into two or more distinct phenotypic groups. As shown in the graph, two ranges of the population are favored for having traits for extreme lengths of the neck.
