The properties of the gas in each test tube can be used to tell whether the gases are the same or different, because depending on the substance, chemical reactions will occur.
What do you think might happen when a gas is exposed to a small flame?This happens in the flame test, which is based on the fact that when a certain amount of energy is supplied to a certain chemical element (in the case of a flame, energy in the form of heat), some electrons in the last valence shell absorb this energy.
Moving to a higher energy level, producing what we call an excited state. When one of these excited electrons returns to the ground state, it releases the energy previously received in the form of radiation.
With this information, we can conclude that the properties of the gas in each test tube can be used to know if the gases are the same or different, because depending on the substance, chemical reactions will occur.

What is the smallest lava fragments produced by an explosive eruption called?
Explanation:
rock fragments between 2 and 64 mm in diameter they were ejected from a volcano during explosive eruption
and that is called LAPILLI
A pyroclastic grain, lapilli is the smallest lava fragment produced by an explosive eruption.
What is a pyroclastic grain?Any volcanic piece that was propelled through the air by volcanic activity is known as a pyroclastic. A pyroclastic eruption is one in which fountains or explosions make up the vast majority of the activity. Lapilli, lava bombs, and lava blocks are some pyroclastic grains.
Pyroclasts include volcanic bombs, cinders, and ash. Pyroclasts are created either directly from the magma or by removing solid fragments from the conduit's walls, which are typically found close to the surface. Most parks with volcanoes or volcanic rocks have pyroclastic rocks that can be seen.

What happens to energy from the Sun when it reaches Earth
Answer:
The energy from the sun that reaches Earth’s surface is mostly “shortwave” radiation – mostly visible light. This energy passes freely through the atmosphere and is absorbed by Earth’s surface. The surface warms from the energy input, and some of its heat projects back to the atmosphere as infrared radiation.
Explanation:
Energy released from the Sun is emitted as shortwave light and ultraviolet energy. When it reaches the Earth, some is reflected back to space by clouds, some is absorbed by the atmosphere, and some is absorbed at the Earth’s surface. … Shortwave radiation reflected back to space by clouds.

Mary loved having her goldfish tank in her office. She said watching the fish swim around was calming to her on stressful days. Mary thought that if 2 goldfish in her tank could make her less stressed then certainly 8 goldfish would be even better. After three days of having 8 goldfish in her tank, she noticed 5 of the fish began to sink to the bottom of the tank becoming less active than the remaining 3. A few days later the 5 sick fish died and the 3 remaining fish thrived. Use the data to help you choose three reasons the carrying capacity of the fish tank wasn’t able to accommodate all 8 goldfish.
Answer: I think that the reason to this is because the oxygen abundance was too low, the competition for food and other resources was too high, so there could be fish the would be filtered out and be killed.

Which region of the human alimentary tract has both the largest population of bacteria and the greatest species diversity
The region of the human alimentary tract that has both the largest population of bacteria and the greatest species diversity is the the colon.
The normal flora of the alimentary tractNormal flora are those microorganisms that resides in a living organism without causing it harm or diseases.
These normal flora become established in different parts of the body from birth such that the normal flora found in the mouth is not the same as the one found in the colon of the alimentary tract.
From research works, the large intestine (colon) is known to contain 100 billion per milliliter of fluid culture.
The massive numbers of bacteria in the large intestine (colon) creates a great special variation in the flora. The streptococci and lactobacilli found in the colon often adhere to cells by means of capsules surrounding the bacteria.
Therefore, the region of the human alimentary tract that has both the largest population of bacteria and the greatest species diversity is the the colon.

What does fossil evidence show about evolution?
Answer:
Answer below
Explanation:
Fossils provide physical examples of what organisms have looked like over time. For example, we can look at giraffes over time, who have evolved to have had long necks. When we look as fossil records of giraffes and similar species, we see that the longer ago that animal lived, the shorter their neck was, and as time progresses, the neck gets longer. However, we also see that in general the giraffes with longer necks, regardless of time period, will have lived longer and healthier lives (we can usually tell this just by how big the fossil is), as with longer necks the animal was able to reach more food and live longer. That giraffe then reproduced and shared their longer neck traits, while those with genetic markings to make their necks shorter will have died before reproducing. Therefore, we can see all forms of evolution through fossils.

How do vaccines work if the pathogen in them is dead?
Vaccines work by stimulating the immune system to recognize and defend against specific pathogens, such as viruses or bacteria, that cause diseases.
How vaccines workThere are different types of vaccines, including those that contain dead or inactivated pathogens.
When a vaccine contains dead or inactivated pathogens, it means that the pathogens have been rendered non-functional or unable to cause disease. However, they still retain their antigenic properties, which means they can trigger an immune response.
When the dead or inactivated pathogens are introduced into the body through vaccination, the immune system recognizes them as foreign invaders.

7. What is the general relationship between the color of a filter/solution and the light that it absorbs?.
Answer:
A filter will absorb its complementary color of light. So a yellow filter absorbs blue light since blue is across from it on the color wheel. Whatever light is not absorbed will be transmitted; so yellow filters transmit red and green light (if incident upon it), also known as yellow light.
hope its helpful
A filter will absorb light of the complementary color. As blue is opposite yellow on the color wheel, a yellow filter will therefore absorb blue light.
What is filter?A filter is a translucent substance that lets some colors flow through while absorbing others.
Color can only be produced by light. Color pigments (paints, dyes, or inks) display color by reflecting the light that isn't absorbed while absorbing some portions of the light spectrum.
The same principles govern how color filters function, with some color wavelengths being absorbed and others being transmitted.
Only yellow will pass through a yellow color filter while all other colors are absorbed. Therefore, if blue light is shone on a blue object through a blue filter, the object will still reflect blue and thus appear blue.
Therefore, A filter will absorb light of the complementary color. As blue is opposite yellow on the color wheel, a yellow filter will therefore absorb blue light.
