Which gas is most effective in absorbing incoming harmful ultraviolet radiation in the earth's stratosphere before that radiation reaches earth's surface?
Answer:
Ozone (O₃) gas
Explanation:
In the Earth's stratosphere, oxygen gas (O₂) is combined with atomic oxygen (O) to form ozone gas (O₃). This is very important because ozone protects the life on Earth from ultraviolet (UV) radiation from the Sun. UV radiation is high-energy radiation, and it is very dangerous for living organisms. Ozone molecule (O₃) absorbs UV radiation and it breaks down by forming O₂ and atomic oxygen (O) again. In this way, it protects the Earth from nocive radiation.

related to HELP part c number 1
Answer:
Due to suitable environment of the equator.
Explanation:
Latitude is abiotic factor that has a great impact on the occurrence of fish species as we can see in the graph, the fish species increases as we go towards equator whereas decreases when we go away from the equator. This is because the climatic condition and temperature of water at the equator is suitable and warm so this suitable environment attracts more species to lives there.

What is the relationship between the masses of the objects and the gravitational force
between them?
I foron hotuen the two obiects in this
Answer:
They are directly proportional
Explanation:
The relationship between the masses of the objects and the gravitational force between them is such that both quantities are directly proportional to one another.
This is based on the Newton's law of universal gravitation.
The law states that "the gravitational force of attraction between two masses is directly proportional to their products and inversely proportional to the square of the distances between them".
So, the gravitational force is directly proportional to the masses of the two objects.

Please helpppp meee!!!!its a final
Answer:
C. mountain lion-consumer; bark beetle-herbivore
Explanation:
Food webs contain a series of inter-connected food chains. In a food web, organisms in different trophic levels feed on one another to obtain energy. Based on the diagram attached to this question, the roles of different organism is as follows:
- MOUNTAIN LION: This is a consumer i.e organism that feeds on other animals. This is the case as seen in the diagram that mountain lions are feeding on rabbits and Hawks.
- BARK-BEETLE: This is an herbivore because it feeds directly on the plants as seen in the attached image.
