1: What gases are used and expelled by photosynthesis and respiration?

2: Where are the largest concentration of ozone and what value does it have?

3: What happens to the surface of the earth when there is an increase in greenhouse gases?

Answer:

1 Photosynthesis uses CO2 and expels O2 and the reverse for respiration

2. stratosphere where ~90% of it is

3. Less infrared radiation is able to escape from the earth into space and that infrared radiation hits the GHG gases and the radiation is turned into kinetic or heat energy trapping which warms up the earth

Explanation:

Answer:

1. Used by Photosynthesis: CO2  Expelled: O2

Used by Cellular respiration: O2 Expelled CO2

2. Most ozone (about 90%) is found in the stratosphere, which begins about 10–16 kilometers (6–10 miles) above Earth's surface and extends up to about 50 kilo- meters (31 miles) altitude. The stratospheric region with the highest ozone concentration is commonly known as the “ozone layer”

3. The surface of the earth heats up

Which statement about adaptations is correct as it pertains to the scientific theory of evolution?
A. Adaptations, which are learned behaviors, allow organisms to learn how to survive in any environment and predict environmental changes in order to prevent
extinction of the species.
B. Adaptations, processes in which a single surviving organism chooses to change its traits, allows a species to redevelop variability and to increase in numbers.
O C. Adaptations, which are beneficial genetic traits, are critical to the survival of a species by providing alternative ways to adjust to a changing environment and prevent
extinction
O D. Adaptations, processes in which an organism physically changes its environment, provides a way for a species to decrease its numbers to prevent competition.
