As altitude increases, air pressure __________ (increases, decreases, or stays the same). This is a(n) ________(direct, indirect
lions [1.4K]

Answer:

The correct answer is - decreases. direct.

Explanation:

Altitude is a distance measurement of distance in a vertical manner or how high something from the sea level. It helps in the height of the mountains and different places.

Air pressure and altitude are the two factors that are in direct relation as the air pressure decreases with the increase in altitude. the gases present in the higher elevations are fewer than the sea level.

Question 1: Biodiversity and Ecosystem Health (20 points) a) Describe two ways of measuring biodiversity. Explain the relationsh
fredd [130]

Answer:

explanation below

Explanation:

A) Biodiversity is simply known as the number and variety of organisms found in a definite environment or region.  Scientists have devised several ways of measuring biodiversity and the methods to be used depend on the type of organisms they are to count.  

Canopy fogging – one of the ways of measuring biodiversity, has remained an effective way of obtaining details about the biodiversity of insects.  It involves the act of spraying  low dose of insecticides on a tree top, and when the insects fall from the trees, they are being collected on a large screen, that looks like a funnel.  

Transact sampling is another way of measuring biodiversity and this time, with a transact line. The transact line is usually a measuring tape or rope that has been marked at set intervals.

b) Ecosystem stability is the ability of the ecosystem to maintain its steady state, even after it has experienced stress or disturbances.  The biodiversity of an environment makes huge impact on the ecosystem stability in that particular area. It has been known that certain areas that have high levels of species and genetic diversity, are more likely going to an ecosystem that is complex, with varying food webs and biotic interactions. The increase in this complexity makes it more likely that the ecosystem of that area will rightly move back to a stable state whenever disturbances are experienced.

There are evaluated scientific evidence that shows that reduced biodiversity affects the transmission of communicable disease in agricultural crops, animals and humans. Loss of biodiversity usually increases susceptibility to diseases in plants and humans.

During photosynthesis
Eduardwww [97]

Answer:B

Explanation:

The first stage of photosynthesis is the light reaction which occur in the thylakoid membrane of the chloroplast. Solar energy of light captured by chlorophylls, and is used to produce high-energy electrons of which in a series of reactions produces ATP and NADPH.

In the dark reaction of photosynthesis the ATP and NADPH are used to reduce CO2 to produce sugar
