Perhaps the most significant factor that affects the biogeochemical cycles in the terms of human involvement is global warming, which disrupts natural cycles on various levels.

The other answer is incorrect, despite being verified. The correct answer is A. increased eutrophication caused by high levels of nitrogen and phosphorous.

I took a quiz and got this question wrong because I listened to the verified answer.

Describe the effect that sickle cell anemia has on the sedimentation rate (sample 3. why do you think that it has this effect?

Eva8 [605]

Sickle cell anemia is a genetic condition that distorts the shape of the hemoglobin. This reduces the capacity of the red blood cells to carry oxygen. Another effect is that the distorted red blood cells come together forming a heavy and compact collection of cells that can block the flow of blood. The sedimentation rate is increased by sickle cell anemia.

Why would chemical weathering affect the kinds of minerals in soil as the soil is formed??

Vilka [71]

Process by which the internal structure of a mineral is altered by the addition or removal of elements. Change in phase (mineral type) and composition are due to the action of chemical agents. Chemical weathering is dependent on available surface for reaction temperature and presence of chemically active fluids.

The noncyclic pathway is a FLOW of electrons from water, to photosystem II, to PHOTOSYSTEM I to NADPH. Energy is released as ELECTRONS move through the first electron transfer chain. This energy pumps HYDROGEN IONS into the thylakoid compartment, and then they power the formation of ATP as they flow back out. Sunlight provides the energy needed to keep this cycle going.

----------------------------------------------------------------------------------------------------

Luminous energy is trapped by chlorophyll in Photosystem II.
When the pigment molecules absorb light, electrons provided by water molecules get in a higher energy level.
The excited electrons go through the electron transport chain from Photosystem II to a less energetic level in photosystem I.
<em>When the excited electrons leave photosystem II, they are replaced by new electrons extracted from the water molecules. </em>
Luminous energy absorbed move the electrons from the photosystem I to another electron acceptor, from where they get transported again and used to produce NADPH molecules.
<em>When electrons leave Photosystem I, they are replaced by new electrons coming from photosystem II. </em>
When the water molecule breaks down, hydrogen ions remain in the thylakoid lumen, from where they are pumped to the stroma by the ATP synthase.
The released energy is used to produce ATP molecules.
Hydrogen ions go back from the stroma to the thylakoid compartment.

The final products are oxygen, ATP, and NADPH.
