Answer:
lithosphere
Explanation:
is found under the oceans and formed at spreading centres on oceanic ridges, which occur at divergent plate boundaries.
Complete Question:
Which of the following is a process that changes the composition of rocks from one material to another?
Group of answer choices.
A. Erosion
B. Deposition
C. Physical weathering
D. Chemical weathering
Answer:
D. Chemical weathering
Explanation:
Weathering can be defined as the physical and chemical breakdown of rock into smaller pieces called sediment. Weathering can be classified into two categories namely;
I. <u>Physical weathering</u>: it is the process of breaking rocks into pieces without affecting its chemical composition e.g temperature, abrasion and frost action.
II. <u>Chemical weathering</u>: it is the process of breaking rocks into pieces by chemical action which leads to changes in its chemical composition e.g carbonation, hydration, plant acid and oxidation.
This ultimately implies that, chemical weathering refers to a process that changes the composition of rocks from one material to another. Some of the by products of chemical weathering are clay minerals, quartz, feldspar, muscovite, etc.
<span>The correct answer is cGMP.</span>
<span>cGMP, during the dark (when there are no stimulations of photoreceptor cells), reaches high intracellular levels. When the light stimulation occurs cGMP levels decrease because it is converted to GMP by phosphodiesterase. Phosphodiesterase is activated by transducin which is activated by excited rhodopsin (contains photopigment).</span>
<span>
Low levels of cGMP block the cGMP gated ion channels and that prevents the entry of Na and Ca. Because of that membranes becomes more negative, hyperpolarization occurs and this creates a signal for the next cell.</span>

▹ Answer
<em>Light, carbon dioxide, and water</em>
▹ Step-by-Step Explanation
ATP requires light, carbon dioxide, and water to convert certain molecules of water into oxygen which is then converted into energy particles known as ATP.
