Reverse faults occur at transform boundaries and Strike-slip faults occur at divergent boundaries.
Sudden movement along Earth's fault lines causes earthquakes. The motion releases "elastic strain" energy that has been accumulated inside the form of seismic waves, that travel through the Earth & cause the earth to tremble. A mid-ocean ridge, or underwater mountain system created by plate tectonics, is what is referred to as the Mid-Atlantic Ridge (MAR). The "elastic rebound theory" for earthquakes refers to this steady buildup & release of stress and strain. Reverse faults happen at convergent borders whereas normal faults happen at divergent boundaries.The abrupt elastic rebounding of previously energy stored is what causes most earthquakes. Tectonic plates, which are huge chunks of the lithosphere of the Earth, split away from one another during the geologic process of seafloor spreading.

Coyotes are predators of rabbits, and rabbits eat grass. An ecosystem experiences an increase in the size of its rabbit population. Which change will help the ecosystem maintain homeostasis?
Answer:
Explanation:
An increase in the rabbit population can result in an increase in the coyote population since coyotes prey on rabbits. This increase in the coyote population can then lead to a decrease in the rabbit population as they become preyed upon.
To maintain homeostasis in the ecosystem, one change that can help is the introduction of a predator of the coyote population. This can help control the number of coyotes and reduce the pressure on the rabbit population.
Another change that can help maintain homeostasis is the introduction of a new food source for the coyotes. This can reduce their dependence on rabbits and lower the pressure on the rabbit population.
Alternatively, the ecosystem may adapt naturally over time by altering the dynamics between coyotes and rabbits, such as increasing the rabbit's ability to evade predators or reducing the coyote's population through other means like disease or natural disasters. However, such changes may take longer to occur and may not always result in a balanced ecosystem.

c. maltose was broken down into starch by the acidic environment
benedict’s reagent reacts with water
Tube 3 did not have starch or amylase in it but still it showed a positive reaction with benedict's reagent because benedict's reagent reacts with maltose. The option is A.
Benedict's reagent is used to test for the presence of reducing sugars such as maltose, glucose, and fructose. This reagent is composed of copper sulfate, sodium citrate, and sodium carbonate. When a reducing sugar is present, it reduces the copper sulfate to cuprous oxide, which causes a red precipitate to form.
The positive reaction in tube 3 even though it does not contain amylase or starch is due to maltose presence, which is broken down from the starch in the previous tube into maltose by the amylase, which causes the benedict's reagent to show a positive reaction.

a key role of psi is to produce high-energy electrons that are used to make
The production of high-energy electrons by Psi plays a crucial role in photosynthesis, providing the energy necessary for the synthesis of ATP and NADPH, which are essential for the survival of plant cells.
Psi (Photosystem I) is a photosynthetic protein complex found in the thylakoid membranes of chloroplasts in plant cells. One of its key roles is to produce high-energy electrons that are used to make ATP (adenosine triphosphate), the primary energy currency of cells, and NADPH (nicotinamide adenine dinucleotide phosphate), an electron carrier molecule that is used in various metabolic processes.
In photosynthesis, light energy is absorbed by pigments called chlorophylls, which are located in the thylakoid membranes of the chloroplasts. This light energy is then converted into chemical energy in the form of high-energy electrons, which are passed through a series of electron carriers, including the Psi complex.
When light energy is absorbed by chlorophylls in the Psi complex, it excites electrons to a higher energy state, which are then transferred to an electron acceptor called ferredoxin. These high-energy electrons are then used to reduce NADP+ to NADPH, which can be used in various metabolic processes such as the synthesis of carbohydrates.
In addition, the movement of these high-energy electrons through the electron transport chain in the thylakoid membrane generates a proton gradient, which is used to drive ATP synthesis through a process called photophosphorylation.
