Answers
An electron transport chain (ETC) is a collection of protein complexes and other molecules that transfer electrons from electron donors to electron acceptors via redox reactions (both reduction and oxidation occur at the same time) and couple this electron transfer with proton (H+ ion) transfer across a membrane. The electron transport chain contains many membrane-bound enzymes.

Plants may control the quantity of water and solutes they contain by using guard cells, which use osmotic pressure to open and close stomata. Thus, option A is correct.
What is the major function of guard cell in photosynthesis?Guard cells adjust the efficiency of leaf gas exchange in response to shifting environmental factors, and changes in atmospheric CO2 concentration, light intensity, humidity, and the drought hormone abscisic acid regulate their turgor.
Stomata, which are pores in the plant epidermis, serve as passageways connecting the intercellular gas spaces to the outside world.
Each stomatal hole is surrounded by two guard cells, and variations in the turgor pressure of the guard cells control the pore aperture size.
Therefore, it allows the intake of gases necessary for photosynthesis.

Answers
Answer:
2
Explanation:
Erosion is when the soil that is on the top of the land gets washed away by moving water. Fertile soil can help in preventing erosion because there will be more plants on fertile soil. When something like grass or any plant grows, the roots will hold the soil together more firmly. Vegetation is an effective measure against land degradation.
Answer:
Soil is a renewable resource that can be used in a sustainable manner. Fertility of soil can be sustained by protecting topsoil from erosion and contamination. Because soil fertility is replenished by decomposition of organisms, it is necessary to ensure that the natural life cycle of plants and wild animals is not disrupted.

During the day, an area of high / low air pressure forms over water and a sea / land breeze occurs
Answers
Answer:
Explanation:
The specific heat of water is more than that of sand, thus air above land becomes hot quickly and rises up. The cold air above water then move towards land. This is called sea breeze.
A high air pressure area forms on the water during the day, resulting in the sea breeze. The sea breeze is when the wind flows from the sea towards the land during the day.
What is a sea breeze?
During this time, the earth receives sunlight, which raises the temperature of the atmosphere. Between the sea and the land, the land gets hotter in less time than the water by the sun's light, and this is because the water has a high heat capacity.
The water needs a lot of energy to raise the temperature, and this is due to the water's high specific heat, but in comparison to water, the land has a low specific heat, so it gets warmer quickly. As a result, the air present on the land gets lighter and goes up. As a result, cooler air flows from the sea to the land, causing the sea breeze.
As a result, during the day, a high air pressure area forms over the water, resulting in a sea breeze.
