Answer:
D) K being transported out of the guard cell.
Explanation:
The movement of water in the terrestrial plants is a very important factor as each cell of the plant require water to survive.
The movement of water is influenced by many physical, chemical and process going on in the plants like transpiration and stomatal opening and closing.
Water posses adhesion and cohesion properties which allow the water molecules to form a bond with other surface and with each other respectively. This allows the movement of water in the xylem by a process called capillary action.
The evaporation of water creates a pressure on the plant to absorb water from the soil but when potassium ions move out of the guard cell of stomata, the guard cells lose turgidity and stomata gets closed.
Thus, Option-D is correct.
Answer:
high clean-energy startup costs
Explanation:
Protecting the environment means improving its sustainability and reducing pollution to the barest minimal. This utterly means terminating every activity that contributes to pollution in the environment, including the source of energy. The most widely used source of energy is the non-renewable source e.g. coal, fuel, etc.
These source of energy, however, release pollutants in form of greenhouse gases, into the environment. One way to eliminate the use of non-renewable source of energy is to adopt the use of renewable sources e.g. solar energy, wind etc. However, one major setback to doing this is the high production cost involved.
Although these sources of energy (renewable) are referred to as green or clean, but they have really expensive startup costs and are unaffordable most times.
Answer:
Probably because they just need air to being able to live and have air going in and out like carbon dioxide and getting rid of used air.
DNA Polymerase is the enzyme that joins individual nucleotides!
