When a drug binds to a receptor in the body , the receptor is activated or inactivated.
Molecules such as hormones, drugs or neurotransmitters that bind to a receptor are called ligands. The binding can be specific and reversible. A ligand may activate or inactivate the receptor; activation may increase or decrease a particular cell function. Each ligand may interact with multiple receptor subtypes.
The right answer for the question that is being asked and shown above is that: "Secondary Succession" Assuming this land was once a farmer’s field with previously established vegetation, the process that does this photograph best represent is secondary succession.
An approach that uses passive solar heating instead of electricity for businesses and homes is known as A. Daylighting.
<h3>What is daylighting?</h3>
This is the illumination of buildings with natural light through the practice of placing reflective surfaces so that sunlight can provide effective internal lighting.
Solar heating is the use of sunlight to heat water or air in the buildings using radiant light and heat which is harnessed using a range of technology such as solar power to generate electricity.
Hence, we can see that neither weatherizing, green roofing nor cool roofing is the answer because they do not deal with providing passive solar heating, but daylighting uses passive solar heating.
Therefore, the correct answer is option A.

I believe that plant hormonal control differs from animal hormonal control in that there are no separate hormone-producing organs in plants as there are in animals. Hormones regulate cellular processes in targeted cells locally and moved to other locations, in other function parts of the plant. Hormones also determine the formation of flowers, stems, leaves, the shedding of leaves, and the development and ripening of fruit. Plants unlike animals they lack glands that produce and secrete hormones and instead each cell is capable of producing hormones.
