Ethylene
Explanation:
Introduction
The growth and development of plants under varied environmental conditions determine agricultural production. The growth, development, and senescence of plant’s organs can influence crop production by modulating photosynthesis, nutrient remobilization efficiency, and harvest index (Paltridge et al., 1984; Jing et al., 2005; Iqbal et al., 2012). Phytohormones have been shown to increase growth and yield of plants. The phytohormone ethylene controls growth and senescence of plants (Reid, 1995; Lutts et al., 1996; Thompson et al., 1998; Pierik et al., 2006; Masood et al., 2012; Nazar et al., 2014). Ethylene is regarded as a multifunctional phytohormone that regulates both growth, and senescence. It promotes or inhibits growth and senescence processes depending on its concentration, timing of application, and the plant cell

Good Luck Studying :)
Answer: This is true for all parts of the surface of the Earth including the land and the upper parts of the ocean. The four natural resources; soil/rock, air, water, sun; constitute the major components of the physical environment.
Explanation:
Surface water is warmer than deep-ocean water. The deeper you go into the ocean the colder it is. This is because the warmth from the sun cannot reach the water near the bottom of the ocean.
