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
Answer:
Membrane proteins perform a variety of functions vital to the survival of organisms: Membrane receptor proteins relay signals between the cell's internal and external environments. Transport proteins move molecules and ions across the membrane.
Explanation:
they help transport some substances through the membrane.
Answer:
it is necessary to do the additional trials before conclusion
Explanation:
These additional trials should be the same fertilizer on different plants
Answer:
A hummingbird feeding: Mutualism
Explain Interaction: The hummingbird drinks the nectar from the flower and the hummingbird may help pollinate the flower.
I'm a bit confused by the plants on the floor one.
Plants on a Forest Floor: Competition
Explain Interaction: The plants on the forests floor compete with each other for the same resources. Both may not receive enough of those resources. Note: When I was around Middle School and High-school I was only taught mutualism, commensalism, and parasitism, so let me know if competition is not a choice your teacher gives you to choose from or wasn't taught to you
Flea bites human: Parasitism
Explain Interaction: The flea drinks the persons blood as food and the person is hurt. Flea bites can be itchy and become painful. Fleas may also also carry disease.
Clownfish in Anemone: Mutualism (although I hear some people say commensalism)
Explain Interaction: The anemone provides protection and a place to live for the clownfish. The anemone may eat bits of food left over from the clownfish.
