The diagram shows the growth of a plant over several months. Which is the best label for the arrow in the diagram?

Hormones in the soil help fruits develop and ripen.
Hormones in the soil allow seeds to germinate.
Hormones in the plant allow seeds to germinate.
Hormones in the plant help fruits develop and ripen.

Hormones in the plant help fruits develop and ripen.

Explanation:

The growth of plants is regulated by "plant hormones." There are primarily 9 plant hormones and these are: ethylene, salicylic acid, cytokinins, auxin, abscisic acid, gibberellins, strigolactones, nitrous oxide and brassinosteroids. Fruit-ripening is highly associated with "ethylene." These hormones also affect the yield production.

The image above shows how the two fruits became bigger from left to right. This portrays the fruits' ripening.

estuaries are the partially enclosed coastal bodies of brackish water formed at the mouth of sea where river meets an ocean. it is a transition zone between river and sea water so estuaries are influenced to both marine environment such as tides, waves and to riverine such as flow of fresh water and sediments. the mixing of sea and fresh water provide high level of nutrients, making estuaries a high product habitats.

many estuaries suffers degradation from a variety of human activities like erosion from deforestation, overgrazing, overfishing, drainage and eutrophication.

so from the above statement answers will be

1. false as estuaries are formed due to both brackish and freshwater.

2.true, due to high productivity estuaries are breeding ground for many marine species.

3. direct and indirect activities of man that contribute to pollution and deposition of sediments.
