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.

c. earths continental crust is thicker than its lithosphere.

because, the lithosphere is the outermost layer of the earth/ 100 km thick and is defined by its machanical properties.the lithosphere contains oceanic and continental crust that varies in age and thickness across locations and geologic time. the lithosphere is the coolest layer of the earth in terms of temperature. the term lithosphere should not be confused with the use of "geosphere" which is used to indicate all of earth systems, including the atmosphere, hydrosphere   and biosphere. the surface of the earth can be divided into the continental crust and the oceanic crust.   the continental crust is made mostly of granite while the oceanic crust is made of basalt. the average thickness of the continental crust is 25 miles and the average thickness of the oceanic crust is 5 miles.   three types of rock, igneous, sedimentary, and metamorphic, make up the surface of the earth. that's why 3 option is preferable.
