Some plants exhibit a behavior called thigmotropism that causes the plant to grow or move in response to touch or contact. climbing vines use this behavior to grow tendrils that curl around other plants for support. what is the most likely reason a climbing vine would evolve this ability? a. to ensure seeds are widely dispersed c. to grow roots needed to absorb water and nutrients b. to absorb water and food from the host plants d. to grow high off the ground in order to maximize sunlight exposure

The right answer is d.to grow high off the ground in order to maximize sunlight exposure

Explanation:

Thigmotropism is a directional grow in response to a touch stimulus. As a result the plant which exhibit thigmotropism presents pronounced vertical grow and reduced lateral grow. Climbing vines grows around other plant so, the support plant intercept most of the incident radiation. As climbing vines needs sunligth to photosynthesize they grow in vertical direction. So, the principal cause for this evolvement is to maximize sunlight exposure.

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.

thats not even an aswer choice
