Answer:The structure of plant roots, stems, and leaves facilitates the transport of water, nutrients, and photosynthates throughout the plant. The phloem and xylem are the main tissues responsible for this movement. Water potential, evapotranspiration, and stomatal regulation influence how water and nutrients are transported in plants. To understand how these processes work, we must first understand the energetics of water potential.

in pea plants, purple flowers (p) are dominant over white flowers (p). Show the cross between two heterozygous plants
Ostrovityanka [42]

Answer:

       <em>P      p</em>

<em>P</em>    PP   Pp

<em>p    </em>Pp    pp

PP=Homozygous purple

Pp= heterozygous purple

pp=homozygous White

Explanation:

I tried to type out the cross. The bold letters are the heterozygous  plants that you are crossing. and the normal letters are the offspring of the two heterozygous parents being crossed. Heterozygous means they are different alleles. Homosygous means the same alleles are present.

heterozygous= Pp

Homozygous= PP or pp

I hope this was the answer you were looking for!

What is the TECTONIC CYCLE? Briefly summarize it.
igomit [66]
<span>In simple terms, heavier plates get melted in Mantle, become lighter in form of lava and create new plates. As we have a re-cycle or the convection currents, there are cycles in lithosphere.
There is continuous push and pull happening on and below the Earth. When a plate is subducting on one end, there has to be some reaction on the other end, right?
Ridge is developed on the other side, where the same material which has been melted on the subduction side helps to fill the gap at ridge side. Since the material is just transfered from heavy to light, and reused in that cell, it is called a cycle.
****Hope this helps!!! also...... please take a look at my profile, if you are a girl who dances.... WE NEED VOLUNTEERS!!!! Thanks! Merry christmas!!! and if possible, pick my answer as brainliest!!
