ANTONII [103]

Answer:

Xeromorphic adaptation is a type of adaptation which helps the plant body to retain water in dry environments.

Xeromorphytes are those plants having Xeromorphic adaptation. These plants adapt certain characteristics which enable them to store more water and lose less water.

JulsSmile [24]

<u>Answers</u>

-Worldwide sea level increased

-river plains drowned

<u>Explanation</u>

Glaciers are large blocks of ice and with all the ice melting the water levels rose worldwide. <em>(Correct Answer)</em>

When sea levels rose it caused river plains to be flooded. <em>(Correct Answer)</em>

Glaciers are made from freshwater so when they melt the salinity in estuaries does change. <em>(Not a correct Answer)</em>

Erosion definitely affected river valleys. Alpine glaciers create valleys and even help erode valleys. With Alpine glaciers melting this slows the process of that erosion and with them melting the river valleys will eventually flood. <em><u>(Not a correct Answer)</u></em>

I hope this helps!

What structure allows gases to enter a leaf
DanielleElmas [232]
Heyo. c:

The only way for gases to diffuse in and out of the leaf is through small openings on the underside of the leaf, the stomata.  These stomata can open and close according to the plant's needs.  The tissues of the leaf inbetween the epidermal cells, into which gases diffuse from the stomata, are called mesophyll.
