A cell wall is not an impenetrable fortress around the delicate plant cell. ... Molecules can also pass through the spaces within the cell walls, avoiding the cells completely (apoplastic pathways). It is great that nutrients can move from cell to cell, but there is also a problem with all the holes. Cells can lose water. If you want a really good and simple answer you can search it up in google

how does the earth evlove around the sun while the moon evlolves around the earth with out those two planets colliding
ICE Princess25 [194]

Answer:

This is a rather complicated thing to explain so I'll try my best. To put it in simple term the sun has whats called a SOI (sphere of infleunce) and anything inside of this is effected by the gravity of that planet or sun in this case. The earth is inside of this sphere of influence. The earth has a constant velocity that is making it move away from the sun but since it's in the suns SOI the path in which the earth moves is changed in a way that causes it to spin around the sun. The same thing is happening with the moon. I'm not 100% sure on this but I think the reason the moon does not just fly away towards the sun is because it is closer to earth and is more effected by earths SOI. Hope this cleared things up for you.

Approximately 300 million years ago, there were not separate continents, only one giant super continent that we call Pangaea. Over time, scientists realised that the Earth's outer shell slides over the inner mantle through plate tectonics. Around 200 million years ago, Pangaea began to break up through the process of continental drift. Gondwana, incorporating present-day <span>Africa, South America, Antarctica, India and Australia, split from Laurasia (Eurasia and North America).

Irrigation is an artificial technology that helps to obtain water and thus recover the loss in extensive (wheat) crops.

<h3>What is irrigation?</h3>

Irrigation is a technology based on the artificial supply of water to recover crops from drought conditions.

Genetic modification may also help with drought conditions by inserting into the genome of the target species gene sequences associated with hydric stress (e.g., a protein channel to close stomata at night).

In conclusion, irrigation is an artificial technology that helps to obtain water and thus recover the loss in extensive (wheat) crops.
