Guyss plz help me i will give yall extra pointss
Komok [63]

Answer:

The water is transported to the top most leaves (and rest of its parts) of a tall tree by three actions:

1) root pressure (osmosis)

2) capillary action (adhesion)

3) evapotranspiration (cohesion)

Explanation:

The trees contain a series of interconnected tissues (xylem and phloem) that act as network for transport of water and nutrients throughout the tree. The root pressure and capillary action push the water, while the transpiration from the leaves pull the water. The root pressure is generated by osmotic movement of water from soil to the root tissues. The capillary action is caused due to adhesion of water molecules. However, root pressure and capillarity is thought to support only few meters of water column. The rest of the water transport (esp. in tall trees) is attributed to negative pressure generated by evaporation of water from leaves. This negative pressure creates a vacuum and pulls the water from the roots.

Hope this helps.

What would happen without the magnetic field?
telo118 [61]

Explanation:

The Earth's magnetic field protects us by deflecting much of the incoming solar radiation. Without it, our atmosphere would be stripped by solar winds.

Satellites can and do suffer damage from solar storms, and without Earth's magnetic field, every electronic device could be exposed to high-energy particles from cosmic rays and the solar wind. If Earth lost its magnetic field, there would be no magnetosphere and no line of defense, even from weaker solar storms

What darwin never knew essay
Gelneren [198K]

Answer:

What Darwin Never Knew”, is a stunning time line that details the theory of evolution formed by Charles Darwin, and the recent advancements made that answers some of the questions he simply could not. Darwin 's theory explained why today there are 9,000 kinds of birds, 350,000 kinds of beetles, 28,000 kinds of fish, and at least 2 million kinds of living species and counting. Darwin figured out that all species are connected, and he also realized that species evolved and adapted, but he did not know how. Darwin made a five year voyage on The HMS Beagle that would change his life, and all life as a matter of fact, forever.
