Well, they are made of cells, they obtain and use energy, they grow and develop, they reproduce, they respond AND adapt to their environment, c:
Bc it eats the waste that is inside of the sewer pipes
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.
Answer:
Electron Microscope
Explanation:
In contrast to light microscopes, electron microscopes use a beam of electrons instead of a beam of light. Not only does this allow for higher magnification and, thus, more detail, it also provides higher resolving power. The method used to prepare the specimen for viewing with an electron microscope kills the specimen. Electrons have short wavelengths (shorter than photons) that move best in a vacuum, so living cells cannot be viewed with an electron microscope.
The processing of color begins with the activation of cells sensitive to one of the three colors red, green, or blue, followed by the activation of the opponent process cells. Humans have three cones which has photo-pigments that would be able to sense the different parts of the spectrum. Each of the cone would tune to their respective wavelengths. The long wavelengths corresponds to the color red, middle wavelengths is green and short wavelength for blue.
