Answer:
phloem
Explanation:
In plants that bring the food made of leaves to all the other areas of the plant, Phloem is also known as bast. Phloem is made of different cells, called sieve channels, phloem fibers, complementary cells and parenchymatic phloem cells. Primary phloem consists of the epidermal cells of root and shoot tips (zones of new cell production), either of the propellant, the cells of which ripen before elongation, or the metaphloem in which the cells mature after elongation, during development.
Answer:
lateral inhibition in the retina
Explanation:
Horizontal cells are in contact with photoreceptor cells through the synapse. One photoreceptor forms an excitatory synapse with horizontal cell in the adjacent regions of the retina while the horizontal cell forms an inhibitory synapse with another photoreceptor.
Hence, as one photoreceptor activates the horizontal cell, the horizontal cell, in turn, inhibits the other photoreceptor cell and thereby reduces the quantity of neurotransmitter released at the bipolar cell. In this way, horizontal cells transmit lateral inhibitory stimulus to the photoreceptor which in turn improves the contrast at the edges of the object.
Sugar is what yeast needs to “wake it up” or break its dormancy.
Answer:
We now have technology that can take dna residue from fingerprints and compare it to dna of possible suspects to find the culprit. Other technologies involve running simulations to find where a bullet was shot from at what distance.
The greenhouse effect traps heat near the surface and raises the temperature, just like a blanket. :)
