Answer: They may be wind blown, rain splashed, carried by animals, or moved in soil or water. Almost all short-distance spread is through these natural dispersal mechanisms. In their home territory, short distance spread is rarely a problem because the resident plants and animals have evolved to coexist more or less peaceably.
Explanation:
Re-posting some old information I found on this website
<span>When a fungus infects a body, it attacks the host by destroying and often taking over cells. When a person has an allergic reaction (to anything) the substance triggers the body to send histamines and excess water to the affected area, swelling and closing the area to prevent infection. - Answer Provided by ChaoticPiece</span>
Overproduction of offspring, inherited variation, and the struggle to survive.
So: b, d, and e
There are a few different types of cell-cell interactions. Some of these interactions are meant for big molecules that enter and exit the cell called, endocytosis (entering the cell) and exocytosis (exiting the cell). For smaller particles like amino acids, water, ions and other solutes there are different types of direct contact between the cells called gap junctions.
Answer:
The movement of Xylem is unidirectional and phloem is bidirectional
Explanation:
The tension created by transpiration “pulls” water in the plant xylem, drawing the water upward in much the same way that you draw water upward when you suck on a straw.
Phloem transport is bidirectional because sucrose gets accumulated in the phloem tissue and absorbs water creating a high turgor pressure. ... Hence the water flows from regions of high turgor pressure to low turgor pressure and the direction can be upwards or downwards from the leaves based on the gradient.
