Answer:
water motion that is non-linear in nature can cause natural disasters on shorelines.
Explanation:
these natural disasters could be on a small scale or a large scale depending on the strength of that movement of water. Rip currents and storm surges (uncommon) are two different types of hazards that can occur on the coast. In addition, a more dangerous case is a tsunami - which may be triggered by an earthquake - these are ocean waves traveling at a very high speed.
Hope that answers the question. Have a great day!
<span>To verify the purity of a
colony, a number of steps could be adopted. Pick the colony and dissolve it in sterile
water (approximately 5ml), streak in media again and incubate. Observe if it
produces pure colonies of the chosen organisms and if not, repeat the procedure
until pure colonies are produced. Additionally, one could perform additional tests
that categorize bacteria such as Gram staining. </span>

The complete question is :
The success of plants extending their range northward following glacial retreat is best determined by _____.
A) whether there is simultaneous migration of herbivores
B) their tolerance to shade
C) their seed dispersal rate
D) their size
Answer: The seed dispersal rate
Explanation:
The seed dispersal can be defined as the movement of the seeds away from the parent plant. The ability of the plant to extend is completely dependent on the ability of the plant to disperse its seeds.
Plants have very limited ability, they need vectors to carry its seed from one place to another.
The biotic and abiotic vector both are involved in carrying the seeds which helps in expansion of the trees.
hence, the correct answer is option C
