Pods of certain plants such as gorse and pansies have a way of flinging their seeds when ripe in every direction with considerable force. The thing that helps these seeds disperse is first and foremost the mechanical force itself used to catapult the seeds.
As they ripen, the seed pods gradually lose moisture, building up tension in their cells and subsequently in the pod as a whole. The structure inevitably fails gradually and during a hot day it gives way altogether due to heat stress and triggers an explosion firing the seeds with appreciable force away from the parent plant almost like a projectile for up to 100m (300 ft) away.
It is important to note that plants which use this explosive method or ballistic dispersal as it is also called tend to have seeds that are generally large and too heavy to be carried by the wind unlike those of plants such as dandelions which are light enough for wind dispersal. Therefore gorse and suchlike plants employ ballistic methods to ensure their seeds travel as far away from the parent plant as possible.
Answer: D. Adaptations help organisms survive and reproduce in a particular environment.
Explanation:
An adaptation can be define as the changes that occur in the behavior, structure and physiology of the organism so that organism become suited to survive and reproduce in the adverse environment. Adaptation results due to evolution of the living organisms through the process of natural selection as a result of interaction of the organism with the changing or unsuitable environment.
4 the organism would not produce new cell idk if im right
Answer:
Explanation:
The correlation between sea surface temperature and water vapor is that both are driven by seasonal changes. They both increase in the hemisphere during summer. Seasonal changes in water vapor are, however, more evident across the land, largely due to changes in land surface temperature.
In late Paleozoic and much of the Mesozoic era the region was affected by a series of orogenies (mountain-building events) that deformed western North America and caused a great deal of uplift. Eruptions from volcanic mountain ranges to the west buried vast regions beneath ashy debris.
