Answer:
disturbance has destroyed population in a community
Explanation:
The secondary succession occurs after there has been some disturbance that has manged to badly damage or destroy the populations in a community. This basically means that after some catastrophic event that happened to a certain population or populations, other species moved in to colonize the freed space. There are countless examples of secondary succession in nature, and one of the best is when there is a strong volcanic eruption. The volcano manages to destroy the population of plants and animals in its close surroundings, but after the eruption ends, the space starts to be colonized by new plants and animals step by step until they create a new well functioning community.
Two populations are said to be isolated if there is no longer any Gene Flow between them.
Answer:
a) when cells are small the movement of food and waste can be efficiently handled by the cell membrane
Explanation:
Cells need to get their nutrients and waste in and out of their cell membrane every quickly. Cells are hard workers anyway! The other options also don't make much sense. The cell shape doesn't mean much to their function, and size doesn't impact shape. The cell's internal parts (mitochondria, vacuole, etc) don't support the cell membrane, they have their own functions to focus on. Cells don't work together in tissue but they can interact with each other when needed.
The correct answer is the option B) It does not allow for the accumulation of glycogen and, therefore, limits the organism's mobility.
Explanation:
In cellulose and chitin the arrangement of glycogen in in alternate arrangement that provides the support to the plants that makes it strong and the limits its mobility.
If plants lac their special arrangement of the glycogen in chitin and cellulose the water will flow in and it will not be stand upright.
Thus, the correct answer is option B) It does not allow for the accumulation of glycogen and, therefore, limits the organism's mobility.
