Every member of a particular species is found within a certain population living in a desert. The growth of this population is l
imited by the availability of water in the ecosystem. The population has many food sources available to it.
This species might become extinct if
OA.
a disease eliminated one of the population's food sources
OB
a new food source was introduced to the ecosystem
OC.
food became the limiting factor for the population.
O D.
a long drought caused water to become scarce.
A limiting factor is a resource that limits the growth of a population. The limiting factor for the population described in the question is water availability. This means that the carrying capacity in the ecosystem for this population is determined by how much water is available, no matter how much food, space, or shelter the population has access to. Since the population has numerous food sources, the elimination of one food source would not likely cause the species to become extinct. A long drought that caused water to become scarce, however, might lead to species extinction.
The choices can be found elsewhere and as follows:
A. mature leaves B. shoot apical meristem C. cell elongation zone <span>D. axillary buds </span> I think the correct answers are option B and D. It would be at the shoot apical meristem and the axillary buds that <span> a vascular plant would you expect to find totipotent cells. Hope this answers the question.</span>
Mitochondria are made from the process called binary fission. This is the cell division utilized by the prokaryotes. It also has circular DNA that is similar in both size and structure in prokaryotic cells. Mitochondria also has its own DNA different than the DNA found in the nucleus of a cell.
