Answer:
C) The continents were once connected.
Explanation:
All the continents were once part of the super-continent called Pangaea. Continental drift split it into fragments and led to the formation of the present-day continents. Since all the continents were connected, some of the cacti native to tropical western Africa must have been carried to present-day America.
The cacti populations present in America and tropical western Africa accumulated genetic variations to get adapted to the prevailing environmental conditions. Separation of continents by continental drift led to their geographical isolation and prevented any interbreeding between the populations. Over generations, the cacti present in two continents evolved into separate species.
Answer:
Chloroplasts are very similar to mitochondria, but are found only in the cells of plants and some algae. Like mitochondria, chloroplasts produce food for their cells. Chloroplasts help turn sunlight into food that can be used by the cell, a process known as photosynthesis
Answer:
The correct answer is: Species with limited resources usually exhibit a <em>logistic</em><em> </em>growth curve
Explanation:
In ecology, logistic growth refers to the phenomenon where the growth rate of a population decreases as the population reaches its carrying capacity (the number individuals that an environment can support without facing degradation). To put it simply, when a certain species has limited resources available to them, as they reach their carrying capacity, the population of that species will decrease due to death caused by lack of resources for consumption. The attachment shows what logistic growth looks like when plotted on a graph.
