Working in a lab means working under controlled environment. If in the generation 1 and generation 3, the number of bird’s increases or decreases in number, the possible conditions for this would
- The amount of food increased or decreased
- If a flock’s beak type made it easier to pick up the available food, the flock grows and vice versa
Justification: if the beak type for generation 1 makes the food intake easier, it will grow which ultimately decreases the food for the generation 3 which has un-supportive beak type.
So given the suggested food chain of algae-snail-sunfish-heron we can conclude that this food chain is heavily dependent on the process of photosynthesis.
The algae is the only of the organism that are directly dependent of the photosynthesis for their survival, while the snail, sunfish, and heron, and indirectly dependent on it.
Since we are talking about a food chain, in essence it means that all organism are connected through one another. So the algae perform photosynthesis for its own survival, the snail is using the algae is a food source, the snail is later eaten by the sunfish, and the sunfish goes on the menu of the heron.
If the algae, by some scenario, are not able to perform photosynthesis, than they will die off, and if they die off, than the snail will die off because of lack of food, if the snail dies off, along with it dies off the sunfish because of lack of food, and if the sunfish is out of the scene, the heron goes as well.
So we can conclude that the process of photosynthesis is of crucial importance for the survival of all four species, be it directly or indirectly.
<span>A sample that is large and randomly selected<span> is most likely to yield generalizable results. A large and randomly selected sample shows the real diversity of the population with little relevance of bias within the findings and produces generalizable results. Also, the results from the sample gives accurate representation of the larger population and are easy to use.</span></span>
D because they have the same materials but different structure which mean different functions
Water escapes from the pores in plant leaves because of evaporation. This water is what keeps the vacuoles in the cells full and shaped, so the vacuoles are like deflating water balloons
