Answer:
False
Explanation:
The hypotheses are conjectures, speculations, predictions about a certain phenomenon of nature and how it behaves. Hypotheses should be tested, which is usually accomplished through experiments.
Theories are well-founded explanations for describing events occurring in nature. They involve hypotheses already thoroughly tested, facts and laws.
This is because of the high specific heat capacity of water.

Answer:
Vacuole and Chloroplast
Explanation:
Vacuole and Chloroplast are not found in animals.
Vacuole function in the storage of food in plants. While chlotoplast is involved in the process of photosysthesis.
Answer:
Plant cells have cell walls and chloroplasts; animal cells do not. The cell wall surrounds the cell membrane, supports the cell, and gives the cell its shape. Chloroplasts capture energy from sunlight and convert it to chemical energy that the cell can use.
Explanation:
b) less than the number of carnivores
c) equal to the number of scavengers
d) none of the above
Answer:
Option D
Explanation:
In a balanced ecosystem, the flow of resource, food and energy must be adequate enough to fulfill the requirement of all.
In case if the population of deer is higher than the population of producers then the producers would not be able to meet out the requirement of herbivore deer. Hence, this option is incorrect
In case if deer population is less than the population of carnivores, all the carnivores will not be able to get sufficient food. Hence, this option is also incorrect
Option C is also not feasible as equal number of scavengers will not be able to degrade the large biomass of dead animals and plants.
Hence, option D is correct
Answer:tHE ANSWER IS d
Explanation:
2.Collect a 5-mL water sample at 8 am at a different location each day for 10 days.
3.Measure the amount of pesticide present in each sample using the same measurement tools.
After analyzing their data, the students conclude that pesticide runoff from farms is not causing the fish to die in the pond. Which of these statements best describes why their conclusion is not valid?
a. The amount of water collected each day was the independent variable.
b. The daily location for sample collection was not a controlled variable.
c. Pesticide measurements were the dependent variable.
d. The time of sample collection was not a controlled variable.
Answer:
D
Explanation:
The samples should not only be collected at 8am. Rather, they should be collected at different times of the day. Time is not a control variable, in this case, only the sample size is. Time of day can influence many factors that affect the pesticide levels in the samples hence the need to collect samples at different times of day too.
