Unlike a scientific theory, a scientific hypothesis describes an observed pattern in nature without attempting to explain it true or false

Answers

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.

Name two cell structures found in plant cells but not in animal cells, and describe their functions.

Answers

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:

In a balanced ecosystem, the number of deer would be:a) greater than the number of producers
b) less than the number of carnivores
c) equal to the number of scavengers
d) none of the above

Answers

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:

Two students completed an experiment to determine if pesticide use at local farms was causing fish kills in a local pond. The steps of the experiment are listed below. 1.Select different locations to collect water samples in the pond.
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.

Answers

Answer:

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.
