In an experiment I have two groups of flowers, A and B. As a curious scientist I wanted to test the effects of fertilizer on plant growth. Group A was not given any fertilizer, while Group B was given fertilizer. I left all other conditions the same within each group such as amount of water, type of flower, and amount of sunlight. After three weeks of running this experiment I measured the height of each plant. My conclusion was that Group B flowers were taller than Group A flowers. After reading this scenario what is the independent variable?
Answer:
Independent variable: FERTILIZER
Explanation:
The independent variable in an experiment is the variable that is changed or manipulated by the experimenter in order to bring about a measurable response.
In this experiment, the effects of fertilizer on plant growth is tested. Two groups: Group A and B were used. Group A was not given any fertilizer, while Group B was given fertilizer. This portrays that the experimenter is manipulating the FERTILIZER. Hence, the FERTILIZER is the independent variable.

Scientists discovered similar fossils in rock masses on continents located both sides of the Atlantic Ocean.How does this discovery provide evidence supporting the theory plate of tectonics?
Explanation:
Because these fossils would have had no way to get across the ocean, especially for large terrestrial animals. The continents used to be in different locations, allowing some animals to cross. These animals then died on different continents as they shifted, thereby proving that the continents used to be much closer than they are now.

What is cancer?Cancer is a medical condition in which cells in one portion of the body expand and multiply inconsolably.
Cancerous cells have the ability to invade and destroy healthy tissue, including organs. Cancer can start in one part of the body and spread to other parts. This is referred to as metastasis.
Cancer is caused by changes in genes, which are the basic physical units of inheritance. Genes are organized in chromosomes, which are long strands of tightly packed DNA.
Cancer is a genetic disease, which means that it is caused by changes in genes that regulate how our cells function, particularly how they grow and divide mitotically.
Thus, the correct options are b and c respectively.

A) All organisms have the ability to take in energy and use it.
B) All organisms have the ability to respond to stimuli from the environment.
C) All organisms have the ability to reproduce.
D) All organisms have the ability to maintain a constant internal temperature.
Answer: D
Explanation: Because organisms such as snakes are unable to do this, because they are cold-blooded
The FALSE statement is that all organisms have the ability to maintain a constant internal temperature (Option D).
Organisms are able to respond to different stimuli such as light, heat, mechanical contact, etc.Organisms use energy to carry out their metabolic functions (e.g., growth, differentiation, reproduction, etc)Poikilotherms animals, also known as cold-blooded animals, are unable to maintain a constant body temperature independently of the environmental conditions.Poikilotherm animals include amphibians, reptiles, fish, insects, and worms.In conclusion, the FALSE statement is that all organisms have the ability to maintain a constant internal temperature (Option D is correct).
