What is the control in an experiment?
-
What is changed by the experimenter
-
What stays the same
-
What is measured
Correct Answer
A. What stays the sameExplanation
In an experiment, the control refers to the variable or condition that is kept constant or unchanged throughout the experiment. It serves as a baseline or reference point against which the effects of other variables are measured. By keeping the control constant, the experimenter can accurately determine the impact of the variable being tested.Rate this question:

What is the dependant variable of an experiment?
-
What is being measured
-
What stays the same
-
What is being changed by the experimentor
Correct Answer
A. What is being measuredExplanation
The dependent variable of an experiment is what is being measured or observed. It is the outcome or result that is expected to change as a result of the independent variable, which is the factor being manipulated or changed by the experimenter. The dependent variable is the variable that is dependent on the independent variable and is used to assess the effect or impact of the independent variable on the experiment.Rate this question:

What is an example of a static system?
-
Body system
-
Car
-
Measurement
-
Ecosystem
Correct Answer
A. MeasurementExplanation
A static system refers to a system that remains unchanged or at rest over time. Measurement can be considered as an example of a static system because once a measurement is taken, it remains constant and does not change unless it is measured again. In contrast, body systems, cars, and ecosystems are dynamic systems that undergo continuous changes and interactions. Therefore, measurement is the best example of a static system among the given options.Rate this question:

Which is a correct description of succession?
-
Pioneer species, bushes, dwarf trees, mature trees
-
Mature trees, dwarf trees, bushes, pioneer species
-
Pioneer species, mature trees, dwarf trees, bushes
Correct Answer
A. Pioneer species, bushes, dwarf trees, mature treesExplanation
Succession refers to the process of ecological change over time in a particular area. It typically begins with pioneer species, which are the first organisms to colonize a barren or disturbed area. These species are often hardy and able to tolerate harsh conditions. As the environment becomes more stable, bushes and dwarf trees start to grow, followed by the establishment of mature trees. This sequence of pioneer species, bushes, dwarf trees, and mature trees represents the stages of succession, with each stage paving the way for the next.Rate this question:

What is the job of pioneer species?
-
To kill off tall trees
-
Be the last in the community
-
Break down rock and form soil to start growth
Correct Answer
A. Break down rock and form soil to start growthExplanation
Pioneer species play a crucial role in ecological succession by breaking down rock and forming soil, which provides a foundation for the growth of other plants. They are the first organisms to colonize barren or disturbed areas and are able to thrive in harsh conditions. Through their ability to break down rocks and organic matter, pioneer species contribute to the process of soil formation, making it more suitable for other plant species to establish and grow. This process sets the stage for the development of a diverse and stable community over time.Rate this question:

Water sticking to other surfaces is?
-
Cohesion
-
Adhesion
-
Subhesion
Correct Answer
A. AdhesionExplanation
Adhesion refers to the attraction between water molecules and other surfaces. It occurs when water molecules are attracted to the molecules of a different substance, causing them to stick together. This phenomenon is responsible for water sticking to the sides of a glass or the surface of a leaf. Cohesion, on the other hand, refers to the attraction between water molecules themselves, causing them to stick together and form droplets. Subhesion is not a recognized scientific term.Rate this question:

The flower is what type of system?
-
Respriatory
-
Digestive
-
Reproductive
Correct Answer
A. ReproductiveExplanation
The flower is a reproductive system because its main function is to produce and facilitate the reproduction of plants. Flowers contain reproductive organs such as the stamen (male reproductive organ) and pistil (female reproductive organ), which are responsible for the production of pollen and ovules respectively. These organs allow for the process of pollination and fertilization, leading to the formation of seeds and the continuation of plant species.Rate this question:
-
- 9.
Which pollination creates a unique offspring?
-
Self-pollination
-
After-pollination
-
Cross-pollination
Correct Answer
A. Cross-pollinationExplanation
Cross-pollination creates a unique offspring because it involves the transfer of pollen from the male reproductive organ of one plant to the female reproductive organ of another plant. This process allows for the mixing of genetic material from different plants, resulting in offspring that have a combination of traits from both parent plants. Self-pollination and after-pollination, on the other hand, involve the transfer of pollen within the same plant or from the same plant, respectively, which does not result in as much genetic diversity.Rate this question:

What is a limiting factor in an eviroment? (needed to survive)
-
Houses, malls
-
Cars, dentist
-
Sunlight, water
-
Vegetables, bears
Correct Answer
A. Sunlight, waterExplanation
Sunlight and water are limiting factors in an environment because they are essential for the survival of organisms. Sunlight is necessary for photosynthesis, the process by which plants produce food, and it also provides warmth and energy. Water is crucial for hydration, nutrient absorption, and maintaining physiological functions. Without sufficient sunlight and water, organisms would not be able to meet their basic needs and would struggle to survive in their environment.Rate this question:

A build up of excess CO2 in the atomosphere is called?
-
Brown house gases
-
Green house gases
-
Gasoline
-
Photosyntheis extra
Correct Answer
A. Green house gasesExplanation
Greenhouse gases are gases that trap heat in the Earth's atmosphere, leading to the greenhouse effect and global warming. Excess CO2 is one of the main greenhouse gases responsible for climate change. Therefore, the correct answer is "greenhouse gases."Rate this question:

This is a model of _________ found in ____________.
-
RNA / cell wall
-
DNA / the cell's nucleus
-
A chain / a pocket
Correct Answer
A. DNA / the cell's nucleusExplanation
DNA is found in the cell's nucleus. It is a molecule that carries genetic instructions for the development, functioning, and reproduction of all living organisms. The cell's nucleus is the control center of the cell and houses the DNA. Therefore, the correct answer is DNA / the cell's nucleus.Rate this question:

What percent would be recessive?
-
100%
-
75%
-
50%
-
25%
Correct Answer
A. 50%Explanation
The correct answer is 50% because if the question is asking about the percentage of recessive traits, then it implies that the other percentage would be for dominant traits. In genetics, traits are inherited through genes, and each gene has two alleles, one dominant and one recessive. If an individual inherits one dominant allele and one recessive allele, the dominant trait will be expressed. Therefore, if the recessive trait is 50%, it means that the dominant trait would also be 50%.Rate this question:

The _________________ part of the cell makes proteins.
Correct Answer
ribosomes
ribosome
ribsome
robsome
ribsmeExplanation
Ribosomes are the correct answer for this question. Ribosomes are the cellular structures responsible for protein synthesis. They are found in all living cells and can be found either floating freely in the cytoplasm or attached to the endoplasmic reticulum. Ribosomes read the genetic information stored in the DNA and use it to assemble amino acids into proteins. Therefore, ribosomes play a crucial role in the production of proteins within the cell.Rate this question:

What keeps the Carbon Cycle at equilibrium?
-
Photosynthesis
-
Homeostasis
-
Prototype
Correct Answer
A. PhotosynthesisExplanation
Photosynthesis is the correct answer because it is the process by which plants and other organisms convert carbon dioxide into oxygen, helping to maintain balance in the carbon cycle. During photosynthesis, plants take in carbon dioxide from the atmosphere and release oxygen, which is then used by other organisms. This continuous cycle of carbon dioxide uptake and oxygen release helps to regulate the levels of carbon dioxide in the atmosphere, preventing it from accumulating and causing imbalances in the carbon cycle.Rate this question:
