Which variable responds to the changes of the independent variable? A-independent B-causation C-dependent D-Controlled
Answer:
The dependent variable
Explanation:
The independent variable is always changed by the scientist, and what happens then is known as the dependent variable because it depends on the indépendant variable!
Terrence buys a new car for $20,000. The value of the car depreciates by 15% each year. If f(x) represents the value of the car after x years, which function represents the car’s value?
f(x) = 20,000(0.85)x
f(x) = 20,000(0.15)x
f(x) = 20,000(1.15)x
f(x) = 20,000(1.85)x

Which is the best hypothesis for the scientific question "How does light intensity affect the rate of photosynthesis?"
O Light intensity, CO2 concentration, and temperature are factors that determine the rate of photosynthesis.
O Light intensity has no effect on the rate of photosynthesis,
• If the distance between the source of light and the plant is increased, the rate of photosynthesis will decrease.
Light intensity has an impact on the rate of photosynthesis.
Answer: • If the distance between the source of light and the plant is increased, the rate of photosynthesis will decrease.
Explanation:
its good to think about the hypothesis as an if then statement. Example: If the independent variable(light intensity) is changed than the dependent variable(rate of photosynthesis) with be effected in this way.

An investigation was designed to determine how freshwater fish maintain homeostasis within their environment. It was observed that the concentration of substances inside the fish cells was much higher than the concentration of substances in ponds, lakes, and streams and that freshwater fish have a constant flow of water from the environment into their cells.
Based on these observations, in what type of environment must these fish live?
A
hypertonic
B
hypotonic
C
isotonic
D
osmotic
The freshwater fish must live in a hypotonic environment to maintain homeostasis
WHAT IS OSMOSIS:
Osmosis is the movement of water from region of higher concentration of water or low concentration of solute to a lower concentration of water or higher concentration of solute. In terms of tonicity, a solution with high concentration of solute is called whileHYPERTONIC a solution with low concentration of solute is called HYPOTONIC. If the freshwater fish regulates water loss by having a constant flow of water from the environment into their cells, then the FISHES must live in an environment that has a higher concentration concentration of water than their cells i.e. a HYPOTONIC SOLUTION.Hence, the freshwater fish must live in a hypotonic environment to maintain homeostasis

Ecosystem: includes all living things functioning together with the physical factors of their environmentBiome: is a large geographical area classified by its climate and the plant and animal life within itHabitat: includes all living things and the areas in which they live. What is an Ecosystem?An ecosystem may be defined as a place or an area where members of different species live together and interact with one another for the purpose of food, shelter, and space.
The Ecosystem comprises all biotic and abiotic factors of any geographical location. The Biosphere only includes the living forms where they efficiently live and play their roles. Habitat is the area where a particular type of organism is best adapted due to natural selection.
Therefore, the matching of each term with respect to its description is appropriately described above.

How are acids and protons related? (1 point)
O An acid can donate protons to a base when they react.
Acids are substances that contain more protons than bases.
An acid can accept a proton from a base when they react.
Acids are substances that contain fewer protons than bases.
Answer:yes
Explanation:
An acid is a substance that donates protons (in the Brønsted-Lowry definition) or accepts a pair of valence electrons to form a bond (in the Lewis definition). A base is a substance that can accept protons or donate a pair of valence electrons to form a bond. Bases can be thought of as the chemical opposite of acids.
Acids and protons are related in the sense that "acid can donate protons to a base when they react".
WHAT IS AN ACID?
Acids, according to Bronsted-Lowry definition, are substances/compounds that can donate hydrogen ions (protons). An acid donates protons (H+) to a base when they react in a neutralization reaction. The donor acid becomes a conjugate base while the recipient base becomes a conjugate acid. For example;HCl + NaOH → NaCl + H2O
In this reaction, HCl acid donates a proton (H+) to hydroxide ion (OH-) to form water (H2O).Therefore, acids and protons are related in the sense that "acid can donate protons to a base when they react.
