Identify the independent variable by highlighting it red. Identify the dependent variable by highlighting it yellow. 1. If I increase the temperature of the seeds, then germination will increase,
Answer:
Independent variable: temperature ; Dependent variable: germination
Explanation:
The independent variable is what is being changed in an experiment. The dependent variable is what you are measuring in an experiment.
When the independent variable is changed (in this case, temperature), it effects the dependent variable (germination).
What conclusions can be drawn about the existence of carbon-12, carbon-13, and carbon-14? A) These are forms of carbon and they accommodate 6 neutrons and 6 electrons but each contains a difference number of protons - 6, 7, and 8 respectively. B) These are configurations of carbon and they have 6 protons and 6 neutrons but each contains a difference number of electrons - 8, 7, and 6 respectively. Eliminate C) These are isotopes of carbon and they all contain 6 protons and 6 electrons but each contains a difference number of neutrons - 6, 7, and 8 respectively. D) These are allotropes of carbon and they consist of 6 protons and 6 electrons but each contains a difference number of neutrons - 8, 7, and 6 respectively.
Answer:
C.
Explanation:
All these carbon atoms are isotopes: they have the same amount of protons (in this case, 6 because carbon always has 6 protons) and the same amount of electrons (6 because the carbons given have a neutral charge).
Therefore, the only thing we are changing is the atomic mass and the amount of neutrons present in each isotope.
In Carbon-12, there are 6 protons, 6 neutrons, and 6 electrons.
In Carbon-13, there are 6 protons, 7 neutrons, and 6 electrons.
In Carbon-14, there are 6 protons, 8 neutrons, and 6 electrons.
Answer:
These are isotopes of carbon they both contain 6protons and 6electrons but each contains a diff about of neutrons 6,7 and 8 respectively
2. Four students raced toy cars on a track. The mass and the acceleration of each car is

Which toy car had the greatest applied force?
A 1
B 2.
с 3
D4
Answer:
the answer is 4
Explanation:
i dont know how to explain it but i took the test and it was right.
The car with the greatest applied force is : ( D ) Car 4
Given that :
Force applied is calculated as : Mass * acceleration
Calculating the force applied on each carFor Toy car 1
mass = 0.19
acceleration = 0.15
Force = 0.19 * 0.15 = 0.0285 N
For Toy car 2
mass = 2.0
acceleration = 1.5
Force = 2 * 1.5 = 3 N
For Toy car 3
mass = 0.25
acceleration = 0.21
Force = 0.25 * 0.21 = 0.0525 N
For Toy car 4
mass = 2.5
acceleration = 3
Force = 2.5 * 3 = 7.5 N
From the answers above the car with the greatest applied force is car 4 with a force of 7.5 N
Hence we can conclude that The car with the greatest applied force is : ( D ) Car 4

Which of the following is an example of a detritus food chain?
A. Graas, Insects, Snakes.
B. Plankton, Large fish, small fish.
C. Organic matter, Bacteria, Molluscs.
D. All of the above.
Explanation:
Detritus food chain is the type of food chain that starts with dead organic materials. The dead organic substances are decomposed by microorganisms. The organisms that feed on dead organic matter or detritus, are known as detritivores or decomposers. These detritivores are later eaten by predators.

An adult panda bear must eat at least 30 pounds of bamboo in a day. There are 12 adult pandas living in part of a
bamboo forest.
How many pounds of bamboo, at minimum, must be available each day in order to support the population of
pandas?
12
30
348
360
Answer: (D) 360
Explanation:
An adult panda bear must eat at least 30 pounds of bamboo in a day. There are 12 adult pandas living in part of a bamboo forest 360 pounds must available each day.
Why does panda only eat bamboo?Panda comes under the specialist because its eats only bamboo because it's present abundantly and Thus they don't have to fight with other animals to get it.
Bamboo is rich in fibre but has less nutrients, so pandas have to eat 20 to 40 pounds of the elements every day just to get by.
Thus, option "D" is correct, 360.

A researcher observes the enzymatic polymerization of an organic molecule in a cell. Which enzyme is
MOST likely responsible for catalyzing the reaction?
A. a protein
O B. a nucleic acid
O C. a lipid
D. a carbohydrate
Answer:
A. a protein
Explanation:
Proteins function as enzymes in most of the catalyzing reactions, that increases the rate of reaction within cell.
Proteins are consist of multiple numbers of amino acids and the twisting and folding amino acids provide a unique identity to enzymes. Not all the proteins are enzymes but all the enzymes are proteins.
For example: Trypsin, Pepsin, and Lipases.
Hence, the correct option is "A. a protein".
