Which of these experimental designs could lead to bias?A) Two mice are given the choice between Swiss and American cheese.
B) Phil and Bart race down the street to determine who is the fastest.
Eliminate
C) A car company pays participants to test drive and evaluate their new auto.
D) A private company uses a random taste test of three different, unidentified soft drinks.

Answers

Answer 1

Answer: C is biased because the people were paid to evaluate the car. They are more likely to say better things about it than if they weren't paid.

Answer 2

Answer: I believe it is B. The meaning of bias is prejudice in favor or against someone or a group compared to another in an unfair way. Many can have a one sided opinion about something such as who is going to win the race. However, choosing different cheese is more of an opinion showing which they prefer more than being bias.

The cell theory states that all new cells come from other cells. How do unicellular organisms reproduce? How is it different from how multi-cellular organisms increase?

Answers

the cell theory states that all new cells come from other living cells, and it's true for both multicellular as well as unicellular organisms.unicellular organisms reproduce through asexual reproduction,There are different types of reproduction like binary fission, vegetative, budding, fragmentation etc reproduction in unicellular organisms, through that they directly divide into new similar cells.

whiltin multicellular organisms, reproduction takes place through sexual reproduction, where male and female gametes are formed in separate reproductive organs and get transferred to form an embryo.

so in nut cell in unicellular organisms there is no specific organs,that is responsible for reproduction, while in multicellular there coplex reproductive system

A 5.00 L sample of air at 0 C is warmed to 100.0 C. What is the new volume of the air? First, identify V1.

Answers

Answer : The new volume of the air is, 6.83 L

Explanation :

Charles' Law : It states that volume of the gas is directly proportional to the temperature of the gas at constant pressure.

Mathematically,

$(V_1)/(T_1)=(V_2)/(T_2)$

where,

$V_1\text{ and }T_1$ are the initial volume and temperature of the gas.

$V_2\text{ and }T_2$ are the final volume and temperature of the gas.

We are given:

$V_1=5.00L\nT_1=0^oC=(0+273)K=273K\nV_2=?\nT_2=100^oC=(100+273)K=373K$

Putting values in above equation, we get:

$(5.00L)/(273K)=(V_2)/(373K)\n\nV_2=6.83L$

Therefore, the new volume of the air is, 6.83 L

Why is the structure of molecule important to its function?

Answers

Answer:

In materials of molecular structure, the nature of intermolecular and intramolecular bonds has a decisive influence on their characteristics and properties. Characteristics such as melting and boiling points, mechanical strength and hardness depend on the type of such bonds.

A Molecule's Biological Function is Related to its Shape. Each molecule has a characteristic size and shape that determines its function in the living cell. The shapes of molecules are determined by the positions of the atoms' orbitals. When an atom forms covalent bonds, the orbitals in its valence shell are rearranged that’s your answer

HURRY!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!One object has a speed of 1 mph and another object has a speed of 3 mph. If the masses are the same, which of the following is true about their kinetic energy?

Question 7 options:

Their speeds are the same.

the object with the greater speed has greater kinetic energy

the object greater speed has the lower kinetic energy

the object with the smaller mass has the greater kinetic energy

Answers

Answer: Option (B) is the correct answer.

Explanation:

Kinetic energy is the energy due to the motion of an object.

Mathematically, K.E = $(1)/(2)mv^(2)$

where m = mass

v = velocity

Therefore, an object whose velocity is more will have more kinetic energy.

Thus, we can conclude that out of the given options, the object with the greater speed has greater kinetic energy is true about their kinetic energy.

The object with the greater speed has greater kinetic energy
