In order for a survey to accurately generalize the entire population, the survey MUST select participants in a RANDOM mode, and sampled individuals must have an EQUAL LIKELIHOOD of being chosen.
Random sampling refers to the sampling methodology by which each item or element of the target population exhibits the same probability of being included in the sample.
Random sampling represents the most reliable methodology of probability sampling.
Because samples are selected in a random mode, any research using a random sampling approach has high internal and external validity.

a ball is thrown straight downward with a speed of 0.80 meters per second. what is the speed of the ball 0.60 seconds after it is released? [ignore air resistance.]
The speed of the ball 0.60 seconds after it is released is 6.8 m/s.
Newton's law of motion is given by:
v = u + gt
where v is the final velocity, u is the initial velocity, g is the acceleration due to gravity and t is the time.
Given that:
u = 0.8 m/s, g = 10 m/s², t = 0.6s. Hence:
v = 0.8 + 10(0.6)
v = 6.8 m/s
Therefore the speed of the ball 0.60 seconds after it is released is 6.8 m/s.

a small amount of sodium hydroxide is added to water. when the chemical reaction reaches equilibrium, the ph is 12. which statement and conclusion about sodium hydroxide is correct?
The correct statement and conclusion about sodium hydroxide (NaOH) is: The negative log of the concentration of [tex]OH^-[/tex] ions is 12, so Sodium hydroxide is a strong base.
In Chemistry, pH literally means the power of hydrogen ions and it can be defined as a measure of the molar concentration of hydrogen ions in a particular solution, thereby, specifying the following;
The acidity of a chemical solution.The neutrality of a chemical solution.The basicity (alkanility) of a chemical solution.On a related note, a pH scale is a scale that is used to measure the concentration of hydrogen ions in both acidic and basic (alkaline) solutions.
Generally, a pH scale is calibrated with a standard measurement that ranges from 0 to 14.
On a pH scale, a solution with a pH of 7 is neutral, a solution with a pH below 7 is acidic and a solution is considered to be basic (alkaline) when its pH is above 7.
In this experiment, a small amount of sodium hydroxide is added to water, to give a pH of 12 when the chemical reaction reaches equilibrium.
Hence, the negative log of the concentration of [tex]OH^-[/tex] ions is 12, so Sodium hydroxide is a strong base.

Answer:
Nosotros las comemos.
Explanation:
Nosotros las comemos is the sentence using a direct object pronoun. Hence, option C is correct.
What is direct object pronoun?For instance, you would say I while referring to oneself as the sentence's subject, but me when referring to yourself as the sentence's object.
Pronouns, clauses, phrases, and nouns can all be used as direct objects. Finding the direct object, if there is one, is simple if you can recognize the subject and the verb in a statement.
The thing that the verb is acting on is known as a direct object. The word "vehicle" is a direct object in the sentence "He sold his car," for instance. As in "The man gave his wife a necklace," the indirect object is the person who receives the direct object. The direct object is "necklace," and the indirect object is "wife."
Thus, option C is correct.

what would be the outcome of the processes shown above if the mrna never moved outside of the nucleus?
Answer:See below
Explanation:
The process of protein synthesis initiates with the transcription process in the nucleus and continues with the translation process in the cytoplasm. If the mRNA never left the nucleus, the translation would not be possible.
-------------------------------------
The protein synthesis process involves transcription and translation.
Transcription:
Transcription is the copying process of the DNA section for the desired protein occurs.
It happens in the nucleus, where the template DNI strand is read in direction 3´→ 5´ to build the mRNA molecule in direction 5´→ 3´.
Once the transcription is over, the new mRNA molecule leaves the nucleus and goes to the cytoplasm.
Translation:
Translation occurs in the cytoplasm when mRNA meets a ribosome.
rRNA and tRNA read mRNA in the direction 5´→ 3´ to build the protein.
While the ribosome reads mRNA strain from its 5´ extreme to 3´, tRNA adds the correct amino acids to build the polypeptide.
Protein growth initiates in the AUG start codon -Metionin-, and ends when reaching either of the stop codons UAA, UAG, UGA.
If the mRNA does not move outside of the nucleus, the translation process is not possible. Only transcription would occur, but no translation. Protein synthesis could not be accomplished.

generally reduces the number of hurricanes formed in the atlantic ocean results in a more active tornado season can lead to crop damage and landslides in california
Based on meteorological information El Nino generally reduces the number of hurricanes formed in the Atlantic ocean.
This is because the impact of El Nino quells the Atlantic hurricane effect. This is done by raising the quantity of sinking motion and improving atmospheric resilience.On the other hand, La Nina results in a more active tornado season.
This is because the La Nina effect pushes the jet stream to move towards the north, and subsequently, this effect reduces around the Pacific side.Excessive rainfall can lead to crop damage and landslides in California.
This is because continuous rainfall at a certain level in California leads to erosion which can damage crops. Subsequently, continuous rainfall of about two weeks can turn erosion into landslides in California, particularly the southern side.Hence, in this case, it is considered that different climatic conditions affect the physical environment of humans.
