Answer:
d. Researchers said the flu shot reduced the risk of developing the flu when it actually didn't.
Explanation:
A Type I Error can be defined as the error that occurs in hypothesis when a researcher rejects the opposite of his hypothesis even though the opposite of his hypothesis is correct or true. Type I Error can also be called a False positive.
In the question above an hypothesis was carried out by researchers to determine if getting a flu shot would reduce the risk of developing a flu.
The truth is " Getting a flu shot actually reduces the risk of developing a flu"
But the researcher hypothesis test result that would result in a Type I error says "Researchers said the flu shot reduced the risk of developing the flu when it actually didn't".
This result of hypothesis test of the researchers above is a rejection of truth (the truth is an opposite of the researchers hypothesis test) and it would result in a Type I Error.
Yes it is a requirement for liquids to do that
Natural selection is a specific mechanism of evolution in which the heritable traits help an organism to survive and reproduce successfully. answer B
Answer:
The lytic cycle.
Explanation:
<u>HIV is a retrovirus</u> that has a special enzyme called transcriptase reverse, which can synthesize DNA using RNA as a template. This replication system is particularly useful for the virus because the DNA synthesized from the RNA viral genome can be then integrated into the human chromosomes and stay inactive for years. This is called a lysogenic cycle and is characterized by a latency of the virus and an integration to the host DNA.
When there is a triggering event, <u>this latent virus can be excised from the human chromosome and start producing copies of itself using the host machinery.</u> <u>Then the virions are assembled and after that they lyse the host cell and release new infective units that can then infect neighboring cells. </u>This is called the lytic cycle of the virus and is the reproduction cycle that occurs when a person moves into the acquired immunodeficiency syndrome (AIDS) stage of HIV infection.
The reaction being described is; CO2 + H2O = H2CO3 This reaction will be affected if carbonic anhydrase acts as a catalyst will be; that H2CO3 (carbonic acid) will be produced faster. Carbonic anhydrase enzyme balances the pH of the blood and also enables the breathing out of carbon dioxide. The reaction above catalyzed by the enzyme takes place in the red blood cells where carbon dioxide is converted into carbonic acid, which further breaks down into bicarbonate ions and protons.
