D. Reaction time
Objects falling are moving quickly, and being able to react immediately is the most useful skill in this situation. Being agile or having good balance isn't helpful if the object has reached the ground before you moved.
Answer:
Three different ways in which antiretroviral drugs can prevent the formation of new viruses are:
- Inhibiting the reverse transcriptase enzyme in both nucleoside analogues and non-nucleoside analogues.
- Enzymatic inhibition of integrase enzymes.
- Inhibiting entry by antagonizing CCR5 co-receptors.
Explanation:
Antiretroviral drugs are those used for the treatment of human immunodeficiency virus (HIV) infection, making the effect of the virus on the host cell is less and preventing the development of AIDS.
This type of drug has been classified, according to their mechanism of action, being grouped into several families of drugs. Three different ways by which antiretroviral drugs can prevent the formation of virus are:
- <em><u>Inhibition of reverse transcriptase enzyme</u></em><em>: this enzyme is a DNA polymerase capable of forming single strand viral RNA by a process that is reverse to normal DNA to RNA transcription. Its inhibition prevents the formation of viral particles in the host cell. They are divided into nucleoside analogs and non-nucleoside analogs.</em>
- <em><u>Enzymatic Inhibition of Integrase enzymes</u></em><em>: this type of enzyme is contained in the virus, and is capable of causing a retrotranscribed DNA to integrate into the host cell's DNA so that viral replication occurs. Its inhibition prevents the replication process.</em>
- <em><u>Entry inhibitors or antagonists CCR5 co-receptors</u></em><em>: CCr5 is a membrane protein, found on the surface of CD4 T lymphocytes, which facilitates the entry of the virus into the cell. The drug acts as a competitive inhibitor of the viral particle, preventing the entry and infection of the host cell.</em>
The most effective treatments against HIV infection involve the use of two or more types of antiretroviral drugs.
Answer:
Autism Spectrum Disorder
Explanation:
In psychology and according to the DSM-V, the Autism Spectrum Disorder is a psychopathology disorder which has the following criteria for diagnosis:
- Deficits in social communication and interactions with other people: reduced sharing of interest of conversations with other people, s<u>peaking only a few words, difficulties to make eye contact.</u>
- Restricted, repetitive patterns of behavior, interests, or activities: echolalia, repetitive behaviors, inflexible adherence to routines.
This symptoms are not explained by another illness or mental condition.
In this example, Will rarely makes eye contact with others, only speaks a few words and engages in repetitive hand flapping behavior. We can see that <u>he is showing deficits in social communication as well as repetitive patterns of behavior. </u>Therefore, he would probably be diagnosed with Autism Spectrum Disorder
Explanation:
Her nervous system doesn't allow her a quick response to pain however she can a will feel the pain in the long term.
According to the research, the correct option is Physical health. It is the component of health that involves avoiding drugs and alcohol.
<h3>What is health?</h3>
It is the degree of efficiency of the metabolism and the functions of a living being at a micro (cellular) and macro (social) scale that enjoys well-being both physically and mentally and socially.
In this sense, to maintain physical health in optimal conditions, it is recommended to exercise regularly, nutritious and balanced diets, avoiding the intake of alcohol and other drugs.
Therefore, we can conclude that according to the research, the correct option is Physical health. It is the component of health that involves avoiding drugs and alcohol.
