Question

evaluate the following statements, and select those that apply to sars - cov - 2, the enveloped virus responsible for covid - 19.
sars - cov - 2 represents one of the least resistant microbial forms.
autoclaves are necessary to destroy sars - cov - 2 viral particles from objects.
detergents and alcohols can be effectively used against this virus.
effective disinfectant, but not antiseptic, products exist for killing this virus.
sars - cov - 2 represents one of the most resistant microbial forms.
it is easier to control sars - cov - 2 than rotavirus, a naked virus.

Explanation:

• SARS - CoV - 2 is an enveloped virus. Enveloped viruses are generally less resistant than non - enveloped (naked) viruses. So, "SARS - CoV - 2 represents one of the least resistant microbial forms" is correct.
• Rotavirus is a naked virus. Enveloped viruses (like SARS - CoV - 2) are easier to control than naked viruses. So, "It is easier to control SARS - CoV - 2 than rotavirus, a naked virus" is correct.
• Enveloped viruses have lipid envelopes. Detergents can disrupt lipid envelopes, and alcohols can also act on enveloped viruses. So, "Detergents and alcohols can be effectively used against this virus" is correct.
• Autoclaves are not necessary for SARS - CoV - 2. Many common disinfectants can work. So, "Autoclaves are necessary to destroy SARS - CoV - 2 viral particles from objects" is incorrect.
• There are antiseptic products (e.g., some alcohol - based hand sanitizers) that can kill SARS - CoV - 2. So, "Effective disinfectant, but not antiseptic, products exist for killing this virus" is incorrect.
• As an enveloped virus, it is not one of the most resistant microbial forms. So, "SARS - CoV - 2 represents one of the most resistant microbial forms" is incorrect.

Answer:

• SARS - CoV - 2 represents one of the least resistant microbial forms.
• Detergents and alcohols can be effectively used against this virus.
• It is easier to control SARS - CoV - 2 than rotavirus, a naked virus.
