Question

Although plant viruses cannot infect humans, what are some of the ways in which they affect humans?

a) By causing respiratory infections.
b) By contaminating water sources.
c) By reducing crop yields and food supplies.
d) By directly infecting the human immune system.

Answer 1

Plant viruses do not directly infect humans but can affect them by reducing crop yields and food supplies, damaging plants used for landscaping, and causing economic losses.

Step-by-step explanation:

Although plant viruses cannot directly infect humans, they can affect humans in several ways.

1. Plant viruses can reduce crop yields and food supplies, leading to economic losses and potential food shortages.
2. Some viruses that infect plants used for landscaping can damage these plants, affecting their aesthetic value.
3. It is important to note that plant viruses do not cause human diseases such as respiratory infections or directly infect the human immune system.
4. Humans, or modern humans (Homo sapiens or H. sapiens), are the most common and widespread species of primate. A great ape characterized by their hairlessness, bipedalism, and high intelligence, humans have large brains, enabling more advanced cognitive skills that enable them to thrive and adapt in varied environments, develop highly complex tools, and form complex social structures and civilizations.
