two Barr bodies
A Barr body is the inactivated X chromosome when in a case like this, there is more than one X chromosome for only one place.

The risks of indoor cooking with biofuels and poor ventilation can be reduced through: better ventilation.
<h3>What is chemical pollution?</h3>
Chemical pollution can be defined as the contamination of an environment or waterway, especially through an emission of poisonous, hazardous, and toxic chemical compounds (substances) by humans and various industries.
According to the Environmental Protection Agency (EPA), chemical pollution is a change to waterways and the atmosphere which are mainly caused as a result of human activity.
In this scenario, we can reasonably infer and logically deduce that the risks of indoor cooking with biofuels and poor ventilation can be reduced through better ventilation in the cooking area, so as to efficiently and effectively diffuse the gases.
