Grey seals breed in habitats where disturbance is kept to a minimal, like rocky shores, ice flows and islands. They feed on cold open waters. When pups are given birth in early winter or late autumn, their skins are white with yellowish tint. They are relatively helpless and rely on their mother's milk for the first few weeks after birth. They deposit a thick layer of blubber that will protect and allow them to adapt to the cold to sustain them when they will hunt for themselves.
I found this in a website, “A mutation is a change in DNA, the hereditary material of life. ... So a change in an organism's DNA can cause changes in all aspects of its life. Mutations are essential to evolution; they are the raw material of genetic variation. Without mutation, evolution could not occur.”

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.

Answer:
Lichens are not parasitic when they grow on trees, they just use the tree bark as a home. They enrich the soil by trapping water, dust and silt. When lichens die they contribute organic matter to the soil, improving the soil so that other plants can grow there.
