The correct answers are: cold climates, low moisture levels
Weathering is simply saying decomposition or breaking of rocks and it depends on different factors: mechanical (like temperature and pressure) or chemical (changing the composition or mineral type).
Climate affects the rock decomposition, weathering occurs fastest in hot, wet climates. Also, moisture affects weathering by speeding up chemical weathering. When it comes to rock composition, some minerals resist weathering others don’t. For example, quartz weathers slowly while rocks with feldspar, calcite, and iron, weather more quickly.
Another factors that influence weathering are surface area of the rocks (more surface are, more exposed, more weathering) and pollution which speeds up weathering.
The answer would be B as penicillin is derived from Penicillium fungi.
The work of Rachel Carson and the other ecologists has revealed the terrible consequences of the overuse of DDT. These ecologists worked at the ecosystem level of environmental interaction because they studied the depth of relationships between organisms and their environment.
An ecologist studies environmental problems and determines what causes them and how to improve the situations. In research, they gather data and analyze that for importance. Although, DDT (Dichloro Diphenyl Trichloroethane) was developed or invented as the first of the modern synthetic insecticides in 1940.
Hence, Rachel Carson and other ecologists found that overuse of DDT causes harm to the human liver and reproduction. As a result, humans face symptoms like vomiting, tremors, or shakiness. These problems were affecting the ecology and causing environmental disbalance. So those ecologists were working on the ecosystem level to solve the problem.

Answer:Cholesterol helps to restrict the passage of molecules by increasing the packing of phospholipids. Cholesterol can fit into spaces between phospholipids and prevent water-soluble molecules from diffusing across the membrane.
