<u>Answer;</u>
Wind turbines can interfere with migrating birds.
Wind is always reliable.
Wind turbines are noisy and unattractive.
<h3><u>Explanation;</u></h3>
- A wind turbine creates reliable, cost-effective, pollution free energy. It is affordable, clean and sustainable.
- Despite having relatively little impact on the environment compared to conventional power plants, concern exists over the noise produced by the wind turbine blades and visual impacts to the landscape.
- Wind turbines do kill some birds and thus interfere with the migrating birds, together with bats, they kill worrying number of bats. Turbine blades could also damage local wildlife.

It all depends on the species, some lose all of their leaves for part of the year while others lose their leaves before the next growing season, retaining some during winter or dry periods.
Answer:
Permeable membranes allow anything to pass through.
Impermeable membranes have a poor permeable rate or nothing can pass through.
Semipermeable membranes select or allow only certain substances to pass through.
Explanation:
Permeable Membranes:
- Window screen - can pass water and air through 100%
- Mesh - can pass water and air through 100%
Impermeable Membranes:
- Clay - permeability rate is extremely low, and water cannot pass through
- Ziplock bag - nothing can come in or out
Semipermeable Membranes:
- Plant and Animal cell membranes (lipid bilayer) - only certain substances can pass through, like soluble vitamins
- Cell Organelle Membranes - only certain substances can pass through the mitochondria, for example
These bacillus thuringensis species of bacteria secrete protein crystals that
are toxic to most insects hence used in agriculture to kill pests that attack
the crops. This is also the reason the genes responsible for this protein
crystal is incorporated in crops (transgenic crops) to make them resistant to
pests.
B. subtilis is important in the nutrient cycle and availing nutrient to plants hence promote plant growth
Both species are able to survive harsh conditions and remain dormant for long periods of time as spores hence their suitability in application in agriculture
