Answer:
(B)Water evaporates from a lake into the air.
(C)Wind moves parts of rocks to another location.
(E)Polar bears dig big holes in hills of snow to protect their young.
Explanation:
The answer would be reproduce
1. Y-axis is type of sound being measured X-axis is the decibels/sound level for type of sound being measured
2. Whisper - 20 decibels, normal taking - 60 decibels, rock concert - 120 decibels
3. every ten decibels is ten times as loud. If a whisper is 20 decibels and normal talking is 60 decibels then normal talking is 40 times as intense as whispering
4. Rock concert, pain threshold and jet plane could be painful if exposed to them
Osmosis help plants to absorb water from soil. Diffusion is the process by which carbon dioxide from the stomata diffuses to the leaves and then to the cells.
Explanation:
- Example one - The genetic modifications in some of the plants can help in survive and adopt the osmosis in a very dry environment. They develop defense methods to handle the water loss.
- Example two - Some plants in a permanent dry environment like desert have special structures like reduced leaves, sunken stomata, and so on to conserve water and thus achieves diffusion.
- Another example for diffusion - loss of water vapour from leaves to the atmosphere. Another example for osmosis - the roots of the plants have high concentration than the surrounding soil and hence water flows into the roots.
Disadvantages of asexual reproduction include: offspring compete for food and space, extreme temperatures can wipe out entire colonies, negative mutations can destroy many offspring.
