A very large star of high luminosity and low surface temperature. Red giants are thought to be in a late stage of evolution when no hydrogen remains in the core to fuel nuclear fusion.
The cell wall is a rigid organelle composed of cellulose and lying just outside the cell membrane. The cell wall gives the plant cell it's box-like shape. it also protects the cell. The cell wall contains pores which allow materials to pass to and from the cell membrane.
Answer:
These, problems posed by Burmese pythons in Everglades National Park show that preventing the release of exotic animals is extremely important. Once they are established, removal becomes much, much harder.
If we let the Burmese pythons roam, they will attend to do damage to the ecosystem. Everyone needs to take control/action
The activity is genetic engineering
Acclimation is the physiological response or phenomenon which is responsible for survival of salmon in fresh water and salt water.
When a young salmon starts its sea journey it travels wide distances in search for oceans completing a leg of their journey. They travel back to home streams for spawning. This survival in different osmotic potentials and salinity is due to osmoregulation and acclimation. System of salmon detects saline change and instigates a negative feedback system to the body water concentration. Similar feedback works contrastingly when salmon is in fresh water or marine streams of water.
Hence, the physiological response occuring in salmon is acclimation.
