Answer:
The answer is c)soil characteristics temperature and rainfall
Explanation:
Among the physical factors are the elements corresponding to the climate, such as temperature, rainfall, soil composition and water composition, altitude, latitude, etc., these factors are known as abiotic factors. Without these factors, there would be no life. If these factors are optimal for a living being, it develops fully. However, if the opposite happens, harmful effects appear in your life.
The right answer is D.
The effectiveness of BT-Corn compared to conventional insecticide treatment is very much higher:
* The plant itself produces the toxin that blocks the digestion of or target insects: the entire plant is protected where a treatment (out of neonicotinoids, very expensive and reserved to the seed treatment) allows only a protection of surface and must be renewed several times.
* The selectivity of the treatment is very superior: each variant of the BT molecule targets only a family of insects but we do not know the impact of their cumulative effects in the environment.
99% of the water is used for the "Transpiration" by the plants.
Answer:
The correct answer is- facilitated diffusion
Explanation:
In facilitated diffusion molecules(solutes) are moved from area having a high concentration of solute towards the area having low solute concentration through a semipermeable membrane with the help of specific proteins is called facilitated diffusion.
As molecules move along the concentration gradients so no energy consumption is required in facilitated diffusion. Transport proteins like channel proteins are used to transport the molecules across the cell.
The rate of transport is higher in facilitated diffusion than simple diffusion. Polar and charged molecules can be diffused by facilitated diffusion.
