Answer: Microwaves and X-rays have different wavelengths and frequencies. Microwaves fall between infrared radiation and above radar radiation. X-rays fall above ultraviolet radiation and below gamma ray radiation. Visible light falls between infrared and through ultraviolet.

Answer:
Channel proteins and Carrier proteins
Explanation:
These are type of membrane proteins that transcend the entire length of phosphoslipid bi- layer in the plasma membrane.They facilitate the movement of ions and molecules across the walls of the plasma membranes.
Generally, substances like glucose, amino acids, are too large to pass through the phopholipid bilayers. Likewise ions of potassium, sodium calcium, because of their polarities can not pass through either. They are ferried across the phospholipid by group of protein structures called channel proteins. Some are also transported across by carrier proteins. The process by which these protein structures aided the diffusion of substances across the phospholipid bilayer is called Facilitated diffusion.
Channel proteins are pores, that are filled with water molecules with the entrance well gated. That is the entrance is controlled by part in the inner structure of the protein which can open or close the pores like a gate to control the movement of ions across it. e.g Sodium channels are gated for movement of sodium ions by voltage or ligands(chemicals) during nervous transmission to elicits action potential. Like wise Potassium channels allow diffusion of potassium ions across the phospholipid bilayers. it gates are shut when sodium channels are open; this regulate ion exchange.
Their structures are well fixed in shape , specific to the substance or ions being transported;and the rate of diffusion depends on the like hood of opening of the gate or closure.
Carrier molecules also in the membranes do not have a fixed shape, and their transport direction is determined by the direction of concentration gradients. Thus they can flip on either sides of the membranes to aid diffusion across. Their movement can be both passive and active, and the rates of diffusion depends on the number of available carrier proteins in the membrane. They are also specific to the ions they transport.And are not gated,
Therefore these two membrane integral proteins facilitate movements of substances across the phospholipild bilayers
Answer:
1.To prepare compost, either a plastic or a concrete tank can be used. The size of the tank depends upon the availability of raw materials.
Collect the biomass and place it under the sun for about 8-12 days. Now chop it to the required size using the cutter.Prepare a cow dung slurry and sprinkle it on the heap for quick decomposition.Add a layer (2 – 3 inch) of soil or sand at the bottom of the tank.Now prepare fine bedding by adding partially decomposed cow dung, dried leaves and other biodegradable wastes collected from fields and kitchen. Distribute them evenly on the sand layer.Continue adding both the chopped bio-waste and partially decomposed cow dung layer-wise into the tank up to a depth of 0.5-1.0 ft.After adding all the bio-wastes, release the earthworm species over the mixture and cover the compost mixture with dry straw or gunny bags.Sprinkle water on a regular basis to maintain the moisture content of the compost.Cover the tank with a thatch roof to prevent the entry of ants, lizards, mouse, snakes, etc. and protect the compost from rainwater and direct sunshine.Have a frequent check to avoid the compost from overheating. Maintain proper moisture and temperature.

The peas haven't start germinating, which means no leaves. They can't undergo photosynthesis to produce oxygen. At this stage they are still undergoing respiration, which produce carbon dioxide.
