Answer: 1. Plucking
2.Moraine
3. Kettle lake
Plucking is a process of erosion in glacier in which rocks and sediments are displaced by the glacier to other locations. These rocks and sediments gets freeze at the bottom of the glacier.
A moraine is a sediment deposited by a glacier. This may be in a form of thick layer of sediment called as ground moraine or a small ridge of deposits called as end moraine.
A kettle lake is formed when ice in large extent gets melted and this results in formation of depression which is called as kettle. The kettle is filled by melted water forming a lake or kettle lake.
Answer:
Through the process of photosynthesis, carbon dioxide is pulled from the air to produce food made from carbon for plant growth. Carbon moves from plants to animals. Through food chains, the carbon that is in plants moves to the animals that eat them. Animals that eat other animals get the carbon from their food too.
Answer and explanation:
Gram positive bacteria :
1) They retain crystal violet stain thus staining purple
2)They only produce exotoxins.
3)Peptidoglycan is thicker and multilayered
4)Techoic acids are present in their cell walls.
5)Lipopolysaccharides are absent in their cell wall.
6)No periplasmic space present
Gram negative bacteria :
1) They retain red safaranin stain thus stain pink.
2)They produce both exotoxins as well as endotoxins.
3)Peptidoglycan is thinner and single layered.
4)Techoic acids are absent in their cell walls.
5)Lipopolysaccharides are present in their cell wall.
6)Periplasmic space in present.
