Answer:
a. Gram negative
Explanation:
Lipopolysacchirides are found in the outer membrane of gram negative bacterial cell wall exposed to surface and are endotoxins that protects them from harmful chemicals. They are composed of lipids and polysaccharides. Gram negative bacteria are pathogenic due to their cell wall.
Your answers would be:
1. ---- B. A cell cannot be subdivided into smaller units that maintain the living state.
2. ---- The organism is a eukaryote because it has a nucleus.
3. ---- D. Water would flow into them because they are hypertonic to external environment.
If you want to know why:
1. The cell is the basic unit of life or in other words, its the smallest unit that makes up a living thing. It does not subdivided further if you are talking about sustaining life. Yes, it is made up of smaller units of organelles, but these organelles work together as a single unit (as a cell), to do life sustaining processes.
2. The organism is a eukaryote because of the presence of a nucleus. This is one of the main features of a eukaryote that differentiates it from a prokaryote. Prokaryotes to not have a true nucleus.
3. Water would flow into them, causing the cell to swell and eventually burst if the concentration of solutes would not even out before then. The process of osmosis is what brings the water into the cell. The cell would have a higher solute concentration than freshwater. Through osmosis, the water would then go to the area of higher concentration, which would be the cell.
Answer: Pan will melt ice faster than the plate
Explanation: Melting ice takes a lot of energy and this energy needs to come from somewhere. Normally this energy is released by cooling down the ice cube's surroundings, which is why you can cool a drink by putting ice cubes into it.
How fast the ice cube melts depends on how fast energy can be transferred from the surroundings into the cube. Materials like metals conduct heat very well, which means that because the cube is cooler than the pan, heat is moved from all over the pan into the cube, so the cube melts quickly. So why did the pan feel cold? As it's a good conductor, it also means that if you put your warm finger on the frying pan heat is conducted out of, and away from, your finger quickly. This makes the pan feel cold.
The plate on the other hand, conducts heat badly, so even though there is quite a large temperature difference between the ice cube and the plate , relatively little heat is transferred. This means that the cube will melt slowly. It also means that heat is not transferred out of your finger quickly, and so the plate feels warm.
Hope this helps :")
Answer:
Option C, ave destroyed much of the Arctic's fragile coastal ecosystem due to increased foraging.
Explanation:
Snow goose extensively involve in foraging activities in the small and concentrated areas. They spent large part of their day in foraging for instance female spends half of their day in foraging during spring and three fourth of their time before developing nest. Snow goose mainly feed on plants, underground roots and stems such as tubers, agricultural and aquatic plants. They destroy the habitat during winter foraging activities and make environment unsustainable
Hence, option C is correct
