The species that has the same predators as species c would benefit the most
Most, maybe all, bacteria have their genome DNA tethered to their cell membranes, so it is in the cytoplasm but its not really floating around. Plasmids in bacteria however are free floating. This is why it's so easy to isolate plasmids from bacteria with centrifugation after lysing.

Answer: When wilted plants are given water, it enters the cell generating turgor and giving a firmer appearance, and this water is stored in the vacuoles.
Explanation:
Turgor is a phenomenon in plant cells in which the cell expands due to the pressure exerted by the fluids and also by the cell content on the walls. It is related to osmosis, since the external pressure is usually very high and this internal pressure dilates the cell as much as the elasticity of the membranes allows. <u>Then, the cells swell by absorbing water, tensing the membranes because of the pressure against them.</u> When the fluid exerts outward pressure on the cell wall it is called turgor pressure. Whereas, the inward pressure exerted on the cell contents by the stretched cell wall is called wall pressure. Generally, both pressures, turgor pressure and wall pressure, are counterbalanced and balanced.
So, this pressure of turgor facilitates the elongation of the cells in the plant, and also, the cells use this phenomenon to regulate the transpiration through the opening and closing of the stomach.
Thereby, the turgor of a living cell is influenced by three primary factors:
- An adequate supply of water.
- The formation of osmotically substances.
- A semi-permeable membrane.
Vacuoles are organelles bounded by a single membrane and present in plant and fungal cells, and where water is stored. Plant cells control their turgor pressure through the movement of water into or out of vacuoles. When wilted plants are given water, it enters the cell generating turgor and giving a firmer appearance, and this water is stored in the vacuoles.
<span>The outermost covering of a plant cell is called cell wall. It is made up of cellulose. It surrounds the cell membrane. Its function is to protect the cell, provide mechanical support and maintain the pressure inside the cell. Fluid collects in the vacuole and pushes out against the cell wall. This turgid pressure is responsible for the crispiness of fresh vegetables and flowers.</span><span />
