<span>Contact lens solution is sterile when it is new in the bottle, but when opened it can become contaminated in a few days depending on conditions. The inside of a personal contact lens case is often very dirty.</span>
Answer: Option A.
To catalyze chemical reactions
Explanation:
Enzymes are substances or biological catalysts that speed up and drive chemical reactions in the cells.
Without enzymes life will not exist because enzymes are present in most cells and help to perform complex tasks the cells cannot do on their own.
Enzymes perform functions in digestive system by breaking complex food in to simpler form which the body can absorb.
Enzymes help also in metabolism. Enzymes catalyse chemical reactions.
Passive transport means the cell does not have to spend energy to move gasses and fluids. the gasses or liquids go from a higher concentration to a place of lower concentration. Think about shaking a can of soda. There's a lot of pressure that builds up in the soda. When you open the soda, all of the pressure escapes to an area of lower pressure outside of the can. This is called diffusion. Osmosis is another form of passive transport. For example, in water osmosis, the water goes from a less salty solution to a more salty solution.
The correct answer is A. Diffusion and osmosis.
hope this helps =)
The correct answer is A. You need to have something that starts with grass and ends with the owl. So the vole has to be in the middle.
Answer:
A. Species that remained after the extinction were able to radiate, new adaptations arose, and these adaptations produced the diversity seen today.
Explanation:
When species went extinct they also left niches that could be occupied by "new" species; new places to live, places to be filled in the food web and different relationships to be formed. The wide availability of resources made organisms to radiate leading to a "new" diversity of shapes, sizes, and lifestyles.
B. Species that have gone extinct were able to re-evolve from the ancestors that survived the extinction. If you are extinct you are gone forever.
C. Species that remained after the extinction were unable to speciate. Therefore, the number of species on Earth today is lower than the number of species present just before either extinction. The fossil record proves that species have changed over time and the diversity has changed over the history of Earth.
D. Species that remained after the extinction represented all of the lineages that were present before the extinction event. Therefore, extinction did not change the diversity of lineages. Again, the fossil record is evidence that lineages have changed over the history of the Earth.
