Cell wall is the answer to your question.
Dialysis is a passive process that favors the transport of small molecules across a semipermeable membrane.
Answer:
C: Lowering activation energy
Explanation:
A catalyst speeds up a chemical reaction, without being consumed by the reaction. It increases the reaction rate by lowering the activation energy for a reaction.
A) Some members of the Euglenoids lose their photosynthetic pigment when left in Dark : TRUE
B )The loss of photosynthetic pigment in Euglenids stored in the dark is permanent : False
<h3>What are Euglenas</h3>
Euglenas are unicellular organisms belonging to the kingdom Protista, when kept in the dark for too long Euglenoids begin to lose their chlorophyll. As it loses its chlorophyll it becomes unable to produce its own food and starts consuming bacterias within its habitat.
The loss of chlorophyll in Euglenids can be regained after it is been exposed to sunlight and allowed to grow exponentially for several weeks.
Hence we can conclude that Some members of the Euglenoids lose their photosynthetic pigment when left in Dark : TRUE while The loss of photosynthetic pigment in Euglenids stored in the dark is permanent : False

Answer:
B
Explanation:
A- The lake ecosystem has no other larger fish
B- The fish shares a niche with another species
C- There are no organisms that would eat this fish
D- The fish can thrive in the temperature of the week
<em>The correct answer would be option B.</em>
One of the factors that promote invasiveness in exotic species is if<u> such species lack natural predators or competitors</u>. In other words, <u>the invasiveness of a nonnative species can be promoted when they occupy a previously unoccupied niche, resulting in a lack of competition. </u>The presence of a competitor will either results in <u>a competitive exclusion</u> that might not favor the newly introduced species or <u>resource partitioning</u> that sort of limits their growth.
Hence, in the case of the nonnative fish introduced into a lake, sharing a niche with another species can prevent it from becoming an invasive species.
