List one way in which manganese dioxide and catalase are different.
Manganese dioxide and catalase are different because manganese dioxide is an inorganic catalyst. Conversely, catalase is an organic enzyme.
What is an enzyme?An enzyme is an organic catalyst (i.e., a protein) that acts to speed up a chemical reaction by lowering its activation energy.
Catalase is an enzyme that catalyzes the decomposition of hydrogen peroxide (H2O2) into oxygen (O2) and water (H2O).
Manganese dioxide also catalyzes the decomposition of H2O2 to oxygen and water, but it is an inorganic compound.

what property of water allows an animal to release excess heat in hot environments
Water is an excellent conductor of heat for which animals may control temperature through transpiration and thus maintain a suitable body temperature.
How does transpiration help animals to control body temperature?The process of transpiration helps animals control body temperature by relating water which serves to conduct the heat and dissipate it into the surrounding environment to decrease the body temperature.
Therefore, with this data, we can see that transpiration helps animals control body temperature by increasing heat conductivity and thus removing the excess heat from the body.

Which structure controls the movement of tube feet?
a.skin
b.sieve plate
c.collagen
d.ampulla
Answer:
The water-vascular system, which functions in the movement of tube feet, is a characteristic feature of echinoderms, and evidence of its existence has been found in even the oldest fossil forms.
Ampulla structure controls the movement of tube feet. So, the correct option is (D).
What is Tube Feet?Tube feet are defined as the small active tubular projections present on the oral face of an echinoderm. It is present on the arms of a starfish, or sea urchin, sand dollar, and sea cucumber. Although present on brittle stars, they are more discreet, and have only a feeding function in feather stars.
Starfish belongs to the phylum Echinodermata whose body is covered with spines and move with the help of tube feet. It help the urchin to move but also used to grasp food. This is the part of the respiratory or breathing system.
The tube feet can expand or contract which is based on the volume of water i.e. hydrostatic pressure present in the system of the arm.
Thus, ampulla structure controls the movement of tube feet. So, the correct option is (D).

What happens to the carbon dioxide (CO2) levels of a plant when it does or does not have light?
Explanation:
Carbon dioxide is needed for photosynthesis, but oxygen is needed for cellular respiration. Assuming there is still oxygen then the plants will produce carbon dioxide and some of it will be reabsorbed by photosynthesis during daylight. However, ultimately there wouldn’t be enough carbon dioxide for the plants to grow and they will start to die. Some plants have evolved a C4C4 photosynthesis pathway so they only require a small amount of CO2CO2 to survive, however they do still require more than zero CO2CO2.
So basically you killed off all the plants and all the other non-microbial life died of starvation shortly afterward.
