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).

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).

Manganese dioxide and catalase are different because manganese dioxide is an inorganic catalyst. Conversely, catalase is an organic 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.

Myth: A dead organism is the same as a nonliving thing in science.

Fact: A non-living thing can be very different than a living thing.

Explanation:Evidence: Once- living things are made up different things then non-living things. While a rock is a nonliving thing, it doesn't contain the same build as living things. If we were to look at a dead once living being, we could probably conclude that it was a living thing since it contains things like cells, proteins, etc. That other thing, like dirt, wouldn't have.

Answer: First Third Fourth Choice

Explanation: Becuz when water freezes, the density becomes lower and the bonds stabilize, resulting in the molecules moving apart.

Water is an excellent conductor of heat for which animals may control temperature through transpiration and thus maintain a suitable 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.

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.

A slow and gradual type of eruption is happening with this volcano. The magma of which is very viscous so the lava slowly flows very far from the crater.

A volcanic eruption may be characterized as an introduction to the earth's crust through which lava, volcanic ash, and gases exit on the ground surface.

No, this volcano is not likely to have a massive eruption. It is a type of Shield volcano which produces low viscous magma and spreads far from the crater gradually.

Therefore, it is well described above.
