The three changes of state during which energy is absorbed are:

1. Change from solid to liquid - Melting.

2. Change from liquid to gas - Vaporization

3. Change from solid to gas - Sublimation

All these changes of state require heat energy to break the attractive forces that hold the particles of the molecules together, so that they can move into more disorderly states. For instance, when heat is applied to a solid, the solid absorbs the heat and use it to break the attractive forces that are holding the molecules of the solid together. At a particular temperature, the attractive forces will be completely overcome and the solid framework will collapse, thus leading to the melting of the solid.

Three changes of state during which energy is absorbed are : 1. solid to liquid - heat goes into the solid as it melts. 2. Liquid to gas - Heat goes into the liquid as it vaporizes. This change of state includes boiling and evaporation. 3.Solid to gas - this is sublimation. Heat goes into the solid as it sublimates. Change in phase of a material or substance always involves a change of heat whereby heat energy is either absorbed into the material or given up from the material

Which characteristic differentiates amphibians from reptiles?

Stells [14]

Option D – amphibians may use their skin for gas exchange is the characteristic feature of amphibians that differs from reptiles.

Explanation:

The amphibian skin is moist, thin and marbled and supplied by blood vessels running on its surface. The moisture present in the skin dissolves the oxygen present in its surrounding which is absorbed by the blood vessels. Special glands help the amphibians to keep the skin moist.

The very thick and tough scales present on the reptiles prevent them to absorb oxygen through their skin. Hence, they breathe and respire through their lungs.

Amphibians have three-chambered heart. They do not develop amniotic eggs. Adult amphibians although spend much time on land, they breed only in water due to the absence of amniotic sac .

QUICK QUESTIONS!! THANK YOU!! Why do we have limestone? what do iron bands mean?

andriy [413]

First question is - Why do we have limestone? Formed from this type of sediment are biological sedimentary rocks. Their biological organ is often revealed in the rock fossils. Some limestones can form by direct precipitation of calcium carbonate from marine or fresh water. (The second question is) - What do iron bands mean? The rocks are "banded" because the iron minerals deposited in alternating bands with silica and sometimes shale. The banding might have resulted from seasonal changes in organism activity steel mill. Most iron ore is used to make steel. Here a steel slab is being cut to length in a steel mill.

TRUE OR FALSE Both animal and plant cells use cellular respiration to make energy.

Radda [10]

Answer:

It's responsible for cellular respiration in both plants and animal cells. The difference is that plants also have chloroplasts that perform photosynthesis. Animals get their energy by eating food, digesting it, and turning it into the base sugars, proteins, and lipids that the cells can burn to perform cellular respiration (which makes ATP).

The two main components of plant fertilizers which affect algal growth when they are delivered to aquatic systems via runoff are

sertanlavr [38]

Nitrogen and phosphorous are the most prevalent aquatic pollution and contribute heavily to the excessive growth of algae in aquatic environments called algae blooms. The nitrogen from the fertilizers is found in molecules called nitrates which are compounds of both oxygen and nitrogen. Phosphorous helps algae to absorb carbon dioxide. So when the phosphorous levels are high the algae absorbs more carbon dioxide, which allows for faster photosynthesis and faster glucose production which leads to faster growth. Although algae need both nitrogen and phosphorous to grow, when the levels are too high the algae grows faster than the ecosystem can sustain leading to oxygen deprivation for the other aquatic organisms.
