Can you describe a frogs metamorphosis, including whether it is complete or incomplete
Explanation:
Frog undergoes a complete metamorphosis. It includes the egg, tadpole, froglet and then adult frog stages. In complete metamorphosis the hatchling does not resemble the parent and changes as it grows to be an adult.
During metamorphosis the tadpole will develop back legs first, then front legs. Around 6 weeks of life the mouth starts to widen. Sometime around 10 weeks the froglet’s, as it is now called, eyes start to bulge out and the tail begins to shrink and eventually disappear. When the lungs finish developing the froglet makes it’s way onto the land and, Ta-da! It’s a frog!
Hope this helps!

Answer:
In order:
Stalactities
Stalagmites
Swallowhole
Sinkhole
The correct match of the features are:
Stalactites: Grow toward the cave floor.
Stalagmites: Grow toward the cave ceiling.
Swallow hole: A cave that has collapsed because of gravity.
Sinkhole: Where a stream disappears into the ground.
What are Stalactites?Mineral deposits known as stalagmites and stalactites are frequently seen in caves. The pointy, downward-pointing minerals that fall from the caves' roofs give rise to the stalactites.
On the other hand, stalagmites are created when minerals that fall from the roof are deposited on the ground afterward.
Therefore, the correct options are:
Stalactites: Grow toward the cave floor.Stalagmites: Grow toward the cave ceiling.Swallow hole: A cave that has collapsed because of gravity.Sinkhole: Where a stream disappears into the ground.To learn more about Stalactites, refer to the link:

How can a material at a certain temperature have all of its molecules at the same energy?
Answer:
The average kinetic energy of the molecules is proportional to absolute temperature. At any given temperature, the molecules of all gases have the same average kinetic energy.
Explanation:
When heat is added to a substance, the molecules and atoms vibrate faster. As atoms vibrate faster, the space between atoms increases. The motion and spacing of the particles determines the state of matter of the substance. Solids, liquids and gases all expand when heat is added.

Do plants need to eat?Or do they acquire energy through a method different from animals?Write down the differences on how a tree and an ostrich acquire the energy they need for survival.
Plants acquire energy through a method known as photosynthesis which is different from animals. Plants make their food from the process called photosynthesis as they are autotrophs while animals depend on their food on plants and they are called herbivores.
What are Autotrophs?
Autotrophs are the organism that can produce its own food using light, water and carbon dioxide or some other chemicals. They are also known as primary producers.
The most familiar type of autotrophs are plant but apart from plants many different types of autotrophic organisms are there. For example, algae which live in water, phytoplankton which live in ocean and some type of bacteria.
Mostly autotrophs used the process called photosynthesis to make their own food. In this process, Autotrophs used energy from the Sun to convert water obtained from the soil and carbon dioxide obtained from the air to produce a carbohydrate called Glucose . It give energy to the plant.
Some rare autotrophs produces food through a process called Chemosynthesis . In this process, they make their own food using energy from chemical reaction combining Hydrogen Sulphide or Methane with oxygen . Organism that uses Chemosynthesis for making their food lives in extreme environment . For example, Bacteria live in active volcanoes oxidize sulphur to produce their own food.
Thus, plants acquire energy through a method known as photosynthesis which is different from animals. Plants make their food from the process called photosynthesis as they are autotrophs while animals depend on their food on plants and they are called herbivores.

It is the resulting pollution from human activity. It covers the use of fossil fuels in manufacturing, transportation, and thermoelectric power plants, as well as industrial gas emissions, mining, processing, and stone crushing.
The physical degradation or contamination of the environment caused by the release of hazardous, dangerous, or toxic chemical substances is known as pollution.
Oxides of nitrogen (NOX) and volatile organic compounds (VOC), commonly referred to as hydrocarbons, undergo chemical interactions that result in ozone. Both close to the earth and high in the atmosphere, this reaction is possible.
Therefore, the correct option is a. ozone.

Which is the MOST likely conclusion about a plant that has very small flowers that
are hard to see?
CLE
Answer: Pollen can be blown in the wind which the bees/other pollinators can follow to get to the flowers.
Explanation: Plants rely on bees and other insects to reproduce and so they have adapted, over time, to become more attractive to them. Bees are drawn to plants with open or flat tubular flowers with lots of pollen and nectar. A flower's scent can have particular appeal to bees, and its bright colors or pollen being blown in the wind may lure the bees in.
