A polar bear has thick, white fur that camouflages it when it sits on snow. Which type of adaptation is this modification?
A. structural
B.natural
C.functional
D.behavioral
Which on is it?
Answer:B Natural
Explanation:Camouflage is a adaptation which animals use to blend in with their surroundings in order to protect themselves from the predators and hunters. This also gives them a better chance of survival and easy mode of hunting for food.
For example: white fox hides in the snow from the predators
Camouflage is a clear example of Physical or Structural adaptations.
-Body shape, color and body patterns are the adaptations that assists both predators and prey to camouflage
-As in the example mentioned, the polar bear with its white fur hides in the snow and waits for the right time to attack its prey without being seen

Some jellyfish are transparent, how will this affect their ability to survive?
So predators cannot see it as well
Explanation:
It will affect their ability to survive because...since Jellyfish bodies are transparent, that means they are less visible to predators or threats. Which will affect their way to survive because since they are less visible to predators, it gives them a better chance for survival since their predators can't see them very well. It also gives them a better chance for survival because hunters won't be able to see them well enough to catch them because they blend in with the water, which is called transparent.

Which statement explains what happens as magma rises inside a volcano?
Gases will contract in the chamber.
The pressure of the gas will disappear.
The magmatic pressure decreases.
Magma moves to other chambers.
Answer: the answer is C which is “the magmatic pressure decreases“
The magma rises and collects in chambers within the crust and as magma fills the chamber, pressure grows. If the pressure gets high enough the magma can break through the crust and spew out in a volcanic eruption., but If the pressure is low, do not break the crust. Thus the correct option is C.
What is molten magma?Magma is a molten and semi-molten rock mixture present under the surface of the Earth.
This mixture is usually made up of four parts such as a hot liquid base, called the melt, minerals crystallized by the melt, solid rocks incorporated into the melt from the surrounding confines, and dissolved gases.

Respiration taking place in presence and absence of oxygen has different end products. Aerobic respiration has the end products as carbon dioxide and water, alcohol is the end product of anaerobic respiration.
What is respiration ?It is the process in which the complex substituents are broken into simpler products in the presence of oxygen and absence of oxygen in order to produce energy.
In the aerobic respiration processes like glycolysis takes place where the glucose breaks down into 4 molecules of ATP with the consumption of 2 ATP molecules. 1 glyceraldehyde molecule is produced from the glucose that is 2 glyceraldehyde molecules are produced. Total of 4 ATP are produced.
Alcoholic fermentation is the anaerobic respiration that says the anaerobic respiration where the glucose is broken down into alcohol and water. In the anaerobic respiration, excess of alcohol gets broken down into lactate.

What are some things water will adhere to? and What are some things water will not adhere to?
Answer:
1. Water has an amazing ability to adhere (stick) to itself and to other substances. Hydrogen bonds form when hydrogen atoms covalently bonded to nitrogen (N), oxygen (O), or fluorine (F) in the form of covalent compounds such as ammonia (NH3), water (H2O) and hydrogen fluoride gas (HF).
2. In the case of water, hydrogen bonds form between neighboring hydrogen and oxygen atoms of adjacent water molecules. The attraction between individual water molecules creates a bond known as a hydrogen bond.
