Answer: Cohesion
Explanation:
The cohesive attraction or cohesive forces is the action or property of like molecules which stick together.
It can be intrinsic forces that can be caused by the structure and shape of water. This allows the water molecules to stick to each other.
Due to this phenomenon of water it has a spherical shape and it flows in a liner motion.
Hence, the force that is present between two water molecules is cohesion.
Answer: B) Jupiter and the sun have a similar composition.
Explanation:The only significant difference between the sun and Jupiter is in the sizes i.e jupiter is smaller compared to the size of the sun.
However their similarities is in their composition i.e what they are made up (helium and hydrogen).
The core of Jupiter is made up of liquid metallic hydrogen and the sun's core or center is also made up 34% mass plasma of hydrogen.
So option B (Jupiter and the sun have a similar composition) best describes the relationship between Jupiter and the sun.
At the low temperature, a particular enzyme catalyses a reaction best explains temperature affects the function of this enzyme.
Explanation:
Enzymes are those catalysts which is generally proteins through some RNA molecules as enzymes too. The activation energy of reaction of Enzymes lower is required amount of energy which is needed for occurring the reaction.
Temperature, pH and concentration affect the Enzyme activity. The raising of temperature generally speeds up the reaction. Due to high temperature enzyme to lose its shape and stop working. The part of enzyme where substrate bind is called the active site.
Relapsing, recovering requires time, motivation and support. managing withdrawal symptoms.
