Why is the polarity of water molecules and hydrogen bonding essential to adhesion and cohesion?
Some properties like Polarity makes water a good solvent, cohesion helps in stick water molecule to itself while adhesion helps it to stick with other surfaces. Water have surface tension due to hydrogen bonding.
What are the difference between adhesion and cohesion ?when two similar molecule come closer adhesion occur where as in cohesion two similar molecules face the force of attraction.
Adhesion is the force of attraction observed between the water molecules and xylem vessels while Cohesion is unrestrained among water molecules.
Capillary action and meniscus are the effects of adhesion while Surface tension, meniscus and capillary action are the effects of cohesion.
The major forces responsible for adhesion are electrostatic or mechanical forces while Cohesion is the result of hydrogen bonding and Van der Waals forces.
A strong adhesion can lead to spread of liquid all over the surface while cohesion forms water droplets.

____are compounds that produce H+ ions in solution.
Answer:
An acid is a substance or compound that releases hydrogen ions (H+) when in solution. In a strong acid, such as hydrochloric acid (HCl), all hydrogen ions (H+), and chloride ions (Cl-) dissociate (separate) when placed in water and these ions are no longer held together by ionic bonding.
List two ways in which bacteria are important to humans. Briefly explain these ways.
One way is that the bacteria that lives in your intestine help you digest. Ususally things in your intestine that the human body can't breaking it down along with the other food. Also meaning that that bacteria also aids in taking in nutrients.
The second way bacteria can also help you get over an illness. The bacteria in your immune system fight the bacteria that is making you sick and gets rid of it.

Which is one event that may lead to Primary succession? clear-cutting climate change volcanic eruption introduced species
Answer:
Primary Succession is when an uninhabited area becomes an ecosystem, and Secondary secession is when an ecosystem is destroyed an Independent factor, like a fire, a hurricane, stuff like that.
Explanation:
Clear-cutting climate change would be an example of Secondary Secession, and volcanic eruption introduced species would be an example of Primary Secession.
Primary succession occurs when new land is formed or bare rock is exposed, providing a habitat that can be colonized for the first time.
The event that may lead to Primary succession is: volcanic eruption
What are the three causes of primary succession?The main causes of ecological succession include the biotic and climatic factors that can destroy the populations of an area. Wind, fire, soil erosion and natural disasters include the climatic factors.
What organisms come first after a volcanic eruption then what happens?Lava from a volcanic eruption hardens into bare rock. Primary succession begins with soil formation. The first stage of succession involves pioneer species. In primary succession, pioneer plants are those that can grow without soil, such as lichens.

what is the function in a cell of the carbon compounds lipids
Answer:
Lipids are organic compounds that consist of carbon, hydrogen, and oxygen. They are made up of fatty acids and other compounds. They provide cells with energy, store energy, and help form cell membranes.
Carbon, hydrogen, and oxygen are the main components of lipids, which are organic molecules. Fatty acids and other substances make them up. They aid in the formation of cell membranes, supply energy to cells, and store energy.
What is function of carbon compounds lipids in cells?In a cell, lipids carry out a variety of tasks. Cells store energy as lipids termed fats for long-term use. Lipids also insulate plants and animals from their surroundings.
All cells are fundamentally made up of lipids, which also serve a variety of crucial functions.
They are essential parts of the nuclear membrane, endoplasmic reticulum, Golgi apparatus, and trafficking vesicles like endospores and lysosomes.
As well as other cellular compartments, including the plasma membrane.
