What else can I help you with?
True or false fine hairlike extensions on the exposed or free surfaces of some cells are called microvilli?
True. Microvilli are fine hairlike extensions on the surface of some cells that increase the cell's surface area for absorption and secretion.
How can a liquid be distinguished from a fine powder?
A liquid will flow and take on the shape of its container, while a fine powder will not flow freely and will tend to form piles or clumps. Additionally, a liquid will have a consistent volume, while a fine powder may have variable volume depending on how tightly it is packed.
What is freezing melting condensing evaporating boiling and vaporizing?
Freezing and melting are related. Freezing is going from a liquid to a solid, and melting is going from a solid to a liquid. The energy used for this phase change is called heat of fusion. Condensing and vaporizing are also related in a similar way. Condensing is going from a gas to a liquid and vaporization is going from a liquid to a gas. The energy used for this phase change is called heat of vaporization. Evaporation and boiling are similar. Both refer to the change of a liquid to a gas, but evaporation takes place on the surface of the liquid, and boiling takes place on the entire mass of the liquid.
What are rocks called when they cool from lava at Earth's surface?
Extrusive igneous rock is formed from rapidly cooled lava at Earth's surface. Examples are obsidian and basalt.
In what ways does fine sand behave like a liquid?
It takes the shape of the bowl, just like a liquid does.
Which substances is called the 'liquid gold'?
Liquid gold is a fine suspension of gold in an oil used as paint.
What are examples of froth flotation?
Froth flotation is commonly used in mining to separate valuable minerals from ores. Examples include the flotation of sulfide minerals such as copper, lead, zinc, and nickel from their respective ores to produce concentrates. It is also used in the processing of coal, where froth flotation is employed to remove impurities and achieve higher thermal efficiency.
What is the best way to prepare a surface for painting using liquid sander deglosser?
To prepare a surface for painting using liquid sander deglosser, follow these steps: Clean the surface to remove any dirt or debris. Apply the liquid sander deglosser according to the manufacturer's instructions. Allow the deglosser to dry completely before painting. Sand the surface lightly with fine-grit sandpaper to smooth out any imperfections. Wipe down the surface with a damp cloth to remove any dust. Now the surface is ready for painting.
What makes a fluid a fluid?
A fluid is any substance that flows. Fluids can either be liquid or gases. You can tell whether a liquid is true because they form a flat surface. Fine solid do flow, except they form a heap.
What is covers the surface of the moon?
The material that covers the surface of the moon is called regolith, which is also called moon dust. Regolith is made up of the crushed fine powder of volcanic glass and rock fragments.
True or false fine hairlike extensions on the exposed or free surfaces of some cells are called microvilli?
True. Microvilli are fine hairlike extensions on the surface of some cells that increase the cell's surface area for absorption and secretion.
How do you spell things that are sprayed?
Sprays that come in cans use compressed gases to spray a fine mist. The mist is called an aerosol (tiny droplets suspended in the air). The sprays are likewise called aerosols or aerosol cans.Perfume bottles use a bulb to force air through the liquid, similarly picking up fine droplets of the liquid. This type of sprayer is called an atomizer.
Is ink a soid liquid or a gas?
Usually it is liquid but can be a very fine powder
What type of surface does the moon have?
The Moon has a rocky, dusty surface covered with gray-colored fine dust and broken rocks, known as regolith. It’s full of craters, mountain ranges, and flat plains called maria formed by ancient volcanic activity. There’s no atmosphere or water, so the surface is dry and exposed to extreme temperatures. 🚗 Want to explore new places on Earth (not the Moon)?

What do you call putting food through a fine sieve to form thick and smooth liquid?
To put food through a fine sieve or food mill to form a thick and smooth liquid is to puree. Parents who make their own baby food often puree the food.
Why is atomisation?
It is when an object or substance is changed into very fine particles. For example. A liquid in an aerosol can, is said to have been atomised when the can emits the liquid as a very fine spray.
What is the dust on the moon called?
The dust on the moon is called lunar regolith. It is a mixture of fine dust, soil, broken rock, and other materials that cover the surface of the moon.
