why can electromagnetic radiation travel through empty space?
Answer:
hello
Explanation:
Electromagnetic waves are waves that can travel through matter or through empty space. ... However, when light travels in matter, it interacts with the atoms and molecules in the material and slows down. As a result, light travels fastest in empty space, and travels slowest in solids.

Which of the following examples BEST describes the life characteristic of movement?
Human skin and lungs release carbon dioxide.
The oak tree takes in water and minerals for food.
The starfish cells divide and multiply to increase its size.
A cheetah races across the plain.
The statement that best describes the life characteristic of movement is human skin and lungs release carbon dioxide.
What do you understand by movement?Movement is an action of moving of any thing from one part or place to another part.
Life characteristic of the movement is shown by the human skin and lungs as skin opens and closes their pores time to time for the removal of gases and lungs also contracts and expands for the conversion of oxygen into carbon dioxide.
Hence, human skin and lungs release carbon dioxide is the life characteristic of movement.

PLS HELP UNIT TEST SCIENCE
Answer:
Binomial nomenclature definition is - a system of nomenclature in which each species of animal or plant receives a name of two terms of which the first identifies the genus
Explanation:
Why is it beneficial to use the scientific name of an organism? The binomial nomenclature has a number of advantages over using the common names.
What taxonomic levels are included in a scientific name? The Taxonomic levels, are a way of classifying species. In taxonomy, there are eight levels: domain, kingdom, phylum, class, order, genus and species.

Scott made a model of the water cycle by filling a tub with water, covering the tub with clear plastic, and placing a heat lamp over the tub. After a few days, he observed water droplets collecting on the plastic wrap.
What process formed the water droplets in Scott’s model?
evaporation
transpiration
condensation
precipitation
The phase change process of condensation formed the water droplets in Scott’s model.
What is condensation?Condensation is a process of phase change in which gas molecules are converted to liquid molecules.
Condensation occurs due to the loss in heat and hence kinetic energy by the gas molecules.
In the water cycle model, after evaporation occurred in the water molecules, the process of condensation
formed the water droplets.
Therefore, condensation resulted in the formation of water droplets on the model.

Okay So Blink your eyes. Was work done? Explain your answer.
I don't need you telling me this isn't a real question also I need this kind of work so please don't put anything that isn't useful for my assignment .
In physics, work is defined as a force causing the movement—or displacement—of an object. In the case of a constant force, work is the scalar product of the force acting on an object and the displacement caused by that force. Though both force and displacement are vector quantities, work has no direction due to the nature of a scalar product (or dot product) in vector mathematics. This definition is consistent with the proper definition because a constant force integrates to merely the product of the force and distance.
Answer:
no work was needed. Blinking does not require using energy sometimes we blink without thinking.
Explanation:
Answer:
Yes work was done because muscles in your body contract and relax to make you move and blink. To just smile you use 32 or 36 muscles. The simplest movements are also sometimes to most complex.

Imagine that scientists have found a planet with an outer layer divided into plates made of hard, solid rock, but the mantle below the plates is made of hard, solid rock instead of soft, solid rock as it is on Earth.
Do you think plate motion would take place on that planet? Why or why not?
The layer of planets is made of crust, mantle, and core. The tectonic plate motion on the newly found planet will not occur as it has a hard and solid mantle.
What are tectonic plates?Tectonic plates are defined as sold rocks that make up the mantle layer of the lithosphere of the planet. They are massive and irregular in shape that can move under high pressure and temperature conditions to form mountains and landscapes.
The plate tectonic of the planet is composed of hard, solid rock that will not be able to move or solid like that of Earth as they are hard enough to show the movement of sliding over each other unlike the soft, solid rock of Earth's lithosphere.
Therefore, the plate tectonic of the planet with hard, solid rocks will not show any movements.
