Answer:
A. Both waves carry energy and refract
Explanation:
There are two major types of waves viz; mechanical waves and electromagnetic eaves. Mechanical waves such as sound waves are waves that require a medium or matter to pass/travel through while electromagnetic waves like light waves do not strictly require a medium to travel i.e through vacuum.
Electromagnetic waves are transverse waves i.e their particles move perpendicularly to the direction of the wave while mechanical waves can either be transverse or longitudinal. All waves carry energy from one medium to another and are capable of refraction i.e. change of direction.
Therefore, both mechanical and electromagnetic waves carry energy and refract.
In a mid-av junction, the impulse will reach the atria and the ventricles simultaneously, so the p wave is hidden by the complex.
The definition of an urge is a strong or unexplained urge. An example of an urge is when you have the urge to go to Vegas. An example of an impulse is buying something without thinking. noun.
An urge is a sudden desire to do something. Unable to contain his impulses, he stared at the sea again. An impulse buys, or impulse buy, is something you didn't plan on doing but decided to do when you saw it. For a constant force, the momentum of a force is the product of the resulting force ΣF and the duration of that force Δt. The force impulse is the cause of the change in movement and therefore the change in impulse.

if there is a source of water and single celled organisms, life will be possible on that planet. The planet will need a atmosphere so 1. it will have its own gravity 2. and so that gas molecules ( including oxygen) will not be able to escape into space. the world population will be roughly 10.7 billion people so the planet will need to be spacious. A planet as described would be perfect if you take the right measures. if it has single celled organisms than its proven that it can and will sustain life. So, the planet has a water source, contains living organisms, is spacious, and has a atmosphere.
The Xylem transports water and minerals while the Phloem transport organic nutrients
Microorganisms in their digestive tracts hydrolyze the cellulose to individual glucose units.
Cellulose- The stable formation of plant cell walls is greatly aided by cellulose, a hard, fibrous, and water-insoluble polysaccharide. The fibrils (bundles of microfibrils) and microfibrils (bundles of polysaccharide) made up of cellulose chains make up the plant cell wall.
Glucose- The primary form of sugar in the blood, glucose serves as the body's cells' principal source of energy. Glucose may be produced by the body from other chemicals or it can be obtained from the meals we eat. The circulation carries glucose to the cells. Insulin is one of many hormones that regulate blood glucose levels.
