Answer:
The inputs can be material, such as the silicon used in the computer chips in a phone, or energy, which is used, for example, to manufacture and operate a phone. Outputs can be usable products or wastes, which must be disposed or recycled. A life cycle analysis of a cell phone also includes an analysis of its individual parts.

The main layers of Earths interior are the inner core, the outer core, the mantle and the crust.
<h3>What is the indirect evidence that helped us determine the layers?</h3>
Use of seismic waves is the indirect evidence that helped us determine the layers. When earthquakes occur they produce seismic waves.
The flow of matter occurs by convection. The dense crust subducts back into the mantle exert forces on crustal plates that then move, producing tectonic activity.
So we can conclude that The main layers of Earths interior are the inner core, the outer core, the mantle and the crust.

A balance is best used to measure a sample's mass.
Answer: C
Explanation:
Weighing balance refers to a measuring instrument which is used to measure the mass of the sample.
It has two pans. On one pan, the material to be weighed is placed, with adequate known loads on the other one to such an extent that the shaft will be in balance.
The distinction between the zero perusing and the perusing with the dish stacked demonstrates the contrast between burdens in scale divisions.
Such an instant weighing needs the arms be of equivalent length.
Answer:Flippered and charismatic, pinnipeds (which includes seals, sea lions, and walruses) are true personalities of the sea. Like whales, manatees, and sea otters, they are marine mammals, meaning millions of years ago their ancestors evolved from a life on land to a life at sea. Today, they remain creatures of both land and sea. Though able to walk on land, they are truly at home in the water. Strong flippers and tails propel them and a streamlined body helps them cut through the water efficiently.
It’s easy to tell the enormous, tusked walrus from other pinnipeds, but seals and sea lions are easy to confuse. The easiest way is to look at their ears—sea lions have small ear flaps while seal ears are nothing but small holes.

A punnet square can be described as a diagram which is made to predict the genotype as well as the phenotypes of the offsprings of a cross.
To study the epistatis nature of the pigmentation in bear, a punnet square was made and the results of the punnet square are shown above.
The results of the punnet square show that the cross between two bears will have the chances of producing 9/16 black bears, 3/16 brown bears and 4/16 white bears.
