The first life form found on earth were mostly bacteria. "For the next 1.3 billion years (3.8 to 2.5 billion years ago), the Archean Period, first life began to appear and the world's landmasses began to form. Earth's initial life forms were bacteria, which could survive in the highly toxic atmosphere that existed during this time."

olasank [31]
<span>63x The amount of magnification you see through a microscope is extremely easy to calculate. You just multiply the power of each lens the image travels through together. So you have the equation 630 = 10 * x where 630 is the total magnification and 10 is the magnification of the ocular lens. Now just solve for x by dividing both sides by 10 63 = x So the objective lens has to have a power of 63x for your total magnification to be 630x</span>

Why is dna so important?
zimovet [89]

Answer:

DNA contains the instructions needed for an organism to develop, survive and reproduce. To carry out these functions, DNA sequences must be converted into messages that can be used to produce proteins, which are the complex molecules that do most of the work in our bodies.

olchik [2.2K]

Answer:

D. physiological mechanisms are the basis of behaviors.

Explanation:

The example of the development of electric fields as part of the communication between some fish, shows the interrelation that exists between physiology and behavior. This physiological factor that fish have has an impact on their behavior. However, it is necessary to recognize that physiology does not act by itself, but needs to receive a stimulus from the surrounding environment. This way of communicating is called  electrocommunication, a fish generates through its physiology an electric field and a second individual receives that electric field with its electroreceptors.

From the image of the earth given, the approximate amount of insolation for 66.5°N is 12 hours (Option A). See the definition of insolation below.

<h3>What is insolation?</h3>

Radiation from the sun received in the Earth's atmosphere or at its surface is referred to as insolation. Only around 52% of this insolation makes it to the earth's surface. The remainder is absorbed by water vapor, dust, and clouds, or is reflected by the Earth's surface and dispersed by airborne particles.

Thus, understanding insolation (the quantity of energy that falls on a certain region) is critical for optimizing the output of solar panels, which absorb and convert this energy. Understanding insolation numbers can help you identify aspects like the geographic placement of solar panels and orientation to optimum production.
