Explanation:

A.P.E.X.

Answer 2

A description of the Paleozoic era is A. The rise of life.

What is the Paleozoic era?

The Paleozoic Era was a geological era that spanned from about 541 to 252 million years ago. It is often referred to as the "Age of Invertebrates" because it was during this time that the first major diversification of animal life occurred, and most of the animal life was invertebrates.

This era also saw the emergence of fish, amphibians, reptiles, and the first land plants. The Paleozoic Era ended with the largest mass extinction in Earth's history, known as the Permian-Triassic extinction event, which wiped out about 96% of marine species and 70% of terrestrial species.

The Paleozoic Era is a geologic era that began about 541 million years ago and lasted until about 252 million years ago. During this era, there were several major events that shaped the Earth's history and led to the evolution of new life forms:

During the early part of the Paleozoic Era, there was a sudden burst of new life forms, including many of the major groups of animals that we know today. This is known as the Cambrian explosion.

Therefore, A) Paleozoic era, is the correct answer.

Answers

Answer:

A.lytic

Explanation:

Lysogenic and lytic cycles are two cycles of viral reproduction. In the lysogenic cycle,  the viral DNA is incorporated into the host cell genome. Then, it can be passed on to the cell's daughter cells after it divides.

The other cycle of viral reproduction is called the lytic cycle. In the lytic cycle, the DNA is activated (transcribed). Viral particles can then assemble and replicate, and lyzing the host cell.

Explanation: its a bad effect on life.

Answer:

Negative

Explanation:

The mutation that causes color blindness is negative for many reasons. First off, not being able to see color can cause you to not be able to do certain things in life. For example driving, if you can't see the correct colors to know when to stop or go, you can't safely drive. There are also some jobs where colors are important. Such as jobs that have to do with fixing colored wire. It's also bad because of how it takes away one of our senses and holds us back from seeing things and completeness. People who are colorblind can not truly experience the world like a person who can see color can.

Tachar lo que no corresponda: a) la respiración celular es el proceso que llevan a cabo las células de LOS ANIMALES / TODOS LOS SERES VIVOS para INCORPORAR LA ENERGÍA LUMÍNICA / LIBERAR LA ENERGÍA QUÍMICA contenida en la glucosa

Answers

Answer:

a) la respiración celular es el proceso que llevan a cabo las células de TODOS LOS SERES VIVOS para LIBERAR LA ENERGÍA QUÍMICA contenida en la glucosa.

Lo que no corresponde es: "los animales" e "incorporar la energía lumínica"

Explanation:

La respiración celular es uno de los procesos más importantes para la vida, y no es propia sólo de los animales, sino de todos los seres vivos. La misma puede ser aeróbica o anaeróbica, dependiendo de la presencia del oxígeno.

Durante la respiración celular, se libera energía química contenida en la glucosa, no se incorpora energía lumínica. Lo que sucede es que es una reacción exogénica, lo que significa que se libera energía, que luego será ATP y servirá para otros procesos.

The following are sources of Earth's internal heat energy EXCEPT

a. Decay of radioactive isotopes
b. Primordial heat
c. pressure from overlying layers
d. Sun’s energy

Answers

B: Primordial heat is NOT a source of Earths internal heat energy.

The sun's energy is not a source of Earth's internal heat. So the correct option is D.

What is the earth's internal heat?

Nobody has even gotten close to directly examining the interior of the Earth. So there is disagreement among geophysicists as to how heated the Earth's core is. However, the speed at which earthquake waves, sometimes known as "seismic waves," move may reveal a lot to scientists about the composition of the Earth.

The solidity, liquidity, or partial solidity of these materials can also be determined using seismic data. Laboratory results, meanwhile, show what pressures and temperatures the materials inside the Earth should melt at.

The temperature of the Earth's core is thought to be between 5,000 and 7,000 degrees Celsius based on this information. That is far colder than the sun's inside, yet roughly as heated as the sun's surface.

Although the amount of heat created inside the Earth is immense, the amount of heat energy received from the sun is around 5,000 times stronger. The weather is influenced by the sun's heat, which ultimately leads to erosion. It is so paradoxical that although the heat of the Earth creates mountains, the energy of the sun gradually breaks them down again.

Therefore the correct option is D.

The presence of hydrogen bonds also makes water molecules more 'sticky' or in scientific terms cohesive and adhesive.
