Answer:

Closed Systems. The earth system as a whole is a closed system. ... Virtually no mass is exchanged between the Earth system and the rest of the universe (except for an occasional meteorite). However, energy in the form of solar radiation passes from the Sun, through the atmosphere to the surface.

Answer:

The earth is a closed system because only energy is naturally transferred outside the atmosphere.

Explanation:

A closed system is a system in which only energy is transferred with its surroundings. An open system, however, is a system in which both energy and matter can transfer.

Answer:

17. C " TAAGCTG". It would be the replication strand because A always pairs with T and C always pairs with G, so replication strands just have the opposite base as the original strand  

18. Transcription is the name given to the process in which DNA is copied to make a complementary strand of RNA. RNA then undergoes translation to make proteins. The major steps of transcription are initiation, promoter clearance, elongation, and termination.

19. Straight hair is controlled by a recessive allele because as you can see the one where is not shaded is the one that has the most. There are only 1 shaded circle or square, out of the 12 other circles or square that is not shaded. This means that it is the recessive allele because people are less prone to getting straight hair, as you can see in that diagram.

In which of the following ways is DNA replication different from DNA transcription? (4 points)
Margarita [4]

Answer:

<h3>Transcription copies the DNA into RNA, while replication makes another copy of DNA. Both processes involve the generation of a new molecule of nucleic acids, either DNA or RNA; however, the function of each process is very different, with one involved in gene expression and the other involved in cell division.</h3>

Explanation:

So,my answer is,transcription happens outside the nucleus,and replication happens inside the nucleus.

4. Describe the cell cycle and cell division and explain their importance to an organism.
Marianna [84]
<span>The main reasons why cell division is important in organisms are reproduction, repair and growth. Cell division is necessary in order for life to continue.
</span><span>
The length of the cell cycle is important because it determines how quickly an organism can multiply. For single-celled organisms, this rate determines how quickly the organism can reproduce new, independent organisms. </span><span>Most of the differences in cell cycle duration between species and cells are found in the duration of specific cell cycle phases. DNA replication, for example, generally proceeds faster the simpler the organisms. One reason for this trend is simply that prokaryotic have smaller genomes and not as much DNA to be replicated.</span>
