Solution:

The carbon cycle is the biogeochemical cycle by which carbon is exchanged between the biosphere, geosphere, hydrosphere and atmosphere of the Earth.

It is based on carbon dioxide (CO2), which can be found in air in the gaseous form, and in water in dissolved form. Terrestrial plants use atmospheric carbon dioxide from the atmosphere, to generate oxygen that sustains animal life.

Thus this is the required path where carbon atom involves in the carbon cycle.

(03.05 MC) In which of the following ways is DNA replication different from DNA transcription? (2 points) New cells can only be

timama [110]

We presented with several statements after the question. Only one of these statements are correct.

DNA replication is the process in which a single strand of DNA, acting as the parent strand, forms two new strands of DNA. DNA transcription is the process of copying the information of the DNA strand and delivering this information into a strand of mRNA. These processes may sound similar, but there are key differences. We must look at the building blocks of DNA and RNA. Both structures are composed of four different bases, however, only three of these bases are shared between structures and they each have a unique fourth base. In DNA, the fourth base is thymine and it is uracil in RNA. We already established that DNA replication forms new strands of DNA, which would use thymine by default. DNA transcription results in formation of mRNA which would therefore use uracil.

The correct statement from the choices provided is the following:

Thymine is used in replication while uracil is used in transcription.

Two different plant species each carry 36 chromosomes (total) in their somatic cells. Species A is diploid, and species B is tri

ollegr [7]

Answer: Species A is diploid, it means 2n=36, the haploid number is 36/2=18. Species B is triploid, it means 3n=36, then the haploid number is 36/3=12.

Explanation:

A chromosome is an ordered bundle of DNA associated with proteins such as histones, and it is found in the nucleus of the cell. Different organisms have different numbers of chromosomes. Humans, for example, have 23 pairs of chromosomes, 22 of them are autosomal pairs, and one pair are sex chromosomes, which indicates the sex of a person. Each parent contributes one chromosome from his or her autosomal pair and one from the sex pair, so that the offspring get half of their chromosomes from their mother and half from their father.

<u>A haploid cell has only one set of chromosomes (n), whereas diploid cells have two sets of chromosomes (2n) and triploid cells have three sets (3n). In the example of humans, a diploid cell is a somatic cell and has 46 chromosomes (or 23 pairs). And a haploid cell, a gamete for example, has 23 chromosomes. </u>

If two species of plants carry 36 chromosomes, and species A is diploid, it means 2n=36. Then the haploid number is 36/2=18. Species B is triploid, it means 3n=36. Then the haploid number is 36/3=12.
