Answer:
B
Explanation:
In a command Economy, 1 is right. 3 and 4 are plain Rubbish.
Carbon is the only element that can form so many different compounds because each carbon atom can form four chemical bonds to other atoms, and because the carbon atom is just the right, small size to fit in comfortably as parts of very large molecules. ... They can even join "head-to-tail" to make rings of carbon atoms.
Answer:
As a cell grows, its surface area-to-volume ratio decreases
Answer:
With respect to the differences in the DNA sequence of six species, including the human one, it is true that the DNA sequences may vary but the aminoacid sequences are identical.
Explanation:
Options for this question:
- <em>The DNA sequences may vary but the amino acid sequences are identical.
</em>
-
The nitrogen bases in the nucleotides must also be different in each.
-
The process in producing additional DNA, replication, is identical in all six.
-
The process of producing DNA, or replication, varies due to the differences in the DNA codes.
The different species that exist have specific genomes for each of them, this is the <u>genetic information contained in the DNA varies from one species to another</u>, as can be seen in the scheme (see image). However, the genetic code is universal, and does not vary from one species to another.
The genetic code is found in the RNA molecule and is a sequence of nucleotides that, organized in triplets (codons), are responsible for the synthesis of specific amino acids. An RNA molecule contains the information necessary for protein synthesis.
The scheme shows the differences of five species with respect to the human, based on the respective DNA sequences. But what it does not show is a universally accepted truth, that the nucleotide sequence encoding an amino acid is the same for each of these species.
