Answer:
b. the use of DNA as the information storage molecule
Explanation:
Prokaryotic cells are the ones that lack the membrane-bound organelles and well-defined nucleus. Eukaryotic cells have the nucleus and other membrane-bound organelles. Most of the prokaryotic cells are smaller in size as compared to eukaryotic cells. Despite these differences, both prokaryotic and eukaryotic cells have DNA as their genetic material. DNA serves to store genetic information in both types of cells.
The hydrophilic molecules are the polar molecules which establishes the hydrogen bonding with the water molecules. Hence the hydrophilic molecules are water loving molecules. The hydrophobic molecules are unable to establish any hydrogen bonding with the water molecules. Hence the hydrophobic molecules are water repellent molecules.
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.

Answer:
The correct option is B. Activation energy
Explanation:
The activation energy is usually used to designate the minimum energy necessary for a given chemical reaction to occur, that is, the basic requirement for the reaction to proceed.
For a reaction to occur between two molecules, they must collide in the correct orientation and have a minimum amount of energy. As the molecules approach, their electron clouds are rejected. This requires energy (activation energy) and comes from the heat of the system, that, is, from translational, vibrational energy, etc of each molecule. If the energy is sufficient, the repulsion is overcome and the molecules are close enough for a rearrangement of the bonds of the molecules.
The concept of Activation energy was introduced by Arrhenius in 1889. Arrhenius suggested that molecules must prossess a minimum amount of energy to react. That energy comes from the kinetic energy of the clliding molecules. Kinetic energy serves to cause reactions, but if the molecules move very slowly, the molecules will only bounce when they collide with other molecules and the reaction does not happen. In order for the molecules to react, they must have a total kinetic energy that is equal to or greater than a certain minimum value of energy called activation energy.
