Paraphin [41]

Answer:

DNA

Explanation:

DNA is a nucleic acid. It is a polymer of deoxyribonucleotides that are bonded together by phosphodiester bond to make long DNA strands. DNA is the most stable biomolecule in the history of life on earth and continues to serve to store the genetic information of living beings. Several species-specific sequences are DNA are conserved during evolution. This makes the DNA the best molecule to store any valuable information.

RNA is comparatively more reactive and prone to mutations due to the presence of ribose sugar and uracil base in it. The structure of a protein is determined by DNA nucleotide sequences. Any change in DNA would also change the structure of a protein.

Hummus is an important component of healthy soil. how does hummus form?
denis23 [38]

Answer:

Humus (hummus) is a dark organic matter in the soil which is produced by the decay of leaves or twigs (leaf litter). The litter is decayed in the soil by the action of microbial communities and chemcial reactions (together called as biogeochemical reactions). This process is also known as decomposition. The higher humus content in the soil makes it more fertile because there are more nutrients releasing due to increased turnover of the decomposing bacteria. Further, humus formation is increased if more water (moisture content) and oxygen is available.

djyliett [7]

Letter A

Letter B

Letter C

Letter D

Letter E

Explanation:

<em>1. Darwin defined evolution as descent with modification meaning that species change over time, give rise to new species and share a common ancestor. (letter A)</em>

<em>2. Since the natural selection is mechanism proposed bay Darwin for evolution, based on the fact that resources are limited in nature, organism with heritable traits that favor survival and reproduction tend to leave more offspring than their peers, causing to increase  in frequency over generations. (Letter C and E)</em>

<em>3. Natural selection causes populations to become adapted, or increasingly well-suited, to their environments over time. It depends on the environment and requires existing heritable variation in a group. ( Letter D)</em>

<em>4. Natural selection can be considered a mechanism of change since the suviving group will determine the caracteristics of the next generation. Moreover  after several generations of selection, the population might be made up entirely different, according to the environment, the inheritage and improvement of the specie. ( Letter B)</em>
