Answer:

The correct combination for the 3 key properties is:

a. must allow faithful replication.

b. must have informational content.

c. must be able to change on rare occasions.

Explanation:

Since every cell in one particular body essentially contains the same DNA, it has to be copied accurately every time a cell divides. The information that the DNA codes for is the proteins that get translated and accounts for every feature that organism will have. These rare changes are known as mutations and they are critical to introducing variation in the species and allowing them to evolve in response to environmental stimulation.

Hope that answers the question, have a great day!

A typical human cell expresses only about 5% of its genes at any time. The expression of a gene can be regulated during any step
ANTONII [103]

Answer:

Enzymes

Explanation:

The regulation of gene expression is the central dogma of life. It is a series or set of mechanisms in which genetic information in the DNA expresses in the form of RNA or protein. Cells give gene expression b different mechanisms as transcription, maturation of mRNA, and translation.

During these mechanisms, different gene-regulatory proteins are influenced. For example, a set of RNA polymerases that are proteins transcribe the DNA molecule during transcription. Transcription factors are also proteins that control the synthesis of proteins in the cell. These proteins are an enzyme that catalyse the gene regulation in the human cells.

Three-year-old-Joshua spits out his broccoli, scrunches his face and shouts, "Yuck!" His mother can’t understand why he has such
Natali [406]

Answer:

As we get older the number of taste buds decreases.

Explanation:

Gustatory cells or the taste buds contains the different sensory cells on the tongue. The papillae consists of all the taste receptors. The sweet, bitter, salty, umami and sour tastes are recognized by the receptors.

The different individuals have different taste because of the presence of the different taste buds. The number of the taste buds decreases the individual gets older. The children has more taste buds and can easily understand the taste of different things. Hence, Joshua dislikes the broccoli taste.

Thus, the correct answer is option (a).
