Answer:

B.in a controlled way

Explanation:

Fuels are all chemicals that, when reacting with oxygen (O2), undergo a chemical phenomenon called combustion, releasing a certain amount of energy in the form of heat. This energy must be released in a controlled manner, avoiding accidents and waste.

Every burning of a fuel is an exothermic (heat-releasing) chemical reaction, but the products that originate always vary according to the fuel used. Fuels can generally come from a variety of sources, such as animal, vegetable, water hydrolysis or waste. Regardless of origin, for fuel to be useful, energy must be released in a controlled manner.

Montano1993 [528]

Cells, like bacteria and archaea, that do not have a nucleus in their cells have traditionally been called prokaryotes.

<h3>What are prokaryotic cells?</h3>

Prokaryotes are organisms whose cell (or cells) are characterized by the absence of a nucleus or any other membrane-bound organelles.

Prokaryotic cells are opposed to their eukaryotic counterparts that possess a membrane-bound nucleus that houses their genetic material (DNA).

Examples of prokaryotes are as follows:

  • Bacteria
  • Archeaebacteria

Therefore, cells, like bacteria and archaea, that do not have a nucleus in their cells have traditionally been called prokaryotes.

If purple flower color is dominant in pea plants, a cross between P generation purple and white plants will result ina. all purp
matrenka [14]

Answer:

a. all purple flowers in the F1 generation.

Explanation:

According to the given information, the allele for purple flower color (lets assume P) is dominant over while the allele of flower color (p). When two pure breeding purple (PP) and white flowered (pp) plants are crossed, the F1 would have all "purple flowered progeny with genotype Pp".

According to the Mendel's law of dominance, the hybrid genotype exhibits the dominant phenotype. Here, the allele "P" is dominant over allele "p". Hence, the genotype "Pp" would exhibit purple flower color and all the F1 progeny would have purple flowers.
