Hey there!
Your answer is B. A one-celled organism that does not have a membrane-bound nucleus.
Prokaryotes are single-celled organisms.
They do not have a membrane around their nucleus like eukaryotes do. The region where the cell's DNA is located is called the nucleoid. The DNA is a single, circular chromosome.
Prokaryotes do have a cell wall, however they are single celled organisms.
Hope this helps!
As a genetic counselor, you note that every generation shows the trait, suggesting that the trait is dominant.
<h3>What is a domain trait?</h3>
A dominant trait is a genetic feature that exhibits the phenotype in a dominant manner for heterozygous individuals.
Dominant traits are well known to mask the recessive alleles in the population for a given phenotypic feature.
In conclusion, as a genetic counselor, you note that every generation shows the trait, suggesting that the trait is dominant.

Answer:
Prophase II meiosis-chromosomes-6 and 12 DNA molecules per cell.
Explanation:
Meiosis is a unique type of division that occur in cells in which the chromosome number is decreased to half with the creation of haploid cells. It can be referred to as reduction division and it mostly occurs in organisms which go through sexual reproduction.
In prophase II , the nucleoli and nuclear membrane disappear.
The chromatids reduces in length to become short and thick .
The centromeres migrates to the polar regions and set the spindle fibres in place for the second meiotic division.
Therefore, at Prophase II of meiosis
The daughter cells are haploid. Its haploid cells should possess six chromosomes and 12 DNA molecules.
Answer:
This a source which energy can be extracted, used and still be transformed maybe directly or into another energy form.
Explanation:
Different energy sources can be renewable and non renewable. Fossils such as coal and crude oil are the most common sources of energy in industries and homes. Here, we can cut down fuel requirements using burners, furnaces and engines that burn the fuel more efficiently.
Alternative sources of energy include hydroelectric power, nuclear energy, wind generators and solar panels. Wood, alcohol, could also be used as alternative sources of energy. Ad these are products of photosynthesis, they are renewable.
