Answer:
it would be Fragilariopsis curta because it is part of the diatom subspecies of algae and has a hard bone like silica shell making it more like a crustacean than a true algae
Answer:
B. The father did not contribute a sex chromosome to his daughter due to nondisjunction of the sex chromosomes. The daughter is XO and her only X chromosome came from her mother, who was a carrier.
A.The mother's X chromosomes failed to separate during meiosis, and the daughter inherited two X chromosomes with the Lesch-Nyhan mutation. The father contributed no sex chromosomes.
Explanation:
As seen in the question above, a little girl was diagnosed with Lesch-Nyhan syndrome, which is an X-linked recessive condition caused by a mutation in the HPRT1 gene responsible for purine metabolism.
The little girl's parents do not have the syndrome, and no one in the little girl's paternal family presented this syndrome, however, we know that the maternal grandfather of the little girl's mother had the syndrome, which means that it was the mother's genetic material that contributed to the development of the syndrome in the little girl. This was because the little girl did not receive any X chromosomes from her father, but she inherited the two X chromosomes from her mother that coded for the Lesch-Nyhan mutation. This happened because the mother's X chromosome disjuction did not occur during meiosis I.
As shown above, the father did not contribute any sex chromosomes to his daughter, which means that the daughter is XO and her only X chromosome came from her mother, who was a carrier.
Answer:
The steps involves making hypothesis, deriving predictions from the logical consequences and then carrying out experiments based on those predictions.
Explanation:
Step 1: make a observation .
Step 2: Formulate a statement or question.
Step 3: Form the hypothesis .
Step 4: make a prediction based on the hypothesis.
Step 5: test the hypothesis whether its true or not.
Step 6: use the results to conclude the experiment.
