Answer:
Angiosperms
Explanation:
As per the evolution of plants the order is moss (Bryophytes), fern (Pteridophytes), Gymnosperm, and Angiosperm. Bryophytes are the most basic plant with only the capability of photosynthesis. Pterdophytes are an upgrade with being able to transport water and nuterients from the ground into vascular tissue. Gymnosperms and Angiosperms both are seeding plants , but angiosperms use flowers to reproduce.
Because it's where they live.
Answer: Option C. consists of ancestor species and all of its descendants groups.
Explanation:
Monophyletic clade refers to a group composed of a collection of organisms, including the most recent common ancestor of all those organisms and all the descendants of that most recent common ancestor.
A monophyletic clade is also called a taxon. By classifying organisms based on their biological diversity and evolutionary history, we can easily know, how different organisms, both past and present, are related to one another. Examples of monophyletic groups include: Mammals, birds, angiosperms, and insects.
Answer:
The correct answer is option C, that is, in the mother in meiosis II.
Explanation:
A nondisjunction in meiosis I produce all the aneuploid gametes, while nondisjunction at meiosis II produces 50 percent aneuploid gametes and the 50 percent normal gametes comprising haploid number of chromosomes.
As it is mentioned that one of the brothers possess normal number of chromosomes (46), the mother encounters nondisjunction at meiosis II resulting in the formation of one n+1 gamete exhibiting two copies of X chromosome. Fertilization of this n+1 gamete with sperm results in the creation of zygote (47, XXY).
