The specific type of meiosis that forms sperm is called spermatogenesis, while the formation of egg cells, or ova, is called oogenesis. ... Just like spermatogenesis, oogenesis involves the formation of haploid cells from an original diploid cell, called a primary oocyte, through meiosis.
I would have to say (D.) if it's been 150 years.
Answer: D
Explanation: the axial filament is madeup of hundreds of fimbrils. It is an organ of locomotion in organisms. It is located between the cell membrane and the outer membrane thereby giving the organism the ability to make a twisting motion. Example of organism that possess axial filaments is the spirochetes
<u>Less reproductive </u><u>isolation </u><u>among populations that share similar </u><u>habitats</u><u>.</u>
What is habitat reproductive isolation?
- Habitat isolation is the term for when populations of a species move to a new habitat and settle in an area where they no longer overlap with other populations of the same species.
- When reproduction with the parent species stops, a new group emerges that is genetically and reproductively independent.
What factors affect reproductive isolation?
- The members of different species will be reproductively isolated by any factor that prevents potentially viable individuals from coming together.
- Different habitats, physical barriers, and a variation in the timing of sexual development or flowering are examples of the different types of barriers that can result in isolation.
