Function of the polar bodies in oogenesis?

Although the polar bodies do not become anything they do serve a purpose in reproduction/oogenesis. The polar bodies are the byproducts of the primary and secondary oocyte at each point of meiotic division in oogenesis. The polar body allows for the oocyte to get rid of chromosomes while at the same time taking the least amount of resources (cytoplasm) from the oocyte. Each meiotic division serves as a means of moving the oocyte toward its need haploid number of chromosomes for fertilization. So you could say that the polar bodies function as a means of cellular structure conservation. They help ensure that the oocyte remains nutrient/resource rich while at the same time helping the oocyte reach its haploid number.


At what stage do chromosomes coil up and become visible?

Chromosomes coil up and become visible during the prophase stage of cell division. This coiling allows the chromosomes to become more condensed and easier to separate during cell division.


What the sequence of events in a spermatogenesis?

Spermatogenesis is the process of sperm cell development. It involves a series of steps starting with the division of spermatogonia (stem cells) into primary spermatocytes, followed by meiosis I to produce secondary spermatocytes, then meiosis II to form spermatids. Finally, spermatids undergo maturation to become mature sperm cells.


During prophase, when do spindle fibers become attached to the chromosomes?

Spindle fibers become attached to the chromosomes during prophase in the early stages of cell division.


How does one cell become many cells?

One cell can become many cells through a process called cell division, where a single parent cell divides into two or more daughter cells. This process allows organisms to grow, develop, and replace damaged or old cells. Cell division typically involves two main stages: interphase, where the cell prepares for division, and mitosis or meiosis, where the division of the genetic material and cytoplasm occurs.

How much post secondary do i need for a pediatrician?

To become a pediatrician, you typically need to complete a bachelor's degree, followed by a medical degree (MD or DO), which usually takes four years. After medical school, you must complete a residency in pediatrics, which lasts about three years. In total, this process generally requires at least 11 years of post-secondary education and training.


Do you have to take secondary education training if you want to be a kids doctor?

Secondary education typically refers to high school. To become a "kids" doctor (pediatrician), it will take four years for the bachelor's degree post secondary school, and four years of medical school. There will also be an additional three or more years to complete the internship and residency requirements.


Is that just a myth that one should complete the course of antibiotics?

No. Obviously not. If a patient does not complete a course of antibiotics, they run the risk of selecting for antibiotic resistant bacteria in their body. If these bacteria become infectious, stronger (more expensive) antibiotics will be required to treat the secondary infection.

Can secondary consumers become primary consumers?

A primary consumer will never become a secondary consumer. In an ecosystem, there is one primary consumer and one secondary consumer, just like there is only one producer. Each member of an ecosystem has its specific duty.
