The answer will be A because mitosis usually separate the sister chromatids to sister chromosomes to form two diploid cells. In meiosis, the goal is to have four haploid cells. To form that, cells need to undergo cell division two times. In the case of meiosis I, sister chromatids stay joined together until it reaches meiosis II. Then, the sister chromatids will separate starting at anaphase II in meiosis II. For example, if you start with 92 chromosomes (46 chromatids) during meiosis I, at meiosis II you will have two cells with 46 chromosomes (23 chromatids). By the end of meiosis II, you should form 4 haploid cells that contains 23 chromosomes.
Answer:
A virus that has an outer wrapping or envelope. This envelope comes from the infected cell, or host, in a process called "budding off." During the budding process, newly formed virus particles become "enveloped" or wrapped in an outer coat that is made from a small piece of the cell's plasma membrane. Hope this helps!
Explanation:
Answer:
b) the wing assisted incline running theory postulates that wings were initially used to maintain balance while climbing up slopes
Explanation:
According to Wing-Assisted Incline Running ( WAIR ), proto-birds developed wings as it assisted in running specially on inclined planes. The forelimbs were modified as wings as they provided balance to birds while running at fast speed on slopes. They also used less energy as compared to just running.
There were two more theories, bottom up and top down. According to bottom up, proto-birds were ground dwellers and wings were used to maintain the posture while running. According to top down, proto-birds were tree dwellers and used wings to hop from branch to branch to evade predators and catch prey.
