Meiosis is the process in sexually reproducing organisms where cells divide. The cells produced during meiosis have half the chromosome number as the original cell. There are two cell divisions in meiosis‚ meiosis l and meiosis ll. These cell divisions produce 4 hapolid daughter cells. Haploid cells contain only one set of chromosomes‚ which is written as n. Meiosis consists of nine phases. In meiosis the interphase l the chromosomes replicate and the centrosome duplicates in one diploid cell

Mahavira asserted existence of unseen microbiological creatures living in earth‚ water‚ air and fire.[20] Jain scriptures also describe nigodas‚ which are sub-microscopic creatures living in large clusters and having a very short life and are said to pervade each and every part of universe‚ even in tissues of plants and flesh of animals.[21] However‚ the earliest known idea to indicate the possibility of diseases spreading by yet unseen organisms was that of the Roman scholar Marcus Terentius Varro in a

Any foreign object that is introduced until environment that was not previously there can be pollution. This is why I believe bioscience is both beneficial not only to individual that enjoys fishing in natural habitats‚ but also to the world because it can reduce the amount of influence we have on natural environments. This will ensure they will be around for many

Question: How does mitosis produce new cells‚ and how is mitosis the same and different? Materials: - Compound microscope - Alliums root slide - Whitefish embryo slide - Power supply Procedure: Refer to page 48 and 49 in the textbook. Results: See attached sheet for drawings of my results. Discussion: Analyze and interpret question 1 and 2 on page 49. 1. The cells in the root tip region of the alliums differ quite a bit from the cells that are found deeper in the root

Mitosis: (onion roots) Root cells are good for observing mitosis; this is because they’re in the tip of the root which is an area of the plant that grows quickly. This results in more cells going through mitosis all at once‚ also allowing us to examine the different stages of mitosis. Stages: 1. Interphase: DNA replicates‚ but has not formed the condensed structure. They remain as loosely coiled chromatin. The nucleus is still intact. 2. Prophase: The DNA molecules progressively shorten

While increasing the mitochondrial pool is impertinent for a healthy pool of mitochondria with exercise‚ removing the damaged mitochondria is equally as important. During exercise it is well known that mitochondria release ROS that can be harmful when accumulated 76. If the dysfunctional mitochondria are not removed efficiently it will lead to an accumulation of harmful organelles. Studies have examined improper
