Purpose and Background Cells divide in two ways, mitosis and meiosis. Mitosis is used to produce cells that are genetically identical to the parent cell for growth, asexual reproduction, or repair after injury. Cells that are produced by mitosis are diploid, meaning that they have two complete sets of chromosomes, one from each parent. Meiosis is used to produce haploid cells that have only one set of chromosomes, a mix of chromosomes from both parents. Meiosis produces cells that are genetically unique from their parent cells.…

Remember Learning Outcome: 02.04.01 List and describe the phases of meiosis. Section: 02.04 Topic: Meiosis 31. Which of the following represents the correct order of events during prophase I?…
Good Morning Team, Barb is correct. I have reduced the scope to 1 week on-site and allowing the credit from Diane to cover the service week. We will conduct the clinical discussions during our integration calls. Eric, I have attached the work that's being requested. Background on Emory St. Joseph's…
Inside the ovary there are ovules that contain megasporangium (2n) that produce megasporocytes (2n) that can undergo meiosis to produce four megaspores (n). Only one of the megaspores survives, remaining inside the ovule. Integuments surround the ovule closing off nearly all of the ovule except a small opening, known as the micropyle. The process creates the female gametophyte, the embryo sac, which among other things contains an egg and two polar nuclei. Wind or pollinators causes the pollen grain to land on the stigma where it forms the pollen tube which allows the two sperm to travel into the embryo sac.…
Providing Pediatric Preventative services through Telemedicine/Telehealth in school settings to increase access to care. Barriers to health care are so multifaceted that it can be difficult to determine one solution, however, an opportunity in reducing such barriers can be found in Telehealth. Telehealth makes primary care services more readily available and can be delivered and received from anywhere, albeit internet connection is needed. Many times access to health care can be limited by transportation. While only 66% of Maricopa residents reported having a primary care provider, that number is lower among minorities and may not be favorable among children.…
Mitosis is similar to binary fission in terms of results, chromosomes are replicated, copies are moved. The opposite ends of the parent cells separate giving rise to 2 daughter cells that are similar to the parent cell. Mitosis is the type of cell division that replicates gametes. It lowers the number of chromosomes by ½. When sperm fertilizes then it has full set of chromosomes.…
Telophase/cytokinesis occurs when there is no longer a mother/father pair together, After the completion of meiosis I, the cells are no longer diploid cells, but rather haploid cells. Meiosis II also has four phases including prophase II, metaphase II, anaphase II, and telophase II/ cytokinesis. Prophase II occurs when spindle fibers reform and attach to the centromeres. Metaphase II consist of the chromosomes lining up to prepare for the division of centromeres in the next phase.…
After being given instructions for the blood work and necessary health teachings, I offered to further discuss how the fertilized egg in her body would develop into a mature organism. She obliged. G1, the gap 1 phase is where the cell grows and carries out metabolic processes. S, the synthesis phase where the cell replication of its DNA occurs. G2, the gap 2 phase is where the cell continues to grow making preparations for the second major process: M, the mitosis.…
The first change includes nuclear swelling and clumping of chromatin to produce a fiberglass appearance in the nucleus, which is accompanied with hydropic changes in the cytoplasm. Affected cells often exhibit reticular ballooning and reticular degeneration. Ballooning degeneration is characterized by cell swelling and detachment from neighboring cells, increasing eosinophilicity, multinucleation, and cytoplasmic homogenization. Reticular degeneration involves cell swelling due to vacuolization (this causes the cytoplasm to appear clear), and cell lysis. Eosinophilic inclusion bodies form in the nucleus, which are composed of aggregated viral proteins.…
The teleological argument is an argument attempting to prove God’s existence based on the evidence of design and order in the universe. It works based on the belief that there must have been an intelligent designer, and the only being powerful enough to have created the universe is God. The argument is a posteriori and inductive; it looks at our experience of the universe and draws inferences from it. As they are based on inferences, these conclusions are statements of probability rather than perfect proofs. Many philosophers have worked on the teleological argument – for example, Thomas Aquinas and William Paley.…
A “Y” shaped region is formed. The whole DNA doesn’t split though, only a small…
4) In Mitosis the DNA replicates only one time in one cell division. On the other hand DNA replicates single time for two cell divisions. 5) Synapsis do not occurs in the Mitosis , While in the Meiosis suanapsis of Chromosomes is necessary in its step known as prophase. 6) In Mitosis the daughter cells obtained are 4 haploid cells , while in the process of Meiosis we get two diploid cells. 7) In mitosis the chromatids are very close to each other, while in Meiosis chromosomes are separated during the required steps of the…
1.1 Describe stages of development from conception to birth. When an egg is fertilised it is a single cell called a Zygote, in the next 24-36 hours the single cell will divide into two cells, 12 hours after it will divide into four cells, and will carry on dividing which forms a cluster of cells which are called a monula. Three – four days after it has been fertilised the monula will move from the fallopian tube and will enter the uterus. At about six days the monula will form a hollow cavity which is known as a blastocyst. The blastocyst will burrow itself into the uterus lining this is called implantation.…
What are the strengths of the teleological argument? The teleological argument is an a posteriori style of argument, also known as an empirical argument which uses the evidence using observations of the world through the five senses to argue the existence of God. The argument is based on an interpretation of teleology in which purpose or telos appear to exist in nature. The teleological argument suggests that, given this premise, the existence of a designer can be assumed, typically presented as God.…
After interphase, chromatin in the nucleus starts to contract in the phase known as prophase. Centrioles start moving to polar ends of the cell and fibrous extensions form from the centromeres, some of which will traverse the cell and will constitute the mitotic spindle. Immediately after prophase and prior to metaphase, the cell’s membrane disbands and proteins begin to latch onto the centromeres. This forms the basis for the kinetochores. Microtubules begin to attach at the kinetochores and…
