An 8 year old girl is brought to your office by her mother, who tells you that the girl has been complaining of a sore throat for 3 days. Thinking that the girl was developing a cold, she kept her daughter home from school with the hope that she would get better. She has become worse in the past day, however, developing a fever of 103 degrees F, a headache, and complaining of abdominal pain. As you examine her throat, you see that in addition to red and enlarged tonsils, that there are white patches on them, and that there are swollen lymph glands on both sides of her neck.
Answer:

Redness in throat with white patches
Headache
Chills
Loss of appetite
Cervical lymphadenopathy (swollen lymph nodes in the neck)
Swollen tonsils
Difficulty in swallowing food or water

Answer: Acute otitis media.
Explanation: This question is based on the opening section of Pirozzo and Del Mar (2001). They specifically say that "Acute otitis media is a disease of infancy and early childhood defined by the presence of inflammation and fluid in the middle ear and accompanied by at least 1 sign of acute illness."

I need some to calculate this for me.
Pro Tip 1: To calculate the % of cells at rest (in interphase), divide the number of cells in interphase by the total # of cells in the slide (cells in telophase may look like they are almost 2 cells, but you can still count them as 1).
# of cells in interphase ÷ total cells = % of cells at rest
Pro Tip 2: To calculate the % of cells dividing (or mitotic index), add up the cells in prophase, metaphase, anaphase and telophase. Divide that number by the total # of cells in the slide.
# of cells in PMAT ÷ total cells = % of cells dividing (or mitotic index)
Answer:
INTERPHASE PROPHASE METAPHASE ANAPHASE TELOPHASE % of Cells at Rest (interphase)
% of Cells Dividing (Mitotic Index)
Normal Lung
13 cells 2 cells 2 cells 2 cells 1 cell 65% 35%
Cancerous Lung 6 cells 5 cells 3 cells 3 cells 3 cells 30% 70%
Normal Stomach 10 cells 3 cells 3 cells 3 cells 1 cell 50% 50%
Cancerous Stomach 5 cells 5 cells 4 cells 4 cells 2 cells 25% 75%
Normal Ovary 9 cells 5 cells 3 cells 1 cell 2 cells 45% 55%
Cancerous Ovary 3 cells 6 cells 5 cells 3 cells 3 cells 15% 85%
Explanation:
The answers are also down below in the chart if that helps you better make sense of them.
There are 20 cells in each column, to find the ones at rest we simply take the first number in the column and devide it by the number of cells (in this case 20) once we find the percent of cells at rest, we subtract from 100 to see the cells deviding!

these minerals are formed through crystallization of molten materials which statement best describes these two minerals?
the mineral on the left formed from lava
the mineral on the right formed from magma
the mineral on the left has smaller crystals in the middle on the right
the mineral on the left cool more slowly than the mineral on the right
Answer:
The answer is D.
Explanation:
Just took the quiz and got it correct.
The correct statement is that the mineral on the left cool more slowly than the mineral on the right
The crystallization process is simply known as the way through which atoms are arranged to form a material with a crystal structure.
A ways minerals is formed is by:
Crystallization of magma or lava
The minerals that forms igneous rocks often solidify or freeze at different temperatures.
Magma are created underground, in the lower crust or upper mantle, due to the intense heat there.

What two major events occur during meiosis that give the new cells genetic variation
Genetic variation is increased by meiosis
Because of recombination and independent assortment in meiosis, each gamete contains a different set of DNA. This produces a unique combination of genes in the resulting zygote. Recombination or crossing over occurs during prophase.

The cell cycle is highly regulated and involves many steps to ensure that a cell is ready to divide. For this reason, cells cycle between interphase and mitosis. Suppose a cell culture of 1,000 cells is grown, in which the cells cycle every 24 hours. For a single cell, it takes about two hours from the formation of the dissolution of the nuclear envelope to the separation of two daughter cells.
Which of the following best describes the approximate number of cells in the culture that are in interphase, as well as the consequence of the severe disruption of interphase in mitotic division of cells within a tissue?
A) There are approximately 917 cells in interphase. Disruption of interphase will have no effect on mitosis because they are two completely independent processes.
B) There are approximately 83 cells in interphase. Disruption of interphase will lead to a faster and more efficient mitotic cycle, which will result in increased cell division and tissue growth.
C) There are approximately 917 cells in interphase. Disruption of interphase will trigger the cell to switch to a mitotic phase and repeatedly divide, which will result in the massive proliferation of the cells and heightened tissue growth.
D) There are approximately 83 cells in interphase. Disruption of interphase will result in the cell being unable to synthesize proteins and organelles required to divide, which will result in the cell not passing key checkpoints and ceasing to divide.
Answer:
The two major phases of the cell cycle include mitosis (cell division), and interphase, when the cell grows and performs all of its normal functions. Interphase is further subdivided into G1, S, and G2 phases. After the synthesis phase, the cell proceeds through the G2 phase.

Wild diploid wheat has seven chromosomes in its pollen. Discuss the major events that had to occur for tetraploid pasta wheat to have evolved. Describe the genome and fertility of pasta wheat (number and kinds of chromosomes).
Answer:
Tetraploid wheat evolved by allopolyploidization and subsequent diploid-like behavior due to cytological diploidization
Explanation:
Durum wheat (Triticum durum) or pasta wheat, is a tetraploid wheat species that has 28 chromosomes, i.e., seven pairs in each genome (2n = 4x = 28). Durum wheat was domesticated from wild emmer wheat, which originated by hybridization of two diploid wheat species with 14 chromosomes: Triticum monococcum (genome AA) and one wild progenitor (genome BB). Triticum durum is a typical example of evolution by hybridization and polyploidization, where the resultant tetraploid species has two complete sets of chromosomes. Allopolyploidization is one of the most common types of plant speciation. During meiosis, 28 chromosomes form 14 homologous chromosome pairs, because homologous chromosomes have developed 'restriction of pairing' (i.e., cytological diploidization). The restriction of pairing to fully homologous chromosomes ensures a correct meiotic behavior, which otherwise would be altered due to the high level of homology that still exists among chromosomes from different wheat progenitors.

In the covalent compound HCl, H—Cl, or H:Cl, which element has the greater electronegativity
Chlorine has a higher electronegativity than hydrogen, but the chlorine atom's attraction for electrons is not sufficient to remove an electron from hydrogen. Consequently, the bonding electrons in hydrogen chloride are shared unequally in a polar covalent bond.
Chlorine has a higher electronegativity than hydrogen, but the chlorine atom's attraction for electrons is not sufficient to remove an electron from hydrogen.
What is electronegativity?
Electronegativity is defined as property of an atom of a particular chemical element which has been a property to attract the shared electrons while formation of chemical bond. Atomic number is the only factor that can affect the electronegativity of an atom.
The subatomic particle which is negatively charged and that has been move freely or bounded is known as electron. Electron is a subatomic particle that contain negative charges and proton is the subatomic particle which contain positive charge. Electron does not contain fix shape and size.
Hydrogen is known as the most lightest known element and hydrogen is present in the form of gas and the atomic number of hydrogen is 1. The burning of hydrogen with oxygen in order to form water. Atomic number is the only factor that can affect the electronegativity of an atom.
Therefore, Chlorine has a higher electronegativity than hydrogen, but the chlorine atom's attraction for electrons is not sufficient to remove an electron from hydrogen.
