From a sociological perspective, deviance:
Question 46 options:
A)
originates in society, not in individuals
B)
is an adaptation to the social structures in which people live
C)
needs to be responded to by making changes in society
D)
all of the above
Answer:
B
Explanation:
Deviance is where people don't blend into societal norms and cultures for various different reasons, meaning A cannot be the answer. C is not always applicable, and we can see this in the fact that clearly society isn't changing significantly every time there's someone deviant (or we'd have no need for prisons). This makes D also impossible, leaving the only answer that is plausible to be answer B.

Sort the following events into two categories:________.
1. Carcinogenic—changes that could cause cancer
2. Anti-carcinogenic—changes that could stop cancer
a) activation of cyclin gene expression
b) activation of a phosphatase that affects kinase 3 of the MAP kinase pathway
c) activation of a phosphatase that affects p53
d) activation of DNA synthesis genes
e) blocking GTPase activity of the G-protein α subunit
f) blocking degradation of p53
g) blocking dimerization of PDGF receptors
h) blocking cyclins from binding to cyclin-dependent kinases
Answers:
a) carcinogenic
b) anti-carcinogenic
c) carcinogenic
d) carcinogenic
e) carcinogenic
f) anti-carcinogenic
g) anti-carcinogenic
h) anti-carcinogenic
Explanation:
Cyclins are proteins that regulate the progression through the cell cycle, i.e., the transition of G1 to S phase. It is well known that high cyclin expression may lead to cell proliferation states, which is closely associated with cancer progression. Moreover, the blockage of cyclins may have an anti-carcinogenic effect by inhibiting the progression through the cell cycle. MAP kinases are serine/threonine kinases that regulate the progression through the cell cycle by phosphorylating a variety of substrates during cell proliferation. In consequence, phosphatases that inactivate MAPK kinases (i.e., by dephosphorylation) may have an anticarcinogenic effect. The p53 is a tumor suppressor protein involved in diverse cellular processes including DNA repair, cycle arrest and programmed cell death. This protein (p53) is activated by phosphorylation at target residues and phosphatases inactivate it, thereby the blockage of its degradation may have an anticarcinogenic effect. Oncogene activation (i.e., the expression of oncogenes), may alter diverse cellular processes including DNA replication, and thereby may lead to cancer development. The G-protein α subunit is a GTPase that hydrolyses GTP and thus has a major role in controlling the kinetics of the G-protein signaling cascade. Platelet-derived growth factor receptors (PDGFR) are kinase receptors that play roles in regulating cellular differentiation, cell proliferation and cell growth. PDGFR receptors are present on the surface of normal cells, however, it has been shown that mutations of the PDGFR genes that lead to their high expression lead to uncontrolled cell growth and consequently cause cancer (i.e., by increasing PDGF signaling).
The cell in the diagram is part of what sort of tissue?
Answer:
Tissue is a group of cells that have similar structure and that function together as a unit. Primary types of body tissues include epithelial, connective, muscular, and nervous tissues. Epithelial tissues form the covering of all body surfaces, line body cavities and hollow organs, and are the major tissue in glands.

which action has the least impact on the environment
The action has the least impact on the environment is using a safe fountain for clean drinking water.
Which action has the least impact on the environment?The action has the least impact on the environment is using a safe fountain for clean drinking water. The plants use sunlight, water, and carbon dioxide to make sugars as well as food. Organisms can be divided into autotrophs and heterotrophs according to their pathway of producing food and energy. Heterotrophs are that organism which depend on another organism for their food and energy. They get their energy from carbohydrate, protein, and fat.
Those organisms that are able to make and produce energy from energy-containing organic molecules such as glucose from inorganic raw material such as water and by using light energy such as sunlight are autotrophs. Plants are the prime autotrophs, they produce their food and energy which is sugar from water, sunlight and carbon dioxide using photosynthesis.
Therefore, The action has the least impact on the environment is using a safe fountain for clean drinking water.

Answer:
The liquid portion of the blood is called Plasma
Answer: Plasma
Explanation:
Blood plasma is a yellowish liquid component of blood that holds the blood cells of whole blood in suspension. It is the liquid part of the blood that carries cells and proteins throughout the body. It makes up about 55% of the body's total blood volume

23. Macromolecules containing large amounts of hydroxyl groups (-OH) have less potential energy than molecules that are largely hydrocarbons, which of the following best explains why?
a) Carbon – Hydrogen bonds are short and very strong
b) Carbon – Hydrogen bonds are long and comparatively weak
c) Oxygen – Hydrogen bonds are long and comparatively weak
d) Hydroxyl groups are easily removed in enzyme-catalyzed reactions
Answer:
b) Carbon-Hydrogen bonds are long and comparatively weak
Explanation:
Carbon-Hydrogen bond is a covalent bond between a carbon and hydrogen atom in which carbon shares its valence electrons with four hydrogen atoms.
Carbon-Hydrogen bonds are long and carbon-hydrogen combine together to form several long chain organic comounds such as methyl, ethyl, isopropyl, and benzyl etcetera but are comparatively weak.
Electronegativity affects the bond stregth of the hydrogen bond and there is small difference in electronegativities of the Carbon-Hydrogen that makes it comparatively weak.
Hence, the corrrect answer is "b) Carbon-Hydrogen bonds are long and comparatively weak".

Answer:
recessive, recessive
A recessive allele is hidden if present with a dominant allele, or visible if present with a recessive allele.
What do you mean by Allele?An Allele may be defined as one or two or more alternate forms of a given gene.
A recessive allele is masked when present with a dominant allele, while it may express when present in a purebred recessive condition.
Therefore, a recessive allele is hidden if present with a dominant allele, or visible if present with a recessive allele.

A 17-year old girl was admitted to the hospital with a 1-week history of fever, chills, malaise, sore throat, skin rash, and polyarthralgia. She reported being sexually active and has a 5-week history of a profuse yellowish vaginal discharge, which was untreated. Upon presentation, she had erythematosus maculopapular skin lesions over her forearm, thigh and ankle, and her metacarpophalangeal joint, wrist, knee, ankle, and midtarsal joints were acutely inflamed. She had an elevated leukocyte count and sedimentation rate. Cultures of her cervix were positive for N. gonorrhoeae, but blood specimens, exudates for the skin lesions, and synovial fluid were all sterile.
Why were the synovial fluid cultures negative?
a. This organism cannot be cultured on artificial media
b. The arthritis is a non-suppurative sequala
c. The organism is difficult to recover from synovial fluid beyond the first few days of inflammation.
d. It should have grown. The lab made a critical mistake.
e. It should have grown. The nurse mislabeled the sample.
Answer:
C. The organism is difficult to recover from synovial fluid beyond the first few days of inflammation.
Explanation:
why not A
The organism N. gonorrhoeae can be cultured on Thayer Martin Agar( a selective medium used for the isolation of gonococci (Neisseria gonorrheae) from specimen containing a mixed flora of bacteria and/or fungi), from following
I.urine samples,
II. urethral swab
III.orcervical swab.
therefore A is wrong
Why not B
Arthritis is both suppurative (infectious) as well as non- suppurative.
Why C
The organism is very difficult to recover from synovial fluid, but the presence of immune cells confirms the gonococci in the fluid.
