What are the three of the fundamental assumptions of biological theories of crime causation?
Three of the fundamental assumptions of biological theories of crime causation are:-
1. Those that attempt to differentiate among individuals on the basis of certain innate or inborn outward physical traits or characteristics;
2. Those that attempt to trace the source of differences to genetic or hereditary characteristics; and
3. Those that attempt to distinguish among individuals on the basis of structural, functional, or chemical differences in the brain or body.
Biological theories within the field of criminology attempt to explain behaviors which are contrary to societal expectations through examination of individual characteristics.
These theories are categorized within a paradigm called positivism (also known as determinism), which asserts that behaviors, especially law-violating behaviors, are determined by factors largely beyond individual control.

What event was khrushchev speaking of when he said the world had come close to ""destroying the human race""?
The Cuban missile crisis was the event Nikita Khrushchev was speaking of when he said the world had come close to "destroying the human race".
The Cuban Missile Crisis, also known as the October Crisis of 1962, the Caribbean Crisis or the Missile Scare, was a 35-day (16 October – 20 November 1962) confrontation between the United States and the Soviet Union, which escalated into an international crisis when American deployments of missiles in Italy and Turkey were matched by Soviet deployments of similar ballistic missiles in Cuba. Despite the short time frame, the Cuban Missile Crisis remains a defining moment in US national security and nuclear war preparation. The confrontation is often considered the closest the Cold War came to escalating into a full-scale nuclear war.
In response to the presence of American Jupiter ballistic missiles in Italy and Turkey, and the failed Bay of Pigs Invasion of 1961, Soviet First Secretary Nikita Khrushchev agreed to Cuba's request to place nuclear missiles on the island to deter a future invasion. An agreement was reached during a secret meeting between Khrushchev and Cuban Prime Minister Fidel Castro in July 1962, and construction of a number of missile launch facilities started later that summer.
The missiles in Cuba allowed the Soviets to effectively target most of the Continental US. The planned arsenal was forty launchers. The Cuban populace readily noticed the arrival and deployment of the missiles and hundreds of reports reached Miami. US intelligence received countless reports, many of dubious quality or even laughable, most of which could be dismissed as describing defensive missiles.
Only five reports bothered the analysts. They described large trucks passing through towns at night that were carrying very long canvas-covered cylindrical objects that could not make turns through towns without backing up and maneuvering. Defensive missile transporters, it was believed, could make such turns without undue difficulty. The reports could not be satisfactorily dismissed.

For a biology project, you measure the weight in grams, and the tail length, in millimeters (mm), of a group of mice. the equation of the least-squares line for predicting tail length from weight is:________
The equation of the least-squares line for predicting tail length from weight is: predicted tail length = 20 + 3 × weight .
Determining how variation in morphology affects animal performance (and ultimately fitness) is key to understanding the complete process of evolutionary adaptation. Long tails have evolved many times in arboreal and semi-arboreal rodents; in deer mice, long tails have evolved repeatedly in populations occupying forested habitat even within a single species (Peromyscus maniculatus).
We use a combination of functional modeling, laboratory studies, and museum records to test hypotheses about the function of tail-length variation in deer mice.
First, we use computational models, informed by museum records documenting natural variation in tail length, to test whether differences in tail morphology between forest and prairie subspecies can influence performance in behavioural contexts relevant for tail use. We find that the deer- mouse tail plays little role in statically adjusting centre of mass or in correcting body pitch and yaw, but rather it can affect body roll during arboreal locomotion.
In this context, we find that even intraspecific tail-length variation could result in substantial differences in how much body rotation results from equivalent tail motions (i.e., tail effectiveness), but the relationship between commonly-used metrics of tail-length variation and effectiveness is non-linear.

Smaller neurons require more current to change their membrane potential.
a) true
b) false
This is false that Smaller neurons require more current to change their membrane potential.
A potential gradient known as membrane potential causes ions to passively migrate in one direction: positive ions are drawn to the "negative" side of the membrane, while negative ions are drawn to the "positive" side. Human life is impossible without membrane potentials. Over their membrane, every living cell maintains a potential difference. Simply said, differences in the concentration and permeability of significant ions across a membrane are what cause membrane potential.
A change in membrane potential results from a change in ion permeability. The membrane potential moves closer to the ion's Nernst equilibrium potential as permeability to that ion increases. The membrane potential is shifted away from the ion's Nernst equilibrium potential as permeability to that ion decreases.
The less probable it is that the arriving ions will collide with something that might cause them to bounce back, the bigger the axon's diameter of a neuron. Positive ions must continuously move away from the cell body in order for the action potential to exist, and this is made much simpler in a bigger axon.

Why does venous return from the distal arm travels in the superficial veins and those veins tend to bulge superficially in a person who is working out?
Blood distribution is adjusted by a short-term neural control mechanism to meet specific demands. During working out, the hypothalamus signals for reduced vasomotor stimulation of the skin vessels. Blood moves into the capillary veins, and heat radiates from the skin to reduce body temperature.
VeinsAll over your body, veins are blood vessels that collect blood with low oxygen content and send it back to your heart. Your circulatory system includes your veins. They cooperate with your heart, other blood vessels, and other organs to maintain blood flow. Most of your body's blood is stored in veins. Your veins actually contain around 75% of your blood. Veins have two basic functions. One function is to gather blood that is low in oxygen throughout your body and transport it back to your heart. The other function is to transport blood that is rich in oxygen from your lungs to your heart. Only during this process do veins transport oxygen-rich blood.

What is the arrangement of the phospholipids a substance encounters as it passes through the plasma membrane?
The phospholipids in the plasma membrane are arranged in two layers, called a phospholipid bilayer, with a hydrophobic, or water-hating, interior and a hydrophilic, or water-loving, exterior.
Phospholipids are a class of lipids whose molecule has a hydrophilic "head" containing a phosphate group and two hydrophobic "tails" derived from fatty acids, joined by an alcohol residue (usually a glycerol molecule). Marine phospholipids typically have omega-3 fatty acids EPA and DHA integrated as part of the phospholipid molecule. The phosphate group can be modified with simple organic molecules such as choline, ethanolamine or serine.
Phospholipids are a key component of all cell membranes. They can form lipid bilayers because of their amphiphilic characteristic. In eukaryotes, cell membranes also contain another class of lipid, sterol, interspersed among the phospholipids. The combination provides fluidity in two dimensions combined with mechanical strength against rupture. Purified phospholipids are produced commercially and have found applications in nanotechnology and materials science.
In aqueous solutions, phospholipids are driven by hydrophobic interactions, which result in the fatty acid tails aggregating to minimize interactions with the water molecules. The result is often a phospholipid bilayer: a membrane that consists of two layers of oppositely oriented phospholipid molecules, with their heads exposed to the liquid on both sides, and with the tails directed into the membrane. That is the dominant structural motif of the membranes of all cells and of some other biological structures, such as vesicles or virus coatings.
Phospholipid bilayers are the main structural component of the cell membranes.
In biological membranes, the phospholipids often occur with other molecules (e.g., proteins, glycolipids, sterols) in a bilayer such as a cell membrane. Lipid bilayers occur when hydrophobic tails line up against one another, forming a membrane of hydrophilic heads on both sides facing the water.
