The sympathetic division of the ans arises from the ________ region of the spinal cord.
Answers
The sympathetic division of the ANS arises from the cervical region of the spinal cord.
What is a sympathetic nervous system?The sympathetic nervous system is part of the autonomic nervous system, along with the parasympathetic nervous system.
The sympathetic pathway can be divided into three following components:
•The preganglionic neurons,
•The sympathetic ganglia,
•The postganglionic neurons.
It is essential for preparing the body for emergency response in endangering situations, also known as the “fight-or-flight” response.
To prepare the body for this type of response, the sympathetic system activates numerous complex pathways enable the adequate response to a threat or trauma.
Some of these physical effects include: faster breathing, increased heart rate and blood pressure, dilation of pupils, redirection of blood flow to important organs (e.g. brain and muscles) and increased sweating.

Answers
Mannose sugar occurs on the surface of some bacteria and fungi and can trigger the immune response.
Mannose is a type of sugar that can be found on the surface of certain microorganisms, including bacteria and fungi. When the immune system encounters mannose on these pathogens, it can trigger an immune response.
The immune response is the body's defense mechanism against foreign substances, such as pathogens. In the case of mannose, it can be recognized by specific receptors on immune cells, such as macrophages and dendritic cells. These receptors, called mannose receptors, bind to mannose molecules on the surface of pathogens.
The binding of mannose to immune cell receptors initiates a cascade of events that leads to the activation of immune responses, including phagocytosis (engulfing and destruction of pathogens), release of inflammatory mediators, and activation of immune cells.

In order to safely bring the fossilized remains of a yeti down the side of a snowy mountain, they are strapped to a sled - the combination of which weighs 972 N - then carefully lowered down the 19.8∘ incline. To ensure the fossil is not damaged, it is brought down the snowy slope at a constant 1.92 m/s Although the runners of the sled are smooth, they are not free of friction; the coefficient of kinetic friction between the runners and the snow is 0.107. Assuming the rope is kept taut and parallel to the incline, what must be the tension (in newtons) in it
Answers
The tension in the rope is calculated as 33.7 N.
Weight of sled and fossil, w = 972 N Inclination angle of slope, θ = 19.8°
Speed of sled, v = 1.92 m/s
Coefficient of kinetic friction between sled runners and snow, μ = 0.107
To find:
Tension in the rope, T The forces acting on the sled are the gravitational force (Fg), the normal force (Fn) and the force of friction (Ff). The normal force is perpendicular to the slope and equal to the component of the gravitational force perpendicular to the slope. The force of friction is parallel to the slope and opposite the direction of motion.
The net force acting on the sled is given by the expression:
F net = ma
Since the sled moves with constant velocity, a = 0.
Therefore, F net = 0. F net = Fg sinθ - Ff = 0⇒ Fg sinθ = Ff
Since the speed of sled is constant, work done by tension in the rope is equal to work done by frictional force.
Hence, T = Ff = μFn
Where F n = Fg cosθ = w cosθ
Putting all the values,
T = μw cos θ sinθ= sin 19.8°cos 19.8°= 0.3365T = 0.107 × 972 × 0.3365T = 33.7 N
The rope is 33.7 N. The given problem is related to the tension in the rope. The tension in the rope is calculated as 33.7 N.
To bring down the fossil safely down the slope, the tension in the rope is 33.7 N. The gravitational force is acting perpendicular to the slope and the force of friction is acting parallel to the slope. The normal force is the component of gravitational force acting perpendicular to the slope. The sled moves down the slope with a constant velocity. The force acting on the sled is equal and opposite to the force of tension in the rope. The force of friction is given by the expression,
Ff = μFn,
where Fn = Fg cosθ = w cosθ.
Therefore, the tension in the rope is calculated as 33.7 N.
To bring down the fossil safely down the slope, the tension in the rope must be 33.7 N.

Select EITHER lactose intolerance OR ABO blood groupings to describe how the distribution of alleles are related to the evolutionary history of a population.
Answers
The ABO blood group is a genetic variation that has evolved over time in human populations. The gene responsible for the ABO blood groups is located on chromosome 9 and codes for a protein that is expressed on the surface of red blood cells.
The ABO blood group system is a common genetic trait in humans that is determined by the presence of three alleles: A, B, and O. The A and B alleles are codominant, meaning that they both express their own phenotype when present in the same individual. The O allele is recessive to A and B, meaning that it is only expressed when two copies are present.
The distribution of ABO blood groups varies widely between different populations around the world. For example, individuals of European descent are more likely to have the A or B blood group, while individuals of African descent are more likely to have the O blood group. This variation is thought to be the result of natural selection acting on different populations over time.
Overall, the distribution of alleles for ABO blood group and lactose intolerance are related to the evolutionary history of human populations. These genetic variations have evolved in response to different cultural practices and environments, and have been shaped by migration, trade, and natural selection.

The consequence of treating the vector, before ligation, with calf intestinal phosphatase will be B. It would prevent the ends of the plasmids from being ligated.
Calf intestinal phosphatase is a phosphatase enzyme that is derived from the intestine of the calf. The function of this enzyme is to remove the phosphatases present in the 3' and the 5' of a DNA segment by cleaving them.
Vectors, such as plasmids, are treated with the calf intestinal enzyme in order to prevent the plasmid from being ligated again. In order to add our gene of interest to the vector, the calf intestinal phosphatase is added so that the vector binds to the gene of interest rather than itself.
