When the Sun was forming from a collapsing cloud of gas, gravitational contraction was a key energy-generation method for the sun. It actually became so strong that it sparked nuclear events.
How did gravitational contraction heat early Earth?Similar to how coal is burned, the process of gravitational contraction requires the production of heat through chemical processes. Gravity is an inverse square law force, which causes heat to be produced when it shrinks. Nuclear fusion, which is involved in gravitational contraction, produces a lot of heat.
How does the Sun generate energy today?Nuclear fusion occurs in the sun and produces solar energy. In the sun's core, fusion happens when the protons of colliding hydrogen atoms fuse to form helium atoms. A PP (proton-proton) chain reaction is what causes this process to produce such a large amount of energy.

What’s the Safest Lane on the Highway?The safest lane to drive in on a highway or interstate is up for debate. Look at a standard three-lane highway:
Right Lane: The right lane travels the slowest and seems to be the safest. However, this lane is also the busiest, has traffic entering and exiting a highway or interstate, and occasionally encounters roadblocks and stopped vehicles on the right shoulder.Middle lane appears to be the most congested due to the presence of vehicles on both sides. However, the center lane also provides the most room for turning for drivers who need to avoid a traffic hazard.Left lane should, in theory, have the fastest-moving traffic because it is the fast lane.

The severe reaction of the body to an infection is sepsis. This medical emergency poses a risk to life. Sepsis occurs when an infection you already have sets off a series of events that spreads throughout your body.
What Is Sepsis?
Sepsis is the body's overpowering and potentially fatal response to infection that can cause organ failure, tissue damage, and death. It is, in other words, your body's poisonous and hyperactive response to an infection. Sepsis is a medical emergency that calls for prompt diagnosis and treatment, just as heart attacks or strokes. Severe sepsis and septic shock can result from sepsis.
Sepsis may have been substituted with the term "blood poisoning." Sepsis is not properly described as blood poisoning. Learn more about blood poisoning and sepsis here.
In order to avoid infection, your immune system typically strives to combat any germs (bacteria, viruses, fungus, or parasites). Your immune system will attempt to combat any infections that may arise, though you may need assistance from drugs including antibiotics, antivirals, antifungals, and antiparasitics. For unknown causes, the immune system occasionally stops defending against "invaders" and starts to turn against itself. Sepsis begins with this.

The specificity of an antibody is due to
A) its valence.
B) the H chains.
C) the L chains.
D) the constant portions of the H and L chains.
E) the variable portions of the H and L chains.
It is to be noted that the specificity of an antibody is due to " the variable portions of the H and L chains." (Option E)
What is Antibody Specificity?Antibody specificity can be interpreted as either a measure of the quality of fit between the antibody-combining site (paratope) and the associated antigenic determinant (epitope), or as the antibody's capacity to distinguish between similar or even different antigens.
Each antibody is made up of four polypeptides: two heavy chains and two light chains that are linked together to create a "Y" shaped structure. The amino acid sequence of the "Y" tips differs widely amongst antibodies. The antibody's specificity for binding antigen is determined by this variable region, which consists of 110-130 amino acids.
During B cell growth, V, D, and J gene recombination produce unbiased antibody specificity. This technique produces potentially harmful autoreactive cells as a byproduct.

How do we derive the cash balance?We need to use the indirect method of preparing the statement of cash flows. This method starts with the net income and adjusts it for non-cash items and changes in current assets and liabilities. The formula is:
Formulas
Cash flow from operating activities = Net income + Depreciation expense + Decrease in accounts receivable + Decrease in inventory - Decrease in accounts payable
Cash flow from investing activities = - Purchase of equipment
Cash flow from financing activities = + Issuance of common stock
Cash balance at December 31, 2016 = Cash balance at January 1, 2016 + Cash flow from operating activities + Cash flow from investing activities + Cash flow from financing activities
Cash flow from operating activities:
= $38,000 + $8,000 + $3,000 + $10,000 - $20,000
= $39,000
Cash flow from investing activities = - $13,000
Cash flow from financing activities = + $100,000
