Answer:

During presentation of APC-bound antigen, macrophages and dendritic cells secrete the cytokine, interleukin-1, that activates T helper cells

Explanation:

Macrophages interact with T cells in order to generate T cell activation in target organs, and are themselves activated by inflammatory messenger molecules (cytokines) produced by the T cells.

Macrophages produce toxic chemicals, such as nitric oxide, that can kill surrounding cells.

During presentation of APC-bound antigen, macrophages and dendritic cells secrete the cytokine, interleukin-1, that activates T helper cells

According to this article, why does the immature prefrontal cortex lead to<br> conflict for teens?
aivan3 [116]

Answer:

The immature prefrontal cortex lead to  conflict for teens because the teenagers when they try to use the frontal lobe for reasoning, they tend to overdo it and then giving their brain much work to do. This leads to conflict in teens.

Explanation:

In teens, the prefrontal cortex is immature and develops until the mid-20s of their age. It covers the front part of the frontal lobe. As a result of the immaturity of the prefrontal cortex in teens, they do not think or make decisions like that of adults. When they try to overdo with their immature prefrontal cortex, they end up in conflicts.

The electric resistance pyrometer operates under the principle that an increase in temperature will cause an increase in the res
tatyana61 [14]

Answer:

operates om the principle of temperature-induced resistance.

Explanation:

In physical quantities, the resistance of an electrical conductor can be correlated directly with the temperature of the material. The property for the change in the resistance with temperature is called the temperature coefficient of resistance. Mathematically, the resistance of a material is given as follows:

R = R_{ref} [ 1 + \alpha (T - T_{ref})]

where R = conductor resistance at the temperature T.

Rreff = the conductor resistance at the reference temperature,

\alpha = temperature coefficient of resistance

T = Conductor temperature

Treff = reference temperature of the material.

From the equation, it can be seen that a positive coefficient for a material means an increase in the resistance of the material.

Courtney believes that the dinosaurs went extinct as a result of a giant asteroid hitting the earth. Scientists discovered a 150
Delicious77 [7]

This is a difficult question because the paragraph says that the scientists found the crater was dated back to the time the dinosaurs became extinct according to the fossil record, so that would make it true, but what it does not say is where they got the fossil record from or how the fossil record is correct, so that would make it false. So I would put it in as false.
