Answer:
The <u><em>second </em></u>line of defense.
Explanation:
In our bodies the <em><u>second line of defense</u></em> includes active immunity. It contains non-specific immune responses, but yet still contains specific responses for certain things such as inflammatory and fevers.
Answer:
It will remain relatively stable
Explanation:
<u>The carrying capacity (k) of an environment is a factor that represents the maximum number of organisms of a particular species such environment can support based on the resources it has. </u>
<em>Below the carrying capacity</em>, the population of a species still has the potential to increase due to resource availability, and <em>above the carrying capacity</em>, the population has the potential to reduce due to the overstretching of the available resources. Factors that keep the population from expanding significantly beyond the carrying capacity include competition for resources, natural disasters, disease outbreaks, etc.
<em>Hence, if a population is steady at its carrying capacity and a group of organisms from that species moves into the same space occupied by the original population, the carrying capacity will only increase temporarily before factors such as competition and natural disasters operate to bring the carrying capacity to the normal level. </em>

Answer:
a.There are three signaling pathway
1- Reception in which molecule binds to receptor
2- Signal transduction in which activation of intracellular pathway and enzyme occur.
3- Cellular response in which specific response of cell occur according to receptor and ligand.
b. Three types of receptors are
1- autocrine
2- paracrine
3- endocrine.
Explanation:
autocrine receptors are signaling pathway in which cell releases its molecule and bind to its own cell receptor example cancer cells while paracrine in which ligand binds to other nearby cell receptor and it is used during development and in endocrine cell target distinct cell and travel through blood stream like hormones functioning.
