<span>Mitosis is the process that facilitates the equal partitioning of replicated chromosomes into two identical groups. Before partitioning can occur, the chromosomes must become aligned so that the separation process can occur in an orderly fashion. The alignment of replicated chromosomes and their separation into two groups is a process that can be observed in virtually all eukaryotic cells. Interfase must happen before mitosis can begin. Interfase is when the parent cell stores energy and becomes bigger so it can make the two daughter cells. </span>

Define the 3 main mechanisms in a “feedback loop”. (the names and what each does)
viktelen [127]

Explanation:

A feedback loop involves:

  1. a receptor
  2. control center
  3. an effector

The endocrine system involves chemical signalling via the secretion of molecules called hormones into extracellular fluid. They bind to chemical receptors in order to cause specific changes in target cells, these lead to changes in the body's internal environment called homeostasis. It includes the thyroid, parathyroid, pituitary, pineal and adrenal glands along with other regions. The bone, adipose tissue, heart, pancreas and liver are a few of the regions of the body which show endocrine function. The brain, or control center functions to receive and process the information from the receptor. Effectors receive the control center's command and illicits a response in the form of a feedback loop, that may oppose or enhance the stimulus.

Further Explanation:

During homeostasis the body maintains a constant internal balance in pH, temperature, blood pressure etc. Cells in a multicellular organism become specialized for particular tasks and communicate with one another in order to maintain homeostasis. Within the human body these are known as hormone cascades, where several complex steps occur- the tissues signal to one another with the use of hormones released by the endocrine system. For instance, the regulation (increase and decrease) of these secretions is achieved by negative feedback loops, where the release of certain substances during a cascade in turn halts the secretion of hormones at earlier stages.

Pathogen A has an ID50 of 50 particles, pathogen B has an ID50 of 1,000 particles, and pathogen C has an ID50 of 1 × 106 partic
klemol [59]

Answer:

Option A, pathogen A

Explanation:

ID50 is a way to measure the virulent efficiency of a pathogen. ID50 for a pathogen depicts the number of pathogens required to infect or cause the associated disease with in 50 percent of any population sample.

This means that 50 pathogens A can infect 50 percent  of any sample population.

While 1000 pathogen B and 1000000 pathogen C are required to infect 50 percent  of any sample population.

hence, Most virulent pathogen is Pathogen A
