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.

Explain how technology has changed to improve the diagnosis of a person's health condition?
GenaCL600 [577]

Advancement in technology over the years has definitely helped in improving the diagnosis of a person’s health condition.

<u>Explanation:</u>

Internal injuries can be easily diagnosed using methods like x-Ray and scanning. Technological advancements have helped immensely in the field of oncology. Detection of tumors has become easy with the arrival of computerized tomography and MRI scanning.

CT scans give a better image of internal organs than X-Rays and detection of conditions like heart disease, cancer, emphysema, liver disease etc has become easier. Magnetic Resonance Imaging also gives a clear picture of the internal organs.

Which line from the text best supports the idea of a positive effect from plastics in the ocean? “surprisingly, there are some c
Bas_tet [7]
That line would be the first option - <span>“surprisingly, there are some creatures benefiting from all this plastic.” 
It is the only line which has a positive connotation because there are still some organisms which don't find plastics in the ocean to be a bad thing. The other options show only negative consequences of plastics being thrown in the oceans. </span>
