The correct answer is option B, Age of trees
The forest area is usually defined in terms of climatic condition prevailing with in it, the type of flora and fauna found, the area of the forest , its geography (including location, latitudes, nearby geographical features etc. ) and the geological conditions (soil type etc.). Age of the trees in its flora diversity is of no subsequent parameter to distinguish between two forest areas.
In biology, bacterial species can be subdivided into taxonomic groups.
In biology, various bacterial species can be subdivided into taxonomic groups based on their characteristics and genetic relatedness. These taxonomic groups include phylum, class, order, family, genus, and species.
For example, the bacterial species Escherichia coli belongs to the Enterobacteriaceae family, Enterobacterales order, Enterobacteriaceae class, and Proteobacteria phylum.

Answer:
Here are some explanations from 0nline so if you want rewrite in your own words
hope this helps :))
blood glucose-
"The control of blood sugar (glucose) by insulin is a good example of a negative feedback mechanism. When blood sugar rises, receptors in the body sense a change. In turn, the control center (pancreas) secretes insulin into the blood effectively lowering blood sugar levels."
"If the blood glucose level is too low, the pancreas releases the hormone glucagon. This travels to the liver in the blood and causes the break-down of glycogen into glucose. The glucose enters the blood stream and glucose levels increase back to normal. This is an example of negative feedback."
body temperature-
" Body temperature is regulated by negative feedback. The stimulus is when the body temperature exceeds 37 degrees Celsius, the sensors are the nerve cells with endings in the skin and brain, the control is the temperature regulatory center in the brain, and the effector is the sweat glands throughout the body."
"Body temperature is controlled by the hypothalamus in the brain. If the hypothalamus detects that the body is too hot, the response is that the body begins to sweat to try and reduce the temperature back to the correct level."
"Negative feedback (or balancing feedback) occurs when some function of the output of a system, process, or mechanism is fed back in a manner that tends to reduce the fluctuations in the output, whether caused by changes in the input or by other disturbances."
"Negative feedback brings a system back to its level of normal functioning. Adjustments of blood pressure, metabolism, and body temperature are all negative feedback"
This is true
The Human Genome Project was an international biological project that was created to determine the sequence of the human DNA, and locating and mapping the entire genes of the human genome in terms of structure and function. The Human Genome Project allows researchers to discover disease causing genes and possibly prevent or treat them. In 2001, the Human Genome Project researchers discovered a new tumor suppressor gene on human chromosome 7 which is involved in prostate and breast cancer. Also in 2000, researchers in Japan and Germany discovered the genetic code of human chromosome 21 and was identified to be involved with diseases such as amyotrophic lateral sclerosis, Down syndrome and Alzheimer's disease.
If a common plant in an ecosystem becomes diseased, the ecosystem may become unbalanced.
