Compared to fingerprint evidence alone, DNA was far more likely to lead to suspects and result in arrests. In crime scenes where biological evidence was collected and tested, DNA evidence was five times more likely than fingerprints to yield a suspect and nine times more likely to lead to an arrest.
B. Nebulas
C. RR Lyrae variables
D. Cepheid variables
O When the body senses that the heart rate is very high, it secretes hormones that decrease the heart rate.
O When blood sugar concentration is too high, the endocrine system secretes hormones that decrease blood sugar concentration to a normal level.
O When someone is exercising intensely, the body secretes hormones that increase oxygen supply for cellular respiration.
The statement that describes a positivefeedback loop is as follows: when blood sugar concentration is too low, the endocrine system secretes hormones that increase bloodsugar concentration to a normal level.
A positive feedback loop is a feedbackloop that occurs in nature when the product of a reaction leads to an increase in that reaction.
A negative feedbackloop, on the other hand, occurs when increased output from the system inhibits future production by the system.
Therefore, the statement that describes a positive feedback loop is as follows: when blood sugar concentration is too low, the endocrine system secretes hormones that increase blood sugarconcentration to a normal level.

Answer:
The process of digestion in the human body takes place over six (6) steps. This travel log would be documented with each chapter as a step:
Day 1: Ingestion. I do not know how I got into this dark wet room (mouth) with huge white grinders (teeth), but I do not believe I would make it out in one piece; these grinders keep mashing me up n what I believe to be 'chewing'.
Day 2: Propulsion. There's a tunnel (oesophagus). I feel like I'm going down a wet slide.
Day 3: Physical digestion. I think I'm in some sort of sac-like mechanism (stomach)with thick walls that produce some sort of toxic substance (acids and enzymes) to my body. This is where I die.
Day 4 and 5: Chemical digestion and absorption. There is almost nothing left of me; I am being taking in by the walls of this maze (small intestine). More of the 'toxic' substance is coming from what appears to be leaf (liver) and all my constituents are being disintegrated (by the duodenum). Now there's a larger maze (large intestine or colon). I'm being separated and completely absorbed. The things that aren't useful about me (waste/stool) are being sent away.
Day 6: Defecation. Waste is excreted in the nus through the rectum.
I hope this was helpful.
