Answer:
Short answer is primers are partially complementary.
Explanation:
Forward primer: 5'-AGTCTACTCGTAACCGGTTACC-3'
Reverse primer: 5'-TAAGGCATCATGGTAACCGGTT-3'
When we write reverse primer 5' to 3' we can easily see that
3'-TTGGCCAATGG---5' is complementary to the forward primers'
5'---AACCGGTTACC-3' sequence. So instead of binding to the template DNA these primers might bind each other resulting with reduction of efficiency of DNA amplification.
The example that shows an organism maintaining homeostasis is b. a person sweating on a hot day. Homeostasis is an organism's ability to maintain a stable internal environment irrespective of the external environment. When a person's body overheats, the body releases water as perspiration or sweat to cool itself down. Another example is when a person gets cold, the hair on his arms and legs, stand up straight - to trap air circulating round his body, and heat it up.
