Answer:
Organisms maintain dynamic homeostasis through behavioral and physiological mechanisms. Which of the following statements is an accurate explanation of a negative feedback mechanism used by animals to regulate body temperature? C) A ground squirrel's hypothalamus detects changes in environmental temperatures and responds by activating or suppressing metabolic heat production
Explanation:
The temperature-regulating center of vertebrate animals is located in the hypothalamus. A ground squirrel's in there detects changes in environmental temperatures and responds by activating or suppressing metabolic heat production. Maintenance of homeostasis usually involves negative feedback loops.
Duplications are repeated segments of genetic materials that result from unequal crossing over during meiosis or through a replication error prior to meiosis. They usually occur when homologous pairs do not line up correctly or in chromosomes with a lot of repeat sequences. Duplication of a segment of a chromosome would result in Genetic variability during evolution due to gene duplication.
The small intestine is the longest part of alimentary canal with a length of 4.5 to 7 m and narrow in width, while the large intestine is the hinder-most part of the alimentary canal with a length of 1.5 m. it called the large intestine because it has a width of 4-6 cm.
