Answer:
The correct answer is option Complex neuroendocrine response.
Explanation:
Hypothalamus is the thermostat of the body as it regulates and maintains body temperature by responding to external signals or stimuli and adjusts the body temperature in a close one to two degree of 98.6 degree.
The regulation involves a different type of endocrine hormones and thyroid gland and receptors that help in signaling the increase or decrease of body temperature it involves neurons and hormones.
Due to the response of thermoreceptors and hormones is known as the neuroendocrine response. Hypothalamus Involves two or more hormones and several steps it known as a complex response.
Thus, the correct answer is a Complex neuroendocrine response.
Well, when chromosomes cross over during prophase 1 of meiosis, the homologous pair of chromosomes exchange segments of DNA which happen to be the genes. So the significance of crossing-over during prophase 1 is that it adds genetic variation to sexually reproducing organisms.
Answer:
-provides protection for a cell
-provides a fixed environment inside the cell.
-The cell membrane also provides some structural support for a cell.
Explanation:
They would be genetic diversity, species diversity, and ecosystem diversity.
