Explanation:
Nutrition imbalance can lead to a potentially dangerous set of symptoms known as the female athlete triad. A lack of sufficient nutrition can cause menstrual dysfunction. Menstrual dysfunction can cause hormonal imbalance. Hormonal imbalance can cause low bone density which ultimately causes osteoporosis.
Answer:
The order of development has been large brains, bipedalism, tool use, modern behavior.
Explanation:
A is not correct because the human ancestors had large brains before they become bipedal, which is not weird considering the fact that all primates have proprtionately large brains, even for mammals.
B is correct because the large brains were already a trait of the human ancestors, with the change of environment they developed bipedalism, with the further growth of the brain and anatomic changes in the fingers the humans developed tools, and last but not least came to modern behavior.
C is not correct because bipedalism occurred before the usage of tools.
D is not correct because the tool usage did not occur at the beginning of human evolution, but several million years later.
E is not correct because the bipedalism occurred later than the large brains, and the modern behavior came the last, not in the early stages.
Answer:
2. meiosis I only
Explanation:
During the zygotene stage of prophase-I of meiosis-I, homologous chromosomes synapse and are paired up. These paired homologous chromosomes are called bivalents. These paired homologous chromosomes align themselves at the equatorial plate of the cell during metaphase-I. Therefore, when observed through a microscope, cells are shown lined up two by two. During meiosis-II and mitosis, individual chromosomes with two sister chromatids are aligned at the cell's equator in metaphase.
Answer:
The difference between saturated and unsaturated fat lies in the number of double bonds in the fatty acid chain. Saturated fats are usually from animal sources, while unsaturated fats are usually from plant sources.
