Answer:
In the 1960s, China's large population was growing so rapidly that there was a serious threat of mass starvation.
• The government established the world's strictest family planning and birth control program, promoting one-child families and provides contraceptives, sterilizations, and abortions for married couples.
• Married couples pledging to have no more than one child receive a number of benefits including better housing, more food, free health care, salary bonuses, and preferential job opportunities for their child.
• Between 1972 and 2011, the country cut its birth rate in half and trimmed the average number of children born to its women from 5.7 to 1
Explanation:
A. Hormones act as signal molecules between all body systems
Peripheral Chemoreceptors (Carotid + Aortic Bodies) and Central Chemoreceptors in the Medulla Oblongata detect high Carbon Dioxide levels in the blood during exercise. The respiratory centre in the Medulla Oblongata + PONS stimulate the intercostal muscles and the diphragm to contract in order to increase the rate and depth of breathing as to decrease levels of Carbon dioxide in the blood.
The thyroid gland secretes thyroxine which speeds up metabolism (the rate at which cells use glucose)
Answer:
Sodium and water move into the cell
Explanation:
Sodium and water move into the cell. This is because
Cellular damage result in failure of the Na+/k+ pump, allowing movement of sodium ions into the cell. This concentration of sodium pulls water in, resulting in hydropic swelling. Cellular damage results in the cell's inability to perform normal metabolic functions because APT decreases and Osmotic finally pressure increases.
Answer:
The correct answer is- founder effect
Explanation:
Founder effect occurs when a small number of individual isolates from the majority of the population by natural calamity or any other region. These isolated individuals show less genetic diversity than the larger population because they are less in numbers.
Therefore founder effect makes a small group of individuals isolate from a bigger population and make them occupy a different habitat. So a founder population can go on a newly developed island and start reproducing there.
A founder population over time converts into a new species because of reproductive isolation from the main population. So the evolution of life on the island of Hawaii should have been most strongly influenced by founder effect.
