Answer:
The correct answer is option A. False.
Explanation:
John Scott Haldane described a property of hemoglobin which is termed as the Haldane effect. Displacement of carbon dioxide from the hemoglobin of blood by oxygen in the lungs. It promotes the removal of CO₂ from the blood. This process is the Haldane effect.
Decrease in the affinity of the oxygen to binding with hemoglobin in response to a decrease in blood pH due to increased CO₂ concentration in the blood. It is the Bohr effect.
Thus, the correct answer is option A. false.
Answer:
Negative feedback.
Explanation:
Body's homeostasis is maintained by two feedback mechanism known as positive feedback and negative feedback. Most processes in our body is controlled by the negative feedback mechanism.
The negative feedback mechanism in which the final product of the reaction decreases the further secretion of that product. In case of the body temperature rise, brain canter decreases the body temperature is controlled by negative feedback. The high level of the substance decreases its further secretion in case of maintenance of body temperature.
Thus, the correct answer is option (c).
Answer:
(D). oxytocin.
Explanation:
The hypothalamic-pituitary axis can be defined a pathway that plays a central role in regulation of various endocrine glands. Hormones released from hypothalamus stimulates pituitary gland, which in turns secrete pituitary hormones to regulate release of hormones from other endocrine glands.
Regulation of growth hormone (somatotropin), cortisol (adrenal hormone), prolactin, and T3 (thyroid hormone) is done by hypothalamic-pituitary axis.
Oxytocin is a peptide hormone, which is synthesized by hypothalamus and secreted by posterior pituitary gland. However, level of oxytocin is regulated by positive feedback in loop, in which hormone itself regulates its release and does not involves regulation by hypothalamic-pituitary axis.
Thus, the correct answer is option (D).
Gradually, came sushi and karate from Japan, and delicatessens from Italy and Germany, and 18 speed bikes from several European countries. Chinese food cooked and served by Chinese Canadians, not all of it authentic Cantonese or Szechuan or whatever, got steadily more popular as I grew up. And pizza. And espresso coffee. And holopchi from Ukraine and pyrogies from Poland. French perfumes. Mexican leather goods. Smorgasbords. All of these were virtually unknown to me when I was in grade 1, but were common by the time I was in university. I could go on and on. Other countries are going through similar experiences, some more slowly that Canada has, some actually a bit faster.
Then there are the subtler things, the ways of thinking and living. Yoga, tai-chi, zen, existentialism, deconstructionism, post-modernism, Marxism, supply side economics and on and on.
This world is a globalized one now, and it has been getting gradually more and more so for a long time. There is no going back. We learn to live together on Starship Earth or we exterminate ourselves.
Answer:
The best answer would be cognitive health (<em>thinking</em>)
Cognitive thinking is of or relating to the mental processes of perception, memory, judgment, and reasoning, as contrasted with emotional and volitional processes.
For children, they learn through experience per say, meaning that it is important to teach them to control their behaviors for the sake of their reasoning of how they deal with certain situations. Aggressive behavior must be controlled which is why it is important for children to learn to control it. Therefore, the best option would be, "Learning to control aggressive behaviors is important for children's cognitive health."
