Answer:
Many cells in the body have extensions of their cellular menbrana, which depending on their length can be cilia or microvilli, which are the shortest. We see the case, for example, the microvilli found in the small intestine, more abundant at the level of the second and third portions of the intestine, which favors the great absorption of liquids, proteins and nutrients that occur at this level.
Cilia are cellular structures that have a more defined formation and are characterized by their nucleus being made up of proteins and enveloped by the cytosol and plasma menbrana. They are presented as an appendix in the form of hair; We will find these cilia in the cells of the respiratory system and in the reproductive system where they help the mobility of foreign bodies (respiratory system) and the movements of sperm (reproductive system).
Answer:
yes. i agree. early puberty leads to early stress, depression and early sexual behavior.
Explanation:
For young people who begin puberty earlier than their peers, the transformation appears to be particularly fraught, especially for girls. Early-maturing girls are at increased risk of a range of psycho social problems including depression and early sexual behavior.The average age of a girl's first period in the United States and Europe was about 16 a century ago. Today, it's closer to 13.In boys, puberty begins between ages 9 and 14, on average, starting with growth of the sexual organs and wrapping up with facial hair and a deepened voice.
Karen Rudolph, PhD, at the University of Illinois at Urbana Champaign, and colleagues, followed more than 160 boys and girls for three years. They found that girls who matured earlier than their peers had increased rates of depression that persisted over the course of the study. They also found that while early-maturing boys initially had lower levels of depression than later-maturing boys, over time they showed signs of increased anxiety, negative self-image and interpersonal stress. By the end of the three-year study period, the boys' rates of depression were almost as high as those of the early-maturing girls (Development and Psychopathology, 2014).
Answer:
The semilunar valves open during the ejection phase due to the pressure on the left ventricle being higher than the pressure in the aorta and pulmonary artery.
Explanation:
During the ejection phase occurring in the ventricular systole, the pressure in the left ventricle increases and overpasses the pressure in the aorta and pulmonary artery. At this point the semilunar valves open, allowing the blood to flow from the ventricle into the arteries.
Answer:
Hanna will more than likely improve her function. My main issue with this principle is that it does not take into consideration the cyclical hypoxic nature of exercise. If Hannah does not have any respiratory issues than this will be beneficial but if she has problems in the regard this is a poor way to improve her condition.
Explanation:
New research shows the Vaso Diolators in conjunction with aromasin can greatly increase oxygen uptake and red blood cell proliferation which will help greatly to increase cardiorespiratory function. So maybe aromasin and VD stacked with that training would synergize the exercise.
The correct answer is D. Therapeutic index
Explanation:
In medicine, the therapeutic index is the range that defines the measure of a medicine that is safe or recommended as treatment and the measure that is toxic or has negative effects. This index is essential for the prescriptions of medicines because it acts as a guide to provide efficient treatments and toxicity. For example, the therapeutic index of paracetamol (painkiller) is between 10mg per kilo to around 150mg per kilo, which means taking doses above 150mg per kilo causes toxicity. According to this, the correct answer is the Therapeutic Index.
