Answer:
Scientist are making efforts from a very long timem to establish life outof the Earth and once they selected moon for that.
For human survival water and oxygen are two essential components. Scientsts from NASA have launched many programms to such as Apollo to land human on Moon surface, which was successful. Other programs were also run by NASA to make humans live and work their but it was important to find out the existence of water first to live in Moon. LRO satellite found the existence of water (lunar water) on the Moon surface but because of less funds and delayed in the program, the mission was dropped.
But according to me, humans should establish an outpost on the Moon as water resources already exist in the Moon and water regulates most of the process in human body. Oxygen is already 40percent by mass at lunar crust which can be extracted as scietist says. so, This will maiantain the environmetal condition on the Earth as well, if the population will shiftto Moon.
The bond that holds together the two amino acids is a peptide bond, or a covalent chemical bond between two compounds (in this case, two amino acids). It occurs when the carboxylic group of one molecule reacts with the amino group of the other molecule, linking the two molecules and releasing a water molecule.
Growth rate = birthrate - death rate
so, it will be 0 in this question !!
Answer:
A. excrete sodium ions, B. decrease ECF.
Explanation:
We study about the role of sodium and water retaining hormones in controlling extracellular volume. Several natriuretic hormones may also contribute to the volume regulation. One of the most important natriuretic hormone is atrial natriuretic peptide (ANP). It is a peptide hormone and is released by the cardiac atrial muscle fibers.
Overstretching of atria which can result from excess blood volume, is the stimulus for the release of ANP. Once released it enters into circulation and acts on kidneys to increase the glomerular filteration rate. It also decreases the absorption of sodium from collecting ducts. In other words it increases the secretion of Na+ along with water thereby reducing the blood volume and volume of ECF.
The excess loss of salt along with water helps to compensate for the extra blood volume.
ANP or atrial natriuretic factor (ANF) opposes RAAS i.e Renin Angiotensin Aldosterone System.
Vertebrates are part of the phlylum chordata.
