1. which of the following describes the correct relationship between kidney function and blood pressure? 1. hypertension can occur if too little water is reabsorbed by the nephrons. 2. hypertension can occur if too much water is reabsorbed by the nephrons. 3. hypertension can occur if too little water is reabsorbed by the ureters. 4. hypertension can occur if too much water is reabsorbed by the ureters. **the third option is not correct. i am doing this for test corrections and the third option was wrong**

1. Hypertension can occur if too little water is reabsorbed by the nephrons.

Explanation:

Kidneys are special organs that expels out the unwanted harmful substance and excess water from our body. And nephrons are small tiny tubes in the kidneys.  

Drinking water is voluntary. Kidneys in order to preserve water has to keep the extra sodium to maintain the intramedullary hypertonicity. It is more possible that both high salt and low water intake will lead to increase in blood pressure resulting hypertension.

assuming that your periodic table has eighteen columns, you should highlight   the four elements in the third column from the left of the table.

neutral atoms of elements after calcium contain d electrons. the energy of d orbitals of a particular main shell lies between the energy of the s and p orbitals of the next main shell. for example, electrons in the have energy higher than those in the orbital while lower than those of the orbital.

by the aufbau principle, electrons fill orbitals one at a time, starting from those of the lowest energy. the orbital is therefore filled right after orbitals and before orbitals.  

potassium has electron configuration and calcium . the s orbital of a main shell holds a maximum of two electrons. the next element would thus have the electron configuration and satisfy the requirements.

a neutral atom of the element contains three electrons on top of the most recent noble gas element. it should thus be placed in the third column of the periodic table. both scandium and yttrium would satisfy the conditions. an aufbau diagram indicates that the 4f orbital is filled before the 5d. however, it appears that exceptions exists for both lanthanum and actinium. neutral atoms of the two d-block elements also demonstrate the and should be highlighted as well.
