The endocardium consists of endothelial cells that controls myocardial function.
The homeometric and heterometric regulation is separated by myocardial system.
The endocardium also functions as a blood heart barrier thus controlling the ionic composition withih which the cadiomyocytes bathe.
The cost-benefit analysis done to investigate a proposed mine site would take into consideration the cost of environmental restoration after mining and the value of the ore to be extracted from the mine.
<h3>Cost-benefit analysis</h3>
This is an analysis done to assess the cost and benefits of actions.
For an action to be profitable, the benefits must be more than the cost.
In this case, for a mine site, the value of the ore to be extracted from the mine has to be more than the cost of having to restore the site after mining.
Every other cost can also come in but the two major ones are those highlighted.

Answer:
Soil texture tests would be - determine the percentage of sand, salt, and cay in the soil
nutrient test test would be - determine the amount of plant nutrients available in the soil
Organic matter tests would be - determine the quantity of organic matter in the soil sample
pH tests would be - determine whether soil is acidic or alkaline
Explanation:
If you read each of the drag and drop boxes carefully then you can find some small hints like the word acidic that related o pH and nutrients would go with nutrients.
