A population of rhinos in Africa is 112. this year there were 17 births and eight deaths in the population. What is the change in population? Do we have a positive, negative, or zero change in population? How many members are in the new population?

Answer should contain the following information: work for calculating the change in population positive, negative, or zero change in population. work for calculating the new population

Answers

Explanation:

Why anti-poaching?

Rhinos have inhabited the African continent for over a million years and they play a huge role in their ecosystems. The illegal trade in powders made from their horns, which in some countries in Asia is still considered a medicine or simply a symbol of wealth, nearly led to the extinction of the African rhino.

In 1875, there were still more than 1,000,000 rhinos living in the vast grasslands of Africa. Today the populations of the two species of black rhino and white rhino are estimated to contain about 5,000 and 20,000 animals respectively. The senseless killings continue. Since 2007, the number of rhinos hunted in Africa has increased by almost 9,000%.

It is therefore our call to stop the slaughter of rhinos with all our might.

what is the difference in solubility of triglyceride and the products of their hydrolysis​

Answers

Answer: Triacylglycerols are the major constituents of oils and fats of both plant and animal origin.

Explanation:

Hope this helps.

The products of hydrolysis of triglycerides are fatty acids and glycerol. While fatty acids, like triglycerides, are insoluble in water, glycerol is soluble in water.

Why are triglycerides insoluble?

Triglycerides are esters of fatty acids and alcohol, mostly glycerol. The fatty acid chains are inked to the glycerol molecules with the help of covalent bonds.

This means that the triglyceride molecule is uncharged and will therefore remain insoluble in water but soluble in organic solvents.

Also, products of hydrolysis of triglycerides are fatter acids and glycerol. While fatty acids will remain insoluble in water, glycerol is soluble in water.

Glycerol is alcohol with 3 hydroxyl groups, this is why it is also called a polyol. They are able to hydrogen bonds with the nearby water molecules.

Therefore, triglycerides and fatty acids are insoluble and glycerol is soluble in water.
