Mr Ackah, a retired teacher had been recording consistent increase of blood pressure for the past five year. what accounted for
OleMash [197]

Answer:

Change in the vascular system.

Explanation:

High blood pressure occurs when the arteries in the human body system become rigid thereby making the blood pressure rise.

The cause for this situation particularly in older people is the changes in the vascular system or circulatory system.

This is said to be vasoconstriction which lowers the flow of blood in the circulatory system, thereby causing high blood pressure

Hence, since Mr. Ackah is a retired teacher, it is believed that he is an old man susceptible to changes in the vascular system or vasoconstriction.

Explain how the structure of the cells that you have studied give evidence if a creator
laila [671]
Hi!

So, assuming that you mean a creator as in a religious deity - we're going to run into problems here.

In order for something to be scientifically validated, it has to be proven scientifically by following the scientific method.

As science is based off the physical world, the things we prove must reflect that. The idea of a deity is something which lies <em>outside </em>the physical realm.

This means that any proof that we do find a 'creator', will simply just be something we now know about the physical world.

We can't have <em>scientific </em>evidence of something which we cannot prove <em>scientifically. </em>

With that said, unless there is context or a piece of information missing, the question is unanswerable.

Hopefully, this helps! =)
