You have seen how to use geometry and the properties of polygons to help you find unknown lengths and angles in various quadrilaterals and polygons. We will now extend this work to proving some of the properties and to solving riders. A conjecture is the mathematicians way of saying I believe that this is true, but I have no proof. The following worked examples will help make this clearer.
Given quadrilateral ABCD, with
and
, prove that
and
.
We draw the following diagram and construct the diagonals.
Given:
and
. We need to prove
and
. In the formal language of maths we say that we are required to prove (RTP)
and
.
In parallelogram ABCD, the bisectors of the angles (AW, BX, CY and DZ) have been constructed:
You are also given that
,
,
,
,
, and
.
Prove that MNOP is a parallelogram.
Given:
,
,
,
,
, and
. RTP: MNOP is a parallelogram.
MNOP is a parallelogram (both pairs opp.
's
, and therefore both pairs opp. sides parallel too)
It is very important to note that a single counter example disproves a conjecture. Also numerous specific supporting examples do not prove a conjecture.
Bacteria doesn't produce energy they are dependent upon their substrate in case of lack of nutrients they are able to make spores which helps them to sustain in harsh environments
_Adnan
But not all bacteria make spores, l mean Eukaryotic cells have Mitochondria which acts as powerhouse for them, since bacteria don't have it, what is the substitution for it?
Assimilatory nitrate reduction is a process that occurs in some microorganisms, such as bacteria and archaea, in which nitrate (NO3-) is reduced to nitrite (NO2-), and then further reduced to ammonia (NH3).
Elkana
This process is called assimilatory nitrate reduction because the nitrogen that is produced is incorporated in the cells of microorganisms where it can be used in the synthesis of amino acids and other nitrogen products
There are nothing like emergency disease but there are some common medical emergency which can occur simultaneously like Bleeding,heart attack,Breathing difficulties,severe pain heart stock.Hope you will get my point .Have a nice day ❣️

define infection ,prevention and control
Innocent
I think infection prevention and control is the avoidance of all things we do that gives out break of infections and promotion of health practices that promote life
