Insect-pollinated flowers have sticky or spiky pollen grains to that they stick to the insect bodies [ so that when an insects visits another flower, the pollen grain will easily land on the stigma allowing pollination and fertilisation to take place ].
Macromolecules, or polymers, are formed by the combination of smaller molecules or monomers in a specific sequence. This is an energy requiring process called polymerization that produces water as a byproduct. Examples of macromolecules include nucleic acids, lipids, proteins and carbohydrates.
The correct answer is: place the pulse oximeter in the baby's toe.
Explanation:
A pulse oximeter is a non-invasive medical device.
It is used to determine the concentration of oxygen-linked haemoglobin flowing in through the peripheral arterial blood.
It is generally used in those parts of the body where the skin is thin, like the finger tip of hand, toe tip or the ear lobe.
The difference in the absorbance of infrared light by the haemoglobin molecules linked to oxygen and the haemoglobin molecules not linked to oxygen is used to determine the concentration of oxygen in the peripheral arterial blood.
As the child has a difficulty in breathing so, it is obvious the amount of oxygen that all its body cells receive is far less than the amount of oxygen needed by them.
