In order to produce honey, the honey bees consume nectar and pollen from different flowers. Pollen is one of the richest and the purest natural foods, comprising all the nutritional needs of a honey bee, that is, carbohydrates, sugar, enzymes, protein, minerals, and vitamins.

Answer:
True
Explanation:
Normal flora are microorganisms that are regarded as resident organisms, which can be found on or in an individual and do not cause any disease.
the transient flora refers to microorganisms that are found on the skin or the hands which are there through direct contact with person or object, and are easily removed by routine hand hygiene. Example is Norovirus that can cause stomach flu.
Opportunistic pathogens are microorganisms such as the bacteria and virus, which can only cause infection when the immune system is down. This means that , these organisms can not cause any infection as long as the immune system is ok.
In this case, the normal and transient flora like Norovirus can only cause infection when the immune system is down. That is why they are regarded as opportunistic pathogens.
Answer:
Karyotype
Explanation:
A karyotype is a picture of all the chromosomes in an individual. These images are analyzed by geneticists to identify structural changes in the chromosomes or to identify differences in number as is the case for Down syndrome.
Karyotyping is used to identify certain genetic diseases associated with chromosomal aberrations. This is associated with the field of cytogenetics.
