Answer:Both birth rate and death rate will decrease.

Explanation:

Demographic transition: The process whereby a country moves from high birth and death rates to relatively low birth and death rates.

The decline in death rate is due to better economic and social conditions of the country which leads to control of pre-existing diseases, better medical facilities,more food production,increased jobs,better sanitation and hence better quality of life.

Decline in birth rate is due to improved quality of life and also could be due to availability of family planning services in highly developed countries.Moreover access to education especially in female population has created awareness regarding birth control.

Atropine is sometimes used to dilate the pupil for an eye examination. which receptor would atropine block?
grigory [225]

Atropine would block the receptor called muscarinic acetylcholine receptors present in the eye.

Atropine is the Anticholinergic agent which is also known as parasympatholytics. The activity of neurotransmitters at the receptors leads to pupil constriction.

Atropine is used to block these receptors that allow the pupillary muscles to relax. This causes the dilation of the pupil.

Atropine is the mydriatics that is used for pupillary dilation to conduct a detailed examination of eye diseases.

without this medication, the pupil will only dilate in the darkness. However, doctors cannot examine the eye problems as there is darkness as they need light for checkups.

Which reaction would you employ to build a disaccharide from two monomers of glucose?
GenaCL600 [577]

Answer:

D. dehydration synthesis

Explanation:

Dehydration means removing water, and synthesis means building or creating something. Therefore, the synthesis of dehydration is defined as removing water to build something. This process occurs by removing a molecule of -OH (hydroxyl group) and a molecule of -H to form H2O or water. This results in the covalent bonding of two monomers (small molecules) to form a polymer (larger molecule).

Dehydration synthesis uses condensation in the process and when this continues for a long period of time, a long and complex chain is formed, such as those of disaccharide or polysaccharides. It is also responsible for storing excess glucose molecules as well as larger polysaccharides such as starch and glycogen.

Coliforms thrive in exact environmental conditions like other pathogenic bacteria, thus often used to indicate whether they are bacteria found in drinking water and swimming pools that might end up causing infections.

Therefore the existence of coliforms in water easily indicates feacal contamination.
