Demographers studying the current population of a particular country produce the age-structure diagram shown in the figure below: Which of the following conclusions is not supported by this diagram?

The birth rate has increased during the past 10 years.

Approximately the same number of boys as girls were born in the past 20 years.

The country has experienced two population "booms' approximately 25 years apart.

There are nearly twice as many 70-year-old men in the country as there are 70-year-old women.

hydroxyl -oh

alcohols, always polar, can form hydrogen bonds with h2o molecules

carboxyl -cooh  

cargoxylic acids, has acidic properties which is a source of hydrogen ions, found in cells in ionized for with a charge of oh-1

carbonyl > co

ketone if within skeleton, aldehyde if group is at the end of skeleton, k & a may be structural isomers, it determines 2 sugars (ketose & aldose)

amino -nh2

amines, acts as a base, it can pick up h+ ions from surrounding solution, ionized with charge of 1+

methyl ch2

addition to rna/dna affects and gene expression

phosphate -opo3 ²⁻

organic phosphates, contributes to negative charge to, molecule that it is a part of, and potential to react with h20

sulfhydryl -sh

thiols, cross-linking stabilize the protein, and it is structure

cells spend most of their time in interphase

1)

i))the process of preparing food by green plants in the presence of sunlight is called photosynthesis.

ii) leaf is the site for photosynthesis.

iii) it takes place as,

6h2o+6co2=c6h12o6+602

hey there hope i ,

the answer is heat
