3 to 15 years old children are recommended for immunization and vaccination.
Machines can be useful 'cause it converts one type of energy into other.
Hope this helps!
Answer:
Hypothesis
Hypothesis 1:Caffeine is a stimulant and will result in an increase in the typing speed of the participants.
Hypothesis 2:Caffeine is a stimulant and will result in a decrease in typing accuracy.
Hypothesis 3:The heart rate of the people will increase with the intake of caffeine.
Aim of the study
The aim of this study is to determine the following:
• The effect of caffeine on typing speed
• The effect of caffeine on typing and accuracy.
• The effect of caffeine on the heart rate of people.
Explanation:
new species can form through allopatric or sympatric speciation. the mechanisms of genetic drift will act more strongly on populations that are initially separated in allopatry than on those initially separated in sympatry.
<h3>What is
genetic drift ?</h3>
In a population, genetic drift refers to a shift brought on by chance in the frequency of an already present gene variant. Gene variations could completely vanish due to genetic drift, which would limit genetic diversity. Furthermore, it may lead to the widespread spread and even fixation of previously rare alleles.
<h3>Why does it happen?</h3>
The term "genetic drift" refers to haphazard changes in the population's gene variation frequency. Genetic drift occurs throughout time when the frequency of different alleles, or variable forms of a gene, fluctuates randomly. Allele frequencies are changed to account for these variations in allele presence.
