The size of actual bed is 75 inches

Explanation:

Scale refers to the ratio of the original dimension to the dimension on paper (miniaturised dimension). Since it is a ratio, it has no dimension.

Scale= original dimension/miniaturised dimension

Given that scale is 1:25

It means that every 1 inch on paper would correspond to 25 inches in reality.

The length of the model bed= 3 inches

Hence, the length of the original bed is 25*3 = 75 inches

∴ Length of the actual bed of the student is 75 inches.

Associations detected between measures of neighborhood environmental conditions and human microbiome diversity.
Musya8 [376]

Associations that were detected between measures of neighborhood environmental conditions and human microbiome diversity is shown below;

  • There was a regular, positive associations that between diversity and NDVI sd in regards to  mouth microbiome.
  • There was a constant, significant, and a negative associations that was said to exist between percent grassland and that of the diversity of the nose microbiome.

<h3>What are the other result?</h3>

Further result from the study of Amber L. Pearson<em> et al.,</em> (2020) reveal that the outcome for the mouth microbiome, she shows that a little effect of percent trees was seen on diversity and Clay loam soil was said to be negatively and positively associated or linked with rectum microbiome diversity, when liken to loam soil.

The study reveals that  no potential indicator taxon among NDVI quartiles was found and further research is needed.
