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.

If a father is affected by an X-linked dominant condition and the mother is not, which children can inherit the condition?
kaheart [24]

Answer:

only females

Explanation:

In humans, sex chromosomes in males and females are different. The sex chromosomes found in humans are X and Y chromosomes. X-linked trait is a trait which is inherited on the X- chromosome. According to the question, the trait is passed on a X-linked dominant condition, which means the condition is inherited on the abnormal dominant X-chromosome that will express itself even when in an heterozygous state with a normal X-chromosome.

Hence, a father affected by the condition will have a genotype; XY while a mother that does not have the condition will have a genotype: xx (two normal x chromosomes). Since the Father can only pass his X chromosome to his daughters and never his sons, all his daughters will inherit the condition (see the punnet square in attached image).

N.B: None of the sons will inherit the condition since the mother will pass normal X-chromosomes (x) to her sons.

What is the rule of proteins?
Roman55 [17]

The function of a protein is determined by its shape. The shape of a protein is determined by its primary structure (sequence of amino acids.) The sequence of amino acids in a protein is determined by the sequence of nucleotides in the gene (DNA) encoding it.
