Iron rich deposits that formed about 2 billion years ago have red layers. Layers formed before then were not red. The red layers

formed when oxygen made during photosynthesis reacted with iron molecules in the ocean. The oxidized iron formed layers of sedimentary rock
. Which BEST summarizes this phenomenon?
A. The lithosphere changed the atmosphere. B. The hydrosphere change the atmosphere.
C. The atmosphere change the biosphere.
D. The biosphere change the lithosphere

Answer:

D. The biosphere change the lithosphere

Explanation:

The red formed due to oxygen which is produced by plants in the process of photosynthesis. This oxygen then reacted with iron atom and formed oxidized iron layers of sedimentary rock. So here plants are responsible for the formation of these layers and we considered plants as part of biosphere so we can say that biosphere is responsible for the change of lithosphere.

What is the remaining ratio of alleles? 2. Have any alleles been selected against?
Luden [163]

The remaining ratio of alleles is about 3:1

<h3>What about alleles?</h3>
  • The term "allele" is employed to refer to a gene's alternate form or variants.
  • For each autosomal gene, one allele is inherited from each parent, and that we often group the alleles into groups.
  • Usually, we ask them as normal, wild-type, aberrant, or mutant alleles.
  • For instance, a dominant allele can overcome the characteristics of other recessive alleles;
  • These features are what determine an individual's eye and hair color, for instance .
  • In this instance, the dominant brown eye alleles outnumber the recessive blue eye alleles.
  • Any of two or more genes that may alternately appear at a certain location (locus) on a chromosome is referred to as an allele, also referred to as an allelomorph.
  • Alleles may exist in pairs or there could also be many alleles influencing how a certain trait is expressed (phenotype).
  • Each gene during a human has two copies (or alleles), one from each parent.
  • Alleles significantly contribute to the event of each person's unique traits.
  • Alleles are variants of the identical gene with a minor difference in the DNA base sequence.
  • An allele may be a gene's variable form.
  • Some genes exist during a number of forms, all of which share the identical genetic locus on a chromosome.
  • Because each genetic locus in humans has two alleles—one acquired from each parent—they are referred to as diploid creatures.
