When the Grand Canyon was forming, a population of squirrels were separated into two groups. The north side of the canyon is at

a higher elevation and experiences more rainfall than the south side of the canyon. The two squirrel species you see here had a common ancestor, but over time, have evolved into two different species. How did natural selection lead to different species?
A) Because the squirrels were separated by the canyon, they were no longer able to reproduce and thus, became different species.
B) When the squirrels were separated, some of them acquired traits better suited for their new environment. This allowed them to survive and reproduce better than others. Over time, each group evolved to display unique traits for their different environments until one species evolved into two.
C) When the squirrels were separated, there was variation within each group. Some had traits that made them better suited for their home environment. This allowed them to survive and reproduce better than others. Over time, each group evolved to display unique traits for their different environments until one species evolved into two.
D) When the squirrels were separated, new mutations introduced variation within each group. Squirrels on each side of the canyon had different mutations. This allowed them to survive and reproduce better than others. Over time, each group evolved to display unique traits for their different environments until one species evolved into two.

Natural selection lead to different species when the squirrels were separated, some of them acquired traits better suited for their new environment. This allowed them to survive and reproduce better than others. Over time, each group evolved to display unique traits for their different environments until one species evolved into two.

Explanation:

The speciation in the squirrels due to the barrier in canyon occurred due to this. Such speciation is called allopatric speciation.

Speciation leads to formation of new species from the existing species due to change in their habitat or physical structure.

The squirrels on the two different side of canyon adapted to the habitat they are in. Their reproductive cycles, habitat and adaptation mode has become different due to the change in environment.

The species of squirrels became two as they reproduce and passed on the traits for survival in the environment which they had adapted.

The squirrels have become <em>reproductively isolated</em> also.

Genetic divergence takes place due to natural selection as squirrels arenow two different species.

Answer:The Answer Is C

Explanation:

When the squirrels were separated, there was variation within each group. Some had traits that made them better suited for their home environment. This allowed them to survive and reproduce better than others. Over time, each group evolved to display unique traits for their different environments until one species evolved into two.

Acylhomoserine lactones used in quorum sensing regulate their own synthesis by a(n) _________ system. Multiple Choice riboswitch
zmey [24]

Acylhomoserine lactones used in quorum sensing regulate their own synthesis by an autoinduction system.

  • Numerous bacteria use acyl homoserine lactones (acyl-HSLs), significant intercellular signaling molecules, to track the density of their population for quorum-sensing control of gene expression. The LuxI family of proteins produces the signals in question.
  • A lot of proteobacteria use quorum-sensing signals from acyl-homoserine lactones.
  • Cells create a baseline amount of signal at low population densities, and when enough signal has accumulated in the environment, it binds to its receptor and activates quorum-sensing-dependent genes.

gregor mendel law of segregation states the factors or genes seperate from each other during meiosis true or false
Mashutka [201]
True. Law of Segregation is one of the principles of herdity formulated by Gregor Mendel. It states that genes from a pair of homologous chromosomes separate during meiosis and then distributed to different gametes.
