Would evolution by natural selection be able to happen if there was NO variation within a species? Why or why not?​
scZoUnD [109]

Answer:

Natural selection

Darwin's theory was based on the mechanism of natural selection, which explains how populations can evolve in such a way that they become better suited to their environments over time.

Individuals have variations within their heritable traits. Some variations make an individual better suited to survive and reproduce in their environment.

If this continues over generations, these favorable adaptations (the heritable features that aid survival and reproduction) will become more and more common in the population.

The population will not only evolve (change in its genetic makeup and inherited traits), but will evolve in such a way that it becomes adapted, or better-suited, to its environment.

Explanation:

Natural selection is the process through which populations of living organisms adapt and change. Individuals in a population are naturally variable, meaning that they are all different in some ways. This variation means that some individuals have traits better suited to the environment than others. Individuals with adaptive traits—traits that give them some advantage—are more likely to survive and reproduce. These individuals then pass the adaptive traits on to their offspring. Over time, these advantageous traits become more common in the population. Through this process of natural selection, favorable traits are transmitted through generations.

What statements are true about the biological macromolecules.
photoshop1234 [79]

All biomolecules could be called carbon-based molecules.

The monomers of DNA are nucleotides.

Cell membranes are made, in part, from phospholipids.

The monomers of of starch are monosaccharides.

Explanation:

Biological macromolecules are giant carbon-based molecules. They are polymers made by complex condensation reactions linking them together.

These molecules are typically produced exclusively by living organisms and this is why they are called biological macromolecules.

They are usually classified as organic compounds for their linkage to living processes.

  • It is correct that all biomolecules are carbon-based molecules. They are primarily made up of carbon, hydrogen and oxygen with some other elements.
  • Deoxyribo-nuclei Acids are macromolecules that contains all information about the life of an organism. The DNA is located in the nucleus of cells and it is the genetic matter that controls life activities. The basic unit of DNA is the nucleotides.
  • Cell membranes are structural component of cells that helps to regulate the movement of materials in and out of the cell. They are made up of phospholipids.
  • Monomers of starch are monosaccharides. These are the simplest unit of  starch that cannot be further hydrolyzed. They are usually called simple sugars. Examples are glucose and fructose.
