Quick Answer: Which Statement Represents The Major Concept Of The Biological Theory Of Evolution?

Which statement represents the major concept of the biological theory of evolution? A new species moves into a habitat when another species becomes extinct. Every period of time in Earth’s history has its own group of organisms.

What represents the major concept of the biological theory of evolution?

In biology, evolution is the change in the characteristics of a species over several generations and relies on the process of natural selection. The theory of evolution is based on the idea that all species? are related and gradually change over time.

What will most likely happen if there is a change in the first three subunits?

A portion of molecule 2 may be different. What would most likely happen if there was a change to the first three subunits on the upper strand of Molecule 1? DNA replication results in two copies of a double helix of DNA, while DNA transcription results in a single-stranded RNA molecule.

Which statement is best supported by the theory of evolution?

Which statement is best supported by the theory of evolution? Populations that have advantageous characteristics will increase in number.

Which statement provides evidence that evolution is still occurring at the present time?

Which statement provides evidence that evolution is still occurring at the present time? New varieties of plant species appear more frequently in regions undergoing climatic change.

Which statement best explains why some cells in the reproductive system respond to certain hormones?

Which statement best explains why some cells in the reproductive system only respond to certain hormones? These cells have specific types of receptors on their membranes.

Which statement best describes human insulin that is produced by genetically engineered bacteria?

Which statement best describes human insulin that is produced by genetically engineered bacteria? This insulin will not function normally in humans because it is produced by bacteria.

Which statements best describe the relationship between the terms chromosomes genes and nuclei?

Which statement best describes the relationship between the terms chromosomes, genes, and nuclei? Genes are found on chromosomes. Chromosomes are found in nuclei. Which of the following is a reason that the size of a cell is limited?

Which statement is basic to the theory of evolution by natural selection?

More individuals are produced each generation that can survive. Phenotypic variation exists among individuals and the variation is heritable. Those individuals with heritable traits better suited to the environment will survive.

Which is a major concept included in Lamarck theory of evolution?

Lamarckism, a theory of evolution based on the principle that physical changes in organisms during their lifetime —such as greater development of an organ or a part through increased use—could be transmitted to their offspring.

Which statement best explains the concept of natural selection?

The best description of the theory of natural selection is that some individuals have genes that increase their chances of survival and reproduction. These individuals are more likely to reproduce and pass on their genes, causing their genes to become more common in the next generation.

What evidence supports the theory of evolution?

Perhaps the most persuasive fossil evidence for evolution is the consistency of the sequence of fossils from early to recent. Nowhere on Earth do we find, for example, mammals in Devonian (the age of fishes) strata, or human fossils coexisting with dinosaur remains.

Which of the following provides evidence for evolution?

Five types of evidence for evolution are discussed in this section: ancient organism remains, fossil layers, similarities among organisms alive today, similarities in DNA, and similarities of embryos.

Which statement provides the most likely reason that a human has not yet been cloned?

Which statement provides the most likely reason that a human has not yet been cloned? Humans have DNA that is structurally very different from other mammals. Cloning can only be performed on animals that normally reproduce asexually.

Question: Who Created Biological Psychology Perspective?

The biological perspective is essentially a way of looking at human problems and actions. The study of physiology and biological processes has played a significant role in psychology since its earliest beginnings. Charles Darwin first introduced the idea that evolution and genetics play a role in human behavior. Contents1 Who is the proponent of biological […]

Quick Answer: How Are Biological Indicators Used In Environmental Science?

Bioindicators include biological processes, species, or communities and are used to assess the quality of the environment and how it changes over time. Bioindicator species effectively indicate the condition of the environment because of their moderate tolerance to environmental variability (Figure 1). Contents1 What are biological indicators and how do we use them?2 How are […]
