Where is hereditary information for most traits found?

genes
Hereditary information is contained in genes, located in the chromosomes of each cell. Each gene carries a single unit of information. An inherited trait of an individual can be determined by one or many genes, and a single gene can influence more than one trait. A human cell contains many thousands of different genes.

Which is the best explanation for the decrease in the amount of energy transferred to each succeeding level?

Energy decreases as it moves up trophic levels because energy is lost as metabolic heat when the organisms from one trophic level are consumed by organisms from the next level. Trophic level transfer efficiency (TLTE) measures the amount of energy that is transferred between trophic levels.

When an organism reproduces asexually usually has?

Asexual reproduction involves one parent and produces offspring that are genetically identical to each other and to the parent.

Which statement best describes what will most likely happen if the amphipod?

Which statement best describes what will most likely happen if the amphipod population is removed from this food web? Population sizes of species at feeding levels after amphipods will decrease and before amphipods will increase.

Which statement best describes what is most likely to occur if an animal population?

Which statement best describes what is most likely to occur if an animal population grows larger than the carrying capacity of its environment? The birth rate will increase.

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.

Which statement best supports 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 best explains why some cells in the reproductive?

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 correctly describes the offspring of asexual reproduction?

Which statement correctly describes the offspring of asexual reproduction? They result without the fusion of gametes.

Which statement best describes the theory of evolution?

Which best describes evolutionary theory? It is based on the idea that all life is related. It states that organisms have become less complex over time. It is not supported by observation or experimentation.

Which statements is most closely related to the modern theory of evolution?

Which statements is most closely related to the modern theory of evolution? Organisms best adapted to a changed environment are more likely to reproduce and pass their genes to offspring. species of organisms found on Earth today have adaptions not always found in earlier species.

Which statement best describe the process of evolution?

Which statement best describes the process of evolution? Populations can survive in different locations on earth. Environmental conditions limit the number of species on Earth.

Which statement best describes evolution by natural selection?

According to Charles Darwin’s theory of evolution by natural selection, organisms that possess heritable traits that enable them to better adapt to their environment compared with other members of their species will be more likely to survive, reproduce, and pass more of their genes on to the next generation.

How is DNA used as evidence for evolution?

Organisms that seem fairly similar on the basis of comparative anatomy, show more genes in common than organisms that aren’t much alike. For example, 96% of the genes in humans and chimpanzees are identical. That two species and their common ancestor have similar DNA is strong evidence supporting evolution.

Which statement explains how the fossil record supports the theory of evolution?

Terms in this set (10) Which best describes how the fossil record supports the theory of evolution? The fossil record reveals intermediates that link different species.

Which statement best describes evolution in population?

Which of the following best describes evolution? It is the change in heritable traits in living populations over successive generations.

Which of the following statements best represent the role of mutations in natural selection?

Which of the following statements best represent the role of mutations in natural selection? Mutations fuel natural selection through the introduction of variable genes capable of being passed to new generations through reproduction.

Which of the following statements best describes how the process of natural selection led to this adaptation?

Which of the following statements best describes how the process of natural selection works? Better-adapted individuals will leave behind more offspring to carry on their genes, producing a dynamic “fit” between a population and its changing environment. … Gene flow causes the frequency of the brown allele to increase.

What does population genetics study?

Population genetics is the study of the genetic composition of populations, including distributions and changes in genotype and phenotype frequency in response to the processes of natural selection, genetic drift, mutation and gene flow.

Which statement best explains how the theory of evolution is supported by comparative embryology?

This supports evolutionary theory because comparative embryology is the act of comparing embryos. Scientists have compared the embryos of many species to show the relationship between the species. The embryos had backbone in common and also had a similar shape.

Which statement best shows the relationship of the concepts of evolution and natural selection?

Which best describes the relationship between evolution and natural selection? Natural selection leads to evolution.
