Would it be possible to bring extinct species back? In an article it was expressed how brinng extinct species back is still very futuristic, and we should aim at a smaller creature. Using a smaller sized species like the Christmas rat can set up scientists for potentially larger species. There is a major issue that comes up and that is incomplete genes. It makes it difficult to even compare modern day rat to the Christmas rats' genome because their genes are specialized and as more time passes, the harder it is to have a match. The article also talked about using modern day elephants to make a woolly elephant, meaning they don't want a perfect match. Rather, scientists want to make hybrids since it could be more realistic.

Biogeography Which of the following is not thought to have been a source of organic molecules on early Earth? * Meteorites Radiation from the sun Cosmic dust Hot water near volcanoes A population of wildflowers consists of two flower colors. Yellow flowers (C^y) are completely dominant to white flowers (C^w). If the frequency of the C^y allele is 70%, what is the frequency of the C^w allele? * 70% 30%

I need help with a biology question Microevolution is defined as   all the answers are correct evolutionary changes on a grand scale new forms replacing old forms changes in gene frequencies that result in subtle changes in a population

You have found fossils of a new species of ape that walks upright. After 11 additional years in the field, you discover a fossil of what you think is the common ancestor of the new species of ape and all other gorillas. What types of data would give you the best information on the environment of this ancestral organism? anatomical features of the new species of ape fossils of plants and animals found with the fossilized common ancestor gene sequencing of the new species of ape anatomical features of the fossilized common ancestor behavior of the new species of ape

When a gene from one species is transferred into another species, the result is 1 -a GMO 2- new species 3 a hybrid animals 4- a lethal mutations 5- eugenics

. The Process of Evolution by Natural Selection – Be able to explain the process of evolution by natural selection as it applies to a specific living thing using the outline below: Natural variations caused by random mutations (adaptations) in DNA exist within populations. Those with helpful adaptations survive an environmental change (maybe a predator.) The survivors breed, passing on the inherited mutation (adaptation) to offspring. The resulting population has more of the successful inherited mutation (adaptation) than the original population. Phylogenetic Trees Infer evolutionary relationships of living things by interpreting phylogenetic trees. Know the divisions of hierarchical classification. (DKPCOFGS) c.  Differentiate between homologous and analogous (caused by convergent evolution) structures

Which of the following is unlikely to contribute to natural selection Mutations of the somatic cells Mutations of the reproductive cells Natural disaster Infectious disease in the population

Hox genes Group of answer choices a. are only found in nematodes and arthropods   b. are pseudogenes that occur only in fungal DNA   c. are one of the shared, derived characters that unify fungi and animals   d. are single genes that act as master switches that activate other genes, which ultimately forms an entire segment of an animal's body   e. are pseudogenes that occur only in animal DNA

18. What is an example of convergent evolution?  Conserved rRNA being found in all forms of life An RNA polymerase in bacteria and in humans A bird wing and a bat wing The use of chlorophyll in different plants for metabolism

When scientists use molecular clocks to estimate the timing of evolutionary change, the assumption is that... Group of answer choices telomeres were not fixed the climate was constant throughout the lineage the organisms engaged in random sexual mixing genes in related species mutate at a fairly constant rate 20
