What structures help us determine evolutionary relationships between species? Explain.

Answers

Answer 1

Answer:

Homologous genes

Biologists often compare the sequences of related genes found in different species (often called homologous or orthologous genes) to figure out how those species are evolutionarily related to one another.

Hope this helped :]

Answer 2

Answer:

Homologous Genes

Explanation:

Homologous structures provide evidence for common ancestry, while analogous structures show that similar selective pressures can produce similar adaptations (beneficial features). Similarities and differences among biological molecules (e.g., in the DNA sequence of genes) can be used to determine species' relatedness.

by peristalsis, the wave-like motion of special muscles
by swallowing

Answers

Answer: Los alimentos son transportados a través del tracto gastrointestinal mediante un proceso llamado peristalsis. Los órganos grandes y huecos del tracto gastrointestinal contienen una capa muscular que permite que sus paredes se muevan.


Explanation:

Food moves through the digestive tract by using the process of Peristalsis which is a involuntary constriction and relaxation of the muscles of the intestine or another canal, creating wave-like movements that push the contents of the canal forward.

I can suggest some arguments for the Animal Population Control Debate that you can search for on .gov or .edu websites:

- Controlling animal populations is necessary to prevent overgrazing and damage to natural habitats. (e.g. "Wildlife Population Management," U.S. Fish and Wildlife Service, 2021)
- Animal population control can help reduce the spread of diseases between animals and from animals to humans. (e.g. "Zoonoses," Centers for Disease Control and Prevention, 2021)
- Overpopulation of certain animals can lead to an increase in human-wildlife conflicts, such as property damage and attacks on humans. (e.g. "Managing Human-Wildlife Conflicts," University of California Agriculture and Natural Resources, 2021)
- Population control can help prevent endangered species from going extinct by managing the populations of predators or invasive species that threaten their survival. (e.g. "Endangered Species," U.S. Fish and Wildlife Service, 2021)
- Effective population control methods, such as spaying and neutering, can help reduce the number of animals that are euthanized in shelters due to overpopulation. (e.g. "The Benefits of Spaying and Neutering," American Veterinary Medical Association, 2021)

Remember to always cite your sources and provide the necessary information for each argument, and I hope this helped :).

Tigers and Goldfish are not related.

FACT

Evidence #1

Evidence #2

Answers

Answer:

Yea

Explanation:

The relation between the tiger and the goldfish is that they are both animals that fall into the category of vertebrates. This means that both creatures have spines, and internal bone structure. This is a trait that distinguishes them from the invertebrates that have no spine and bone structure, like the octopus for example, or from the creatures that have an exoskeleton, which means they have a bone structure that is covering the body, but not inside the body itself, like the scorpions for example.
