What characterisics could be used to classify animals into different groups?
Scientists classify animals into two large groups based on wether the animal has a backbone or not. shtytrsywsysys
Why do scientist think related species have similar body structures and development patterns?
Why do scientists think related species have similar body structures and development patterns?
Why do people try to group living things?
There are a lots of things in our universe. To be able to study them, we need someway to group or classify them together. Initially scientists divided all things into living vs. non-living, then subdivided those (i.e. animal kindom and plant kingdom, then continued dividing them on how the items were seimilar or dissimilar (phlyum, genus, species). While this worked for centuries, genetic testing is causing some divisions to be be reconsidered.
Explain how the formation of fossils provides a chronological record of past life forms?
The fossil record provides scientists with a time lapsed view of plant and animal life. Scientists are then able to use carbon dating and scientific inquiry to determine when each type of plant and animal species lived.
How do scientists learn about extinct species?
Just think about this : Imagine scientists studying plants and animals of the past WITHOUT fossils. The slightest clue found on fossils leads scientists towards a conclusion that would be impossible to get without a mineralized remains of a dead organism, that we call fossils. The most important factor is the visualization of that animal or plant's shape. The foot's shape, number of bones, of a fossiled animal may give to scientists a clue on how that extinct animal could run away from predators and so on. The slightest evidence is important to reach on a conclusion when a fossil is being studied, which would be impossible without them. In other words, fossils are the linkage with the pass
What are similarities for animal species in Antarctica?
they have furry skin..
Why did scientists make up a classification for animals?
beginning in ancient times, scientists tried to develop a system of classifying animal and plants. The system we use today was developed by the Swedish naturalist Carolus Linnaeus (1707-1778), who separated animals and plants according to certain physical similarities and gave identifying names to each species. basically to identify every plant and animal species.
how many animal species are in the world?
There are approximately 1.2 million known species of animals, but scientists estimate there are closer to 8.7 million animal species on earth.
What is observing a species in a controlled environment?
to study animals in a controlled place. where the person studying the animal has controll of the environment... like in a zoo
How can learning about one animal help scientists learn about other animals?
because one animal may look the same so the 1st 1 might have a few similarities
Who decides if an animal belongs to a new species?
If the species is scientifically proven to be new or undiscovered, then the person who discovered it gains the right to name the new species. The scientists who study the species decide to add it to the new species list.
What are similarities of plant and animal hormones?
Animal and plant hormones play an important role in the growth and development of the species. They work by the existence of specific pathways, and complex signal transduction.
Most direAn exoskeleton functions in the same way as a hydrostatic skeletont evidence of evolutionary relationships between animal species comes from comparing?
their anatomical structures and genetic sequences. By studying these similarities and differences, scientists can infer how closely related different species are and how they have evolved over time. This evidence helps to trace the evolutionary history of different animal groups and understand how they are all connected through a common ancestor.
Is a gorilla an animal?
yes , it is a type of species and it is a mammal , many beleive humans were enventd from the species of gorrillas as us humans have similarities with these animals
What do biologists use to classify animal's?
Biology may use skeletal similarities in determining where extinct animals are placed in relation to surviving species and other extinct species. Chromosomal similarities, whether they are eukaryotes (animals, plants, fungi), or whether they are prokaryotes (bacteria, archaea) are commonly used to classify modern species. Species that are believed to have a similar ancestor are grouped into genuses.
Is there any animal that can survive in vents and reproduce without food?
There are no animals discovered fully, but some people and scientists have agreed there is 5 species of animal are able to everyone if these.
What does it mean if a company is observing moratorium when it comes to animal testing?
It is a great thing if a company is observing a moratorium on animal testing. This means that they are not testing on animals.
