Assuming you mean why are some animals brightly colored:
There are multiple reasons animals are brightly colored. Probably the top two reasons are:
- To attract a mate, by showing they're ready for sex.
- To warn others they are ready and equipped to defend themselves.
- Etc.

An organism that will die in the presence of oxygen is called a?
anaerobe
How microbes are classified based on their oxygen preferences?
On the basis of oxygen requirement microorganisms are classified asAerobes: organisms that use molecular oxygen as electron acceptor.Anaerobes: organisms that use some molecule other than molecular oxygen as electron acceptor.Facultative organisms : organisms that can use either molecular oxygen or some other chemical compound as electron acceptor.
What kind of organisms are classified by the presence or absence of vascular tissue?
invertebrates
What are three things biologist consider when they classify an organism?
16s rRNA environment it lives in presence of a nucleus
What are alleles that have an effect on an organisms phenotype?
The presence of more than two alleles for a trait is known as probility. There might be one which is dormant and the others which are recessive.
Are mammals aerobic organisms?
Yes. An aerobic organism is an organism that can grow and survive in the presence of oxygen. Mammals need oxygen to have cellular respiration, so they are obligate aerobes.
What is biomagnetism in animals?
Biomagnetism is defined as the interaction of living organisms with magnetic fields. It can also be defined as the ability of a living organism to attract other living organisms with its presence.
What does the presence of similar DNA sequence in the genes in very dissimilar organisms imply?
It implies that the organism shares a common ancestor.
What does the presence of similar DNA sequences in the genes in very dissimilar organisms imply?
It implies that the organism shares a common ancestor.
What is the main different between organisms that share many characteristics and organism that do not?
The more derived characteristics organisms share,the greater their degree a kinship. For instance,a derived characteristic in plants is the presence of the vascular tissue.Although all organisms share similar traits.
What is a aerobic heterotroph?
An organism is said to be aerobic if it can only exist in the presence of free oxygen. Heterotrophs are organisms that do not produce their own food. Therefore, aerobic heterotrophs are organisms that cannot live without free oxygen and do not produce their own food.
Why might several different types of biologist be interested in the same organism?
Several different types of biologists might be interested in the same organism because all living things are connected. This means that biologists can tell things about other organisms and the environment through one organism.
An organism that will die in the presence of oxygen is called a?
anaerobe
How can a mycoplasma be recognized?
Mycoplasma organisms do not contain a cell wall. Thus, traditional cell staining techniques (which require the presence of a cell wall), do not highlight the organism. A special staining technique is required for visualization.
What does the presence of mitochondria in each cell suggest about multicellular organisms?
It is believed that mitochondria, which have their own independent genetics, became part of cells originally as a symbiotic organism. The fact that they are found in all cells of multi-cellular organisms is a tribute to the usefulness of mitochondria. It may well be that multi-cellular organisms would be impossible without them.
What was the first living thing that could see?
The oldest recorded organism that had photosensitive sensory organs with the ability to detect the presence and direction of light within a few degrees of accuracy was a prehistoric sea snail that existed approximately 550 million years ago. Organisms that could detect the presence but not the direction of light probably evolved earlier, but no fossils of these organisms have been found.
How is cell evidence for evolution?
the presence of organelles like the lysosome and the mitochondrion which both have double membranes. this suggests that these organelles were once free-living organisms that were incorporated into a larger organism in what could be called a mutual symbiosis.
