How many different species of guppies are there?
The Guppy is a single species. There are many variations (varieties) that have been developed by breeders but they are all the same species and can interbreed.
What are the organisms that produce more offspring than their environment can support and that they compete with one another to survive?
These are known as r-selected species. They typically have high reproductive rates, produce many offspring, and have low parental investment. They rely on high population growth to offset high mortality rates and competition for limited resources.
What evolution that involves changes in a species over time to produce adaptations that allow the organism to better survive its environment is?
The evolution that involves changes in a species over time to produce adaptations that allow the organism to better survive its environment is called natural selection. This process acts on heritable traits, favoring those that provide a survival or reproductive advantage, leading to the gradual improvement of the species' fitness in its environment.
What is the main purpose of reproduction?
The main purpose of reproduction is to ensure the survival of a species by producing offspring that inherit genetic traits from their parents. Reproduction allows for genetic diversity and adaptation to changes in the environment, ultimately helping to perpetuate the species.
How does hybridization happen?
Hybridization is a breeding technique where individuals from two different species or varieties are crossed to produce offspring with desirable traits. This can happen naturally in the wild or be carried out deliberately by breeders. The goal is to combine the genetic characteristics of both parent organisms to create a hybrid that exhibits the desired traits.
What group of organisms that can breed and produce fertile offspring?
A group of organisms that can mate and produce offspring which can themselves mate is called a species.
What do fossils reveal about changes in species over time?
The changes in different species penis sizes.
Is it true that to maintain the desired characteristics of a line of organisms breeders often use hybridization?
Yes, breeders often use hybridization to maintain the desired characteristics of a line of organisms. By crossing two different varieties or species, breeders can combine desirable traits from each parent to create offspring with the desired characteristics. This allows breeders to improve traits such as yield, disease resistance, or appearance in the population.
Are poison dart frogs illegal in Indiana?
No they are not. Many zoos and local breeders care for a variety of species of Dart frogs.
When do you say that a creature has evolved so much that it is no longer the same species?
When a creature undergoes significant changes in its genetic makeup and physical characteristics that prevent it from successfully reproducing with individuals of its ancestral population, it can be considered a different species. Reproductive isolation is a fundamental principle in defining species, meaning that if two populations can no longer interbreed and produce fertile offspring, they are considered separate species.
What evidence support evolutionary theory?
Fossils depict gradual changes in species over geologic time. This was one primary bit of evidence for Darwin's theory. Another was the similarity in species separated by geography. Race circles are one example of this. Variations introduced by pigeon breeders demonstrated that variations resulted in inheritable traits. Today we also have DNA, which clearly demonstrates common ancestry between species.
What is the purpose of the research paper on climate change and its impact on biodiversity?
The purpose of the research paper on climate change and its impact on biodiversity is to investigate and understand how changes in the climate are affecting the variety and abundance of plant and animal species in different ecosystems.
