What else can I help you with?
True or false The loss of a species from an ecosystem usually has no effect because of the presence of other species in the ecosystem?
False. The loss of a species from an ecosystem can have cascading effects on other species and the overall balance of the ecosystem. Each species plays a specific role in the ecosystem, so the loss of one can disrupt the interconnected relationships within the system.
What is the Major cause for the seasonal temperature variation at any given latitude on earth?
The major cause for seasonal temperature variation at any given latitude on Earth is the tilt of the Earth's axis relative to its orbit around the sun. This tilt causes different areas to receive varying amounts of sunlight throughout the year, leading to changes in temperature.
What two different sources of genetic variation in a plant or animal population?
The main source of genetic variation is a large population with a large gene pool.
What does intermediate traits mean?
a measurable trait in which there is some evidence of the operation of a simple major cause, but in which the variation within the putative categories is such as to cause overlap and hence ambiguity in classification of any particular reading.
What is the major cause of depletion of biodiversity in India?
The major causes of depletion of biodiversity in India include habitat loss due to deforestation, urbanization, and agriculture expansion; overexploitation of natural resources such as hunting and fishing; pollution from industries and agriculture; and invasive species disrupting native ecosystems.
What is a major cause of variation within species?
Genetic variation, caused by mutations in DNA, is a major source of variation within species. Mutations can lead to differences in traits such as color, size, and behavior, allowing for natural selection to act upon these variations.
One of the major elements of natural selection is that all?
All species have genetic variation. ;D
What are the four major points of Darwin?
Species evolve over time through a process of natural selection. All species share a common ancestor. Variation exists within populations, leading to differential survival and reproduction. Evolution is driven by the accumulation of small, gradual changes over long periods of time.
True or false The loss of a species from an ecosystem usually has no effect because of the presence of other species in the ecosystem?
False. The loss of a species from an ecosystem can have cascading effects on other species and the overall balance of the ecosystem. Each species plays a specific role in the ecosystem, so the loss of one can disrupt the interconnected relationships within the system.
What could cause extinction of a species after a major environmental change?
Their bodies aren't adapted to the new environment yet.
Which major ideas did Charles Darwin introduce in his writings?
Charles Darwin introduced the theory of evolution through natural selection, which posits that species evolve over time due to the survival and reproduction of individuals with advantageous traits. He emphasized the importance of variation within species and the role of environmental pressures in shaping these traits. Additionally, Darwin's work highlighted the interconnectedness of life forms, suggesting that all species share a common ancestor. His seminal work, "On the Origin of Species," laid the foundation for modern evolutionary biology.
What is the Major cause for the seasonal temperature variation at any given latitude on earth?
The major cause for seasonal temperature variation at any given latitude on Earth is the tilt of the Earth's axis relative to its orbit around the sun. This tilt causes different areas to receive varying amounts of sunlight throughout the year, leading to changes in temperature.
Is genetic recombination a major source of variation among organisms?
Yes.
Why is sexual reproduction a source of genetic variations?
When alleles are recombined during sexual reproduction, they can produce dramatically different phenotypes. Thus, sexual reproduction is a major source of variation within many population.
What represents the major concepts of biological theory of evolution?
The major concepts of the biological theory of evolution include natural selection (survival of the fittest), genetic variation, adaptation, and descent with modification (common ancestry). These concepts explain how species change over time through the process of evolution.
What risk is there to as species that only reproduces by cloning?
A major risk to a species that only reproduces by cloning is lack of genetic diversity. This can make the species more vulnerable to diseases, environmental changes, and other threats, as they lack the genetic variation that can help populations adapt and survive. Additionally, if a clone is susceptible to a specific threat, it can wipe out an entire clone-based population.
What are two things a species name may do?
A species name may provide information on the scientific classification and relationship of an organism within the taxonomic hierarchy. It can also help in the identification and communication of a particular species, allowing scientists to have a standardized way of referring to and studying organisms.
