The major source of variation among organisms is genetic variation, which arises from mutations, gene flow, and sexual reproduction. Mutations introduce new genetic material, while gene flow allows for the exchange of genes between populations. Sexual reproduction combines the genetic material of two parents, leading to unique combinations of traits in offspring. Together, these processes contribute to the diversity of traits observed in populations, enabling adaptation and evolution.

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.
Is there any division of labor among cells of a colony?
No, There is no division of Labour among the cells of a colony.
What terms are the names of domains in classifying organisms?
The names of domains in classifying organisms are Bacteria, Archaea, and Eukarya. Bacteria and Archaea consist of prokaryotic organisms, which lack a nucleus, while Eukarya includes all eukaryotic organisms, characterized by cells with a nucleus. This classification reflects major differences in genetics, biochemistry, and cellular structure among these groups.
Which hexose is also known as dextrose?
Dextrose is another name for the hexose sugar glucose. It is commonly found in nature as a major energy source for living organisms and is often used in the food industry as a sweetener and energy source.

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.
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 organisms does not rely on krill as a major food source?
Leopard Seal
What are the three major interactions among organisms in an eco system?
Grow,respond to the environment,and reproduce
What is a major struggle among organisms to obtain the resources that they need to survive?
Competition for limited resources, such as food, shelter, and mates, is a major struggle among organisms. This competition can drive evolutionary adaptations and behaviors that help individuals improve their chances of resource acquisition and ultimately survival.
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.
2 facts about nuclear energy?
Nuclear power is the major source of energy among all nations.
What are the four major points of the theory of natural selection?
1. Overproduction - more offspring are born than survive 2. Genetic Variation - there is variation in the population 3. Struggle to Survive - organisms with suitable variations will survive and reproduce 4. Differential Reproduction - suitable variations are passed on to offspring
Which atmosphere gas is photosynthesis the major source of?
Oxygen is the major source of photosynthesis in the atmosphere. During photosynthesis, plants and other photosynthetic organisms convert carbon dioxide into oxygen through the process of photosynthesis. This oxygen is then released into the air, replenishing the levels in the atmosphere.
