Answer:
The correct answer is b. actors have to be more likely to carry the altruistic allele than non actors.
Explanation:
Altruism is the behavior by an organism that benefits other organisms by costing its own fitness. The actor is the individual who is doing altruism and the recipient is the individual who is getting benefited by the actor's altruism.
An example of altruistic behavior can be seen in animal kingdom easily. Vampire bats give blood to those members of the community who were not able to go for search for blood show altruistic behavior.
Actors have altruistic genes that suggest them to behave altruistically. Non-actors may not contain alleles of altruism but the recipient might have altruistic alleles.
Hamilton's rule says that natural selection will favor the altruistic allele when rb > c.
where r = coefficient of relatedness between donor and recipient
b = benefit received by recipient and
c = cost paid by altruist.
Therefore, the correct answer is b.
Answer:
Genetic diversity: Some individuals in a population of wild rabbits are resistant to a new disease.
Ecosystem diversity: If the population of wild rabbits decreases, a bobcat can switch its diet to squirrels or woodchucks.
Species diversity: Populations of wild rabbits from a forest and from a neighboring meadow can interbreed, which increases variation.
Biodiversity of an ecosystem is usually explored by three diversities which are responsible for ecosystem stability they are : genetic diversity, ecosystem diversity and species diversity.
Genetic diversity is the variety of genes within a population of species. Each species consists of individuals bearing different genetic composition. Some individuals in a population of wild rabbits are resistant to a new disease because they exhibit genetic diversity within the population as a consequence some individuals exhibit genes which protect them against new disease.
Species diversity is the variety of species within an ecosystem. Populations of wild rabbits from a forest and from a neighboring meadow can interbreed, which increases variation is an example of species diversity. The wild rabbits from a forest and a neighboring meadow are two species living in an ecosystem stating the diversity of species in an ecosystem.
Ecosystem diversity is the variety of ecosystems in a given region.If the population of wild rabbits decreases, a bobcat can switch its diet to squirrels or woodchucks is an example of ecosystem diversity because in an ecosystem there is interaction of organisms as predator prey relationship. This example is also relating with predator prey relationships in an ecosystem.
Chlorophyll is the source of carbon in the sugar molecule
Some afferent neurons are sec specialized to detect stimuli, whereas efferent neurons send signals to the effectors of the nervous system.
If they remain isolated for a long period of time, the two groups will probably diverge genetically, and may result in speciation.
Genetic divergence is the process whereby two groups of the same ancestral species acquire autonomous genetic changes through time, usually after the groups have been separated reproductively for some period of time.
Speciation is an evolutionary process whereby populations develop to become different species.
