How is it possible that phylogenies based on sequences from nuclear genomes and organellar genomes (i.e., chloroplasts and mitoc

hondria) from the same group of species yield phylogenetic trees with different branching orders? the genome of the endosymbiont is more closely related to members of the group in which it originally evolved, while the nuclear genome of the engulfing organism has its own evolutionary trajectory.for organelles like chloroplasts, no mutations can occur or photosynthesis would stop and the organism would die. the nuclear genome can accumulate mutations, so it can continue to evolve.nuclear and organellar genes evolved at different rates, obscuring evolutionary relationships.transfer of genetic material from the genome of the endosymbiont to the host results in two phylogenies, host and endosymbiont. the host genome continues to accumulate mutations, but the endosymbiont genome cannot?

Which statement correctly describes metabolic reactions? Intermediary metabolism breaks down material and transforms fuels into
DedPeter [7]

Answer:

Catabolic processes break down material and transforms fuels into cellular energy, whereas anabolic processes require energy for biosynthesis.

Explanation:

Metabolism is a constructive and destructive process which occurs in the body of living organisms. There are two types of metabolism i. e. catabolism and anabolism. Catabolism is a destructive process in which food molecules are broken down into simpler substances for the production of energy while anabolism used this energy for the formation of new cells and muscles etc.

The key to the evolution of altruism is that a. recipients have to be more likely to carry the altruistic allele than nonrecipie
cupoosta [38]

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.
