Hi whats up, you wrote a statement not a question...
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:
football players or rugby players : endurance and strength training
basketball player or martial artists : muscular strength
rowers or triatheletes : endurance training
Explanation:
1. Football players or rugby players require to be physically active(stamina) and aerobically fit. This is because they have to play in the ground to cover long distances focusing on an object. This gives them tolerance and strength.
2. Muscle strength is important in basketball and martial arts because while gaining strength, speed, and endurance, you are also strengthening tendons and ligaments which will reduce the chances of injuries, such as sprains and tears.
3. Rowers or triathletes both are alternatives of racing that increase endurance training. Patience is key to cover a long distances on racing or running.
Answer:most protozoa (prevalently attached ciliates) can only graze on suspended bacteria and particles; in this way they have a significant effect on the effluent quality.
Explanation:Even though some protozoa (crawling ciliates and other forms) can eat flocculated bacteria, most protozoa (prevalently attached ciliates) can only graze on suspended bacteria and particles; in this way they have a significant effect on the effluent quality.
