Answer:
Smaller muscle groups with a similar functional ability might include the antagonist major which acts as synergist in producing the same action as the agonist.
example : the biceps and triceps muscles of arm, work together as agonist and antagonist respectively.
The biceps helps to lift up or flexes the forearm and the triceps helps to extend it.
Explanation:
many muscles work together to make an action happen.
the muscle who is involved in an action principally, is known as prime mover or Agonist muscle.
Antagonist muscle does the opposite action of the agonist muscle.
antagonist also helps in-
- maintaining the body posture or position.
- controls the rapid movements.
like, to move a bone , the muscles attached to it work together to make a movement happen. like- to lift up a arm, agonist or prime mover muscles helps to lift up or flex the arm and the antagonist or synergist muscle helps to extend it.
Answer:
As population size approaches the carrying capacity of the environment, the intensity of density-dependent factors increases. For example, competition for resources, predation, and rates of infection increase with population density and can eventually limit population size.
Explanation:
Carrying capacity can be increased by the amount of food available, the local extinction of a competitor, an increase in species fertility, a decrease in predation, an increase in the amount of habitat available for use, and adaptations to the environment, such as resistance to disease or adaptations that serve to ...
He found sea fossils high on the mountain, evidence that continents and oceans had changed over time
Species at imminent risk of extinction are classified as endangered species.
Answer:
C. many mosquitoes today are descendants of mosquitoes with insecticide-resistant characteristics
Explanation:
When insecticides were first sold, they where highly effective in killing mosquitoes but few mosquitoes will definitely survived. If these mosquitoes that survived mate together, they will produce hybrid offspring that possess characteristics that are insecticide-resistant. The more insecticide-resistant mosquitoes that breed together in subsequent generations, the more permanent mutant hybrid offspring will be produced which will eventually make them to become resistant to the use of insecticides over them.
