Answer:

all 20

Explanation:

It is impossible to know how many individuals will have the disease at the end without knowing other factors such as the condition where the subjects are being held, trial specifications and safety measures, etc. Based on the information provided, the best prediction that can be made is that all 20 subjects will have the disease. This is because since none of them are immune the disease will spread between the patients/subjects through contact or testing equipment.

Apple maggots are a type of fly native to North America. Prior to the introduction of the apple tree to North America, apple mag
scoundrel [369]

Answer:

B

Explanation:

B is the most likely consequence because of the following facts we are told:

  • After apple trees were introduced, some apple maggots began feeding from and laying their eggs on apple trees
  • Adult apple maggots will only mate on the type of tree on which they were born.

This provides a geographical isolation (because they are feeding and laying eggs on separate trees) and reproductive isolation (because they will only mate on the type of tree on which they are born).

These two factors increase the chances that apple maggots feeding on apple trees will only encounter those who have mated on the same tree, and continue to mate this way. Over time, the populations (i.e. apple tree vs hawthorn tree) will intermix less and less. This will mean the genetic pool will become distinct, and natural selection will be acting differently (different habitats and different genes), encouraging speciation.

How do adaptations help Ann organism to reduce competition for food and other resourses
Gre4nikov [31]
An organism adapting to its environment leads it to be more ‘equipped’ for survival.
Competition is when other species fight for the same resources that another species needs. Also, it would produce offspring with these adaptations.

An example (to help you better understand);

A blue jay has great eyesight, strong wings, and sharp beak. (Better adapted organism) Another blue jay has great eyesight, weak wings, and dull beak. (The competitor/unadapted)

Both birds find the same food source and are now competing for it. The first bird has sharp beams, which is better for breaking, and ‘chomping’ the seeds/food. The second bird would struggle to consume its food (seed) unless it’s worms.

So which one is better adapted? The first blue jay.

And i hope this helped show how competition can be reduced.
