You are in a canoe going downstream (with the current). If the current is traveling 5mi/hr, and you are rowing 12 mi/hr, what is

Simora [160]3 years ago
6 0

Answer:

The velocity of the canoe is 7 mi/hr.

Explanation:

Given that,

Speed of current, v_c=5\ mi/h

Speed of the person, v_p=12\ mi/h

We need to find the velocity of the canoe. Here, the person is going downstream with the current. So, the velocity of canoe is given by :

v=v_p-v_c\\\\v=12-5\\\\v=7\ mi/hr

So, the velocity of the canoe is 7 mi/hr. Hence, this is the required solution.

Brown mice disappear from the mouse population for two generations and then reappear in the third generation. Give two possible
gizmo_the_mogwai [7]

Answer:

The trait is inherited in the homozygous recessive pattern

Possible mating is between two heterozygous individuals

Explanation:

One possible explanation for this is that the trait for this brown mice has to inherited in the homozygous recessive condition. It is possible for this trait to skip two generations and then reappear if it has to be inherited in the homozygous recessive condition.

Another explanation to complement the first is that for this trait to reappear, there was mating between two heterozygous individuals (with one allele being domiant and the other being recessive). It is possible that all matings within the two skipped generations was between an heterozygous and a homozygous dominant or between two homozygous dominant individuals which will not produce the brown mice..

Which situation would not encourage competition?
torisob [31]

A long, wet season results in additional earthworms in a robin habitat.

Explanation:

A long, wet season resulting in additional earthworms in a robin habitat will not lead to competition in an ecosystem or area.

Competition between organisms is the struggle for limited resources in the environment that are beneficial to all lives.

  • Competition is usually driven by shortages and lack of resources to make life better in the ecosystem.
  • When resources becomes depleted and are in limited amount organisms will begin to strive among on another to develop advantages that would make them top out.
  • A long, wet season resulting in the introduction of additional earthworms in a robin habitat is not an example of competition.
  • The earthworms available is a limiting factor and this has been circumvented by the introduction of more earthworms during the prolonged wet season.
