Answer: Electrons jump from you to the handle.
Explanation: By walking on carpet, friction causes the rubber in your shoes to pick up electrons and then when you touch a metal doorknob you will feel a shock as the <u>electrons jump from your body into the doorknob.</u>
Answer:
3:1
Explanation:
Let the allele for tall plant be T; &
The allele for short plant be t
When Mendel crossed true-breeding tall pea plants(i.e TT) with true-breeding short pea plants(I.e tt); all the offspring were tall.
TT × tt
T T
t Tt Tt
t Tt Tt
we can deduce from the punnet square that the F1 offspring are all heterozygous tall plant.
Now, if the first generation (F1) tall plants are allowed to self-pollinate; we have a cross between Tt and Tt
TT × tt
T t
T TT Tt
t Tt tt
We can see phenotypically that we have 3 tall plant(TT,Tt, Tt) and 1 short plant(tt).
Therefore the ratio of phenotypes he expected in the F2 generation is (3:1)
The theory of Natural Selection was accepted after it got consensus from
scientists.
<h3>What is natural selection?</h3>
The theory of Natural selection defines the process in which individuals who adapts to their environment survives and reproduce more offspring.
- This theory was proposed by a scientist called Charles Darwin and Alfred Russel Wallace who also had the idea of evolution.
- This two scientist work together to publish a book on new evolutionary theory titled On the Origin of Species (1859). This is because they believed evolution occur through natural selection.
In this theory, organisms produce offspring but not all offspring survive this because they all struggle to live.
survival is based on survival of the fittest. some of those who survive can reproduce their kind while some do not grow to maturity and are loss.
Therefore, The theory of Natural Selection was accepted after it got consensus from scientists.

The correct answer is: behavioral isolation.
Behavioral isolation is a form of reproductive isolation (prevention of interbreeding in closely related but not the same species) based on behavior such as rituals and signals-song of birds. This means that two species of birds, Eastern and western meadowlarks
are capable for breeding but don't breed because of differences in their breeding calls-songs.
