Electric energy is the type of energy that a heated oven has cuz it uses electicity
Option D
polymerase chain reaction (PCR) do Makes more copies of a sample of DNA
<u>Explanation:</u>
A procedure to create several portraits of a distinct DNA section is termed as Polymerase chain reaction. In other words, it is a lab routine handled to compose various representations of a portion of DNA. PCR is extremely explicit and can be utilized to increase, or model, a particular DNA destination from a hybrid of DNA particles.
In PCR, the effect is regularly cycled within a range of temperature variations, which deduct countless models of the destination range to be exhibited. PCR intends to obtain sufficient of the objective DNA region that it can be examined or applied in some other way.
Answer:
Mechanical isolation
Explanation:
mechanical isolation is a form of prezygotic reproductive barrier, whereby similar species organisms become isolated and unable to successfully interbreed with each other to form zygote, as a result of incompatibility of their reproductive organ or structure, which prevents them from copulating. As a result of this, both species become separated as there is no gene flow between both.
The two species of juniper can be said to be kept separate by <em>mechanical isolation</em>, due to the differences and incompatibility of their reproductive structure.
The type of learning that the young sea otter used to be able to perform this task is social learning.
This means that the young otter learned what it is supposed to do from its surroundings - and what is surrounding it is its society of other otters. It is social learning because the otter didn't learn on its own that it needs to break open shells in order to eat what is inside, but rather it saw what the other otters were doing and thus learned it.
