Charles Darwin developed the idea of natural selection after a five-year voyage to study plants, animals, and fossils in South America and on islands in the Pacific. In 1859, he brought the idea of natural selection to the attention of the world in his best-selling book, On the Origin of Species.
Answer:
Humans get the energy and matter they need to survive from the food they eat. The foods humans eat contain carbohydrates, vitamins, and protein. All of those components are broken down by the human body with the aid of digestion.
A heterogeneous mixture composes of non- uniform components, so the concrete would be the answer, because you can tell the components from one another.
Answer:
S82.202A, S82.402A
Explanation:
X-rays are high frequency electromagnetic radiation, produced from the collision of electron beams with metals. This radiation cannot be perceived by the human eye as it is beyond the maximum frequency distinguished by human vision. It is important in medicine because it makes it possible to generate diagnoses through images. The capture of these images correspond to codes that are placed on the x-ray machine and correspond to a specific part of the body, the codes that correspond to the tibia and fibula are S82.202A and S82.402A.
Answer:
As a fertilized egg divides, the cells differentiate because they have to become [different] specialized cells to perform different functions.
Explanation:
The molecules of DNA of a human have to be duplicated over end over so that every human’s cell contains a copy of DNA that can be found in a fertilized egg.
When cell differentiates, the embryonic cell becomes a specialized cell. This leads to an expression of gens and that is what dictates the functioning of one cell.
