Answer: Genes are segments of deoxyribonucleic acid (DNA) that contain the code for a specific protein that functions in one or more types of cells in the body. Chromosomes are structures within cells that contain a person's genes. Genes are contained in chromosomes, which are in the cell nucleus.

<em>The correct option here would be</em><em> D</em><em>.</em>
The endomembrane system refers to a group of membrane-based organelles whose primary function is to synergistically work together to modify, package, and transport lipids and proteins. The system includes organelles such as the lysosome, the nuclear envelope, the endoplasmic reticulum, and the Golgi apparatus.
For an endomembrane system function involving a protein, the protein would first of all need to be synthesized by the ribosome - the free ones or the ones attached to the rough endoplasmic reticulum. Thereafter, the synthesized protein would then be folded or packaged into transportable vesicles. The vesicles are then received by the Golgi apparatus which further modifies the proteins before transporting them accordingly.
Hence, the correct order of a typical endomembrane system function would be:
- <em>Ribosomes on the RER synthesize proteins.</em>
- <em>Proteins are packaged into transport vesicles.</em>
- <em>Golgi apparatus receives transport vesicles from the RER.</em>
- <em>Proteins are modified by the Golgi apparatus.</em>
- <em>Modified proteins may be secreted from the cell by exocytosis.</em>

An example of codominance would be when a red and white flower breed a pink flower.
Answer:
composition of meteorites
Explanation:
The continental drift theory has been based upon several evidence. The shape and perfect fit of South America and Africa is one of those evidence. The fossil records are another very strong evidence, as there are fossils of the same species on different continents that are not connected to each other in the present, and in nature is practically impossible to have the same species in different continents. The evidence about the climate also suggests that the continents have been moving, as there are remains of glaciers at places that nowadays are deserts and savannas. The meteorites are not one of the evidence though, and their composition doesn't have anything to offer in this tehory, as their composition is not related to the Earth and the processes on it.
