Answer:
A vaccine works by training the immune system to recognize and combat pathogens, either viruses or bacteria. To do this, certain molecules from the pathogen must be introduced into the body to trigger an immune response.
Explanation: Hope this helped!
Answer:
A vaccine works by training the immune system to recognize and fight against the disease or virus. they do this by using specific cells or molecules from that said disease or virus, that way it triggers your immune system and it learns how to fight against it safely.

13. The diagrams show steps of a cell process.
What is the name of the process shown in the diagram? (The letters are for identification but do not
indicate the order of the process.)
Answer:
It's mitosis. Notice how the daughter cells have the same number of chromosomes as the parent cell. This does not happen in meiosis where the daughter cells after the first division will have half of the starting chromosomal set
The name of the process that is shown in the diagram is known as Mitosis. This is because the daughter cell holds the exact amount of genetic content as compared to the parental cell.
What is Cell division?Cell division may be defined as a type of biological process through which a parent cell divides into two or more daughter cells. It takes place as part of a larger cell cycle in which the cell grows and replicates its chromosome before dividing.
There are two types of cell division that may normally exist. They are mitosis and meiosis. Mitosis involves the formation of two daughter cells from a parental cell that contains the same amount of genetic content.
While meiosis involves the formation of four daughter cells from a parental cell that contains half the amount of genetic content as compared to the parental cell.
Therefore, mitosis is the name of the process that is shown in the diagram.

Fossils can usually be found in layers of
chronological order
radioactive dating
common ancestry
sedimentary rock
fossil record
metamorphic rock
nitrogen dating
timeline
Answer:
Sedimentary rock
Explanation:
All fossils are sedimentary rock. When an organism dies, layers of sediments pile on top of the organism, the sediments harden to become sedimentary rock. And for this reason, fossils cannot be igneous or metamorphic rock.

which structure is found in the cytoplasm of a prokaryotic cell
Answer:
By definition, prokaryotes lack a membrane-bound nucleus to hold their chromosomes. Instead, the chromosome of a prokaryote is found in a part of the cytoplasm called a nucleoid. Prokaryotes generally have a single circular chromosome that occupies a region of the cytoplasm called a nucleoid.

Describe the data used by Watson and Crick to determine the structure of DNA
they used Franklin's x-ray picture and data as well as other mathematical data to determine the specific structure of the DNA double helix. Compare and Contrast the structure of prokaryotic and eukaryotic chromosomes.
Data of X Ray diffraction is used by Watson and Crick to determine the structure of DNA.
What is X Ray diffraction?"X-ray diffraction is a phenomenon in which the atoms of a crystal, by virtue of their uniform spacing, cause an interference pattern of the waves present in an incident beam of X rays."This is used for determining the 3D structures of crystal.By using data of this method Watson and Crick gives helical structure of DNA.
Hence, the data used is of X Ray diffraction.

Does the DNA support the hypothesis that the coelacanth is the closest living relative to amphibians, such as frogs? If it does, explain how. If it does not, provide an alternative hypothesis suggested by the DNA data.
Answer:
DNA does not support the hypothesis that coelacanth is the closest relative to amphibians.
Explanation:
After several DNA analyzes, including analysis of mitochondrial DNA sequences, scientists found that coelacanth DNA does not support the idea that it is the closest relative of amphibians. However, other molecular analyzes, looking at the DNA of other living beings, concluded that the pulmonary fish is, in fact, the closest relative of the amphibians, with Coelacanth being the closest relative of the tetrapods.

Important features of the environment corridor
Answer:
Environmental corridors are areas in the landscape that contain and connect natural areas, open space, and scenic or other resources. They often lie along streams, rivers, or other natural features. These corridors protect environmentally sensitive areas by providing linkages in the landscape and potential buffers between natural and/or human communities.
Environmental corridors are complex ecosystems that provide an avenue for wildlife movement, protection of natural resources, and green space buffers for humans. These “lifelines for living” help support human, wildlife, and natural resource “communities.” The aerial photograph in Figure 1 will help you visualize a corridor and understand its function. Note the intertwining ribbons of natural areas winding across the landscape and through fields and towns.
