Fossils of canines were found on opposite sides of a mountain range. The fossils are from species that are anatomically similar, but the climates were extremely different on each side of the range. Which type of evidence for evolution do these fossils exemplify?
A. vestigial structures
B. analogous structures
C. coevolution
D. biogeography
Answers
The phenomenon described in the question is an example of coevolution.
What is coevolution?Evolution refers to the changes that occur in organisms as they metamorphose from one form to another over a given time interval. The changes that occur in one specie usually affects the changes that occur in related species. This is known as coevolution.
Hence, if fossils of canines were found on opposite sides of a mountain range and they belong to species that are anatomically similar, but the climates were extremely different on each side of the range, it is an example of coevolution.

In cystic fibrosis, an important protein destined for the plasma membrane never makes it beyond the Golgi complex. This protein is necessary for Na and Cl- transport and is critical for maintaining mucous secretions of the appropriate consistency. Devise an explanation for why this may occur.
Answers
Answer:
The correct answer is - Golgi apparatus marks or tags on this protein as incorrect or dysfunctional tags which then prevents it from transported to the membrane.
Explanation:
The role of the Golgi apparatus is to process and package the proteins produced and come from ER and transfer them to the plasma membrane in order to transfer them to their target sites.
The Golgi apparatus marks or tags the proteins that are incorrect or dysfunctional, in order to prevent these proteins from transporting to the plasma membrane and harm the membrane. In CF, the case is similar as the Golgi apparatus tags these proteins as incorrect or dysfunctional.

Splicing of exons and exclusion of introns
-mRNA that is transcribed from DNA usually has large regions of genetic code that just do not code for anything. This is a pretty conserved phenomenon among eukaryotes, to have meaningless sequences of DNA (introns) separating the meaningful sequences of DNA (exons). Introns must be spliced out of mRNA so that its translation leads to a functional protein.

A museum curator collects fossils from two different periods. He has 400 from one period and 204 from a later period. He plans to arrange the fossils in display cases so that each case contains the same number of fossils. Also, each case must contain fossils from only one period. What is the largest number of fossils that can be placed in each case
Answers
Answer:
4
Explanation:
Number of fossils collected over period 1:
400
Number of fossils collected at a later period :
204
For each display case to have the same number of fossils ; the greatest number of fossils possible per case:
Obtain the greatest common factor of both 400 and 204
400 = 1, 2, 4, 5, 8, 10, 25, 40, 50, 80, 100, 200, 400
204 = 1, 2, 3, 4, 6, 12, 17, 34, 51, 102
Hence, the greatest common factor (400 and 204) is 4
Hence, the greatest Number of Fossil possible per case = 4

A. Gametes always form with genetic material identical to the parent
B.Gametes are formed with the same number of chromosomes as the parent cells
C.Offspring display half of their traits from their mother and half of their traits from their father
D.Offspring have traits not displayed by either parent
Answers
Answer:
c option is correct.
Explanation:
gametes are produced by meiosis during which genes get crossed in a process of crossing over ad new recombinent characters are produces. these gametes fertilized and offsprigs have multiple characters they get from their mother and faaher. so offsprimgs have characters half from mother and other half from father.
Genes often produce gametes. The statement that describes a possible result of this process is that Offspring display half of their traits from their mother and half of their traits from their father.
What is genes and gametes?A gene is known to be the molecular unit of heredity of all living beings.

walrus often dive for 5 to 8 minutes suggest why having over three times as many red blood cell as humans help them perform this function
Answers
They give birth to live offspring, have hair or fur on their bodies, and possess mammary glands that produce milk for their young. They breath air with lungs and have ears that stick out instead of the earholes, such as what reptiles and birds have.
Walrus often dive for 5 to 8 minutes because their red blood cells (that carry the oxygen) are exceptionally large. In addition, they have lots of myoglobin in their muscles that can store oxygen.
Why do Walrus have high blood circulation?The walrus can remain under the surface of the water for up to 10 minutes. They will usually surface every 5 to 8 minutes to get air and stay at the surface for about 1 minute. They will stay in the shallow waters, no more than 262 feet below the surface.When they dive the blood flow is cut off from their skin, extremities, and stomach. All of these adaptations allow for efficient and lengthy use of oxygen stores. They have a larger percentage of blood in their bodies to carry oxygen, about 12 percent of their weight as compared to only 7 percent for humans.To learn more about Walrus, refer to:https://brainly.com/question/25164635

The stem cell therapy helped lucy break down deoxyadenosine as it helped her fight off the stop protein, eventually helping her create more amino acids.
What is amino acid?Amino acid has the organic compound containing both an amino[tex](-NH2)[/tex] and a carboxylic acid [tex](-COOH)[/tex] functional group. The component of amino acid not contained in starch is that amino acids contain nitrogen but not starch.
On the other hand, starch has a carbohydrate molecule made up of monomers called monosaccharides. The monosaccharide is a long chain of carbon, hydrogen and oxygen atoms. This suggests that the major structural difference between amino acids and starch has that amino acids contain nitrogen but not starch.
There are several types of protein such as structural protein, transport proteins, antibodies, contractile proteins, hormonal proteins, and enzymes.

Answers
Answer:
D
Explanation:
because wind is depositing sand to build
Wind depositing sand to build up sand dunes best illustrates a natural process acting as a constructive force. Therefore, the correct option is D.
What is a constructive force?Constructive forces are the forces that are responsible for the formation of new landforms on the surface of the earth, such as deposition, earthquake, volcanoes etc.
Wind depositing sand to build up sand dunes is the natural process depicting the constructive force because sand dunes are formed by constructive forces that add sediment to an area, in this case, wind depositing sand.
Option A is incorrect because river erosion is a destructive force that wears away soil and rock, rather than building it up. Option B and option C are also destructive forces. Therefore, the correct option is D.
