What are Homologous Structures in Evolution?

1 answer:

5 0

Because they were passed down from a common ancestor, homologous structures are those found in related organisms that are comparable. These structures might or might not serve the same purpose in their offspring. The hands of various different mammals are depicted in the figure below. The basic skeletal structure of each is the same.

What is offsrping?

a person, animal, or plant's offspring or progeny is the result of reproduction. Parental transmission of the illness can affect children, a human or animal's direct offspring; a person born of parents gave birth to a lone child.

Creating offspring is considered reproduction. Reproduction comes in two basic forms: sexual reproduction and asexual reproduction. A sexually reproducing creature integrates the genetic material of both parents to create a genetically distinct individual. Asexual reproduction involves the self-replication of one parent to create genetically identical kids.

Into which chamber of the heart do the superior vena cava, inferior vena cava, and coronary sinus return deoxygenated blood? Cir

azamat

Answer:

Human heart is comprised of four regions, components, zones or muscular containers. As, the blood quality is regulated by the blood, by keeping the deoxygenated form of blood apart from the oxygenated form of blood inside the heart and then provide suffiecient amount of materials, solutes, and other nutrients to the different tissues and organs of the human body in a proper manner.

The deoxygenated form of blood is collected and brought to the right atrium by <u>the superior and inferior venacava</u>, as it provides a more safer route for the transportation of these materials in order to remove the unwanted substance from it by sending it back to the lungs through the pulmonary artery.

Inside the lungs the blood is cleaned up and then sent back to the heart in order to be pumped into the different portions of the heart.

In a particular woodland community, two species of rodents coexist: mice and chipmunks. Both species compete for the same kinds

scZoUnD [109]

Answer:

First, we take the owl out, the total number of mouse increases at a higher rate and the chipmunks are also decreasing in numbers. In an ideal ecosystem, both mice (lets call it "a") and chipmunks (lets call it "b") should increase since the restraining factor has been removed. But that is the opposite of what we should see. In that case, we will take the owl to be the "limiting factor" for the rodents.

The rodents will have free movement and exercise their fitness over the area, competition sets in between the two species. So we see, a flourishes while b dies out. This can be viewed most predictably that a has an overall greater fitness and would easily get resources and strive readily, which influences the survival rate for 2.

Hope you got something in any realm of understanding?
