You develop active immunity to a pathogen by

Active immunity can be natural or artificially developed. Naturally acquired - a person is exposed to a live pathogen, develops an immune response - and then creates memory T and B cells. Artificially acquired - a person is given a vaccine (which contains the antigen). This stimulates the same response, without the symptoms of the disease.

PLEASE HELP!!! ASAP 30 POINTS!! Why are the Galapagos Islands important in our understanding of how species adapt to their enviornment? Discuss it's geographic location, what Darwin concluded, and the research of the Grants.

Darwin’s research showed that finches beaks are different to fit their food source. It also started the theories of evolution and natural selection. The Grant’s research on the Galapagos Islands showed that evolution exists and can happen over a course of two years. They proved Darwin’s theories are true. Since all the plants and animals are native to the islands, they had to adapt to the new food source and climate. Beaks, size, etc. are all changes made to these organisms to be able to live on the islands. 

The Galapagos Islands are located in Ecuador and sit on the Pacific Ocean. The Galapagos Islands were formed from 3 million to 5 million years ago. Volcanic eruptions typically shield volcanoes formed the islands. They are located over a “particularly hot mantel” that causes volcanic activity. The outcome of many eruptions were islands because the left overs were pushed to the surface. The Galapagos islands are pretty big reaching an area of 3,093 miles. The temperatures range from 69 to 84 degrees creating a typically warm climate. 

Darwin studied medicine at age 16, but became fascinated specimens around the globe. He developed theories of natural selection and evolution. While he was on the Galapagos islands, he studied thirteen different species of finches.

 He observed finches and different beak structures. He observed their ability to consume foods such as nuts, bugs, and fruit. He concluded all were related to their beaks. For example, long, slender beaks are good to reach in the flowers of a cactus.

Charles concluded that the finches beaks are examples of adaptive radiation. To fit in the island, they had to adapt to the conditions. This lead to Charles’ theory of natural selection. 

Charles came to the conclusion of evolution and natural selection. Natural selection is the process where organisms adapt to their environment to survive and produce more offspring. Evolution is where different kinds of living organisms are thought to have developed. These theories have changed science forever and leave today’s scientists marveling of his theories.

I hope this helps:)

QUESTION POSTED AT 01/04/2020 - 01:38 PM

Discuss the process of the chloride shift in both the respiratory and the digestive systems.

  Carbon dioxide is generated in tissues as a byproduct of normal metabolism. It dissolves in blood plasma to form carbonic acid (H2CO3); red blood cell (RBC) carbonic anhydrase catalyzes this reaction. Carbonic acid then spontaneously dissociates to form bicarbonate (HCO3−) and a hydrogen ion (H+). In response to the decrease in intracellular pCO2, more CO2 passively diffuses into the cell.

Cell membranes are generally impermeable to charged ions (i.e. H+, HCO3− ) but RBCs are able to exchange bicarbonate for chloride using the anion exchanger protein Band 3. Thus, the rise in intracellular bicarbonate leads to bicarbonate export and chloride intake. The term "chloride shift" refers to this exchange. Consequently, chloride concentration is lower in systemic venous blood than in systemic arterial blood: high venous pCO2 leads to bicarbonate production in RBCs, which then leaves the RBC in exchange for chloride coming in.[2]

Describe how hibernation has helped bear species survive. Compare the needs of the organisms to the traits.

It's helps them survive throughout winter and thrive without food during winter too. Before they go into hibernation they consume a large amount of food which helps their heartbeat slow down. Other animals that don't hibernate have their source of food during the winter too, which is the reason why they don't hibernate.

1. How do your skeleton and muscular system work together, 2. What type of muscle tissue would you find in the heart? blood vessels? toes?

The answer to your first question involves a connection between your actions and your brain. Your bones and muscles work together through a series of impulses and signals communicated between the brain and skeletal muscles. In order to move, the nervous system then sends signals a skeletal muscle to contract. When the muscle contracts, this movement causes the attached bone to follow.

And as for your second question, 
The muscle tissue in your heart is cardiac, the muscle tissue in your blood vessels is smooth, and the muscle tissue in your toes is skeletal. 

I hope this helps you, have a nice day!
