Answer:
Emphysema can lead to destruction of the alveoli, the tiny air sacs that allow oxygen to get into the blood. Their destruction leads to the formation of large air pockets in the lung called bullae. These bullae do not exchange oxygen and carbon dioxide like normal lung tissue. Also, the bullae can become very large.

A vaccine is a substance that contains all or part of a noninfectious version of a disease-causing organism. When the vaccine is administered to a person, the person's immune system attacks the noninfectious version of the organism and learns to recognize its surface proteins. The next time the immune system comes in contact with the same surface proteins, it has a defense already prepared in order to respond quickly to the invading organism. In this way, a vaccine gives people immunity to the disease-causing organism.Vaccines can be life-saving, but there have been a few cases of people catching a disease from the administered vaccine.How might genetically engineered organisms solve this problem?
Answer:
GMOs can be used to produce cheaper, easier to administer, and safer vaccines
Explanation:
Genetically modified organisms (GMOs) are organisms whose genomes have been altered in the laboratory by using genome engineering techniques. These GMOs have a fundamental role in clinical research and they have been increasingly used in the last decades for developing safer and cheaper vaccines. For example, genetically engineered hepatitis B vaccines have been developed with recombinant DNA techniques using genetically modified yeast (Saccharomyces cerevisiae). Moreover, GMO plants are nowadays also being used to develop consumable vaccines which can be orally administered to be absorbed and assimilated through digestion.
An animal jaw that has small incisors and canines but wide premolars and molars may belong to a _____. a. beaver c. horse b. dolphin d. wolf
There is less need for canines and incisors in herbivorous animals as it is mainly used to tear the flesh. Herbivorous animals mainly have developed premolars and molars to grind the grass properly. Horse has small incisors and canines but wide premolars and molars.
What are the different types of teeth?Teeth are usually covered with a hard substance called enamel which helps them to be strong. Its color is slightly yellow.
Teeth are of four types. Namely:
Incisor: These are located at the front and are used to cut the food.Canine: These are at the sides of incisors and are generally used for tearing the flesh. pre-molars: These are present near the corner of the jaw before molars and are used to grind.Molars: these are at the corner of the jaw and are also used for grinding food.Canines are well developed in carnivorous animals as they need to tear the flesh. But in the case of herbivores, these are comparatively smaller.
Thus, an animal jaw that has small incisors and canines but wide premolars and molars may belong to a horse.

Which characteristic do all protists have?
They all make or consume food.
They all survive in any environment.
They are all unicellular.
They all have flagella.
Answer: They all survive in any environment.
Explanation: Protists have the ability to survive in any environment, even extreme environment. They can live in the ocean, desert or extremely hot environment, or even a extremely cold environment.
I'll explain why the others aren't correct.
Protists can be both unicellular and multicellular, they're not always unicellular. Kingdom Protista contains all eukaryotics, so they're not always unicelluar.
Protist cannot make or consume food. Animals consume food, and plants make food, not protista. Yes they're many plant-like protists out there, such as algae, they get their food from the sun above. So all protists cannot make or consume food.
Protist does have flagella, but not all protists. Protists that are motile and generate movement have flagella, meaning they move. Not all protist move, like plants can't move. So, not all protists have flagella, meaning they can move.
Let me know if you have any questions.

What is Endosymbiotic Theory ?
How does it explain Eukaryotic Cells?
What evidence do scientists have to support this theory ?
Based on the video of the amoeba sisters.
Answer:
1.States that organelles such as chloroplasts and mitochondria were once free-living prokaryotes which eventually lived symbiotically within larger cells, forming modern day eukaryotes.
2.Eukaryote, any cell or organism that possesses a clearly defined nucleus. The eukaryotic cell has a nuclear membrane that surrounds the nucleus, in which the well-defined chromosomes (bodies containing the hereditary material) are located.
