What could cause the differences in the amino acids sequences for these proteins in different organisms?
The reason of differences in the amino acids sequences with respect to the proteins in different organisms should be because of the sequence.
Reason of differences in the amino acids:The protein should be comprise of the polypeptide backbone along with the chains that are attached.
Each and every type of the protein should differed in the form of sequence and the no of amino acids.
Also, it does have the sequence of the chemically distinct side chains.
Therefore, in this way it have the difference.

Explanation:
Differentiate between the layers of the Earth based upon physical properties AND explain the flow of heat within and between the layers of the Earth.
Answer:
The Earth can be divided into 5 main layers according to their physical properties: the lithosphere (most superficial layer of the Earth: rigid and cold), the asthenosphere (Second most superficial layer of the Earth: soft and ductile), the mesosphere or lower mantle ( Middle layer of the Earth: rigid and hot, able to flow gradually), the outer core (Second innermost layer of the Earth: liquid) and the inner core (innermost layer of the Earth: solid). The flow of heat inside the Earth will depend on the temperature and the characteristics of the material. The crust behaves like a solid and has relatively low temperatures. The mantle behaves like a fluid and since convection is much more efficient in this case, that is the main means of transport, even though the relatively high temperatures make it possible for energy to also be transported by means of radiation.
Explanation:
As you descend into the Earth's interior, the temperature, pressure, and density of the rocks gradually increase. The Earth can be divided into five main regions based on its physical properties (temperature and pressure) and according to its mechanical resistance: lithosphere the chemical composition of this layer is notably different, it also acts as a unit that shows a rigid behavior (not can be bent), mainly because it is cold and consequently resistant, asthenosphere located in the upper mantle (at a depth of about 660 km), there is a comparatively plastic soft layer, mesosphere (lower mantle) more rigid layer and it is because as the pressure increases, it counteracts the effects of the higher temperature and the resistance of the rocks increases gradually with depth. Despite their resistance, the rocks of the mesosphere are still very hot and are able to flow in a very gradual way, the outer core is a 2270 km thick liquid layer. The convective currents of iron in this area are those that generate the Earth's magnetic field and the inner core of the material is more resistant than the outer core (due to the enormous pressure to which it is subjected) and behaves like a solid. When penetrating the crust of the Earth a change in temperature is observed, in general it increases; this variation in temperature with depth is called a geothermal gradient. The heat flux on the Earth's surface is calculated as the product of the geothermal gradient and the thermal conductivity of the rocks, these two parameters being directly determined. The Earth is basically made up of three concentric layers: the innermost core has a composition of cast iron at a temperature of over 4,000 ºC; the mantle that is the intermediate layer formed by iron and magnesium silicates and its temperature varies from 4,000 ºC in its contact with the core to 800-1000 ºC of its outer surface that contacts the crust that is the most superficial layer and visible by man. This crust has a variable thickness of 5 to 35 km and is made up of aluminum and magnesium silicates, its temperature varying between 800-1000 ºC of contact with the mantle and 15-20 ºC of the surface that we know.

Type of democracy where citizens elect leaders to represent them in government dictatorship representative democracy oligarchy anarchy
Answer:
representative democracy
Explanation:
Democracy can be defined as a government of the people, by the people and for the people.
There are two (2) main types of democracy and these include;
I. Representative democracy: it's also known as indirect democracy and can be defined as a form of government which typically involves the process of having the citizens of a particular country vote to elect representatives (political leaders) to enact laws, create policies and make decisions on their behalf.
Hence, representative democracy is a type of democracy where citizens elect leaders to represent them in government.
II. Direct democracy: it can be defined as a process which typically involves the candidates voting for their preferred choice. Thus, their choices are reflected directly on the subject matter.
Generally, the type of government in which legislators such as senators or house of representative members are found is known as a democracy and they are saddled with the responsibility of enacting or making laws.

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.

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.

Describe the pressure changes that occur in the lungs during breathing for someone with emphysema
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.
