what contributes to antigenic shift in influenza viruses?
Answers
Answer:
The particular structure of the influenza virus genome and function of its viral proteins enable antigenic drift and antigenic shift.
Answer:
Between worldwide outbreaks, known as pandemics, influenza viruses undergo constant, rapid evolution (a process called antigenic drift ), which is driven by mutations in the genes encoding antigen proteins.
Antigenic shift is the process by which two or more different strains of a virus, or strains of two or more different viruses, combine to form a new subtype having a mixture of the surface antigens of the two or more original strains. The term is often applied specifically to influenza, as that is the best-known example, but the process is also known to occur with other viruses, such as visna virus in sheep. Antigenic shift is a specific case of reassortment or viral shift that confers a phenotypic change.

The variety of different genes in a population of organisms
Explanation:
Genetic Diversity is in fact the overall range of individual and varying characteristics in a population. Genetic diversity is what makes different organisms and species unique, and even usher in traits that become favorable for survival. Without genetic diversity, many species would die out before evolving (because it would be near impossible to evolve with their surroundings without genetic diversity).

Which layer of the
earth has the greatest
density? Why?
Answers
Answer: metal inner core
Explanation:
It is made of the densest components & it is under the greatest compression; due to the overlying layers.
The inner core of Earth has the greatest density due to:
- The inner core is made of solid iron and nickel
- The inner core gets consolidated due to pressure exerted by the other top layers.
What are the different layers of the Earth?
Generally the Earth is made of three different layers:
- Crust- The outer layer
- Mantle - The Middle Layer
- Core - The Inner Layer.
Crust:
Outer layer of the Earth and is thin, brittle and cold compared to other layers.
It is majorly made of light elements especially silica, aluminum and oxygen.
The thickness of crust varies for for land and ocean where the former is thicker than latter.
Mantle:
It is around 3000 km thick and is the thickest layer of the Earth. It starts mere at 30 km from the earth's crust.
It is majorly made of Iron, Magnesium and silicon and is dense, hot and semi solid.
The upper part of the mantle is liquid in nature called as Asthenosphere and it is believed that tectonic plates rides upon here and slide across.
Core:
Core is further divided into Outer core and Inner core.
Outer core is made of iron and nickel and is liquid in nature. It is heated largely by the radioactive decay of the elements of the uranium and thorium and this liquid churn huge turbulent current.
Inner core is a solid metal ball having radius of 1220 km. It is extremely dense and is mostly made of iron and nickel.
The temperature of inner core is similar to that of the surface of sun along with high amount of pressure.
Thus this layer has the greatest density amongst all the layers of the Earth.

Name four ways synthetic fibers are different from each other?
*forensic science*
Answers
Synthetic fibers can vary greatly from one another. The main reason they can have such varying characteristics is that they can be of four distinct types.
Synthetic fibers are those that cannot be found in nature, but rather are created by man. They can be of four types:
Nylon RayonPolyesterAcrylicRayon is one of the types of synthetic fibers created by man. One of the weaker fibers, It is commonly referred to as synthetic silk, having many properties similar to those of silk. It is the result of wood pulp being fused with cotton or wool and is commonly used to create beddings and other home decorations, in varying colors.
Nylon shares few, if any, characteristics with rayon. It is a strong and elastic synthetic fiber. In fact, nylon is stronger than steel wire, even though it is created from water, coal and air. Nylon can be found in tents, climbing equipment, toothbrushes, and many more everyday appliances.
Polyester is a stranger form of synthetic fiber. As its name implies, it is formed from the repetition of esters. Polyester is often used for dressing, given its wrinkle-free properties and resistance. However, many kinds of polyesters exist, leading to its use in bottles, wires and more.
Finally, Acrylic is the final kind of synthetic fiber. Acrylic is a fiber which is normally used to replace wool. Acrylic can be seen used in blankets and sweaters. It is also often used to create panels that will imitate glass, which shows exactly how flexible and useful synthetic fibers can be.

The structural elements of a virus, such as the capsid, envelope, and spike proteins, serve to protect and deliver the viral genome into host cells for replication.
What are the structural elements of a virus?The structural elements of a virus have different functions that are essential for the survival and replication of the virus. These elements include:
Capsid: The capsid is the protein shell that surrounds the viral genetic material. It provides protection to the viral genome and determines the shape and size of the virus.Envelope: Some viruses are surrounded by an envelope, which is a lipid membrane that covers the capsid. The envelope helps the virus to evade the host's immune system and enter the host cell.Spike proteins: Spike proteins are protruding structures on the surface of the envelope that are used to bind to the host cell. They play a crucial role in the process of virus entry into the host cell.Nucleocapsid: The nucleocapsid is the complex of the viral genome and the capsid. It is responsible for protecting and delivering the viral genetic material into the host cell.Tail fibers: Some viruses have tail fibers, which are structures that help the virus to attach to the host cell and initiate the entry process.Learn more about virus, here:
