Answer:
A virus surface proteins are organized to help penetrate host mucus.
Explanation:
The surface of viruses includes many copies of one type of protein that binds, or adsorbs, specifically to multiple copies of a receptor protein on a host cell.
The surface protein of influenza virus, hemagglutinin, helps the virus attach and enter host cells.
What are surface proteins?The surface protein on the influenza virus is called hemagglutinin (HA) and it plays a critical role in the virus' ability to infect host cells. HA is a glycoprotein that protrudes from the surface of the virus and binds to specific receptors on the surface of host cells, particularly in the respiratory tract.
This allows the virus to enter the host cell and hijack its machinery to replicate and produce more virus particles. The HA protein also enables the virus to evade the immune system by constantly changing its structure through a process called antigenic drift, which prevents recognition by the host's antibodies.
The importance of the HA protein makes it a prime target for the development of vaccines and antiviral drugs against influenza.

What are some factors that could affect a forensic entomologist's estimate of PMI?
Answer:
Temperature , Insects and Time
Explanation:
Including some of the most common variables influencing post-mortem period predictions are thoroughly investigated, like temperature, grave size, and parasite exposure to the bone. Diptera are also the insects of highest forensic concern because of their behavior and massive worldwide spread.
How did the temperature relate to the “recommended temperature limit” (solid horizontal red line)?
Will give extra points for right answer
Answer:
The “recommended temperature limit” indicates limit of the temperature that is good for our world.
Explanation:
The temperature related to the “recommended temperature limit” means that in the graph there is a limit of temperature for our world's environment. if the temperature is between this limit, there is less or no adverse effect on our environment while on the hand, if the temperature exceeds from this limit, then it adversely affected our world because the concentration of carbondioxide gas in the atmosphere increases due to this increase temperature.

Na3C6H507
Answer:
Explanation:
Trisodium citrate has the chemical formula of Na3C6H5O7. It is sometimes referred to simply as "sodium citrate", though sodium citrate can refer to any of the three sodium salts of citric acid. It possesses a saline, mildly tart flavor. It is mildly basic and can be used along with citric acid to make biologically compatible buffers
Sodium citrate is chiefly used as a food additive, usually for flavor or as a preservative. Its E number is E331. Sodium citrate is employed as a flavoring agent in certain varieties of club soda. It is common as an ingredient in bratwurst, and is also used in commercial ready-to-drink beverages and drink mixes, contributing a tart flavor. It is found in gelatin mix[clarification needed], ice cream, yogurt, jams, sweets, milk powder, processed cheeses, carbonated beverages, and wine[citation needed], amongst others.

Imagine that you are a drop of blood. What path would you follow through a human's body as you travel from the left little toe, through the heart, and into the right big toe?
Answer:
a. Heart
b. pulmonary artery
c. lungs
d. pulmonary vein
e. heart
f. aorta
g. arteries
h. big toe.
Explanation:
First I ( drop of blood) will go from the heart to the lungs through pulmonary artery in order to purification from carbondioxide and loaded oxygen. After that, I return to the heart through pulmonary vein and the heart pump this blood to the aorta which is a big blood vessel that branched into small arteries that reaches to every cell of the body and through these arteries I reach the big toe of the foot.

what would happen if igneous rock was first exposed to the energy from the and then millions of years later to energy from earth's interior?
Answer:
If there is too much heat or pressure, the rock will melt and become magma. This will result in the formation of igneous rock, not a metamorphic rock. Consider how granite changes form. Granite is an igneous rock that forms when magma cools relatively slowly underground.
Explanation:
Gradually, the sediment accumulates in layers and over a long period of time hardens into rock. Generally, sedimentary rock is fairly soft and may break apart or crumble easily. You can often see sand, pebbles, or stones in the rock, and it is usually the only type that contains fossils

How can a material at a certain temperature have all of its molecules at the same energy?
Answer:
The average kinetic energy of the molecules is proportional to absolute temperature. At any given temperature, the molecules of all gases have the same average kinetic energy.
Explanation:
When heat is added to a substance, the molecules and atoms vibrate faster. As atoms vibrate faster, the space between atoms increases. The motion and spacing of the particles determines the state of matter of the substance. Solids, liquids and gases all expand when heat is added.
