Surface proteins are the proteins that are embedded in the cell membrane structure of organisms and help in cell interaction with the outer surrounding or other cells.
Surface protein on the influenza virus is needed for attaching to the host cell.
The surface protein of viruses can be explained as:In viruses, the genetic material is stored in these protein structures called capsids which protects the viral genetic material from degrading enzymes and other cellular enzymatic activities.Surface proteins on the viruses are needed to penetrate and attach to the host system and cells for inducing immune response and diseases.The surface proteins of influenza virus HA and NA are necessary for penetrating host mucus layers.Therefore, option B to attach to the host cell the surface proteins are needed.

Imagine there was no tilt to the earths axis and earths orbit was circular
Answer:
If the Earth was not tilted on its axis, there would be no seasons. And humanity would suffer.
Explanation:
When a Mars-size object collided with Earth 4.5 billion years ago, it knocked off a chunk that would become the moon. It also tilted Earth sideways a bit, so that our planet now orbits the sun on a slant.

What group of organisms is found at the base of every energy
pyramid?
Answer:
Plants or other photosynthetic organisms (autotrophs) are found on the first trophic level, at the bottom of the pyramid. The next level will be the herbivores, and then the carnivores that eat the herbivores. The energy pyramid (Figure below) shows four levels of a food chain, from producers to carnivores.

A scientist performed an experiment during which she measured the energy transferred in each step of her experiment. The total quantity of energy transferred in all of the steps was less than the amount she measured at the beginning. What is the most likely explanation for this result?
Answer:
Option D
Explanation:
The complete question is
A scientist performed an experiment during which she measured the energy transferred in each step of her experiment. The total quantity of energy transferred in all of the steps was less than the amount she measured at the beginning. What is the most likely explanation for this result?
a) Energy was destroyed during certain steps in the experiment.
b) The steps in the experiment required more energy than was available
c) The experiments created energy that was then used up at a faster rate.
d) Some energy was transformed into unwanted heat or sound that was not detected
Solution -
Option D is correct
While transfer of energy through any medium, some energy is lost in the form of heat and light. This loss of energy is not accounted at the beginning of the process and hence the initial energy loss was zero. With the succession of the process energy kept loosing and hence the final energy count was low at all steps.
