Proteins on the surface of a human cell and on a bird influenza virus are represented in the diagram below. Describe a change in the bird influenza virus that would allow it to infect this human cell.
Answer:
Viral proteins can modify the most superficial portion in such a way that it is complementary to the receptor of the human cell.
Generally this happens due to a genetic recombination between an avian virus and a human virus within the respiratory epithelium of the pig: this process underlies the emergence of new, more virulent strains of the influenza virus and underlies the emergence of influenza pandemics

Which is common to the life cycles of both flowering and non-flowering plants?
Answer:
Explanation:
Nonflowering plants include ferns, mosses, mushrooms, and many trees. It's obvious nonflowering plants are different from flowering plants because they don't have flowers, but there is also a difference in how they reproduce. While flowering plants only use seeds, nonflowering plants use either seeds or spores.

A drought decreases the water level in Lake Winnipeg. The carrying capacity of the lake decreases.
Limiting factor?
Explain
Answer:
Water, fish
Explanation:
The limiting factors are the water of course and the organisms living in the lake.
A drought decreases the water level in Lake Winnipeg and the carrying capacity of the lake decreases. This is because it is:
Density IndependentWhen something is said to be density Independent with respect to ecology, it means that an external force is able to influence the volume of a habitat, notwithstanding the density.
As a result of this, this particular principle is in place here as a drought which is an external factor is able to affect the size of the water.

Why do large islands usually have more species than smaller islands?
Answer: Reason Why
Explanation: A bigger target is easier to hit than a small one, and a big island is more likely to have species land on it by chance than a small one is. Larger islands have more space than smaller islands, so there are likely to be more resources available for species to use. The opposite is true for smaller islands.
A researcher exposes a bacterial culture to UV radiation and then subjects it to progressively higher temperatures. As the temperature increases, the bacteria have a progressively harder time surviving. Analysis of the dead bacteria reveals large amounts of misfolded, aggregated proteins compared to wild-type control bacteria exposed to the same temperature increase. Which of the following is a plausible explanation for the data?
A. The ribosomes are mutated and are non-functional.
B. The initiator tRNA (fMet) has been mutated and is non-functional.
C. Molecular chaperones have been mutated.
D. DNA polymerase is mutated and non-functional.
Answer:
C. Molecular chaperones have been mutated.
Explanation:
In prokaryotes; transcription and translation occur consecutively. Protein doubling additionally happens following the translation. The heat stun proteins or molecular chaperones are imperative to assume a part in the appropriate collapsing of the protein. At high-ranging temperatures, the protein misfolding can be ascribed to a change in mutation of the molecular chaperones.

Vacuoles are pockets that collect water and the cell's junk. The nucleus sends commands to other cell parts and contains DNA.
Why it isn't A: Both have membranes.
Vacuole- tonoplast. Nucleus- Nuclear membran.
Why it isn't B: The Vacuole is not a thick fluid, though it may hold thick fluid.
Why it isn't C: This should be obvious.

In 1847, the German biologist Christian Bergmann noted that mammals and birds living at higher latitudes (farther from the equator) are on average larger and bulkier than related species found at lower latitudes. Suggest an evolutionary hypothesis to explain this observation.
Answer:
not quite sure how to do the hypothesis but its likely to be something to do with the fact that they need more fat and muscle due to the thinner atmosphere as respiration is harder to occur.
