Answer:

These changes probably would have taken place because of antigenic shift or to a smaller extent because of antigenic drift. The antigenic shift takes place when the segments of the influenza viral genome recombine in various ways, and this leads to major modifications to the proteins present on the surface.  

The individuals generally do not possess immunological memory to this novel strain of the virus, thus, the disease that they encounter can be more extreme in comparison to the infection with strains to which they possess certain immunological memory. The antigenic shift can result in influenza pandemics.

How do chemosyntheic organisms get energy
hichkok12 [17]

Answer:

Chemosynthesis is a process by which energy is derived via the microbial mediation of certain chemical reactions. The source of energy for chemosynthesis is energy liberated from a chemical reaction (the oxidation of an inorganic substance) rather than energy harvested from sunlight or other light.

Complete question: While taking a walk in a park, Muskaan observed an insect on a pitcher plant (Nepenthes). Immediately the flower opened up and the insect slid down. To which of the following categories does the pitcher plant belongs?

a) Saprophytes

b) Insectivorous

c) Parasite

d) Symbiotic

Answer:

The correct answer is option b. Insectivorous

Explanation:

A carnivorous or insectivorous plant is the one that obtains most of its nutritional necessities from the capture and consumption of protozoans or animals, especially insects and arthropods.

These insectivorous plants grow in poorly nutritional soil, so they need to get nutrients from their prey. These species attract and trap their prey, and by the action of specific enzymes and digestive bacterias, they can absorb the insects' nutrients.

These insectivorous plants make use of their flowers to trap the prey. These tramp flowers are cup-shaped, and at the bottom of this cup, there is a liquid where insects get trapped and die.

Insects are attracted by aromas produced by the edges of the trap and when they land, they slip and fall inside, and once drowned, the enzymes digest them.

How many nucleotides encode the identity of one of the 20 amino acids and is called a codon
m_a_m_a [10]

the size of a Codon is 3 nucleotides.

The 20 amino acids are encoded by combinations of four nucleotides

If a codon were two nucleotides, the set of all combinations could only encode 16 amino acids.

since Codons are made up of three nucleotides, the set of all combinations can encode 64 amino acids. {i.e. 64 different combinations of four nucleotides taken three at a time.} But of the total of 64 codons, 61 encode amino acids and 3 specify termination of translation.

I hope this Helps!
