Answer:
1. During the__ Attachment ____stage, enzymes digest cell wall and membrane material so that the viral nucleic acids can enter into the host cell.
2. During the ___ Penetration __ stage, the capsid of virus combines with receptors on the host cell's plasma membrane.
3. During the__ Biosynthesis ____stage, viral nucleic acids and capsid components are produced.
4. During the ___ Release __ stage, lysozyme enzyme is produced, is rupturing the cell membrane and releasing viral particles.
5. During the___ Maturation ___stage, viral nucleic acids and capsid components are assembled to produce viral particles.

They lack vascular system
Answer:
The expected ratio of the F_2 generation from F_1 generation will be
<u>9 "fabulous": 3 "smashing": 4 "plain" </u>
Explanation:
The expression of the phenotype will follow Mendel's Dihybrid cross.
plain→smashing
(only when allele A is present, which produces Enzyme 1)
smashing→fabulous
(only when allele B is present, which produces Enzyme 2)
Keeping the above statements in mind, in F_2 generation, only the genotypes having both A and B alleles will express phenotype "fabulous",as both Enzyme 1 and Enzyme 2 are required for that. The genotype having at-least one A allele and no B allele will produce the phenotype "smashing", as Enzyme 1,produced by allele A, will convert "plain" into "smashing". Hence, the dihybrid cross will as in the attachment.
Answer:
A
Explanation:
prometaphase is the process that seperates the duped genetic meterial carried on a nucleus
Answer:
e.) the biodiversity of the pond has decreased
Explanation:
Biodiversity or biological diversity refers to the variety of living organisms in a particular area. It can be a measure of number of species of living organisms in that area. The more the number of species, the higher the diversity and vice versa.
<em>Adjacent development close to the pond can be viewed as habitat disturbance. Habitat disturbance affects biodiversity in a number of ways including:</em>
- <em>A shift in the species composition of the habitat</em>
- <em>Outright extinction of certain species from the population</em>
<em>Overall, the species diversity become reduced as a result of a shift in species composition of extinction of some species. Hence, the best indicator of habitat disturbance is a decrease in biodiversity of the habitat.</em>
The correct option is e.
