1.A virus mutates, and therefore it has which of the following traits of living things?(1 point) It uses energy

It evolves.

It grows and develops.

It is made of cells.

2.Compare a virus to a unicellular organism.(1 point)

Viruses reproduce through asexual reproduction; unicellular organisms need a host cell.

Neither unicellular organisms nor viruses respond to stimuli.

Unicellular organisms have a cell membrane made from a lipid bilayer; viruses have a protein coat.

Viruses need energy; unicellular organisms do not need energy.

3.Summarize the lytic cycle.(1 point)

A virus copies its genetic material and then splits its cell membranes in half to form identical viruses.

A virus lays eggs on the host cell’s protein coat, which then hatch and move on to infect other cells.

The viral DNA incorporates itself with the host cell’s and replicates whenever the host cell replicates itself.

A virus injects its genetic material into the host cell, copies itself, and then forms new viruses that burst out of the host cell.

4.Differentiate between the lysogenic and lytic cycles.(1 point)

The host cell copies its own DNA during the lytic cycle.

The host cell is destroyed during the lytic cycle.

The virus injects DNA into the host cell during the lysogenic cycle.

Viral proteins are synthesized during the lysogenic cycle.

5.Infer why doctors recommend people, especially elderly and those with weak immune systems, get the flu vaccine every year.(1 point)

They should get the flu vaccine because viruses mutate.

They should get the flu vaccine because their bodies already have a resistance.

They should get the flu vaccine because viruses do not mutate.

They should get the flu vaccine because their bodies do not build up resistance.

Please i really need help

Some technological solutions to problems like global warming meet the specific needs and situations of local communities. an example from india involves converting the solid waste from cattle into clean-burning fuel for cooking. this reduces the amount of greenhouse gases, specifically methane and carbon dioxide, released into the environment from wood fires. when evaluating the feasibility of implementing this solution, computer models are used to weigh costs against benefits. what factor is least likely to impact the decision on adopting this technology?

Punnett squares are used to show possible combinations of alleles or to predict the probability of a trait occurring in offspring. an incomplete dominance cross is performed between a bird that is homozygous for red feathers and a bird that is homozygous for blue feathers. purple offspring result. then, two of the purple offspring are crossed. according to the punnett square for this cross, how many of the offspring from the second cross will have a feather color that results from incomplete dominance? 1 in 4 2 in 4 3 in 4 4 in 4

Neeed now for 1. eye color is a polygenic trait. what is the possibility of getting a green (aabb) eyed child, if parent 1 has brown eyes (aabb) parent 2 has blue eyes (aabb) 2.albinism is a recessive trait. having normal pigment is the dominant trait. what is the possibility of having an albino child if parent 1 is heterozygous normal parent 2 is heterozygous normal 3.in rabbits black fur is dominant over white fur. what is the probability of getting a rabbit with black fur if parent 1 is heterozygous black parent 2 is homozygous white
