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.

Which statements describe the synapse? Select all that apply.

It carries information through electrical impulses to the cell body.
It is part of the neuron.
It ensures that information travels in one direction only.
It carries information through chemical impulses to the cell body.
It is the gap between neurons.
It ensures that information travels in multiple directions.

How are mitosis and binary fission similar?
A. They produce identical daughter cells.
B. They occur only in prokaryotes.
C. They involve division of nuclei as well as cytoplasm.
D. They occur only during sexual reproduction.

Elodea is a plant that lives in water. Like all plants, elodea can make its own food through
process called photosynthesis. Oxygen gas is also produced during photosynthesis.
Photosynthesis can only happen in the presence of light. To measure the rate of
photosynthesis, a piece of elodea can be placed in an inverted test tube filled with a
sodium bicarbonate solution. Oxygen gas produced by photosynthesis will collect at the
top of the test tube.
A student has designed an experiment using elodea plants. The experimental setup is
shown in Figure 1-4
Which of the setups would serve as the control of the experiment?
Bucket
Lamp
Flashlight High
Natural
Elodea
Sodium
bicarbonate

2.1explain the body's hormonal response to dehydration​

An ecosystem experiences a loss of denitrifying prokaryotes. Will this loss affect the health of the ecosystem?

ASAP Determine whether the statement is true or false and why. “We have discovered a series of humanoid fossils that are similar to humans, but not human. Each of these humanoid species dates to a different period in time becoming more human-like the closer to the present they are, showing a clear evolution into humans.”
A. False, it should read “We have discovered no series of humanoid fossils that are similar to humans, showing a clear lack of any transitional fossils as evidence of human evolution”
B. True
C. False, it should read “We have discovered a series of humanoid fossils that are similar to humans, but not human. Each of these humanoid species dates to a different period in time becoming less human-like the closer to the present they are, showing a clear evolution away from humans.”
D. False, it should read “We have discovered a series of humanoid fossils that are similar to humans, but not human. Each of these humanoid species dates to the same period in time, showing that many human-like species existed at once, but all went extinct.”

The founder effect occurs when Multiple Choice large groups of individuals leave their home population and establish new settlements, mating only among themselves. small groups of individuals leave their home population and establish new settlements, mating only among themselves. many members of a population die, resulting in a great loss of genetic diversity. many members of a population reproduce causing too much genetic diversity within the population. small groups of individuals leave their home population and join established settlements, and mating with natives.

what is photosynthesis?​

Which of the following is true of living things that have prokaryotic cells when compared to living things that have eukaryotic cells?
They have many types of organelles.
They are types of plants.
O They are always larger than eukaryotic organisms.
They are always unicellular.

Question
Use the text to identify the sentences with evidence that matches the claim.

Claim 1 --> Tropical rainforests contain more biodiversity than all other biomes.

1) Biodiversity refers to the total number of different species of all kinds living in an area.

2) Tropical rainforests have many of the climate characteristics that organisms of different species need to grow, such as warm temperatures, plenty of rain, and many food sources.

3) There are large amounts of daily sunlight, which provides a great deal of energy to a variety of rainforest organisms.

4) Surprisingly, rain forest soil is very poor.

5) Due to the large amounts of rainfall, nutrients are leached out of the soil quickly.

6) Warm temperatures cause dead organisms to decay quickly, and the nutrients are then used by many different plants.
