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.

Explanation:
These are the answers I chose from when i did it 10 minutes ago, they wont let me go back to the quick check to confirm it, but this was the best I could do.
The trait of living things that's depicted by a virus that mutates is that it evolves.
The difference between a virus and a unicellular organism is that Unicellular organisms have a cell membrane made from a lipid bilayer; viruses have a protein coat.
The lytic cycle is when a virus injects its genetic material into the host cell, copies itself, and then forms new viruses that burst out of the host cell.
The difference between the lysogenic cycle and the lytic cycles is that the host cell is destroyed during the lytic cycle.
The reason why doctors recommend people, especially the elderly and those with weak immune systems, get the flu vaccine every year is because they should get the flu vaccine because viruses mutate.
It should be noted that when a virus mutates, it shows its ability to evolve. In such a case, there's transformation and development regarding the virus.
People are advised to get the flu vaccine every year because viruses mutate. In this case, getting the flu vaccine will help protect the person from the virus.
Getting a flu vaccine is vital especially for the people that have a low immune system as well as for the older people who are already weak.

Describe the process of germination and plant growth you observed in the lab activity for a monocot plant.
Answer:
Germination is the process by which a plant develops from a seed. The most common example of germination is a sprout of a seedling emerging from the seed of an angiosperm or gymnosperm. However, the development of a daughter spore from a spore, such as the growth of a mycelium from a fungal spore, is also germination. Therefore, germination can be understood in the general sense as anything that becomes larger from a small entity or a living organism, is a commonly used method in many seed development projects. alike.

What is desertification?
a.
method of using desert land for agriculture
b.
the process of turning arable land into deserts
C.
drying up of stream beds and lakes
d.
the expansion of current deserts land areas
Answer:
B
Explanation:
I believe it's B because desertification is the process of land being turned into deserts due to many factors like animal grazing.
Desertification means the process of turning arable land into deserts, which is the second option. Desertification is a process in which agricultural land is affected the most, resulting in the land having fewer nutrients.
What is desertification?Desertification is a process in which arable land is affected, and as a result, crop production is reduced. Desertification is the result of many factors, such as climate change, rapid urbanization, population growth, global warming, etc. The less water, nutrients, and microbes there are in the soil, the more likely it is that the land will become a desert.
Microbes in the soil become extinct as a result of climate change, causing crop patterns to shift and more land to become desert. Global warming causes temperatures to rise and many species to become extinct, exacerbating the problem.
Hence, desertification means the process of turning arable land into deserts, which is the second option (b).

Which is the best interpretation of the two flat portions of the graph?
A. These show where the temperature is 0ºC.
B. These show where changes of state are occurring.
C. These show where kinetic energy is increasing.
D. These show where thermal energy does not exist.
Answer:
B, they are changes of state.
The best interpretation of the two flat portions of the graph where these shows that change of state are occurring. Thus, C is correct option.
What are change of state?A state is physical condition of any substances it means that any substance which found on earth are mainly found in three states and these are following:-
1- Solid
2- Liquid
3- Gas
A change of state is physical change of state i.e any substance which changes their state from ( solid to liquid called melting), (liquid to gas called evaporation), (gas to solid called diffusion) etc are called change of state.
These change of state occurs when temperatures or pressure changes in a system or substances. When the temperature or pressure increase the interaction between the molecules also increases.
Therefore,the best interpretation of the two flat portions of the graph where these shows that change of state are occurring. Thus, C is correct option.

Conjugation differs from reproduction because conjugation Group of answer choices transfers DNA horizontally, to nearby cells without those cells undergoing replication. transcribes DNA to RNA. replicates DNA. transfers DNA vertically, to new cells. copies RNA to make DNA.
Answer:
it is differs from reproduction because conjunction group of answers
Conjugation transfers DNA horizontally, to nearby cells without those cells undergoing replication.
Conjugation is a mechanism of genetic transfer in bacteria where genetic material, usually in the form of plasmids, is transferred from one bacterial cell to another. Unlike reproduction, which involves the replication and inheritance of genetic material through cell division, conjugation allows bacteria to transfer genetic material horizontally between cells that are in close proximity to each other.
During conjugation, the donor bacterial cell containing the plasmid makes contact with the recipient cell through a specialized structure called a pilus. The plasmid DNA is then transferred from the donor cell to the recipient cell through this pilus. The transferred DNA can include genes that provide advantages such as antibiotic resistance or the ability to metabolize certain substances.
The key difference between conjugation and reproduction is that conjugation does not involve replication of the recipient cell's entire genome. Instead, it transfers specific genetic material from one cell to another. The recipient cell does not undergo replication as a result of conjugation but acquires new genetic information from the donor cell.
Reproduction, on the other hand, involves the replication and inheritance of the complete set of genetic material in the parent cell. It results in the production of offspring cells that are genetically identical or similar to the parent cell.
In summary, conjugation is a form of genetic transfer in bacteria where DNA is horizontally transferred between cells without those cells undergoing replication. It allows for the exchange of genetic material and the acquisition of new traits by recipient cells. Reproduction, on the other hand, involves the replication and inheritance of genetic material through cell division.

A microbiologist is characterizing a newly discovered microorganism that requires an anaerobic environment to live and uses either lactic acid or alcoholic fermentation in its energy metabolism. Which would be a way to determine the type of fermentation the microorganism uses
Answer:
The correct answer is - Analyze whether one molecule of CO2 is released for every one molecule of glucose fermented
Explanation:
Fermentation can be described as the process that breaks down the glucose-like molecules in absence of oxygen or anaerobically. There are different types of fermentation depending on the items they produce in used those products. The three types of fermentation are Lactic acid fermentation, alcoholic fermentation, and acetic acid fermentation.
One can determine the type of fermentation by analyzing the products they produced and the amount of carbon dioxide they produce for every one molecule of glucose fermented as lactic acid fermentation do not produce carbon dioxide whereas alcoholic fermentation produces two moles of CO2 per mole of glucose.

Which sentence in the passage points out the similarity between parthenogenesis and sexual reproduction?
Answer:
Parthenogenesis is a type of reproduction that does not require a mate. It’s rarely seen in birds and higher vertebrates. Parthenogenesis involves the formation of a zygote. But this zygote is formed without fertilization. In parthenogenesis, in the absence of a male gamete, the ovum develops directly in the zygote.
Explanation:
The sentence in the given passage that points out the similarity between the parthenogenesis and sexual reproduction is “Parthenogenesis involves the formation of a zygote”. It is a form of reproduction in which an ovum is produced without fertilization. Zygote formation us a common process in sexual as well as asexual type of reproduction process.
