Two colleagues that share the same office are exposed to the flu virus one week in January. Janet just recovered from the same flu virus two weeks earlier, while Mark has not been sick yet this winter. Which person do you expect would be more likely to become sick with this flu virus and why?
Janet: since she already had the flu, her immune system is weaker than Marks.
Janet: she will most likely get the flu again, and a more severe case of it.
Mark: he has not acquired any active immunity to the flu, and Janet has.
Mark: he has only passive immunity to the flu which will not benefit him in this case.
I believe Mark is more likely to get sick with the flu virus because Janet has acquired a slight immunity because she was infected with it while Mark has not been infected with the virus

A student is investigating mitosis by examining detailed pictures of the process the student wants to observe the formation of the nuclear envelope.the student should focus on pictures of which phase of mitosis
telophase
,prophase
,metaphase
,anaphase
Answer:prophase
Explanation:
Telophase, the fifth and final stage of mitosis, occurs when a parent cell's replicated genetic material is split into two identical daughter cells.
What is mitosis?Mitosis is a stage of the cell cycle during which replicated chromosomes are separated into two new nuclei. Mitosis results in the formation of genetically identical cells with the same number of chromosomes. As a result, mitosis exists as also referred to as equational division. Mitosis is the division of a single cell into two identical daughter cells (cell division). Mitosis is a nuclear division process that occurs in eukaryotic cells when a parent cell divides to produce two identical daughter cells. Mitosis is the separation of the duplicated genetic material carried in the nucleus during cell division.To learn more about mitosis, refer to:

g It has been proposed that integrin proteins undergo conformational changes when they bind to small molecules diffusing into the extracellular matrix. Because integrins are transmembrane proteins, a change in their conformation can be transmitted across the membrane to the portion of the protein that interacts with intracellular structures. What biological role does this allow integrins to play in a cell's function within a multicellular organism
Answer:
Cell-cell communication
Explanation:
Integrins are heterodimeric transmembrane receptors that facilitate the adhesion to the cell-extracellular matrix by attaching the cytoskeleton to this matrix. Moreover, integrins also help the cells bind with other cells. Integrins are responsible for the communication between cells and thus control tissue structure. These receptors are responsible for the attachment of fibroblasts to collagen, as well as the attachment of fibroblasts to fibronectin. It is also important to highlight that the binding of integrins with their corresponding ligands activates signaling pathways that control diverse cellular processes including, among others, cell growth, cell development, cell migration, phagocytosis, etc.

Answer:
its C, carrying capacity
Explanation:
I don't know I'm smart I guess lol
Carrying capacity is the maximum number of species an environment can support. Therefore, option "C" is correct.
What is carrying capacity?Carrying capacity is the average number of the particular species that a be supported by a partial habitat is known as carrying capacity. The importance of the carrying capacity is that it helps in the determination of the size of the population that can be tolerated and supported by a particular environment.
The limiting factors of the area of habitat are water, availability of food, and space. The ways to increase the carrying capacity of the are the elimination of the competitor and decrease in the number of predators.

Explain in detail how to decide the number of replications in a simulation study. Use fixed-sample-size and sequential procedures as examples. Describe the pros and cons of these two procedures
Explanation:
Fixed sample size:
In this fixed sample size the data is studied and checked in order to find a relationship. The benefits it is easy to produce, and with it less reliable outcomes can be given.
Sequential procedures:
→Sequential procedures helps while we are collecting the data.
→At an interim analysis, data collection can be stopped whenever the results are convincing enough to conclude an effect is present.
→Or otherwise the more data can be collected, or if needed the study can be terminated whenever it is extremely unlikely the predicted effect will be observed if data collection would be continued.
→In this two or more blocks of different sizes are prepared for testing.
→Pros being it provides better results and is less time taking, as we can stop once the relation is seen, con being it is difficult to perform.

Which class of protozoa shows nuclear dimorphism:
Answer:
Protozoan Tetrahymena
hope it helps!
Protozoa are eukaryotic organisms that are single-celled and free-living. Paramecium and Tetrahymena are the members of the ciliated class of Protozoan showing nuclear dimorphism.
What are Protozoa?Protozoans has been defined as unicellular eukaryote that is either parasitic or free-living. Ciliate is one of the classes of Protozoans that are characterized by the presence of cilia on the outer surface of the body.
The genus Paramecium and Tetrahymena of ciliated Protozoans show nuclear dimorphism as they have two different types of nuclei in their cell. One of the nuclei is somatic and the other is germline.
This property of nuclear dimorphism is seen in the lower organism like the Protozoans that needs a micronucleus for reproduction and the other macronucleus for the functioning and regulating of the cell. This property of the Protozoans makes them different from the other eukaryotes that possess only a single nucleus in their cell.
Therefore, the ciliated class of Protozoans shows nuclear dimorphism.

Explanation:
Red-shift
Emission spectra
Light from a star does not contain all the wavelengths of the electromagnetic spectrum. Elements in the star absorb some of the emitted wavelengths, so dark lines are present when the spectrum is analysed. Different elements produce different patterns of dark lines. The diagram shows part of the emission spectrum of light from the Sun.
A gradient colour spectrum of the sun.
Spectra from distant galaxies
Astronomers can observe light from distant galaxies. When they do this, they see it is different to the light from the Sun. The dark lines in the spectra from distant galaxies show an increase in wavelength. The lines are moved or shifted towards the red end of the spectrum. This effect is called red-shift. The diagram shows part of the emission spectrum of light from a distant galaxy.
A gradient colour spectrum of a distant star.
Red-shift and speed
Astronomers see red-shift in virtually all galaxies. It is a result of the space between the Earth and the galaxies expanding. This expansion stretches out the light waves during their journey to us, shifting them towards the red end of the spectrum. The more red-shifted the light from a galaxy is, the faster the galaxy is moving away from Earth

how might the biotic and abiotic features change during different seasons?
Answer:
The biotic and abiotic features change during different seasons through various factors.
Explanation:
Biotic and abiotic factors are referred to as the living and non living components of the ecosystem respectively. An example of biotic factor include plants, animals and an example of abiotic factors are water, sunlight etc.
The biotic and abiotic features change during different seasons through various factors. Biotic factors in dry season for example will lead to a decrease in abiotic factors such as rainfall and increase in abiotic factors such as sunlight while leading to a decrease in biotic factors such as plants and animals through the lack of water vital for them.
Biotic factors in wet season for example will lead to a increase in abiotic factors such as rainfall and decrease in abiotic factors such as sunlight while leading to a increase in biotic factors such as plants and animals.

How are the endoplasmic reticulum and Golgi apparatus
similar?
Both contain their own kind of DNA.
O Both are made up of membranes consisting of a lipid bilayer.
O Both are involved in producing chemical energy for the cell.
O Both are found only in plant cells and not in animal cells.
Answer:
Both are made up of membranes consisting of a lipid bilayer.
Explanation:
A cell can be defined as the structural, fundamental, biological and functional unit of life. Cells are found in all living organisms because they are the basic unit of life.
Generally, cells have the ability to independently replicate themselves. These cells can be compared to the kind of structures found in a business or factory, where you have different workers performing different functions.
In a cell, the "workers" that perform various functions or tasks for the survival of the living organism are referred to as organelles.
Golgi apparatus is like a packaging unit because it prepares the protein for export by chemically tagging them.
Also, the endoplasmic reticulum is like an assembly line because it is where the ribosomes perform their tasks.
Hence, the endoplasmic reticulum and Golgi apparatus are similar because both are made up of membranes consisting of a lipid bilayer.
