Amoeba moves using pseudopodia.
Euglena moves using flagellum.
Paramecium moves using cilia.
What are the structures that allow the movement in different protists?
Pseudopodia, or protruding portions, are used by amoebas to move. Its meaning is "false feet." These are membrane elongations of the cell. With its pseudopod, an amoeba can reach out and grab a surface, using it to propel itself forward.Flagellums (plural flagella), a long whip-like structure that functions as a little motor, help euglena move. On the anterior (front) end, the flagellum spins in order to propel the cell through the water.Cilia have the ability to move in unison to advance a Paramecium. When a barrier is reached, the cilia travel in the opposite direction, somewhat reversing the Paramecium's forward motion.

When does DNA replication occur within the cell cycle?
Answer:
Interphase
Explanation:
The S phase of a cell cycle occurs during interphase, before mitosis or meiosis, and is responsible for the synthesis or replication of DNA. In this way, the genetic material of a cell is doubled before it enters mitosis or meiosis, allowing there to be enough DNA to be split into daughter cells.
What is the goal of the cell cycle? *
5 points
To maintain cell homeostasis by maintenance of the cell membrane
Regulation of cellular activities related to energy conversion
Provide the cell with the needed nutrients for surival
The correct replication of DNA, followed by the correct division of DNA, to create two
identical daughter cells
Answer:
The correct replication of DNA, followed by the correct division of DNA, to create two identical daughter cells
Explanation:
The most basic function of the cell cycle is to duplicate accurately the vast amount of DNA in the chromosomes and then segregate the copies precisely into two genetically identical daughter cells.

People can swallow the eggs of tapeworms by consuming unclean food or water. Tapeworms can live in the digestive systems of humans where they grow and feed off the food the person eats. As a result, the person does not receive proper nourishment and becomes ill.
Which of the following explanations BEST describes the relationship that exists between the humans and the tapeworms?
Answer: Parasitism
Explanation:
You didn't give the options and I couldn't get them online but based on the information given, the relationship is parasitism.
Parasitism is a refered to as a symbiotic relationship that exists between organisms such one organism, which is known as the parasite, either lives on the other organism which is called the host or lives inside it and causes the host harm.
In this case, the parasite benefits at the expense of the host. Examples of parasites include tick, fleas and tapeworms.
With regards to the question, the tapeworm causes people harm and benefits at the expense of its host.
Answer:
Parasitism
Explanation:
The relationship between the humans and the tapeworms is parasitism because the tapeworms are getting food, but the human is losing nutrients in the process.

Identify the major players shown in the simulation: mRNA, Codon, Amino Acid, tRNA, anticodon, ribosome.
Answer:
mRNA, tRNA and ribosome
Explanation:
mRNA, tRNA and ribosome are the major players because they perform a very important functions. Messenger RNA (mRNA) is a molecule in cells that carries instructions in the form of codes from the DNA to the sites of protein synthesis which is a ribosomes. Transfer RNA (tRNA) is a type of RNA molecule that helps in decoding a messenger RNA (mRNA) into a protein. Ribosome is an organelle present in the cell that is responsible for the production of proteins according to the instruction given by DNA.
if perimeter of a square is 24cm find its area please give me easy formula
Answer:
4l = 24
so l=6
now
l*l =6*6
= 36 square cm
Answer:
36cm²
Explanation:
Perimeter of a square = 4x (sum of all 4 sides)
Perimeter = 24 cm (given)
[tex]\implies [/tex]4x = 24
x = 24/4 = 6 cm
Now, area of a square = (side)²
Area = (6)²
= 36 cm²

Severe acute respiratory syndrome (SARS) is an illness caused by a coronavirus. Symptoms, including a high fever, headaches, and body aches, typically occur two to seven days after infection by the virus. This information suggests that the reproductive cycle of the SARS virus is - lysogenic, because the virus is a coronavirus. lysogenic, because the virus is a coronavirus. lysogenic, because the virus primarily affects older people. lysogenic, because the virus primarily affects older people. lytic, because the virus causes respiratory illness. lytic, because the virus causes respiratory illness. lytic, because of the quick onset of symptoms after infection.
Answer:
lytic, because of the quick onset of symptoms after infection
Explanation:
As seen in the question above, the SARS virus tends to develop symptoms very quickly when it is infecting a person. This speed in the development of symptoms is a characteristic of the lytic cycle, in relation to the reproductive cycle of viruses. This is because in the lytic cycle, a virus can infect many cells at once, which accelerates the development of the disease. This cycle allows the virus to use all of the cell's biological machinery to reproduce more copies of the virus. When these copies are ready, the virus causes the destruction of the host cell and the release of new viruses to other cells, where the whole process will be repeated. This is all done very quickly.
The lysogenic cycle does not cause the rapid infection of thousands of cells, since it is necessary that there is an adaptation between the DNA of the cell and the DNA of the virus. This slows down the infection process and, therefore, symptoms appear more slowly.
Answer:
lytic, because of the quick onset of symptoms after infection

which plant structure is most similar in function to a lizards eggs?
answer choices:
flowers
pollen
seeds
stems
(pls don’t guess or leave links)
Answer:I would say seeds, since it protects the bud of a flower and then the flower “hatches” from the seed and grows
Explanation:
The plant structure that is similar in functions to eggs is seeds. The correct option is C.
What are seeds?A seed is an embryonic plant with a protective outer covering and a food reserve. The formation of the seed is a part of the reproduction process in seed plants, including gymnosperm and angiosperm plants.
Similarly, an egg is an oval or round object laid by a female bird, reptile, fish, or invertebrate that typically contains a developing embryo.
Bird eggs are protected by a chalky shell, whereas reptile eggs are protected by a leathery membrane.
Embryos are developing in seeds and eggs. Both provide food for the developing embryo. Both have protective coverings that keep them from drying out.
Thus, it can be concluded that the correct option is C.

A. food pyramid
B. food chain
C. food web
D. food log
Hello!
Let's look at some definitions!
A food pyramid is levels of predators, in an pyramid shape to show the successive.
That does not match the definition your question provided, so we can move on.
A food chain is a series of animals who depend on each other for food/buisness.
Again, it does not match, this is a series, not an entire ecosystem.
A food web is a connection of food chains, which show the entire relationships of an ecosystem.
This definition is fairly close to the listed definition, lets keep this in mind.
A food log is a chart of what you eat each day.
Trick answer! This has nothing to do with the subject.
Given these choices, the correct answer is:
Food Web
