Which of the following characteristics would identify this cell as eukaryotic? Please answer ASAP.
Answer:
C) presence of a nucleus
Explanation:
A is incorrect because all cells have a cell membrane
B is incorrect because a flagella does not determine whether or not the cell is eukaryotic or prokaryotic
D is incorrect because a cell wall is used to differentiate an animal cell from bacteria, archaea, fungi, plants, and algae cells
Only eukaryotic cells have a nucleus
Hope this helps :) (maybe mark me brainliest?)
Presence of a nucleus would identify this cell as eukaryotic cell. Therefore, option (C) is correct.
What are features of an eukaryote?Eukaryotes are organisms with nuclei in each of their cells. Eukaryotes include all animals, all plants, all fungi, and many unicellular creatures. They are a part of the Eukaryota or Eukarya group of organisms, one of the three categories of life.
A cell's genetic material is housed in a central chamber that is encircled by membrane and is known as the nucleus. compartments with specific functionalities that are membrane-bound and floating in the cytoplasm.

Compare metamorphic rock and intrusive igneous rock in terms of how and where they form. Then compare sedimentary rock and extrusive igneous rock in terms of how and where they form.
Answer:
Igneous rock are rocks that arise from the formation of magma, as this internal terrestrial magma cools it solidifies (within the crust) forming rocks of different sizes and structures, instead metamorphic rocks are rocks formed by the modification of other pre-existing ones in the interior of the Earth through a process called metamorphism.
On the other hand, sedimentary rock is the rock that is formed by mineral sedimentation, of different minerals of large or small diameter, which compared to igneous extrusive rock, this is the solidification of magma from the earth but in the earth's crust.
Explanation:
Magma is the material that forms rocks initially, but in a liquid state, which is found inside the Earth at extremely high temperatures. When the magma rises to the surface, it cools and solidifies (consolidation) forming igneous rocks that can be internal or external depending on whether they are inside or outside the Earth's crust. On the other hand, there are other processes where rocks are formed, but not initially or primarily, but from other rocks or other minerals such as sedimentation.

How can scientists investigate the impact of limiting factors on a population?
Answer: No population can increase without limitation. Instead, populations in natural ecosystems increase or decrease in response to the changes in the factors that restrict growth. Many factors influence population densities and growth, and these factors may lead to oscillations in population size over time. It is also often difficult to determine the exact factor limiting growth. Many different factors may combine to produce unexpected results.
Explanation: I hope this helps....
Answer:
Limiting factors include a low food supply and lack of space. Limiting factors can lower birth rates, increase death rates, or lead to emigration. Limiting factors determine the carrying capacity of a population.

you think this is limiting? How could this affect scientists search for life beyond Earth?
Answer:
I think there is life beyond earth. Actually there most definently is. I think in a way it could be limiting. It's the fcat that the ones out there may not even be able to receive the message as fast as we please. Who knows, it could be years, decades, maybe centuries before they make actual contact with us. Then again, maybe they already have. But, the way this could affect the study is the fact that (I doubt it) but maybe a message could be sent the wrong way, or they misinterpret it. That's the only think I can get off. Anyway, this can also depend on how much funding is going into space. This also brings up the question, "How much do we know about our own planet?

C) to distribute oxygen throughout the body
D) to create new individuals within the species
Answer:
D
Explanation:
The reproductive system is another word for genital system, which means it would create new species
Answer:
The answer is D
Explanation:
Early during development, organisms as diverse as a human, a mouse, and a bat can appear indistinguishable. All of their embryos look nearly identical,
suggesting that
this is a coincidental resemblance between them
during development, humans go through stages of being a mouse and a bat
these very different species have a shared ancestry with all mammals
similar structures have developed because of convergent evolution

Predict the most likely outcome of culturing transformed E. coli in the presence of tetracycline.Justify your prediction.
Answer:
E.coli is a bacterium which is preffered for transformation due to its rapid growth and high efficiency of introduction of DNA molecules into cells.
Tetracycline is an antibiotic used to treat several infections such as cholera, plague, brucellosis, and malaria etcetra.
Plasmid is a small, extrachromosomal DNA molecule present in cell which is seprated from chromosomal DNA and have ability to replicate independently.
When a plasmid resistant to tetracycline and kanamycine is inserted into E.coli, the process is called transformation. E.coli might not be able to survive due to absence of plasmid but the transformed strains having antibiotic tetracycline and kanamycine will probably be able to survive it.
Hence, the culture of bacteria carrying plasmid will be able to survive only.
Maximum transformation to tetracycline achieved when cells were harvested from L broth at 5.0-6.0 cfu/ml , followed by washing twice in cold.
The susceptibility of E.coli strain to culturing transformation by plasmid DNA was examined and optimized.
TransformationCells grown within the presence of D - cycloserine ( Cyc ) rather than Neg Gram (N x) transformed better. The presence of 5 mm Mg2+ ions in washing and CaCl2 solutions stimulated transformation about 2-fold.
Optimal conditions for transformation included a pH range of seven. 25-7.75 and a cell-to-DNA ratio of about 1.6 . 10(8) cfu/ng plasmid DNA.
The frequency of transformation was highest when cells were exposed to 100 mM CaCl2 in 250 mm.
Composition[tex]\rm KCl + 5 mM \;MgCl2 + 5 mM \;Tris[/tex]
pH 7.6, before mixing with DNA
Therefore, the results of culturing transformed E.coli within the presence of tetracycline is justified.

A scientist is observing an organism under the microscope. The organism was found in salt water, is multicellular, and its cells do not have nuclei. What is most likely true about the organism based on this information?
Answer:
I think the options should be:
It is a protist because it is microscopic.
It is not a protist because its cells do not have nuclei.
It is not a protist because it is multicellular.
It is a protist because it is found in salt water.
If correct, then the answer is option B
Explanation:
The above information about the organism can confirm that the organism is not a protist because it does not possess nuclei. It could be a prokaryote but these are not multicellular but can only be under the condition that maybe each prokaryotic cell aggregates and exist as a colony.
Answer:
the answer is its a protis bc its microscopic .

Explain how your model demonstrated energy transformation from thermal energy to mechanical energy during a volcanic eruption.
(I mixed warm water, vinegar, and baking soda)
Answer:
Well to begin with, the thermal energy is mostly provided by the energy contained in warm water, when mixed with the other two components the chemical units are modified to form a composite solution that will result in an energy release, this energy release generate a movement, which in this case is the eruptive movement simulating the eruption of a volcano.
Explanation:
By mixing the vinegar (which is an acid) with the baking soda (which is a base), they react and transform into water, sodium acetate (a salt), and carbon dioxide (a gas). Carbon dioxide (CO2) is the gas that causes bubbles to form from the eruption of the volcano and balloons to swell.
