what will be the result if a eukaryotic cell completes mitosis but does not undergo cytokinesis?
Answers
A cell that completed mitosis but does not undergo cytokinesis PRODUCES one cell with two nuclei, each identical to the nucleus of the parent cell. Cytokinesis is the last phase of cell division.
Cytokinesis is the process by which a parental cell divides its cytoplasm to produce two genetically identical daughter cells, each one containing one cell nucleus.
Cytokinesis occurs in both types of cell division, i.e., mitosis and meiosis.
In animal cells, cytokinesis occurs by the emergence of a contractile ring that appears just beneath the cell membrane.

What is Bacteria?Bacteria are defined as tiny, single-celled organisms that are millions of different types of bacteria. Many can be found in and on the body and are beneficial to us. Bacteria lack a membrane-bound nucleus and other internal structures, so they are classified as unicellular life-forms called prokaryotes.
The bacteria in our bodies help break down the food we eat, provide us with nutrients and neutralize toxins that play an essential role in preventing infection by protecting colonized surfaces from invading pathogens.

Explanation:
Water molecules moving across the plasma membrane until solute concentrations are equal on both sides of the membrane best describes the process of osmosis in an animal cell .
Osmosis is the process in which molecules move from a region of higher concentration to that of a lower concentration across a semi-permeable membrane.
Osmosis provides a balance between the elements in which organisms are exposed to. A very high concentration may cause cells to shrink and die hence the reason to maintain a balance for optimal functions and survival.

Tại sao con người chúng ta lại sốt nhiều lần như vậy?
Answers
Answer:
Fever is an elevated temperature of the human body that is substantially beyond the normal range. Normal body temperature fluctuates daily from about one degree below 98.6 degrees Fahrenheit to one degree above that number. Lower body temperatures usually occur before dawn; higher temperatures in the afternoon.
Body temperature also varies slightly depending on where on the human body it is measured. Rectal (internal) temperature tends normally to be higher than skin (surface) temperature. Oral and armpit temperatures can approximate actual body temperature and are more convenient to measure.

Explain how kinetic energy affects each object as it changes its state of matter:
A) Water boiling:
B) Popsicle freezing:
C) Water condensing on the side of a water bottle:
Answers
Answer:
Explain how kinetic energy affects each object as it changes its state of matter:
A) Water boiling:
B) Popsicle freezing:
C) Water condensing on the side of a water bottle:
Explanation:
A) A water boiling will result in evaporation, therefore the particles will move extensively faster than liquid due to it being vapor.
B) A popsicle freezing is originally a solid so it'll have the least amount of kinetic energy as the particles remain fairly slow.
C) Due to the fact that water is condensing, while turning into a liquid. The water condensing on the side of the water bottle would produce a lower kinetic energy level due to the fact that it's becoming a liquid. Though liquids have higher kinetic energy than solids, as gases have a higher kinetic energy compared to liquids.
Evaporation from boiling water causes the particles to move much more quickly than they would in a liquid state.
What is Kinetic energy?A popsicle is initially a solid, it will have the least kinetic energy because the particles are still moving slowly. Because water is condensing as it transforms into a liquid.
Because it is turning into a liquid, the water that is condensing on the water bottle's side would have less kinetic energy.
Gases have a higher kinetic energy than liquids, despite the fact that liquids have a higher kinetic energy than solids.
Therefore, Evaporation from boiling water causes the particles to move much more quickly than they would in a liquid state.

Explanation:
This happened through a lateral transfer of genes.
We can arrive at this answer because:
Lateral gene transfer is a system for exchanging genetic material between unrelated bacteria.Bacteria are beings that reproduce without the exchange of genetic material, but in some cases, this can be done with the lateral transmission of genes.This transmission can be done through the process of conjugation, translation, or transformation.The result is that new bacteria are created with a mixture of genes from two unrelated bacteria.
