Which statements compare meiosis I and meiosis II? Check all that apply.-The parent cell in meiosis I is diploid and has 2n chromosomes. -Meiosis I produces two gametes that have exactly the same genetic make up. -Meiosis II creates four daughter cells that are genetically different from one another. -After meiosis I, two daughter cells with haploid number of sister chromatids are produced. -Four gametes with haploid number of chromosomes and single chromatids result after meiosis II.
after meiosis I two daughter cells with haploid number of sister chromatids are produced.
the parent cell in meiosis I is diploid and has 2n chromosomes.
four gametes with haploid number of chromosomes and single chromatids result after meiosis II.
Meiosis II creates four daughter cells that are genetically different from one another.
After meiosis I, two daughter cells with haploid number of sister chromatids are produced.
Four gametes with haploid number of chromosomes and single chromatids result after meiosis II.
In which range is the peak wavelength of a star that is much hotter than the Sun most likely to be? A) radio waves B) infrared radiation C) microwaves D) ultraviolet light
The range in which the peak wavelength of a star that is much hotter than the Sun most likely to be ultraviolet light. Therefore, option (D) is correct.
What is peak wavelength of star?
The peak wavelength is the wavelength at which a radiation source emits the most energy or has the highest intensity. It is related to the temperature of the source through Wien's law, as hotter sources emit shorter wavelengths of radiation.
The peak wavelength of a star is related to its temperature through Wien's law. Wien's law states that the wavelength of the peak intensity of a blackbody radiation curve is inversely proportional to its temperature. Therefore, hotter stars have shorter peak wavelengths than cooler stars. Since ultraviolet light has shorter wavelengths than visible light, stars that are much hotter than the Sun would have their peak wavelength in the ultraviolet range. Thus, the correct option is D) ultraviolet light.
The plasma membrane is selectively permeable. It allows some substances to enter and leave the cell unrestricted while others are restricted. Some toxins produced by certain bacteria cross the plasma membrane, interfering with normal chemical reactions, and ultimately killing the affected cell. Why are cells unable to stop the flood of these harmful substances into the cell
The cells are not able to stop the flow of the mentioned harmful substances into the cell as they fail to recognize them as foreign entities. These foreign toxins have intracellular targets with which they bind and lead to death of the cell.
Cell death due to foreign toxins:
The plasma membrane is formed of lipids. The toxins produced by the bacterial cells are water soluble. Therefore, they identify particular receptors on the membrane and associate with them. Thus, cell at certain occasions fail to identify them as foreign entities.
They combine with the plasma membrane of the cell and induce pore formation, however, there are many toxins that invade the cell and possess intracellular targets via endocytic vesicles. With the help of these vesicles, they deliver their enzymatic domain into the cytosol and results in the death of the cell by obstructing the metabolism of the cell.
Thus, cells fail to identify the bacterial toxins as foreign entities and they invade the cell and results in cell death.
Find out more information about invasion of foreign toxins here:
There are specific receptors present on the surface of the normal cell membrane to recognize the molecules to allow them to pass or not. Most of the bacterial toxin are water-soluble molecules, and bound to the cell surface and interact with them as some time antibody-antigen interaction or cell recognition does not occur that form a pore in the cell membrane and toxins move into the cell.
Once toxins enter the cell they attack intracellular targets through endocytic vesicles. Ultimately these ends in cell death.

A student studies art and learned that he has several layers including inner and outer cores the student will make a model of the inner and outer cores of earth which model would be most like earths actual inner and outer cores A: A pool of liquid inside a solid metal ball. B: Metal ball with a slightly smaller solid metal ball inside it. C: A solid metal ball in the middle of a pool of liquid. D: A pool of one type of liquid in the middle of a pool of another type of liquid
C: A solid metal ball in the middle of a pool of liquid.
Since the student is studying the earth, the core area is made up of a solid metal ball in the middle of a pool of a liquid.
The core is the inner most part of the earth.
It exists in the middle of the earth.
The core is divide into two layers; inner core and outer core.
The inner core is a solid ball of metal.
The outer core is a liquid metal under high temperature and pressure.
Most compounds that produce this in aqueous solution are ionicA) Acid B)Base C) Both
The correct answer is BOTH
What is muscle memory? What does new research say about muscle memory?
Muscle memory is a form of procedural memory that involves consolidating a specific motor task into memory through repetition, which has been used synonymously with motor learning.
