This happens early in embryonic development in females, where one of the two X-Chromosomes is randomly (and permanently) inactivated, as you said, in cells other than egg cells.
This phenomonon is actually called X-Inactivation.
X-Inactivation make sure that females, just like males, have a single functional copy of the X Chromosome in each and every one of their cells in their body.
Glad I could help, byee now
Answer:
See Explanation
Explanation:
I wont be able to answer your full question due to that I don't know where your home is located.
<h2><u>Question 1</u></h2>
Four possible sources of energy in your home are:
Thermal Energy, like your microwave or oven
Solar Energy, solar panels if you have any
Wind Energy, like a fan blowing
Electrical Energy, like plugging in a device
<h2><u>Question 2</u></h2>
Probably, in our world today, your home would mostly be powered with one of the following:
Solar Energy: If you have solar panels installed. They generate a lot of energy for electricity.
Electrical Energy: Power Plants create electric energy that go through cables to millions of billions of homes. Electrical Energy is most people's main source of power due to electric companies providing it every second.
I will continue on, in order to answer Questions 3 and 4, your location is required.
Hope this helped! :)
Answer:
All of them
Explanation:
The effect may not be real because we don't know if the results are reproducible: Peers can identify flaws in the experimental design because an experiment must have a clear design in order to be reproducible by other researchers or else they would not have scientific validity.
The treatment kills cancer cells, but it might simply be a poison that kills all cells—even normal cells: It is possible that in the design of the experiment carried out only cancer cells were used but it had not been performed in healthy cells, which would imply the possibility that the fungus kills all the cells.
Cell samples were taken from too few patients: This may be another mistake because when only a small sample is analyzed it is not certain if the fungi are the ones that kill the cancer cells or are other conditions of the analyzed patient.
Um. The drawbacks to the extensive use of solar energy? well all the other statements about it are false so the correct answer would have to be B. Necessary equipment and installation are expensive
hope that helped
The answer is A: phytoplankton provides nutrients to consumers in the ecosystem.
Hope this helps:)
