The water would rush into the cell and the cell will explode.
Autotrophs obtain energy and nutrients from sun and inorganic substances
The answer should be C, progesterone.
Progesterone is the hormone which can help maintain the lining of uterus and to further thicken it so that the uterus is prepared for implantation and the development of a baby. The level of progesterone is significantly rose after ovulation.
On the other hand, LH, luteinising hormone, is produced by oestrogen, another female hormone which will drop after ovulation. LH helps stimulate ovulation and prevent the development of other follicles, the origin of eggs, to form yellow body instead. Which yellow body is the one which stimulates the production of progesterone.
Last but not least, I believe D should be testosterone, and it is a male hormone so it will not be found in female normally.
Therefore, your answer should be C, progesterone.
Answer:
D) presence of transcription activators or repressors
Explanation:
The reason why this is not post-transcriptional regulation is that activators actually start the process of transcription by binding to specific sites. while on contrary when repressor binds it halt the process.
For example, there is a protein called CAP which in the presence of cAMP bind with promoter region and enhances the activity of RNA polymerase . While in the absence of cAMP it can not bind to promoter hence the transcription stooped.
