Answer:
All the above are true.
Explanation:
When a pregnant woman absorbs a few cells from her fetus or fetus absorbs a few cells from its mother, those cells may remain in a mother's or the child's body. This condition is called microchimerism.
Microchimerism is relatively uncommon and cause only 1% of intersex condition. It may also be results from two embryos fusing together during early stage of gestation. The crossing over of stem cells between XX mothers and XY foetus happens during microchimerism.

Question 24: Which of the following statements is true about transcription? Group of answer choices a. In both prokaryotic and eukaryotic cells, transcription requires a promoter b. In eukaryotic cells, orientation and positioning of the polymerase is determined by sigma c. All transcription initiates in the cytoplasm d. In prokaryotic cells, orientation and positioning of the polymerase is determined by TBP and TFII-like transcription factors Question 25: If the transcribed mRNA using this coding strand were to be translated, the...

Question 13 (1 point) Which of the following statements about abatement subsidies is NOT true? Environmental groups dislike abatement subsidies because they appear to reward polluters. Governments like abatement subsidies because they are relatively inexpensive to implement. Abatement subsidies are popular with firms.

Question 1 Which of the following statements is true? Promoter bashing can lead to increased DNA methylation. Methyl groups are removed from the DNA by DNA methyltransferase. ODNA methylation is directly passed on during meisos to all daughter cells. Monoallelic gene expression occurs when a mutation results in dominant gene expression. Patterns of DNA methylation are preserved in somatic cells following mitosis.

Question 78 Which of the following statements about the cytoskeleton is TRUE? All eukaryotic cells have actin, microtubules, and intermediate filaments in their cytoplasm The cytoskeleton provides a rigid and unchangeable structure important for the shape of the cell. The three cytoskeletal filaments perform distinct tasks in the cell and act completely independently of one another Actin filaments and microtubules have an inherent polarity, with a plus end that grows more quickly than the minus end С.
