Answer: c. In special sense organs.
Explanation:
Bipolar neurons are those neurons that have two cytoplasmic extensions attached particularly to the cell body. These neurons are found in the sense organs like retina of eye, nasal cavity roof, also in the inner ear. Thus helps in receiving the stimuli of olfaction, vision, and hearing.
lungs or ribs that separate the two upper chambers from each other
<u>ANSWER:</u>
The correct order is- Zygote, Blastula, Gastrula, Fetus.
<u>EXPLANATION:</u>
- The embryo develops from the zygote which is formed when the gametes fuse in the process of "fertilization".
- The zygote undergoes cell division to form blastula which is a "ball of cells".
- Gastrula leads to the rearrangement of cells of the blastula into three layers that differentiate into different systems of organ.
- The last stage is the fetus which then develops into a baby.
Answer:
Sinoatrial Node?
Explanation:
Blood pressure drops whenever the vagus nerge is stimulated. In fact, babies have to constantly be monitored for position, becase cranial pressure can stimualte the vagus nerve and cut heart circulation by inhibitng the Sinoatrial node.
Answer:
The correct answer is - inactivity of genes.
Explanation:
DNA methylation is a process in which the DNA molecule is attached to the methyl groups. Methylation affects the activity of the segment of DNA without modifying or changing the sequence of the gene.
If methylation takes place within the promoter region of the gene, DNA acts as a represser for the process of gene transcription. Inactivity of the gene is by the help of methylation in the eukaryotes is to control the gene expression.
Thus, the correct answer is - inactivity of genes.
