Explanation:
Thin air exerts less pressure than air at a lower altitude.
True the plate margins are what I like to picture as train tracks and horizontal moves are the train. Pls mark me as brainliest.
Answer:
A. S phase
Explanation:
The cell cycle involves all the series of division events that occurs to an organism. Cell division, which can be meiosis or mitosis, involves two main stages viz: Interphase and M phase.
Interphase describes the resting stage of the cell i.e. when the cell is not dividing. The cell uses this time to prepare itself for the next round of division. Interphase stage further consists of three main phases viz: G1, S and G2 phases.
In the S phase or synthesis phase of Interphase, the cell duplicates its genetic material (DNA). Hence, an onion cell observed by a student to have loosely coiled chromatin depicting DNA duplication is in the S-PHASE.
It is located At the umbilicus
At 20 weeks' gestation, the fundus can be palpated at the
umbilicus. A fundus of 12 weeks' gestation is palpated at the symphysis pubis.
At 16 weeks' gestation, the fundus is midway between the symphysis pubis and
umbilicus. At 36 weeks' gestation, the fundus can be palpated just below the
ensiform cartilage.
