<h2>
Why is the Earth not getting larger if the sea floor is slowly spreading?</h2>
Mainly due to the Atlantic experiencing seabed expansion. The sea bottom is subducting, or moving underground, in the Pacific. This is how the Earth's tectonic plates and geological activities function. The top side of the mantle travels to the bottom at one end and to the top at the other, similar to a conveyor belt. This explains why there are volcanoes, why continents drift, and why our planet's surface is continually changing over the span of millions of years.
Therefore, the planet is not getting bigger because its surface is constantly recycling itself.
Answer:
Option A, 152
Explanation:
One glucose molecule undergoes the following three process in one complete chain of aerobic cell respiration -
a) Glycolysis - 2 ATP molecules are produced
b) Kerb cycle - 2 ATP molecules are produced
c) Electron transport chain - 34 ATP molecules are produced
Hence one glucose molecule can produce 38 ATP molecule
Therefore 4 glucose molecule produce
ATP molecules
Hence, option A is correct.
Glass because thats the only transparent one
Yes, an amniocentesis is necessary.
While both the woman and the husband may not exhibit sickle cell anemia, they could be carriers of the sickle cell recessive gene. If she is heterozygous for sickle cell allele, because of her father, and the man has no recessive gene, then the child has no chance of exhibiting the disease but has a 0.5 chance of being a carrier.
However, if the man is also a carrier, the child has a 0.25 probability of having sickle cell anemia.
