The result of this would greatly depend on the genotype of the parents. If either the father is homozygous Type A and the mother is homozygous Type B, then yes, a mix up has occurred because the probability of having an offspring with the blood type O would be zero. But if both of them are heterozygous, then having a child with type O will be possible with a 25% probability.
If no already clean water source are there then filtering technology can make new clean sources of water.<span />
Answer:
Other scientists would need to confirm the results by performing the same experiment.
Explanation:
According to this question, an experiment was conducted by an associate professor, using 20kids, to discover why children are better at problem-solving after exercise. He arrived at a result that Children who exercised showed a 5% increase in the P3 waves, which occur during decision- making.
However, in order for this findings by Charles Hillman to be generally accepted and recognized in the scientific community, which is a connection of several scientists, the results need to be confirmed by performing the same tests or experiment.
Note that, an experiment becomes a scientific theory if it has undergone series of repeatable tests. One of the key features of scientific experiment is that it must be repeatable.
Answer:
Grunion (Leuresthes tenuis): life begins at high tide. During summer and spring, thousands of these fish swim up onto sandy beaches (carried in by high tide). This is called a grunion run, and it occurs ta night during the new moon and full moon when the tide is highest. The females wiggle into the sand and lay thousands of eggs as the males deposit sperm around them. Afterward, they are swept back into the sea. The spawning is timed so exactly that it occurs only on the second, third, and fourth days that follow a new or full moon. After the grunion eggs are fertilized, they incubate for two weeks until the next new or full moon occurs.
Horseshoe Crab (Limulus polyphemus): during late May and early June, vast numbers of horseshoe crabs come together in shallow bays, marshes, and inlets along the Atlantic and Gulf coasts, waiting to come up on the beaches to spawn. The signal to begin is provided by the moon. During the new and full moons, when tide is highest, the crabs come ashore. The female produces a cluster of tiny eggs on her abdomen, and the eggs are fertilized by the male's sperm, and then deposited out in the sand by the female. The next two weeks, the eggs incubate until they hatch during the next full or new moon. When the high water reaches the eggs, they hatch and go out into the ocean.

The practice of leaving crop residues on the field in between planting seasons is known as conservation tillage.
<h3>Conservation tillage</h3>
Some soils are prone to erosion once they are directly exposed to the impact of precipitation.
After harvesting crops from a field, the crop residues are left on the field to prevent the direct impact of precipitation in cause erosion. The crop residue, in addition, adds to the organic matter of the soil after their decomposition.
Such a practice is known as conservation tillage.
