Answer:
D. Sterility Locus
Explanation:
Angiosperms have several mechanisms to prevent self-pollination due to the advantage of cross-pollination. One of such mechanisms is self-incompatibility genes present on the sterility locus.
These genes determine the germination of the pollen on the stigma. If both the pollen and stigma carry the same allele of the gene present at the sterility locus, the germination of pollen is prevented.
The sterility locus has multiple alleles and the presence of the same alleles at the same locus in both pollen and stigma prevents the pollen germination.
For example, pollen from S1S2 individuals can not germinate on the stigma with the S1S3 genotype. Here, the pollen does not obtain water as required for germination from the stigma and are unable to germinate.
They would have Severe Abdominal pain. These are the symptoms leading to that occur.<span>If diarrhea is accompanied by fever, malaise, or abdominal pain, contact the prescriber immediately because of the possibility of excessive fluid and electrolyte loss. Dehydration and electrolyte loss occur very rapidly in the pediatric patient because of the patient's size and sensitivity to loss of fluid volume and electrolytes through the stool. Immediately report to the prescriber any abdominal distention, firm abdomen, painful abdomen, or worsening of or lack of improvement in diarrhea 24 to 48 hours after medication administration. If symptoms persist or dehydration occurs (e.g., no tears and decreased urine output in the child), contact the prescriber. If the patient is sluggish, lethargic, or confused or the diarrhea is bloody, contact the prescriber immediately or go to the closest emergency facility. hope that helped</span>
Answer:
The last one. Plants make more sugar on sunny days than on cloudy days
Explanation:
<span>Both pine trees and ferns have the ability to make their own food via photosynthesis. They are both able to convert water and carbon dioxide into oxygen and sugars. Based on the concept of domains they are both classified under Eukaryota. </span>
The water is warmed up by the sun and then it evaporates into the atmosphere. The sunlight warms the water by its heat.
Water is then cooled down and condensation takes place.
The water then finally returns back to the earth by the process of precipitation in the form of rain or ice.
Water and nutrients that are not recycled on earth are stored in the form of reservoirs.
