Answer:
Option B, The parents supplied different alleles
Explanation:
The genotype of any offspring is decided by the equal contribution of allele from both the parents. Hence, even when an organism is heterogyzous it is clear that the allele pair expressing the trait (due to the heterozygous pair) is formed by the contribution of both the parents equally which means one allele is given by one parent while other allele is given by other parent.
For instance -
For any heterozygous allele pair let’s say “Xx” , allele “X” would be donated by one parent while allele “x” would be donated by another parents.
Hence in order to form a heterozygous offspring the two parents need to contribute different alleles.
Therefore, option B is the correct answer
.......is secreted into the bloodstream, whereas _____ is secreted into mucus such as gastrointestinal fluid, colostrum, saliva, tears, and sweat:
a. Monomeric IgM; pentameris IgM
b. Monomeric IgA; dimeric IgA
c. Monomeric IgA; dimeric IgM
d. Dimeric IgA; monomeric IgA
Answer:
b. Monomeric IgA; dimeric IgA
Explanation:
IgA is a class of antibodies that are found mainly in body secretions. In sweat, tears, saliva, mucus, breast milk, and gastrointestinal secretions, IgA is secreted as a monomeric antibody. Smaller quantities of this class of antibodies are also present in blood and lymph. However, IgA is present in a dimeric form in the bloodstream. It makes up 10–15% of all antibodies in the blood. The main function of this class of antibodies is to give localized protection of mucous membranes against bacteria and viruses.

Explanation:
Agricultural practices relating to irrigation have the tendency to reduce the water level of river basins.
<h3>What are the effects of irrigation agriculture on river basins?</h3>
Irrigation agriculture requires that crops are watered artificially and this requires a water source. Hence, waters in river basins suffer and this leads to a reduction in their levels.
Water quality is impacted by agricultural practices such as the use of agrochemicals and fertilizers. Agrochemicals are washed into water bodies and this impacts biodiversity life in water.
One conservation strategy to reduce the impact of this kind of agricultural practice would be to practice organic farming. A farming practice that is devoid of using agrochemicals or the ones that are not poisonous to biodiversity and are biodegradable.
