Answer:
Explanation:
In Vietnam, 34.8 percent of land is dedicated to Agricultural use. In 2018, agriculture, forestry and fishing accounted for 14.68 percent of the country's GDP. Vietnam's main agricultural crops are rice, cassava, maize and sweet potatoes. The relaxation of the state monopoly on rice exports transformed the country into the world's second or third largest rice exporter. Other cash crops produced and exported are coffee, cotton, peanuts, rubber, sugarcane, and tea.
Land dedicated to agricultural use in Bangladesh is 70.1 percent. Agriculture is the largest employment sector in Bangladesh. Most Bangladeshis earn their living from agriculture. Although rice and jute are the primary crops, wheat is assuming greater importance. Tea is grown in the northeast. Because of Bangladesh's fertile soil and normally ample water supply, rice can be grown and harvested three times a year in many areas.

Answer:
Mrs. Ritter, whose blood type is B (Bi) is right in claiming that Ian - blood type A (Ai)- is the father of her baby, with blood type O (ii). Ex-boyfriend AB (AB) cannot be the father.
Explanation:
The blood type, according to the ABO system, is determined by the presence or absence of surface antigens A and B. In addition, genotypes can be co-dominant, in the case of A, B and AB, heterozygous (Ai or Bi) and recessive, in the case of group O (ii)
- <em>
</em><u><em>Type A</em></u><em> contains the antigen A and its genotype can be AA or Ai.
</em>
- <u><em>Type B</em></u><em> contains the antigen B, whose genotype can be BB or Bi.
</em>
- <u><em>Type AB</em></u><em> contains both antigens and a single genotype expression AB.
</em>
- <u><em>Type O</em></u><em> blood lacks surface antigens, its genotypic expression being ii.</em>
According to this, to check if Mrs Ritter's baby is Ian's child, a crossing can be done:
♂ Ai
♀ Bi
Alleles A i
B AB Bi
i Ai ii
<u>Ian and Mrs Ritter have a 25% chance of having a child with blood type O (ii), so the baby may be Ian's child</u>.
To find out why the ex-boyfriend can't be the father
♂ AB
♀ Bi
Alleles A B
B AB BB
i Ai Bi
It is not possible that Mrs. Ritter's ex-boyfriend is the father of the baby, as the possible offspring in the crossover are A, B or AB.
