Answer:
7
Explanation:
Mechanical advantage is given by the ratio of the distance of the fulcrum from the two objects of the system.
Here the boulder is from the fulcrum and the mass at the other end of the lever is from the fulcrum.
So, mechanical advantage is given by
So, mechanical advantage of the board is 7.

Answer:
The two genes are linked together
Explanation:
<em>The conclusion that can be drawn about the arrangement of the genes on the chromosome in the Aa Bb parent is that the two genes are linked together. That is, they do not assort independently.</em>
When two genes are linked together, the number of recombinant offspring would be more than the number of offspring with parental traits. The frequency of recombination would also not exceed 50%.
<em>Recombination frequency = number of recombinant offspring/total number of offspring x 100%</em>
Number of recombinant offspring = 45 + 45 = 90
Total number of offspring = 45 + 45 + 5 + 5 = 100
Recombination frequency = 90/100 x 100% = 10%
Hence, the two genes Aa and Bb are said to be linked together.
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.
