Answer:
In the question it is given that the milkweed with clothianidin above the 1ppb concentration will result in less successful hatching of monarch butterfly eggs. Along with the data from the experiments, the exposure of clothianidin on the monarch habitats will lead to a decrease in the population of the monarch butterfly initially. Then in later generations if any mutation occurs and a resistant butterfly is developed then the population of the monarch butterfly will recover. But without this mutation the population size will be reduced and the size and weight of the butterfly will also get reduced.
Explanation:
When infected by a virus, a host cell produce many thousands of identical copies of the original virus. so the answer is B

Answer:
1128.
Explanation:
The dominant taster phenotype is 1482.
The recessive taster phenotype = 2400 – 1482 = 918
.
Recessive phenotypes = 2400 – 1482 = 918
The recessive phenotype frequency = q² = 918 / 2400 = 0.38.
the recessive allele frequency q = √0.38 = 0.62.
The dominant allele frequency, p = 1-q = 1- 0.62 = 0.38
The heterozygous frequency = 2pq = 2 ×0.38 × 0.62 = 0.47
.
The heterozygous individual in the population = 0.47 × 2400 = 1128.
Thus, the answer is 1128.
Answer:
Animals in Namibia are organized by their conservation in different zones of this place.
Explanation:
The huge diversity in Namibia’s eco system made it the richest place of South Africa in terms of species that this place have. This ecosystem has endemic species with a number of 14 in it.
To organise these species three biotic sectors in Namibia are utilized, they are- The Southern Savanna, the Southwest Arid and Dessert of Namib.
The wetland ecosystem of Arid is important for many species and the mammals also. The elephant of desert and the black rhinos belongs to the Namibia Dessert ecosystem.
