Answer:
Many farmers use chemical herbicides to kill weeds and
insecticides to kill insects. Using genetic engineering, scientists
have developed ways to resist harmful crop pests. In this Gizmo,
you will use genetic engineering techniques to create genetically
modified corn.

Answer:
(2⁵)²: 1024 combinations
Explanation:
In this case, the chromosome haploid number (n) of the target species is equal to 10, and therefore its diploid number (2n) is equal to 5 (i.e., somatic cells in the target species contain 5 pairs of chromosomes). That means that one individual can produce 2⁵ or 32 different gametic combinations. Moreover, the number of possible combinations that emerge from paring different gametes (sexual reproduction) can be calculated as (32)² = 1024 combinations.
Answer:
A. Biodiversity will decrease .
Explanation:
- The loss of a keystone species can cause extinction or mass destruction of other species that are dependent on it because keystone species are those species which significantly influence the existence and survival of other species in an ecosystem
- Since, beavers are considered as the keystone species, their removal from the ecosystem will cause loss of many other species in the ecosystem resulting in Decrease in the biodiversity of that ecosystem.
Structurally, DNA and RNA are nearly identical. As mentioned earlier, however, there are three fundamental differences that account for the very different functions of the two molecules. RNA has a ribose sugar instead of a deoxyribose sugar like DNA. RNA nucleotides have a uracil base instead of thymine.
