Answer:

E) 2

Explanation:

The energy transfer through the food chain is not 100% from one consumer to another, or from the producer to the primary consumer, but instead it is around 10%. This means that if a producer has the 100% of energy, as it is the one that produces it, the primary consumer will only get 10% of its energy while consuming it, while the predator of the the primary consumer will only 10% from the primary consumer, or rather only 1% from the energy of the producer. In this case we have 200 kg of plant material. The plant material represents a producer, thus it is the one with 100% of energy. A herbivore will eat the plant material, getting 10% of its energy, thus this plant material is supporting about 20 kg of herbivore. The predator of the herbivore gets only 10% from the herbivore's energy, or only 1% of the producer's energy, thus only 2 kg of predator can be supported by the initial plant material.

1. If the frequency of two alleles in a gene pool is 90% A and 10% a, what is the frequency of individuals in the population wit
Illusion [34]

Answer: 0.18

Explanation:

For the alleles, the percentage distribution of each is 'A' (90% = 0.9)

While 'a' (10% = 0.1)

Hence, 0.9 and 0.1 are the respective frequencies of each allele

Now, apply Hardy-Weinberg Equilibrium equation, where heterozygotes are represented by the 2pq term.

Therefore, the number of heterozygous individuals (Aa) is equal to 2pq which equals

2 × 0.9 × 0.1 = 0.18

Thus, the frequency of heterozygote is 0.18, while the percentage distribution in the population is 18%

Which form of reproduction would be most beneficial in an unstable environment?
Sliva [168]
Sexual reproduction would help the most because the offspring are genetically varied more than other types of reproduction and are more likely to adapt and survive.
