Answer:

the average percentage of energy lost as heat

Explanation:

An energy pyramid (also called trophic pyramid) is a graphical representation that exhibits how energy flows at each trophic level in a particular ecosystem. In an energy pyramid, it is possible to determine how much energy is available at each trophic level and how energy flows from producers (e.g., photosynthetic plants) to primary consumers (e.g., herbivores), then from primary consumers to the next trophic level (e.g., carnivores), and so successively to all major trophic groups (e.g., higher carnivores). During this chain, energy is lost as heat when it is transferred to the next level, and the average percentage of energy lost increases at each trophic level, thereby less and less energy is available to major trophic groups.

Irina18 [472]

Answer:

e. Red segregated from brown in meiosis I, and straight segregated from curled in meiosis I.

Explanation:

A cross between two flies heterozygous for both genes produced an offspring with the phenotypic ratio of 9:3:3:1. This ratio is expected according to Mendel's law of independent assortment, which states that alleles of the same gene assort independently during gamete formation.

Before meiosis starts in flies, a single diploid cell duplicates its DNA, so each chromosome has 2 sister chromatids that contain the same information.

During meiosis I, the homologous chromosomes separate into two daughter cells. The chromosome number is reduced by half, but each chromosome has two sister chromatids.
During meiosis II, the sister chromatids separate and each daughter cell from meiosis I divides into two new daughter cells (to get the total of 4 haploid cells).

In a heterozygous fly, each homologous chromosome contains a different allele, and the sister chromatids are copies that carry the same allele. For that reason, both traits were segregated during meiosis I.
