Answer:
Energy is said to flow in a "one-way stream" through an ecosystem. In your own words, describe what that means. Energy is not recycled. Energy enters an ecosystem and flows through a food chain, but it is not reused, it is lost as heat.
Hope the answer helps:)
Answer:
8 chromosomes
Explanation:
Diploid state is when an organism have two set of chromosomes (2n) i.e. combination of two haploid (n) gametes containing one set of chromosome each. Sexually reproducing organisms whose somatic or body cells are diploid (2n) undergo meiosis to produce gametes or sex cells with haploid number (n).
Therefore, in the newly discovered Biologica terificia species of snail, if the haploid state (n) of their gametes is 4, then their diploid (2n) somatic cells must be 4 × 2 = 8.
The question specifies the chromosomal number at the G1 phase of Interphase. At this stage, the cell is preparing to undergo division by increasing in size and duplicating its organnelles but not yet its genetic material which is not until the next phase called S-phase. Hence, the chromosome number of somatic cells remain 8 at the G1 phase.
Renewable energy provides reliable power supplies and fuel diversification, which enhance energy security and lower risk of fuel spills while reducing the need for imported fuels. Renewable energy also helps conserve the nation's natural resources.

Answer:
1/4
Explanation:
Given that the F2 cross produces offspring according to the expected 9:3:3:1 ratio.
YyRr X YyRr:
Let us break the dihybrid cross into individual monohybrid crosses.
Yy X Yy :
Y y
Y YY Yy
y Yy yy
2/4 or 1/2 of the offspring are heterozygous for the trait.
Similarly, in Rr X Rr cross, 1/2 of the offspring are heterozygous for the trait.
Together, 1/2 * 1/2 = 1/4 of F2 plants are expected to be heterozygous for both traits.
