Examples of the energy pyramid to explain production, distribution, and use of food resources
miss Akunina [59]
The energy pyramid (also called ecological pyramid) quantifies the energy transfer from one organism to another along the food chain. Energy decreases as you move through the levels from the bottom to the top of the pyramid.At the bottom are the p<span>roducers which bring energy from nonliving sources (sun) into the community (photosynthesis).

They eat the primary consumers, which makes them carnivores. And at the top are the </span><span>Tertiary consumers.</span></span>

Do different patterns of electrical signals have unique<br> meanings?
Archy [21]

Answer:

Plants use electric fields to communicate with bees, scientists have learned.

Bumblebees are able to find and decipher weak electric signals emitted by flowers, according to the study.

Tests revealed that bees can distinguish between different floral fields, as if they were petal colours. The electric signals may also let the insects know if another bee has recently visited a flower.

Explanation:

How bees detect the fields is unknown, but the researchers suspect the electrostatic force might make their hair bristle. A similar hair-raising effect is seen when placing one's head close to an old-style TV screen.

Flowers were already known to use bright colours, patterns and enticing scents to attract pollinators.

In roosters, two genes determine the shape of their comb. The R_pp produces a rose comb, rrP_ produces a pea comb. When both gen
oksian1 [2.3K]

The genotype ratio is the proportion of different genotypes observed in the next generation from a genetic cross. The phenotypic ratio is the proportion of phenotypic traits observed from a genetic cross.

In this case, the genetic cross between a rose comb rooster (RRpp) and a pea comb rooster (rrPP) will produce the F1 generation:

  • Parental gametes: Rp; rP
  • Cross: Rp x rP

F1 Generation:

  1. Genotype: 100% RrPp
  2. Phenotype: 100% walnut comb (R_P_)

F1 gametes:

  • 1/4 RP; 1/4 Rp; 1/4 rP; 1/4 rp

Punnett square segregate alleles (F2):

                   1/4 RP             1/4  Rp               1/4 rP              1/4  rp

1/4 RP      1/16 RRPP        1/16 RRPp          1/16 RrPP         1/16 RrPp

1/4 Rp     1/16 RRPp         1/16 RRpp         1/16 RrPp         1/16 Rrpp

1/4 rP       1/16 RrPP          1/16 RrPp          1/16 rrPP          1/16 rrPp

1/4 rp       1/16 RrPp          1/16 Rrpp          1/16 rrPp           1/16 rrpp

Hence, the genotypic and phenotypic ratios in a cross between two F2 will be:

Genotypic ratio F2:

  • 1/16 RRPP
  • 1/8 RRPp
  • 1/16 RRpp
  • 1/8 RrPP
  • 1/4 RrPp
  • 1/8 Rrpp
  • 1/16 rrPP
  • 1/8 rrPp
  • 1/16 rrpp

Phenotypic ratio F2:

  • 9/16 walnut comb (R_P_)
  • 3/16 rose comb (R_pp)
  • 3/16 pea comb (rrP_)
  • 1/16 single comb (rrpp)
