<span>The segregation of alleles occurs during meiosis I or option C "meiosis." M</span>eiosis is<span> a specialized type of cell division that reduces the chromosome number by half. Which is where it separates the twenty-four chromosomes twelve from your Father twelve from your Mother.
Hope this helps!

Answer:
Explanation:
MEIOSIS:
- Each replicated chromosome pairs with its corresponding homologous chromosome
- Tetrads form and crossing over sometimes occur
- Paired homologous chromosome line up across the center of the cell.
- Four haploid daughter cells form that are not identical to the parent cell
MITOSIS:
- Homologous chromosomes do not pair
- One row of chromosomes line up at the center of the cell.
- The cell nucleus divides only once
- Two diploid daughter cells form that are identical to the parent cell.

Answer:
The correct answer is (b) 1%
Explanation:
Represented in an ecological energy pyramid, the seals would be in the third position from the bottom as <em>secondary consumers</em>.
In this example, the <em>base of the pyramid </em>will be represented by the coconut palms, the primary producers, also known as autotrophs, which create their food by <em>taking their energy from non-living sources</em> of energy, like the sun.
The second level consists of primary consumers. Herbivores feed solely on <em>primary producers</em>, in this case, the coconut crabs.
The third level would be the secondary consumers, usually carnivores and omnivores, in this case, the seals.
In this example, as seals would be the secondary consumers located at the third level of the pyramid from the bottom, they will receive about 1% of energy.
I hope it helps!
Transfer = 10/100 of total energy.
<u>Explanation:</u>
Energy and matter is transferred from one organism to another by the process of food chain and food web. In food chain the organism of higher trophic level feeds on the organisms of lower trophic level. On feeding only 10% of the energy gets transferred to the organism of higher trophic level while the rest are being used in the metabolic processes and are produced as heat. This is called as ten percent energy transfer rule.
The mathematical representation of the transfer of energy is given as
Transfer = 10/100 of total energy.
