You would expect 25 Kcal of energy stored in trophic level 4.
<u>Explanation:</u>
Energy flow in the ecosystem follows 10% law according to which 10% of the energy in the lower trophic level is transferred to the next trophic level.
In this example grass belongs to the first trophic level, producers.
Energy of grass=25000Kcal
Energy transferred to trophic level 2=10% of 25000=2500
10% of the energy in trophic level 2 is transferred to trophic level 3.
Hence energy at trophic level 3=10% of 2500=250Kcal
Energy transferred to trophic level 4=10% of energy in trophic level 3
=10% of 250=25Kcal
Energy to be stored in trophic level 4=25Kcal
Answer:
<h2>2)</h2>
Explanation:
given
In pea plants, flower color is determined by different genes,
allel P= purple;
allele p= red;
allele L= long;
allele l= round
P is dominant on p and L is dominant on l.
Parents are as given;
PpLl crossed with ppll
F1 generation are;
PpLl, Ppll, ppLl and ppll,
as given Purple, long ( PpLl)= 47;
Red, round ( rrll )= 47;
Purle, round ( Ppll )=3;
Red, long ( ppLl)= 3
Purple, long and Red, round each are 47 in number, their genotype are same as parental genotype, so genes P and L are close together on the same pair of homologous chromosomes.
You kidneys can’t process that amount of water. You could die of dehydration as you will become thirsty.

a
) Anaphase usually ensures that each daughter cell has the same number of chromosomes as the parent cell.
Explanation:
- <em>Mitosis</em>: After DNI duplication and condensation, Sister chromatids of the chromosome, are held together in the equatorial plane until they reach the <em>Anaphase</em>, during which certain enzymes are activated to break the bonds among them and the <em>separation of the chromatids occur</em>, migrating to the opposite poles.
- <em>Meiosis</em>: Gamete formation involves the random and independent segregation of the alleles. After crossing-over, homologous chromosomes which are located in the equatorial plane, get separated. During <em>anaphase I</em> occur the independent <em>separation of homologous chromosomes</em> that migrate to opposite poles of the cell. This separation generates different chromosomal combinations in the daughter cells. There are two alternatives per homologous pair. During <em>Anaphase II</em>, enzymes are activated to break the bonds that keep together the chromosome and <em>separate the sister chromatids</em>.
Anaphase (Mitosis) and Anaphase II (Meiosis) are very similar. By separating sister chromatids, anaphase is responsible that each daughter cell has the same number of chromosomes as the parent cell. Some mutations or alterations in the chromatids migration process might occur during anaphase, such as non-disjunction, which is a defect or mistake in the separation of the homologous chromosomes during anaphase of the meiotic division.
