Gregor Mendel used pea plants that were heterozygous for each of two traits—seed color and seed shape—to generate a dihybrid cro

ss. The phenotypic ratio of the resulting offspring was nine with round and yellow seeds, three with round and green seeds, three with wrinkled and yellow seeds, and one with wrinkled and green seeds. From these results, what could Mendel conclude?
a)Traits are inherited as pairs, sets, or groups.
b)Traits that are dominant mask traits that are recessive.
c)Gametes carry one allele for each trait.
d)Traits are passed independently of one another.

Answer: The correct answer is D) Traits are passed independently of one another.

Dihybrid cross is a genetic cross for two traits ( like color and shape of the seed). The main purpose of the dihybrid cross that was performed by Mendel was to determine relationship between different pairs of alleles.

When he performed the dihybrid croos, he got the phenotypic ratio 9:3:3:1 corresponding to nine with round and yellow seeds, three with round and green seeds, three with wrinkled and yellow seeds, and one with wrinkled and green seeds.

This elucidated the law of independent assortment. According to this law, alleles of one gene are separated independent of the alleles of another gene during gamete formation. In other words, traits are transmitted to the offsprings independently.

Thus, D) is the right answer.

Explanation:

Respiration in the mitochondria utilizes oxygen for the production of ATP in the Krebs’ or Citric acid cycle via the oxidization of pyruvate          (through the process of glycolysis in the cytoplasm).

overall: C6H12O6 (glucose) + 6 O2 → 6 CO2 + 6 H2O + ≈38 ATP

Further Explanation:

In all eukaryotic cells, mitochondria are small cellular organelles bound by membranes, these make most of the chemical energy required for powering the biochemical reactions within the cell. This chemical energy is stored within the molecule ATP which is produced.

Oxidative phosphorylation follows; this is a process in which the NADH and FADH2 made in previous steps of respiration process give up electrons in the electron transport chain these are converted it to their previous forms, NADH+ and FAD. Electrons continue to move down the chain the energy they release is used in pumping protons out of the matrix of the mitochondria.

This forms a gradient where there is a differential in the number of protons on either side of the membrane the protons flow or re-enter the matrix through the enzyme ATP synthase, which makes the energy storage molecules of ATP from the reduction of ADP. At the end of the electron transport, three molecules of oxygen accept electrons and protons to form molecules of water...

  • Glycolysis: occurs in the cytoplasm. 2 molecules of ATP are used to cleave glucose into 2 pyruvates, 4 ATP and 2 electron carrying NADH molecules. (2 ATP are utilized for a net ATP of 2)
  • The Citric acid or Kreb's cycle: in the mitochondrial matrix- 6 molecules of CO2 are produced by combining oxygen and the carbon within pyruvate, 2 ATP oxygen molecules, 8 NADH and 2 FADH2.
  • The electron transport chain, ETC: in the inner mitochondrial membrane, 34 ATP, electrons combine with H+ split from 10 NADH, 4 FADH2, renewing the number of electron acceptors and 3 oxygen; this forms 6 H2O, 10 NAD+, 4 FAD.

Un gas puede condensarse al disminuir su temperatura?
myrzilka [38]

Answer:

Si.

Explicación:

Sí, un gas se puede condensar cuando su temperatura disminuye porque cuando la temperatura del área circundante del gas disminuye, se produce una condensación que cambia el estado de la materia i. mi. de gas a estado líquido. La principal razón de esta condensación es la aproximación de moléculas de gas que están muy alejadas unas de otras. Con una temperatura más baja, el volumen disminuye y las moléculas de gas se combinan para formar un líquido.

two pea plant with yellow peas are crossed most of their offspring have yellow peas but about 25% of the offspring have green pe
Mrac [35]

Answer:

Both parents have the genes for yellow peas and green peas

Explanation:

If a plant has inherited one yellow peas gene and one green peas gene, the plant will produce yellow peas because (as you mentioned) yellow peas are dominant. that means the parents are heterozygous (Cc). If both parents have the gene versions Cc, then there is a 25% chance the offspring would get the gene version cc, coding for green peas.
