Wood has <u>"potential"</u> energy while a burning fire has <u>"kinetic"</u> energy.


Potential energy is characterized as a put away vitality, while dynamic energy is found in movement. Kinetic energy can be seen on numerous scales, regardless of whether it's the vibrating of particles creating heat, or long wavelength radio waves. When taking a gander at energy it is critical to take a gander at the law of conservation of energy . This physics law expresses that vitality can't be made nor devastated, however can just change starting with one shape then onto the next (i.e. abandoning potential energy to kinetic energy ). On account of consuming wood, put away potential energy in the log is discharged because of warming by other energized molecules. This compound response is called combustion and requires oxygen.

How do human beings negatively affect the carbon cycle?
andre [41]

Answer:

Human activities have a tremendous impact on the carbon cycle. Burning fossil fuels, changing land use, and using limestone to make concrete all transfer significant quantities of carbon into the atmosphere. ... This extra carbon dioxide is lowering the ocean's pH, through a process called ocean acidification.

In cucumbers, dull fruit (D) is dominant over glossy (d) fruit, orange friut (R) is dominant over cream fruit (r), and bitter co
stiv31 [10]

Explanation:

  • Dull fruit (D) is dominant over glossy (d) fruit.
  • Orange friut (R) is dominant over cream fruit (r).
  • Bitter cotyledon (B) is dominant over non-bitter cotyledons (b).

The three genes are independent.

<h3>a)</h3>
  • A plant homozygous for dull, orange fruit and bitter cotyledons has the genotype <em>DDRRBB</em><em>.</em>
  • A plant homozygous for glossy, cream fruit and non-bitter cotyledons has the genotype <em>ddrrbb</em>.

100% of the F1 will have dull, orange fruit and bitter cotyledons and will be heterozygous for all genes: <em>DdRrBb</em>.

<u>The F2 will have 8 possible phenotypes:</u>

  • 27 D_R_B dull, orange fruit and bitter cotyledons
  • 9 D_R_bb dull, orange fruit and non-bitter cotyledons
  • 9 D_rrB_ dull, cream fruit and bitter cotyledons
  • 3 D_rrbb dull, cream fruit and non-bitter cotyledons
  • 9 ddR_B_ glossy, orange fruit and bitter cotyledons
  • 3 ddR_bb glossy, orange fruit and non-bitter cotyledons
  • 3 ddrrB_ glossy, cream fruit and bitter cotyledons
  • 1 ddrrbb  glossy, cream fruit and non-bitter cotyledons

<h3>b)</h3>

An F1 plant is crossed with a plant that has glossy, cream fruit and non-bitter cotyledons.

<h3>DdRrBb x ddrrbb </h3>

The F1 individual can produce 8 types of gametes: DRB, DRb, DrB, Drb, dRB, dRb, drB and drb. The cream fruit and non-bitter cotyledons individual can only produce drb gametes. This cross also produces a progeny with the following genotypes and phenotypic proportions:

  • 8 DdRrBb dull, orange fruit and bitter cotyledons
  • 8 DdRrbb dull, orange fruit and non-bitter cotyledons
  • 8 DdrrBb dull, cream fruit and bitter cotyledons
  • 8 Ddrrbb dull, cream fruit and non-bitter cotyledons
  • 8 ddRrBb glossy, orange fruit and bitter cotyledons
  • 8 ddRrbb glossy, orange fruit and non-bitter cotyledons
  • 8 ddrrBb glossy, cream fruit and bitter cotyledons
  • 8 ddrrbb  glossy, cream fruit and non-bitter cotyledons
