Answer:

Exergonic reaction

Explanation:

  • A chemical reaction which is associated with a release of energy and thus, is associated with a negative free energy change is said to be an exergonic reaction.
  • An exergonic reaction owing to the negative free energy change is a spontaneous reaction.
  • The energy that is released in the exergonic reaction is usually observed  in the form of heat and light.
  • The energy is released due to the breaking of the chemical bonds.
  • Therefore, on burning of the firewood the bonds between the glucose molecules break up which leads to the release of energy in the form of heat and light and this is thus, an example of an exergonic reaction.

What role does oxygen play in a plants life?
aleksandrvk [35]
Plants need oxygen to survive , no oxygen mean the plant will diePlants do need oxygen to survive. They respire (take in oxygen, give off carbon dioxide) the same way that animals do. The difference is that during the day, plants also perform photosynthesis, in which they take in carbon dioxide and give off oxygen.Plants require oxygen for respiration to carry out their functions of water and nutrient uptake. In soil adequate oxygen is usually available, but plant roots growing in water will quickly exhaust the supply of dissolved oxygen and can be damaged or killed unless additional air is provided. A common method of supplying oxygen is to bubble air through the solution. It is not usually necessary to provide supplementary oxygen in aeroponic or continuous flow systems.Oxygen is vital ingredient in plant survival

What is the table of science?
oee [108]

I think you are refering to the periodic table. The periodic table is important because it is organized to provide a great deal of information about elements and how they relate to one another in one easy-to-use reference. The table can be used to predict the properties of elements, even those that have not yet been discovered.

Using the product rule of probability, calculate the odds of getting an individual that receives the bb genotype and therefore s
Pepsi [2]

Answer:

B) 1/2 X 1/2 = 1/4

Explanation:

It happens when both the parents are heterozygous for the trait. The cross related to this result is shown as under:

                          Father           Mother

                             Bb       x        Bb

                             /   \                 /   \

Gametes:           B      b            B      b

                          |        |              |       |

Probability:      1/2     1/2          1/2    1/2

The probability of formation of 'b' gamete from father is 1/2 because there are only two gametes 'B' and 'b' and out of these two one will be assorted as 'B' and another one as 'b' and from mother also the probability of formation of 'b' gamete is 1/2.

Now the assortment of gametes with each other is an independent event i.e. any gamete from father can fuse with any gamete of mother so the overall probability of formation of 'bb' genotype will be 1/2 x 1/2 = 1/4.

Describes a diploid organism or cell that has the same allele for both a maternal and paternal gene.
Sergeu [11.5K]

When two paired chromosomes harbor the same or identical alleles for a given characteristic at nearby loci, this condition is referred to as homologous (i.e. homologous chromosomes)a diploid organism or cell that has the same allele for both a maternal and paternal gene.

The term "homozygous" refers to the presence of the same or identical alleles for a given trait at related loci on paired chromosomes (i.e. homologous chromosomes). An entity with two sets of chromosomes is said to be diploid. Both sets are inherited; one set is from the mother and the other from the father. Based on their locations, each maternal chromosome can be matched with a corresponding paternal chromosome. Homozygous occurs when the same alleles are present at the loci in the corresponding chromosomes. It indicates that the same trait is coded for by both alleles.

A "homozygous" organism is one that carries two copies of either a pair of dominant alleles (such as AA) or a pair of recessive alleles for a given trait. genuinely reproducing organisms
