Answer:

The correct option is B. Activation energy

Explanation:

The activation energy is usually used to designate the minimum energy necessary for a given chemical reaction to occur, that is, the basic requirement for the reaction to proceed.

For a reaction to occur between two molecules, they must collide in the correct orientation and have a minimum amount of energy. As the molecules approach, their electron clouds are rejected. This requires energy (activation energy) and comes from the heat of the system, that, is, from translational, vibrational energy, etc of each molecule. If the energy is sufficient, the repulsion is overcome and the molecules are close enough for a rearrangement of the bonds of the molecules.

The concept of Activation energy was introduced by Arrhenius in 1889. Arrhenius suggested that molecules must prossess a minimum amount of energy to react. That energy comes from the kinetic energy of the clliding molecules. Kinetic energy serves to cause reactions, but if the molecules move very slowly, the molecules will only bounce when they collide with other molecules and the reaction does not happen. In order for the molecules to react, they must have a total kinetic energy that is equal to or greater than a certain minimum value of energy called activation energy.

Kay [80]

Answer:

<h2>Mitosis and meiosis are the ways of cell division which result daughter cells for growth, development and reproduction. </h2>

Explanation:

Mitosis and meiosis result daughter cells for growth, development and reproduction in the living world.

Mitosis results two similar daughter cells which are generally for growth and development. In asexual mode of reproduction, mitosis helps in increasing the number of cells.

Meiosis occurs in germ cells, and in meiosis, one diploid cell produce four haploid cells.

Meiosis results variations by independent assortment and by crossing over and it helps the sexual mode of reproduction. During fertilization, the resultant daughter haploid cells unite and retains the diploid number of chromosomes.

Answer:

1) bay - 0%

  cream - 0%

  buckskin - 100%

2) cream - 25%

    bay - 25%

   buckskin - 50%

3) co-dominance

Explanation:

Ok so a run down on Punnett Squares,  all you have to do is put the parent's genes on the top and right hand side and combine those two genes in the middle as I did in the picture.  Now, co-dominance, this basically means that there is no dominant allele.  For example, imagine a white flower (W) and a red flower (R).  If these two plants were to breed, you would get a pink flower (WR).  This means the red allele and the white allele are both co-dominant.  It is basically a combination of both genes that result in a mixed phenotype of the two genes, aka red and white makes pink.  This is also how you get an AB blood type.

I hope this helps!
