Where they have there effect on the tissues cells
Answer:
b. Sufficient concentration and correct orientation of particles
Explanation:
Collision theory states that when two suitable particles states that when suitable particles of the reactant collide with other and causes any noticeable chemical change, these successful changes are called collisions.
<em>Two factors that responsible for collision are reactant concentration and correct orientation of particles. </em>
<u>Reactant concentration:</u><u> </u>higher concentration of reaction will increase the rate of reaction as, it will provide more reactant to collide in a specific time period.
<u>Orientation of particles:</u> the correct orientation of particles facilitate the forming and breaking of bonds and arrange the atoms to form product molecules.
Hence, the correct option is "Sufficient concentration and correct orientation of particles "
You mean histology right??
Histology:
Histology, also microanatomy, is the ponder of the life structures of cells and tissues of plants and creatures utilizing microscopy.
Answer:
Option (1), (2) and (3).
Explanation:
DNA is the genetic material of all the living organisms present on earth. The DNA contains the nitrogenous bases, pentose sugar and the phosphate group. DNA strands runs in the opposite direction and shows polarity.
Watson and Crick explain the structure of DNA based on the X ray diffraction produced by Rosalind. According to the structure, chromosomes are present in the nucleus and contains the DNA and wrapped around the proteins. The genes is considered as the functional segment of DNA.
Thus, the correct answer is option (1), (2) and (3).
