In the 1950s, the discovery of molecular structure of DNA revolutionized biotechnology.
Hope this helps chu
Have a great day
The correct option is A ie the process whereby non-sister chromatids exchange genetic material
- Between prophase I and metaphase I, a process known as crossing over occurs in which two homologous non-sister chromatids join up and exchange various pieces of genetic material to create two recombinant chromosome sister chromatids.
- When genetic material is switched between two chromosomes, this process is known as crossing over.
- It is in charge of causing genetic variation among members of a species.
- Only the reproductive cells known as gametes undergo this process.
- The steps involved in crossing over are as follows:
1) Synapsis.
2) Chromosome duplication
3) Crossing over.
4) Terminalizataion.

In the light-harvesting complexes, no electrons are passed between the pigment molecules at a time.
Answer: ZERO (0)
Chlorophyll is the light harvesting pigment which makes the light-harvesting complex during the process of photosynthesis. The photosynthesis process is characterized by two reactions: light reaction and dark reaction. During the light reaction, the pigment absorbs light and it becomes excited and photons are released that further carry out the reactions. In this step, the electrons are only excited, not transferred in the reaction.
Answer:
Bond energy is the amount of energy that breaks a bond. Energy is added to break bonds and energy is also released when bonds form. ... In an exothermic reaction, the products have (more or less) energy than the reactants.
Explanation:
Hey!
The water cycle is driven by solar energy, see solar energy is what makes water evaporate, which needs to happen for precipitation to happen, and precipitation reaches earth in hail, snow, or rain which will run-off into oceans and evaporate or just eventually evaporate.
So, yes, solar.
