When chiasmata can first be seen in cells using a microscope, the following processes has most likely occurred in prophase I.
<h3>When chiasmata can first be seen in cells using a microscope?</h3>
Recombination can occur at any two chromatids within this tetrad structure.
Crossovers between homologous chromatids can be visualized in structures known as chiasmata, which appear late in prophase I.
Thus, option "C" is correct, Prophase I.

Individuals in selective breeding should be of the similar species. Scientists use GMO to generate new gene combinations. Genes pair on their own through selective breeding.
<h3>What is genetic modification?</h3>
A technique to change the characteristics of a plant, animal, or microorganism by swapping a piece of DNA from one organism to an another organism is referred to as gene modification.
Selective breeding entails selecting parents with specific characteristics to breed with in order to generate offspring with more desirable characteristics.
Individuals in selective breeding should be of a similar species. Scientists use GMOs to generate new gene combinations. Genes pair on their own through selective breeding.
Thus, this is the difference between selective breeding and genetic modification.

Most fish need a minimum of 4 parts per million of dissolved oxygen in seawater to survive for long periods.
<h3>How can you mesure dissolved oxygen in water?</h3>
Dissolved oxygen (DO) is estimated utilizing a disintegrated oxygen meter or DO meter. The best strategy is to take the estimation in the field simultaneously every day, in light of the fact that DO fixations can shift all through a 24 hour time span.
Testing disintegrated oxygen (DO) in water is either estimated by means of substance examination, for example, a titrimetric technique, electroanalytical utilizing galvanic and polarographic tests, optical broke up oxygen, and colorimetric strategies.
In any case, present day procedures basically utilize electrochemical or optical sensor techniques.
The Winkler Method is a procedure used to quantify broke up oxygen in freshwater frameworks. Disintegrated oxygen is utilized as a mark of the wellbeing of a water body, where higher broke up oxygen fixations are corresponded with high efficiency and little contamination.
Disintegration of natural material,Bacterial oxidation of dead natural material consumes oxygen. This likewise makes sense of the relating expansion in supplement levels underneath the epipelagic zone.
