<u>Answer:</u>

<em>Various sanitation practices changed as a result of germ theory of disease. </em>

<u>Explanation:</u>

<em>Germ theory states that germs are the causative organisms of various diseases.</em> Germs include several microbes like bacteria, fungi, virus, protozoa etc. These microbes invade the host body and multiply inside the host body.  

Prior to germ theory there were several other theories like the miasma theory but the discovery of microbes proved them to be  false. <em>Germ theory brought several changes in sanitation practices and thus has several applications. </em>

John snow an English physician who studied cholera suggested that the <em>transmission was through water contaminated by the faecal matter of infected people. </em>

This discovery gave the idea that sanitation practices have to be improved. The disinfection of surgical instruments is also an improvement that was made in <em>sanitary practices after the formation and acceptance of germ theory.  </em>

You are maintaining a small population of fruit flies in the laboratory by transferring a small number of the flies to a new cul
Lesechka [4]

Answer:

Cross the flies with the flies from another population

Explanation:

Inbreeding is the mating between the closely related individuals of a population. Inbreeding reduces the viability of the progeny over a generation since it increases homozygosity. When the flies of a small population interbred over generations, the increased homozygosity reduces the viability of the flies. To counteract it, one should mate these flies with the flies from another population. This would increase heterozygosity and thereby would increase the survival and fitness of the progeny.

Emily has been asked to find out how
Juliette [100K]

She should investigate how temperature affects the rate of oxygen production.

<h3>Photosynthesis</h3>

During photosynthesis, green plants make use of inorganic products in the form of water and carbon dioxide to synthesize carbohydrates. The reaction only happens in the presence of solar radiation and oxygen is evolved as a by-product.

The process involves a series of chemical reactions. However, the summary of the whole reactions is represented by the following equation:

carbon dioxide + water ----> glucose + oxygen

Thus, if Emily is to find out how temperature affects photosynthesis. She will need to use a plant as a case study. One factor that can easily be used to measure the rate of photosynthesis is oxygen production by plants.

In other words, Emily will have to set up an experiment where a plant species will be subjected to the same environmental conditions, except temperature. Then, a suitable method will be used to measure the amount of oxygen produced. Any difference in the volume of oxygen produced can then be attributed to the effects of temperature.

A normal female X H X H marries a man who has hemophilia.
Citrus2011 [14]

Answer:

0%

Explanation:

Normal female genotype = X^HX^H

Genotype of a man with hemophilia = X^hY

Crossing the two in marriage:

X^HX^H   x   X^hY

Progeny: X^HX^h, X^HY, X^HX^h, and X^HY

<em>The two sons from the cross have the genotype </em>X^HY<em> and are therefore free from hemophilia.</em>

Hence, the percentage of their sons that will have hemophilia is zero (0).
