Ans.
Testes and ovaries are male and female reproductive organs, respectively. These organs are similiar as testes produce male gametes or sperms by the process of spermatogenesis and ovaries produce female gametes or ova by the process of oogenesis.
These gametes fuse together to form zygote that develops into a multicellular organism. Thus, the correct answer is 'option A). both produce sex cells.'

<u>Answer</u>:
1. The purpose of the uninoculated control tubes used in the oxidation fermentation test is to serve as basis of the medium for the color comparison and that it is sterile.
2. It is necessary to use two controls in order to illustrate the no color change (green color) under both aerobic and anaerobic conditions.
3. The purpose of the experiment is to determine if the organisms utilize the carbohydrate and thus is fermentative. This will result in a color change from green to yellow.
Thus, the medium in one tube is sealed with a layer of paraffin to prevent diffusion of oxygen. This tube will show that the medium is unaffected by the lack of oxygen.
The second tube will allow the diffusion of oxygen. This tube will show that the medium does not change color naturally in the presence of oxygen. Thus, the color changes will be caused only by the fermentation process of the organisms.
Point suspension occurs when one receives too many points against driving record within a given period of time, therefore one will end up loosing his/her driving licence through an accumulation of excess points. This happens such that each time one is convicted of a driving violation the court notifies the DMV (division of motor vehicles) electronically thus keeping truck on the number of times one has made such violations. Therefore, it is true that rough estimates that point suspension of the driver's license can average between $3,000+ to $11,000+.
