Answer: Increase intake of fruits and vegetables
Increase intake of beans and legumes
Explanation: Constipation is health condition in which the movements of stool passage and bowel movement becomes slow. It causes pain in stomach , stools with blood etc.
To get rid of this situation fiber intake should be adequate and drinking water is also necessary. Consumption of food like vegetables fruits(apple, kiwifruit etc ),beans etc will reduce the constipation.
Other options are incorrect because milk, cheese ,pasta lean meat ,bread etc are the product that belong to the category of dairy, fat etc which does not soothe the digesting process while constipation rather reduces the fiber amount in body .
Local Leaders would be correct.
(B, local leaders)
1. Samples of a microbial colony obtained from the natural environment are not pure culture. They are mixed cultures because the environment consists of an array of microorganisms and not one specific organism. A sample obtained from the natural environment such as water or soil may contain several species of microbes that need to be further isolated to obtain a pure culture.
2. Isolation streak plate technique involves the dilution of the sample several folds and then streaking a small amount using a sterile inoculation loop on an agar plate in a zig-zag manner. This is done to obtain a pure culture of bacteria from a mixed population by separating the microprocessor. When the sample is diluted into a small concentration and is streaked onto agar placed, widely spaced, discrete colonies of bacteria can be observed. These isolated colonies can be further cultured to obtain pure cultures by picking and re-streaking them on fresh agar plates.
3. A microbial colony is considered a pure culture because it consists of single species. A single species of bacteria cluster and form an isolated colony on an agar plate which can be further plated on fresh medium.
3-1 - If your agar plate shows discrete uncluttered colonies then you have obtained an isolated colony. The following picture might help you to understand.
3-2. If you subculture isolated microbes into a sterile nutrient broth without any contamination, it will still be considered pure culture because it is single isolated species in a sterile aseptic environment of the nutrient broth.
3.3. A pure culture can become a mixed culture due to contamination. This could be caused by airborne bacteria if your conditions are not aseptic. Contamination is possible if the work area is not clean and sterile or if the glassware is not sterile. The contamination can transform your pure culture into a mixed culture and is hence problematic. So, it is very important to maintain a sterile and aseptic environment, glassware, and instruments.

Answer:
Regulatory Marker
Explanation:
Danger: A white buoy or sign with an orange diamond warns boaters of danger – rocks, dams, rapids, etc. ... Controlled Area: A white buoy or sign with an orange circle and black lettering indicates controlled or restricted areas on the water.
Regulatory markers are another buoy on the lakes and rivers of Georgia.The use orange marking and black lettering on a white buoy to warns the hazards and the obstruction or to give direction and information. They also mark closed area.
The restricted buoy is white one that has an orange circle in which there is black lettering. It also has the orange circling at the top and the bottom of the buoy. this tells of an area where there are navigational rules. No Speeding, No Fishing, No Anchoring and No Skiing is the common examples.
